american health packaging - duloxetine hydrochloride (unii: 9044sc542w) (duloxetine - unii:o5tnm5n07u) - duloxetine delayed-release capsules are indicated for the treatment of: - major depressive disorder in adults - generalized anxiety disorder in adults and pediatric patients 7 years of age and older - diabetic peripheral neuropathic pain in adults - fibromyalgia in adults - chronic musculoskeletal pain in adults additional pediatric use information is approved for eli lilly and company, inc.’s cymbalta (duloxetine) delayed-release capsules. however, due to eli lilly and company inc.’s marketing exclusivity rights, this drug product is not labeled with that pediatric information. the use of maois intended to treat psychiatric disorders with duloxetine delayed-release capsules or within 5 days of stopping treatment with duloxetine delayed-release capsules is contraindicated because of an increased risk of serotonin syndrome. the use of duloxetine delayed-release capsules within 14 days of stopping an maoi intended to treat psychiatric disorders is contraindicated [see dosage and administration (2.8) and warnings and precautions (5.4)]. starting duloxetine delayed-release capsules in a patient who is being treated with maois such as linezolid or intravenous methylene blue is also contraindicated because of an increased risk of serotonin syndrome [see dosage and administration (2.9) and warnings and precautions (5.4)]. risk summary data from a postmarketing retrospective cohort study indicate that use of duloxetine in the month before delivery may be associated with an increased risk of postpartum hemorrhage. data from published literature and from a postmarketing retrospective cohort study have not identified a clear drug-associated risk of major birth defects or other adverse developmental outcomes (see data) . there are risks associated with untreated depression and fibromyalgia in pregnancy, and with exposure to snris and ssris, including duloxetine delayed-release capsules, during pregnancy (see clinical considerations) . in rats and rabbits treated with duloxetine during the period of organogenesis, fetal weights were decreased but there was no evidence of developmental effects at doses up to 3 and 6 times, respectively, the maximum recommended human dose (mrhd) of 120 mg/day given to adolescents on a mg/m 2 basis. when duloxetine was administered orally to pregnant rats throughout gestation and lactation, pup weights at birth and pup survival to 1 day postpartum were decreased at a dose 2 times the mrhd given to adolescents on a mg/m 2 basis. at this dose, pup behaviors consistent with increased reactivity, such as increased startle response to noise and decreased habituation of locomotor activity were observed. post-weaning growth was not adversely affected. the estimated background risk of major birth defects and miscarriage for the indicated population is unknown. all pregnancies have a background risk of birth defect, loss, or other adverse outcomes. in the u.s. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. clinical considerations disease-associated maternal and/or embryo/fetal risk women who discontinue antidepressants during pregnancy are more likely to experience a relapse of major depression than women who continue antidepressants. this finding is from a prospective, longitudinal study that followed 201 pregnant women with a history of major depressive disorder who were euthymic and taking antidepressants at the beginning of pregnancy. consider the risk of untreated depression when discontinuing or changing treatment with antidepressant medication during pregnancy and postpartum. pregnant women with fibromyalgia are at increased risk for adverse maternal and infant outcomes including preterm premature rupture of membranes, preterm birth, small for gestational age, intrauterine growth restriction, placental disruption, and venous thrombosis. it is not known if these adverse maternal and fetal outcomes are a direct result of fibromyalgia or other comorbid factors. maternal adverse reactions use of duloxetine in the month before delivery may be associated with an increased risk of postpartum hemorrhage [see warnings and precautions (5.5)]. fetal/neonatal adverse reaction neonates exposed to duloxetine delayed-release capsules and other snris or ssris late in the third trimester have developed complications requiring prolonged hospitalization, respiratory support, and tube feeding. such complications can arise immediately upon delivery. reported clinical findings have included respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycemia, hypotonia, hypertonia, hyperreflexia, tremor, jitteriness, irritability, and constant crying. these findings are consistent with either a direct toxic effect of the snris or ssris, or possibly, a drug discontinuation syndrome. it should be noted that, in some cases, the clinical picture is consistent with serotonin syndrome [see warnings and precautions (5.4)]. data human data data from a postmarketing retrospective claims-based cohort study found an increased risk for postpartum hemorrhage among 955 pregnant women exposed to duloxetine in the last month of pregnancy compared to 4,128,460 unexposed pregnant women (adjusted relative risk: 1.53; 95% ci: 1.08 to 2.18). the same study did not find a clinically meaningful increase in the risk for major birth defects in the comparison of 2532 women exposed to duloxetine in the first trimester of pregnancy to 1,284,827 unexposed women after adjusting for several confounders. methodologic limitations include possible residual confounding, misclassification of exposure and outcomes, lack of direct measures of disease severity, and lack of information about alcohol use, nutrition, and over-the-counter medication exposures. animal data in animal reproduction studies, duloxetine has been shown to have adverse effects on embryo/fetal and postnatal development. when duloxetine was administered orally to pregnant rats and rabbits during the period of organogenesis, there was no evidence of malformations or developmental variations at doses up to 45 mg/kg/day [3 and 6 times, respectively, the mrhd of 120 mg/day given to adolescents on a mg/m 2 basis]. however, fetal weights were decreased at this dose, with a no-effect dose of 10 mg/kg/day (approximately equal to the mrhd in rats and 2 times the mrhd in rabbits). when duloxetine was administered orally to pregnant rats throughout gestation and lactation, the survival of pups to 1 day postpartum and pup body weights at birth and during the lactation period were decreased at a dose of 30 mg/kg/day (2 times the mrhd given to adolescents on a mg/m 2 basis); the no-effect dose was 10 mg/kg/day. furthermore, behaviors consistent with increased reactivity, such as increased startle response to noise and decreased habituation of locomotor activity, were observed in pups following maternal exposure to 30 mg/kg/day. post-weaning growth and reproductive performance of the progeny were not affected adversely by maternal duloxetine treatment. risk summary data from published literature report the presence of duloxetine in human milk (see data) . there are reports of sedation, poor feeding, and poor weight gain in infants exposed to duloxetine through breast milk (see clinical considerations) . there are no data on the effect of duloxetine on milk production. the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for duloxetine delayed-release capsules and any potential adverse effects on the breastfed child from duloxetine delayed-release capsules or from the underlying maternal condition. clinical considerations infants exposed to duloxetine delayed-release capsules should be monitored for sedation, poor feeding and poor weight gain. data disposition of duloxetine delayed-release capsules was studied in 6 lactating women who were at least 12 weeks postpartum and had elected to wean their infants. the women were given 40 mg of duloxetine delayed-release capsules twice daily for 3.5 days. the peak concentration measured in breast milk occurred at a median of 3 hours after the dose. the amount of duloxetine delayed-release capsules in breast milk was approximately 7 mcg/day while on that dose; the estimated daily infant dose was approximately 2 mcg/kg/day, which is less than 1% of the maternal dose. the presence of duloxetine delayed-release capsules metabolites in breast milk was not examined. the safety and effectiveness of duloxetine delayed-release capsules have been established for treatment of generalized anxiety disorder (gad) in patients 7 to 17 years of age. the safety and effectiveness of duloxetine delayed-release capsules have not been established in pediatric patients with major depressive disorder (mdd), diabetic peripheral neuropathic pain, or chronic musculoskeletal pain. antidepressants increased the risk of suicidal thoughts and behavior in pediatric patients. monitor all pediatric patients being treated with antidepressants for clinical worsening and emergence of suicidal thoughts and behaviors, especially during the initial few months of treatment, or at times of dosage changes [see warnings and precautions (5.1)]. perform regular monitoring of weight and growth in pediatric patients treated with duloxetine delayed-release capsules [see adverse reactions (6.1)]. generalized anxiety disorder use of duloxetine delayed-release capsules for the treatment of gad in patients 7 to 17 years of age is supported by one 10-week, placebo-controlled trial (gad-6). the study included 272 pediatric patients with gad of which 47% were 7 to 11 years of age (53% were 12 to 17 years of age). duloxetine delayed-release capsules demonstrated superiority over placebo as measured by greater improvement in the pediatric anxiety rating scale (pars) for gad severity score [see clinical studies (14.3)]. the safety and effectiveness of duloxetine delayed-release capsules for the treatment of gad in pediatric patients less than 7 years of age have not been established. fibromyalgia the safety and effectiveness of duloxetine delayed-release capsules for the treatment of fibromyalgia in patients less than 13 years of age have not been established. major depressive disorder the safety and effectiveness of duloxetine delayed-release capsules have not been established in pediatric patients for the treatment of mdd. efficacy of duloxetine delayed-release capsules was not demonstrated in two 10-week, placebo-controlled trials with 800 pediatric patients aged 7 to 17 years old with mdd (mdd-6 and mdd-7). neither duloxetine delayed-release capsules nor an active control (approved for treatment of pediatric mdd) was superior to placebo. the most frequently observed adverse reactions in the mdd pediatric clinical trials included nausea, headache, decreased weight, and abdominal pain. decreased appetite and weight loss have been observed in association with the use of ssris and snris. juvenile animal toxicology data duloxetine administration to young rats from post-natal day 21 (weaning) through post-natal day 90 (adult) resulted in decreased body weights that persisted into adulthood, but recovered when drug treatment was discontinued; slightly delayed (~1.5 days) sexual maturation in females, without any effect on fertility; and a delay in learning a complex task in adulthood, which was not observed after drug treatment was discontinued. these effects were observed at the high dose of 45 mg/kg/day (2 times the mrhd, for a child); the no-effect-level was 20 mg/kg/day (≈1 times the mrhd, for a child). additional pediatric use information is approved for eli lilly and company, inc.’s cymbalta (duloxetine) delayed-release capsules. however, due to eli lilly and company inc.’s marketing exclusivity rights, this drug product is not labeled with that pediatric information. geriatric exposure in premarketing clinical trials of duloxetine delayed-release capsules - of the 2,418 patients in mdd trials, 6% (143) were 65 years of age or over. - of the 1041 patients in clbp trials, 21% (221) were 65 years of age or over. - of the 487 patients in oa trials, 41% (197) were 65 years of age or over. - of the 1,074 patients in the dpnp trials, 33% (357) were 65 years of age or over. - of the 1,761 patients in fm trials, 8% (140) were 65 years of age or over. in the mdd, gad, dpnp, fm, oa, and clbp studies, no overall differences in safety or effectiveness were generally observed between these patients and younger adult patients, and other reported clinical experience has not identified differences in responses between these geriatric and younger adult patients, but greater sensitivity of some older patients cannot be ruled out. ssris and snris, including duloxetine delayed-release capsules have been associated with clinically significant hyponatremia in geriatric patients, who may be at greater risk for this adverse reaction [see warnings and precautions (5.13)]. in an analysis of data from all placebo-controlled-trials, duloxetine delayed-release capsules-treated patients reported a higher rate of falls compared to placebo-treated patients. the increased risk appears to be proportional to a patient’s underlying risk for falls. underlying risk appears to increase steadily with age. as geriatric patients tend to have a higher prevalence of risk factors for falls such as medications, medical comorbidities and gait disturbances, the impact of increasing age by itself on falls during duloxetine delayed-release capsules treatment is unclear. falls with serious consequences including bone fractures and hospitalizations have been reported with duloxetine delayed-release capsules use [see warnings and precautions (5.3) and adverse reactions (6.1)]. the pharmacokinetics of duloxetine after a single dose of 40 mg were compared in healthy elderly females (65 to 77 years) and healthy middle-age females (32 to 50 years). there was no difference in the c max , but the auc of duloxetine was somewhat (about 25%) higher and the half-life about 4 hours longer in the elderly females. population pharmacokinetic analyses suggest that the typical values for clearance decrease by approximately 1% for each year of age between 25 to 75 years of age; but age as a predictive factor only accounts for a small percentage of between-patient variability. dosage adjustment based on the age of the adult patient is not necessary. duloxetine’s half-life is similar in men and women. dosage adjustment based on gender is not necessary. duloxetine bioavailability (auc) appears to be reduced by about one-third in smokers. dosage modifications are not recommended for smokers. no specific pharmacokinetic study was conducted to investigate the effects of race. patients with clinically evident hepatic impairment have decreased duloxetine metabolism and elimination. after a single 20 mg dose of duloxetine delayed-release capsules, 6 cirrhotic patients with moderate liver impairment (child-pugh class b) had a mean plasma duloxetine clearance about 15% that of age- and gender-matched healthy subjects, with a 5-fold increase in mean exposure (auc). although c max was similar to normals in the cirrhotic patients, the half-life was about 3 times longer [see dosage and administration (2.7) and warnings and precautions (5.14)]. limited data are available on the effects of duloxetine delayed-release capsules in patients with end-stage renal disease (esrd). after a single 60 mg dose of duloxetine delayed-release capsules, c max and auc values were approximately 100% greater in patients with esrd receiving chronic intermittent hemodialysis than in subjects with normal renal function. the elimination half-life, however, was similar in both groups. the aucs of the major circulating metabolites, 4-hydroxy duloxetine glucuronide and 5-hydroxy, 6-methoxy duloxetine sulfate, largely excreted in urine, were approximately 7- to 9-fold higher and would be expected to increase further with multiple dosing. population pk analyses suggest that mild to moderate degrees of renal impairment (estimated crcl 30 to 80 ml/min) have no significant effect on duloxetine apparent clearance [see dosage and administration (2.7) and warnings and precautions (5.14)]. in animal studies, duloxetine did not demonstrate barbiturate-like (depressant) abuse potential. while duloxetine delayed-release capsules have not been systematically studied in humans for its potential for abuse, there was no indication of drug-seeking behavior in the clinical trials. however, it is not possible to predict on the basis of premarketing experience the extent to which a cns active drug will be misused, diverted, and/or abused once marketed. consequently, physicians should carefully evaluate patients for a history of drug abuse and follow such patients closely, observing them for signs of misuse or abuse of duloxetine delayed-release capsules (e.g., development of tolerance, incrementation of dose, drug-seeking behavior). in drug dependence studies, duloxetine did not demonstrate dependence-producing potential in rats.

american health packaging - meloxicam (unii: vg2qf83cgl) (meloxicam - unii:vg2qf83cgl) - meloxicam 15 mg - meloxicam tablets are indicated for relief of the signs and symptoms of osteoarthritis [see clinical studies (14.1)]. meloxicam tablets are indicated for relief of the signs and symptoms of rheumatoid arthritis [see clinical studies (14.1)]. meloxicam tablets are indicated for relief of the signs and symptoms of pauciarticular or polyarticular course juvenile rheumatoid arthritis in patients who weigh ≥60 kg [see dosage and administration (2.4) and clinical studies (14.2)]. meloxicam is contraindicated in the following patients: - known hypersensitivity (e.g., anaphylactic reactions and serious skin reactions) to meloxicam or any components of the drug product [see warnings and precautions (5.7, 5.9)] - history of asthma, urticaria, or other allergic-type reactions after taking aspirin or other nsaids. severe, sometimes fatal, anaphylactic reactions to nsaids have been reported in such patients [see warnings and precautions (5.7, 5.8)] - in the setting of coronary artery bypass graft (cabg) surgery [see warnings and precautions (5.1)] risk summary use of nsaids, including meloxicam, can cause premature closure of the fetal ductus arteriosus and fetal renal dysfunction leading to oligohydramnios and, in some cases, neonatal renal impairment. because of these risks, limit dose and duration of meloxicam use between about 20 and 30 weeks of gestation, and avoid meloxicam use at about 30 weeks of gestation and later in pregnancy (see clinical considerations, data). premature closure of fetal ductus arteriosus use of nsaids, including meloxicam, at about 30 weeks gestation or later in pregnancy increases the risk of premature closure of the fetal ductus arteriosus. oligohydramnios/neonatal renal impairment use of nsaids at about 20 weeks gestation or later in pregnancy has been associated with cases of fetal renal dysfunction leading to oligohydramnios, and in some cases, neonatal renal impairment. data from observational studies regarding potential embryofetal risks of nsaid use in women in the first or second trimesters of pregnancy are inconclusive. in animal reproduction studies, embryofetal death was observed in rats and rabbits treated during the period of organogenesis with meloxicam at oral doses equivalent to 0.65- and 6.5-times the maximum recommended human dose (mrhd) of meloxicam. increased incidence of septal heart defects were observed in rabbits treated throughout embryogenesis with meloxicam at an oral dose equivalent to 78-times the mrhd. in pre- and post-natal reproduction studies, there was an increased incidence of dystocia, delayed parturition, and decreased offspring survival at 0.08-times mrhd of meloxicam. no teratogenic effects were observed in rats and rabbits treated with meloxicam during organogenesis at an oral dose equivalent to 2.6 and 26-times the mrhd [see data]. based on animal data, prostaglandins have been shown to have an important role in endometrial vascular permeability, blastocyst implantation, and decidualization. in animal studies, administration of prostaglandin synthesis inhibitors, such as meloxicam, resulted in increased pre- and post-implantation loss. prostaglandins also have been shown to have an important role in fetal kidney development. in published animal studies, prostaglandin synthesis inhibitors have been reported to impair kidney development when administered at clinically relevant doses. the estimated background risk of major birth defects and miscarriage for the indicated population(s) is unknown. all pregnancies have a background risk of birth defect, loss, or other adverse outcomes. in the u.s. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. clinical considerations fetal/neonatal adverse reactions premature closure of fetal ductus arteriosus: avoid use of nsaids in women at about 30 weeks gestation and later in pregnancy, because nsaids, including meloxicam, can cause premature closure of the fetal ductus arteriosus (see data). oligohydramnios/neonatal renal impairment: if an nsaid is necessary at about 20 weeks gestation or later in pregnancy, limit the use to the lowest effective dose and shortest duration possible. if meloxicam treatment extends beyond 48 hours, consider monitoring with ultrasound for oligohydramnios. if oligohydramnios occurs, discontinue meloxicam and follow up according to clinical practice (see data). labor or delivery there are no studies on the effects of meloxicam during labor or delivery. in animal studies, nsaids, including meloxicam, inhibit prostaglandin synthesis, cause delayed parturition, and increase the incidence of stillbirth. data human data premature closure of fetal ductus arteriosus: published literature reports that the use of nsaids at about 30 weeks of gestation and later in pregnancy may cause premature closure of the fetal ductus arteriosus. oligohydramnios/neonatal renal impairment: published studies and postmarketing reports describe maternal nsaid use at about 20 weeks gestation or later in pregnancy associated with fetal renal dysfunction leading to oligohydramnios, and in some cases, neonatal renal impairment. these adverse outcomes are seen, on average, after days to weeks of treatment, although oligohydramnios has been infrequently reported as soon as 48 hours after nsaid initiation. in many cases, but not all, the decrease in amniotic fluid was transient and reversible with cessation of the drug. there have been a limited number of case reports of maternal nsaid use and neonatal renal dysfunction without oligohydramnios, some of which were irreversible. some cases of neonatal renal dysfunction required treatment with invasive procedures, such as exchange transfusion or dialysis. methodological limitations of these postmarketing studies and reports include lack of a control group; limited information regarding dose, duration, and timing of drug exposure; and concomitant use of other medications. these limitations preclude establishing a reliable estimate of the risk of adverse fetal and neonatal outcomes with maternal nsaid use. because the published safety data on neonatal outcomes involved mostly preterm infants, the generalizability of certain reported risks to the full-term infant exposed to nsaids through maternal use is uncertain. animal data meloxicam was not teratogenic when administered to pregnant rats during fetal organogenesis at oral doses up to 4 mg/kg/day (2.6-fold greater than the mrhd of 15 mg of meloxicam based on bsa comparison). administration of meloxicam to pregnant rabbits throughout embryogenesis produced an increased incidence of septal defects of the heart at an oral dose of 60 mg/kg/day (78-fold greater than the mrhd based on bsa comparison). the no effect level was 20 mg/kg/day (26-fold greater than the mrhd based on bsa conversion). in rats and rabbits, embryolethality occurred at oral meloxicam doses of 1 mg/kg/day and 5 mg/kg/day, respectively (0.65and 6.5-fold greater, respectively, than the mrhd based on bsa comparison) when administered throughout organogenesis. oral administration of meloxicam to pregnant rats during late gestation through lactation increased the incidence of dystocia, delayed parturition, and decreased offspring survival at meloxicam doses of 0.125 mg/kg/day or greater (0.08-times mrhd based on bsa comparison). risk summary there are no human data available on whether meloxicam is present in human milk, or on the effects on breastfed infants, or on milk production. the developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for meloxicam and any potential adverse effects on the breastfed infant from the meloxicam or from the underlying maternal condition. data animal data meloxicam was present in the milk of lactating rats at concentrations higher than those in plasma. infertility females based on the mechanism of action, the use of prostaglandin-mediated nsaids, including meloxicam, may delay or prevent rupture of ovarian follicles, which has been associated with reversible infertility in some women. published animal studies have shown that administration of prostaglandin synthesis inhibitors has the potential to disrupt prostaglandin-mediated follicular rupture required for ovulation. small studies in women treated with nsaids have also shown a reversible delay in ovulation. consider withdrawal of nsaids, including meloxicam, in women who have difficulties conceiving or who are undergoing investigation of infertility. the safety and effectiveness of meloxicam in pediatric jra patients from 2 to 17 years of age has been evaluated in three clinical trials [see dosage and administration (2.4), adverse reactions (6.1) and clinical studies (14.2)]. elderly patients, compared to younger patients, are at greater risk for nsaid associated serious cardiovascular, gastrointestinal, and/or renal adverse reactions. if the anticipated benefit for the elderly patient outweighs these potential risks, start dosing at the low end of the dosing range, and monitor patients for adverse effects [see warnings and precautions (5.1, 5.2, 5.3, 5.6, 5.14)]. no dose adjustment is necessary in patients with mild to moderate hepatic impairment. patients with severe hepatic impairment have not been adequately studied. since meloxicam is significantly metabolized in the liver and hepatotoxicity may occur, use meloxicam with caution in patients with hepatic impairment [see warnings and precautions (5.3) and clinical pharmacology (12.3)]. no dose adjustment is necessary in patients with mild to moderate renal impairment. patients with severe renal impairment have not been studied. the use of meloxicam in subjects with severe renal impairment is not recommended. in patients on hemodialysis, meloxicam should not exceed 7.5 mg per day. meloxicam is not dialyzable [see dosage and administration (2.1) and clinical pharmacology (12.3)].

american health packaging - pantoprazole sodium (unii: 6871619q5x) (pantoprazole - unii:d8tst4o562) - pantoprazole 20 mg - pantoprazole sodium delayed-release tablets, usp are indicated for: pantoprazole is indicated in adults and pediatric patients five years of age and older for the short-term treatment (up to 8 weeks) in the healing and symptomatic relief of erosive esophagitis (ee). for those adult patients who have not healed after 8 weeks of treatment, an additional 8-week course of pantoprazole may be considered. safety of treatment beyond 8 weeks in pediatric patients has not been established. pantoprazole is indicated for maintenance of healing of ee and reduction in relapse rates of daytime and nighttime heartburn symptoms in adult patients with gerd. controlled studies did not extend beyond 12 months. pantoprazole is indicated for the long-term treatment of pathological hypersecretory conditions, including zollinger-ellison (ze) syndrome. - pantoprazole is contraindicated in patients with known hypersensitivity to any component of the formulation or any substituted benzimidazole. hypersensitivity reactions may include anaphylaxis, anaphylactic shock, angioedema, bronchospasm, acute tubulointerstitial nephritis, and urticaria [see warnings and precautions (5.2), adverse reactions (6)]. - proton pump inhibitors (ppis), including pantoprazole, are contraindicated in patients receiving rilpivirine-containing products [see drug interactions (7)]. risk summary available data from published observational studies did not demonstrate an association of major malformations or other adverse pregnancy outcomes with pantoprazole. in animal reproduction studies, no evidence of adverse development outcomes was observed with pantoprazole. reproduction studies have been performed in rats at oral doses up to 450 mg/kg/day (about 88 times the recommended human dose) and rabbits at oral doses up to 40 mg/kg/day (about 16 times the recommended human dose) with administration of pantoprazole during organogenesis in pregnant animals and have revealed no evidence of harm to the fetus due to pantoprazole in this study (see data). a pre- and postnatal development toxicity study in rats with additional endpoints to evaluate the effect on bone development was performed with pantoprazole sodium. oral pantoprazole doses of 5, 15, and 30 mg/kg/day (approximately 1, 3, and 6 times the human dose of 40 mg/day) were administered to pregnant females from gestation day (gd) 6 through lactation day (ld) 21. changes in bone morphology were observed in pups exposed to pantoprazole in utero and through milk during the period of lactation as well as by oral dosing from postnatal day (pnd) 4 through pnd 21 [see use in specific populations (8.4)]. there were no drug-related findings in maternal animals. advise pregnant women of the potential risk of fetal harm. the estimated background risk of major birth defects and miscarriage for the indicated population is unknown. all pregnancies have a background risk of birth defect, loss or other adverse outcomes. in the u.s. general population, the estimated background risk of major birth defects and miscarriage in the clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. data human data available data from published observational studies failed to demonstrate an association of adverse pregnancy-related outcomes and pantoprazole use. methodological limitations of these observational studies cannot definitely establish or exclude any drug-associated risk during pregnancy. in a prospective study by the european network of teratology information services, outcomes from a group of 53 pregnant women administered median daily doses of 40 mg pantoprazole were compared to a control group of 868 pregnant women who did not take any proton pump inhibitors (ppis). there was no difference in the rate of major malformations between women exposed to ppis and the control group, corresponding to a relative risk (rr)=0.55, [95%confidence interval (ci) 0.08-3.95]. in a population-based retrospective cohort study covering all live births in denmark from 1996 to 2008, there was no significant increase in major birth defects during analysis of first trimester exposure to pantoprazole in 549 live births. a meta-analysis that compared 1,530 pregnant women exposed to ppis in at least the first trimester with 133,410 unexposed pregnant women showed no significant increases in risk for congenital malformations or spontaneous abortion with exposure to ppis (for major malformations or=1.12 ([95% ci 0.86-1.45] and for spontaneous abortions or=1.29 [95% ci 0.84-1.97]). animal data reproduction studies have been performed in rats at oral pantoprazole doses up to 450 mg/kg/day (about 88 times the recommended human dose based on body surface area) and in rabbits at oral doses up to 40 mg/kg/day (about 16 times the recommended human dose based on body surface area) with administration of pantoprazole sodium during organogenesis in pregnant animals. the studies have revealed no evidence of impaired fertility or harm to the fetus due to pantoprazole. a pre- and postnatal development toxicity study in rats with additional endpoints to evaluate the effect on bone development was performed with pantoprazole sodium. oral pantoprazole doses of 5, 15, and 30 mg/kg/day (approximately 1, 3, and 6 times the human dose of 40 mg/day on a body surface area basis) were administered to pregnant females from gestation day (gd) 6 through lactation day (ld) 21. on postnatal day (pnd 4) through pnd 21, the pups were administered oral doses at 5, 15, and 30 mg/kg/day (approximately 1, 2.3, and 3.2 times the exposure (auc) in humans at a dose of 40 mg). there were no drug-related findings in maternal animals. during the preweaning dosing phase (pnd 4 to 21) of the pups, there were increased mortality and/or moribundity and decreased body weight and body weight gain at 5 mg/kg/day (approximately equal exposures (auc) in humans receiving the 40 mg dose) and higher doses. on pnd 21, decreased mean femur length and weight and changes in femur bone mass and geometry were observed in the offspring at 5 mg/kg/day (approximately equal exposures (auc) in humans at the 40 mg dose) and higher doses. the femur findings included lower total area, bone mineral content and density, periosteal and endosteal circumference, and cross-sectional moment of inertia. there were no microscopic changes in the distal femur, proximal tibia, or stifle joints. changes in bone parameters were partially reversible following a recovery period, with findings on pnd 70 limited to lower femur metaphysis cortical/subcortical bone mineral density in female pups at 5 mg/kg/day (approximately equal exposures (auc) in humans at the 40 mg dose) and higher doses. risk summary pantoprazole has been detected in breast milk of a nursing mother after a single 40 mg oral dose of pantoprazole. there were no effects on the breastfed infant (see data). there are no data on pantoprazole effects on milk production. the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for pantoprazole and any potential adverse effects on the breastfed child from pantoprazole or from the underlying maternal condition. data the breast milk of a 42-year-old woman receiving 40 mg of oral pantoprazole, at 10 months postpartum, was studied for 24 hours, to demonstrate low levels of pantoprazole present in the breast milk. pantoprazole was detectable in milk only 2 and 4 hours after the dose with milk levels of approximately 36 mcg/l and 24 mcg/l, respectively. a milk-to-plasma ratio of 0.022 was observed at 2 hours after drug administration. pantoprazole was not detectable (<10 mcg/l) in milk at 6, 8 and 24 hours after the dose. the relative dose to the infant was estimated to be 7.3 mcg of pantoprazole, which is equivalent to 0.14% of the weight-adjusted maternal dose. no adverse events in the infant were reported by the mother. the safety and effectiveness of pantoprazole for short-term treatment (up to eight weeks) of ee associated with gerd have been established in pediatric patients 1 year through 16 years of age. effectiveness for ee has not been demonstrated in patients less than 1 year of age. in addition, for patients less than 5 years of age, there is no appropriate dosage strength in an age-appropriate formulation available. therefore, pantoprazole is indicated for the short-term treatment of ee associated with gerd for patients 5 years and older. the safety and effectiveness of pantoprazole for pediatric uses other than ee have not been established. 1 year through 16 years of age use of pantoprazole in pediatric patients 1 year through 16 years of age for short-term treatment (up to eight weeks) of ee associated with gerd is supported by: a) extrapolation of results from adequate and well-controlled studies that supported the approval of pantoprazole for treatment of ee associated with gerd in adults, and b) safety, effectiveness, and pharmacokinetic studies performed in pediatric patients [see clinical studies (14.1), clinical pharmacology (12.3)]. safety of pantoprazole in the treatment of ee associated with gerd in pediatric patients 1 through 16 years of age was evaluated in three multicenter, randomized, double-blind, parallel-treatment studies, involving 249 pediatric patients, including 8 with ee (4 patients ages 1 year to 5 years and 4 patients 5 years to 11 years). the children ages 1 year to 5 years with endoscopically diagnosed ee (defined as an endoscopic hetzel-dent score ≥ 2) were treated once daily for 8 weeks with one of two dose levels of pantoprazole (approximating 0.6 mg/kg or 1.2 mg/kg). all 4 of these patients with ee were healed (hetzel-dent score of 0 or 1) at 8 weeks. because ee is uncommon in the pediatric population, predominantly pediatric patients with endoscopically-proven or symptomatic gerd were also included in these studies. patients were treated with a range of doses of pantoprazole once daily for 8 weeks. for safety findings see adverse reactions (6.1). because these pediatric trials had no placebo, active comparator, or evidence of a dose response, the trials were inconclusive regarding the clinical benefit of pantoprazole for symptomatic gerd in the pediatric population. the effectiveness of pantoprazole for treating symptomatic gerd in pediatric patients has not been established. although the data from the clinical trials support use of pantoprazole for the short-term treatment of ee associated with gerd in pediatric patients 1 year through 5 years, there is no commercially available dosage formulation appropriate for patients less than 5 years of age [see dosage and administration (2)]. in a population pharmacokinetic analysis, clearance values in the children 1 to 5 years old with endoscopically proven gerd had a median value of 2.4 l/h. following a 1.2 mg/kg equivalent dose (15 mg for ≤ 12.5 kg and 20 mg for > 12.5 to < 25 kg), the plasma concentrations of pantoprazole were highly variable and the median time to peak plasma concentration was 3 to 6 hours. the estimated auc for patients 1 to 5 years old was 37% higher than for adults receiving a single 40 mg tablet, with a geometric mean auc value of 6.8 mcg∙hr/ml. neonates to less than one year of age pantoprazole was not found to be effective in a multicenter, randomized, double-blind, placebo-controlled, treatment-withdrawal study of 129 pediatric patients 1 through 11 months of age. patients were enrolled if they had symptomatic gerd based on medical history and had not responded to non-pharmacologic interventions for gerd for two weeks. patients received pantoprazole daily for four weeks in an open-label phase, then patients were randomized in equal proportion to receive pantoprazole treatment or placebo for the subsequent four weeks in a double-blind manner. efficacy was assessed by observing the time from randomization to study discontinuation due to symptom worsening during the four-week treatment-withdrawal phase. there was no statistically significant difference between pantoprazole and placebo in the rate of discontinuation. in this trial, the adverse reactions that were reported more commonly (difference of ≥ 4%) in the treated population compared to the placebo population were elevated ck, otitis media, rhinitis, and laryngitis. in a population pharmacokinetic analysis, the systemic exposure was higher in patients less than 1 year of age with gerd compared to adults who received a single 40 mg dose (geometric mean auc was 103% higher in preterm infants and neonates receiving single dose of 2.5 mg of pantoprazole, and 23% higher in infants 1 through 11 months of age receiving a single dose of approximately 1.2 mg/kg). in these patients, the apparent clearance (cl/f) increased with age (median clearance: 0.6 l/hr, range: 0.03 to 3.2 l/hr). these doses resulted in pharmacodynamic effects on gastric but not esophageal ph. following once daily dosing of 2.5 mg of pantoprazole in preterm infants and neonates, there was an increase in the mean gastric ph (from 4.3 at baseline to 5.2 at steady-state) and in the mean % time that gastric ph was > 4 (from 60% at baseline to 80% at steady-state). following once daily dosing of approximately 1.2 mg/kg of pantoprazole in infants 1 through 11 months of age, there was an increase in the mean gastric ph (from 3.1 at baseline to 4.2 at steady-state) and in the mean % time that gastric ph was > 4 (from 32% at baseline to 60% at steady-state). however, no significant changes were observed in mean intraesophageal ph or % time that esophageal ph was < 4 in either age group. because pantoprazole was not shown to be effective in the randomized, placebo-controlled study in this age group, the use of pantoprazole for treatment of symptomatic gerd in infants less than 1 year of age is not indicated. animal toxicity data in a pre- and post-natal development study in rats, the pups were administered oral doses of pantoprazole at 5, 15, and 30 mg/kg/day (approximately 1, 2.3, and 3.2 times the exposure (auc) in children aged 6 to 11 years at a dose of 40 mg) on postnatal day (pnd 4) through pnd 21, in addition to lactational exposure through milk. on pnd 21, decreased mean femur length and weight and changes in femur bone mass and geometry were observed in the offspring at 5 mg/kg/day (approximately equal exposures (auc) in children aged 6 to 11 years at the 40 mg dose) and higher doses. changes in bone parameters were partially reversible following a recovery period. in neonatal/juvenile animals (rats and dogs) toxicities were similar to those observed in adult animals, including gastric alterations, decreases in red cell mass, increases in lipids, enzyme induction and hepatocellular hypertrophy. an increased incidence of eosinophilic chief cells in adult and neonatal/juvenile rats, and atrophy of chief cells in adult rats and in neonatal/juvenile dogs, was observed in the fundic mucosa of stomachs in repeated-dose studies. full to partial recovery of these effects were noted in animals of both age groups following a recovery period. in short-term us clinical trials, ee healing rates in the 107 elderly patients (≥ 65 years old) treated with pantoprazole were similar to those found in patients under the age of 65. the incidence rates of adverse reactions and laboratory abnormalities in patients aged 65 years and older were similar to those associated with patients younger than 65 years of age.

american health packaging - mycophenolate sodium (unii: wx877sqi1g) (mycophenolic acid - unii:hu9dx48n0t) - mycophenolic acid 180 mg - mycophenolic acid are indicated for the prophylaxis of organ rejection in adult patients receiving a kidney transplant. mycophenolic acid are indicated for the prophylaxis of organ rejection in pediatric patients 5 years of age and older who are at least 6 months post kidney transplant. mycophenolic acid are to be used in combination with cyclosporine and corticosteroids. mycophenolic acid delayed-release tablets and mycophenolate mofetil (mmf) tablets and capsules should not be used interchangeably without physician supervision because the rate of absorption following the administration of these two products is not equivalent. mycophenolic acid delayed-release tablets are contraindicated in patients with a hypersensitivity to mycophenolate sodium, mycophenolic acid (mpa), mycophenolate mofetil, or to any of its excipients. reactions like rash, pruritus, hypotension, and chest pain have been observed in clinical trials and post marketing reports [see adverse reactions (6)]. pregnancy exposure registry there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to mycophenolate during pregnancy and those becoming pregnant within 6 weeks of discontinuing mycophenolic acid treatment. to report a pregnancy or obtain information about the registry, visit www.mycophenolaterems.com or call 1-800-617-8191. risk summary following oral or intravenous (iv) administration, mmf is metabolized to mycophenolic acid (mpa), the active ingredient in mycophenolic acid delayed-release tablets and the active form of the drug. use of mmf during pregnancy is associated with an increased risk of first trimester pregnancy loss and an increased risk of multiple congenital malformations in multiple organ systems (see human data) . oral administration of mycophenolate to rats and rabbits during the period of organogenesis produced congenital malformations and pregnancy loss at doses less than the recommended clinical dose (0.05 and 1.1 times exposure at the recommended clinical doses in kidney transplant patients for rats and rabbits, respectively) (see animal data). risks and benefits of mycophenolic acid delayed-release tablets should be discussed with the patient. when appropriate, consider alternative immunosuppressants with less potential for embryo-fetal toxicity. the estimated background risk of pregnancy loss and congenital malformations in organ transplant populations is not clear. in the u.s. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. data human data a spectrum of congenital malformations (including multiple malformations in individual newborns) has been reported in 23% to 27% of live births in mmf exposed pregnancies, based on published data from pregnancy registries. malformations that have been documented include external ear, eye, and other facial abnormalities, including cleft lip and palate, and anomalies of the distal limbs, heart, esophagus, kidney, and nervous system. based on published data from pregnancy registries, the risk of first trimester pregnancy loss has been reported at 45% to 49% following mmf exposure. animal data in animal reproductive toxicology studies, congenital malformations and pregnancy loss occurred when pregnant rats and rabbits received mycophenolate at dose multiples equivalent to and less than the recommended human dose. oral administration of mycophenolate sodium to pregnant rats from gestational day 7 to day 16 at a dose as low as 1 mg per kg resulted in malformations including anophthalmia, exencephaly, and umbilical hernia. the systemic exposure at this dose represents 0.05 times the clinical exposure at the human dose of 1,440 mg per day mycophenolic acid delayed-release tablets. oral administration of mycophenolate to pregnant rabbits from gestational day 7 to day 19 resulted in embryo-fetal lethality and malformations, including ectopia cordis, ectopic kidneys, diaphragmatic hernia, and umbilical hernia at doses equal to or greater than 80 mg per kg per day, in the absence of maternal toxicity. this corresponds to about 1.1 times the recommended clinical dose based on bsa. risk summary there are no data on the presence of mycophenolate in human milk, or the effects on milk production. there are limited data in the national transplantation pregnancy registry on the effects of mycophenolate on a breastfed child (see data). studies in rats treated with mmf have shown mycophenolic acid to be present in milk. because available data are limited, it is not possible to exclude potential risks to a breastfeeding infant. the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for mycophenolic acid delayed-release tablets and any potential adverse effects on the breastfed infant from mycophenolic acid or from the underlying maternal condition. because available data are limited, it is not possible to exclude potential risks to a breastfeeding infant. data limited information is available from the national transplantation pregnancy registry. of seven infants reported by the national transplantation pregnancy registry to have been breastfed while the mother was taking mycophenolate, all were born at 34 to 40 weeks gestation and breastfed for up to 14 months. no adverse events were reported. females of reproductive potential must be made aware of the increased risk of first trimester pregnancy loss and congenital malformations and must be counseled regarding pregnancy prevention and planning. pregnancy planning for female patients taking mycophenolic acid delayed-release tablets who are considering pregnancy, consider alternative immunosuppressants with less potential for embryo-fetal toxicity. risks and benefits of mycophenolic acid delayed-release tablets should be discussed with the patient. pregnancy testing to prevent unplanned exposure during pregnancy, females of reproductive potential should have a serum or urine pregnancy test with a sensitivity of at least 25 miu/ml immediately before starting mycophenolic acid delayed-release tablets. another pregnancy test with the same sensitivity should be done 8 to 10 days later. repeat pregnancy tests should be performed during routine follow-up visits. results of all pregnancy tests should be discussed with the patient. in the event of a positive pregnancy test, consider alternative immunosuppressants with less potential for embryo-fetal toxicity whenever possible. contraception female patients females of reproductive potential taking mycophenolic acid delayed-release tablets must receive contraceptive counseling and use acceptable contraception (see table 5 for acceptable contraception methods). patients must use acceptable birth control during entire mycophenolic acid delayed-release tablets therapy, and for 6 weeks after stopping mycophenolic acid delayed-release tablets, unless the patient chooses abstinence (she chooses to avoid heterosexual intercourse completely). patients should be aware that mycophenolic acid delayed-release tablets reduces blood levels of the hormones in the oral contraceptive pill and could theoretically reduce its effectiveness [see patient counseling information (17), drug interactions (7.8)]. pick from the following birth control options: option 1 methods to use alone intrauterine devices (iuds) tubal sterilization patient’s partner had a vasectomy or option 2 hormone methods choose 1 barrier methods choose 1 choose one hormone method and one barrier method estrogen and progesterone oral contraceptive pill transdermal patch vaginal ring progesterone-only injection implant and diaphragm with spermicide cervical cap with spermicide contraceptive sponge male condom female condom or option 3 barrier methods choose 1 barrier methods choose 1 choose one barrier method from each column (must choose two methods) diaphragm with spermicide cervical cap with spermicide contraceptive sponge and male condom female condom male patients genotoxic effects have been observed in animal studies at exposures exceeding the human therapeutic exposures by approximately 2.5 times. thus, the risk of genotoxic effects on sperm cells cannot be excluded. based on this potential risk, sexually active male patients and/or their female partners are recommended to use effective contraception during treatment of the male patient and for at least 90 days after cessation of treatment. also, based on the potential risk of genotoxic effects, male patients should not donate sperm during treatment with mycophenolic acid delayed-release tablets and for at least 90 days after cessation of treatment [see use in specific populations (8.1), nonclinical toxicology (13.1), patient counseling information (17)]. the safety and effectiveness of mycophenolic acid delayed-release tablets have been established in pediatric kidney transplant patients 5 to 16 years of age who were initiated on mycophenolic acid delayed-release tablets at least 6 months post-transplant. use of mycophenolic acid delayed-release tablets in this age group is supported by evidence from adequate and well-controlled studies of mycophenolic acid delayed-release tablets in a similar population of adult kidney transplant patients with additional pharmacokinetic data in pediatric kidney transplant patients [see dosage and administration (2.2, 2.3) , clinical pharmacology (12.3)] . pediatric doses for patients with bsa < 1.19 m 2 cannot be accurately administered using currently available formulations of mycophenolic acid delayed-release tablets. the safety and effectiveness of mycophenolic acid delayed-release tablets in de novo pediatric kidney transplant patients and in pediatric kidney transplant patients below the age of 5 years have not been established. clinical studies of mycophenolic acid delayed-release tablets did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. of the 372 patients treated with mycophenolic acid delayed-release tablets in the clinical trials, 6%(n = 21) were 65 years of age and older and 0.3% (n = 1) were 75 years of age and older. other reported clinical experience has not identified differences in responses between the elderly and younger patients. in general, dose selection for an elderly patient should be cautious, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

american health packaging - divalproex sodium (unii: 644vl95ao6) (valproic acid - unii:614oi1z5wi) - valproic acid 125 mg - divalproex sodium delayed-release capsules are indicated as monotherapy and adjunctive therapy in the treatment of adult patients and pediatric patients down to the age of 10 years with complex partial seizures that occur either in isolation or in association with other types of seizures. divalproex sodium delayed-release capsules are also indicated for use as sole and adjunctive therapy in the treatment of simple and complex absence seizures, and adjunctively in patients with multiple seizure types that include absence seizures. simple absence is defined as very brief clouding of the sensorium or loss of consciousness accompanied by certain generalized epileptic discharges without other detectable clinical signs. complex absence is the term used when other signs are also present. because of the risk to the fetus of decreased iq, neurodevelopmental disorders, neural tube defects, and other major congenital malformations, which may occur very early in pregnancy, valproate should not be used to treat women with epilepsy or bipolar disorder who are pregnant or who plan to become pregnant unless other medications have failed to provide adequate symptom control or are otherwise unacceptable. valproate should not be administered to a woman of childbearing potential unless other medications have failed to provide adequate symptom control or are otherwise unacceptable [see warnings and precautions (5.2, 5.3, 5.4), use in specific populations (8.1), and patient counseling information (17)]. for prophylaxis of migraine headaches, valproate is contraindicated in women who are pregnant and in women of childbearing potential who are not using effective contraception [see contraindications (4)]. - divalproex sodium delayed-release capsules should not be administered to patients with hepatic disease or significant hepatic dysfunction [see warnings and precautions (5.1)]. - divalproex sodium delayed-release capsules are contraindicated in patients known to have mitochondrial disorders caused by mutations in mitochondrial dna polymerase γ (polg; e.g., alpers-huttenlocher syndrome) and children under two years of age who are suspected of having a polg-related disorder [see warnings and precautions (5.1)]. - divalproex sodium delayed-release capsules are contraindicated in patients with known hypersensitivity to the drug [see warnings and precautions (5.12)]. - divalproex sodium delayed-release capsules are contraindicated in patients with known urea cycle disorders [see warnings and precautions (5.6)]. - for use in prophylaxis of migraine headaches: divalproex sodium delayed-release capsules are contraindicated in women who are pregnant and in women of childbearing potential who are not using effective contraception [see warnings and precautions (5.2, 5.3, 5.4) and use in specific populations (8.1)]. pregnancy exposure registry there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antiepileptic drugs (aeds), including divalproex sodium delayed-release capsules, during pregnancy. encourage women who are taking divalproex sodium delayed-release capsules during pregnancy to enroll in the north american antiepileptic drug (naaed) pregnancy registry by calling toll-free 1-888-233-2334 or visiting the website, http://www.aedpregnancyregistry.org/. this must be done by the patient herself. risk summary for use in prophylaxis of migraine headaches, valproate is contraindicated in women who are pregnant and in women of childbearing potential who are not using effective contraception [see contraindications (4)]. for use in epilepsy or bipolar disorder, valproate should not be used to treat women who are pregnant or who plan to become pregnant unless other medications have failed to provide adequate symptom control or are otherwise unacceptable [see boxed warning and warnings and precautions (5.2, 5.3)]. women with epilepsy who become pregnant while taking valproate should not discontinue valproate abruptly, as this can precipitate status epilepticus with resulting maternal and fetal hypoxia and threat to life. maternal valproate use during pregnancy for any indication increases the risk of congenital malformations, particularly neural tube defects including spina bifida, but also malformations involving other body systems (e.g., craniofacial defects including oral clefts, cardiovascular malformations, hypospadias, limb malformations). this risk is dose-dependent; however, a threshold dose below which no risk exists cannot be established. in utero exposure to valproate may also result in hearing impairment or hearing loss. valproate polytherapy with other aeds has been associated with an increased frequency of congenital malformations compared with aed monotherapy. the risk of major structural abnormalities is greatest during the first trimester; however, other serious developmental effects can occur with valproate use throughout pregnancy. the rate of congenital malformations among babies born to epileptic mothers who used valproate during pregnancy has been shown to be about four times higher than the rate among babies born to epileptic mothers who used other anti-seizure monotherapies [see warnings and precautions (5.2) and data (human)]. epidemiological studies have indicated that children exposed to valproate in utero have lower iq scores and a higher risk of neurodevelopmental disorders compared to children exposed to either another aed in utero or to no aeds in utero [see warnings and precautions (5.3) and data (human)]. an observational study has suggested that exposure to valproate products during pregnancy increases the risk of autism spectrum disorders [see data (human)]. in animal studies, valproate administration during pregnancy resulted in fetal structural malformations similar to those seen in humans and neurobehavioral deficits in the offspring at clinically relevant doses [see data (animal)]. there have been reports of hypoglycemia in neonates and fatal cases of hepatic failure in infants following maternal use of valproate during pregnancy. pregnant women taking valproate may develop hepatic failure or clotting abnormalities including thrombocytopenia, hypofibrinogenemia, and/or decrease in other coagulation factors, which may result in hemorrhagic complications in the neonate including death [see warnings and precautions (5.1, 5.8)]. available prenatal diagnostic testing to detect neural tube and other defects should be offered to pregnant women using valproate. evidence suggests that folic acid supplementation prior to conception and during the first trimester of pregnancy decreases the risk for congenital neural tube defects in the general population. it is not known whether the risk of neural tube defects or decreased iq in the offspring of women receiving valproate is reduced by folic acid supplementation. dietary folic acid supplementation both prior to conception and during pregnancy should be routinely recommended for patients using valproate [see warnings and precautions (5.2, 5.4)]. all pregnancies have a background risk of birth defect, loss, or other adverse outcomes. in the u.s. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. clinical considerations disease-associated maternal and/or embryo/fetal risk to prevent major seizures, women with epilepsy should not discontinue valproate abruptly, as this can precipitate status epilepticus with resulting maternal and fetal hypoxia and threat to life. even minor seizures may pose some hazard to the developing embryo or fetus [see warnings and precautions (5.4)]. however, discontinuation of the drug may be considered prior to and during pregnancy in individual cases if the seizure disorder severity and frequency do not pose a serious threat to the patient. maternal adverse reactions pregnant women taking valproate may develop clotting abnormalities including thrombocytopenia, hypofibrinogenemia, and/or decrease in other coagulation factors, which may result in hemorrhagic complications in the neonate including death [see warnings and precautions (5.8)]. if valproate is used in pregnancy, the clotting parameters should be monitored carefully in the mother. if abnormal in the mother, then these parameters should also be monitored in the neonate. patients taking valproate may develop hepatic failure [see boxed warning and warnings and precautions (5.1)]. fatal cases of hepatic failure in infants exposed to valproate in utero have also been reported following maternal use of valproate during pregnancy. hypoglycemia has been reported in neonates whose mothers have taken valproate during pregnancy. data human neural tube defects and other structural abnormalities there is an extensive body of evidence demonstrating that exposure to valproate in utero increases the risk of neural tube defects and other structural abnormalities. based on published data from the cdc’s national birth defects prevention network, the risk of spina bifida in the general population is about 0.06 to 0.07% (6 to 7 in 10,000 births) compared to the risk following in utero valproate exposure estimated to be approximately 1 to 2% (100 to 200 in 10,000 births). the naaed pregnancy registry has reported a major malformation rate of 9 to 11% in the offspring of women exposed to an average of 1,000 mg/day of valproate monotherapy during pregnancy. these data show an up to a five-fold increased risk for any major malformation following valproate exposure in utero compared to the risk following exposure in utero to other aeds taken as monotherapy. the major congenital malformations included cases of neural tube defects, cardiovascular malformations, craniofacial defects (e.g., oral clefts, craniosynostosis), hypospadias, limb malformations (e.g., clubfoot, polydactyly), and other malformations of varying severity involving other body systems [see warnings and precautions (5.2)]. effect on iq and neurodevelopmental effects published epidemiological studies have indicated that children exposed to valproate in utero have lower iq scores than children exposed to either another aed in utero or to no aeds in utero . the largest of these studies1 is a prospective cohort study conducted in the united states and united kingdom that found that children with prenatal exposure to valproate (n=62) had lower iq scores at age 6 (97 [95% c.i. 94 to 101]) than children with prenatal exposure to the other anti-epileptic drug monotherapy treatments evaluated: lamotrigine (108 [95% c.i. 105 to 110]), carbamazepine (105 [95% c.i. 102 to 108]) and phenytoin (108 [95% c.i. 104 to 112]). it is not known when during pregnancy cognitive effects in valproate-exposed children occur. because the women in this study were exposed to aeds throughout pregnancy, whether the risk for decreased iq was related to a particular time period during pregnancy could not be assessed [see warnings and precautions (5.3)]. although the available studies have methodological limitations, the weight of the evidence supports a causal association between valproate exposure in utero and subsequent adverse effects on neurodevelopment, including increases in autism spectrum disorders and attention deficit/hyperactivity disorder (adhd). an observational study has suggested that exposure to valproate products during pregnancy increases the risk of autism spectrum disorders. in this study, children born to mothers who had used valproate products during pregnancy had 2.9 times the risk (95% confidence interval [ci]: 1.7 to 4.9) of developing autism spectrum disorders compared to children born to mothers not exposed to valproate products during pregnancy. the absolute risks for autism spectrum disorders were 4.4% (95% ci: 2.6% to 7.5%) in valproate-exposed children and 1.5% (95% ci: 1.5% to 1.6%) in children not exposed to valproate products. another observational study found that children who were exposed to valproate in utero had an increased risk of adhd (adjusted hr 1.48; 95% ci, 1.09 to 2.00) compared with the unexposed children. because these studies were observational in nature, conclusions regarding a causal association between in utero valproate exposure and an increased risk of autism spectrum disorder and adhd cannot be considered definitive. other there are published case reports of fatal hepatic failure in offspring of women who used valproate during pregnancy. animal in developmental toxicity studies conducted in mice, rats, rabbits, and monkeys, increased rates of fetal structural abnormalities, intrauterine growth retardation, and embryo-fetal death occurred following administration of valproate to pregnant animals during organogenesis at clinically relevant doses (calculated on a body surface area [mg/m 2 ] basis). valproate induced malformations of multiple organ systems, including skeletal, cardiac, and urogenital defects. in mice, in addition to other malformations, fetal neural tube defects have been reported following valproate administration during critical periods of organogenesis, and the teratogenic response correlated with peak maternal drug levels. behavioral abnormalities (including cognitive, locomotor, and social interaction deficits) and brain histopathological changes have also been reported in mice and rat offspring exposed prenatally to clinically relevant doses of valproate. risk summary valproate is excreted in human milk. data in the published literature describe the presence of valproate in human milk (range: 0.4 mcg/ml to 3.9 mcg/ml), corresponding to 1% to 10% of maternal serum levels. valproate serum concentrations collected from breastfed infants aged 3 days postnatal to 12 weeks following delivery ranged from 0.7 mcg/ml to 4 mcg/ml, which were 1% to 6% of maternal serum valproate levels. a published study in children up to six years of age did not report adverse developmental or cognitive effects following exposure to valproate via breast milk [see data (human)]. there are no data to assess the effects of divalproex sodium on milk production or excretion. clinical considerations the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for divalproex sodium and any potential adverse effects on the breastfed infant from divalproex sodium or from the underlying maternal condition. monitor the breastfed infant for signs of liver damage including jaundice and unusual bruising or bleeding. there have been reports of hepatic failure and clotting abnormalities in offspring of women who used valproate during pregnancy [see use in specific populations (8.1)]. data human in a published study, breast milk and maternal blood samples were obtained from 11 epilepsy patients taking valproate at doses ranging from 300 mg/day to 2,400 mg/day on postnatal days 3 to 6. in 4 patients who were taking valproate only, breast milk contained an average valproate concentration of 1.8 mcg/ml (range: 1.1 mcg/ml to 2.2 mcg/ml), which corresponded to 4.8% of the maternal plasma concentration (range: 2.7% to 7.4%). across all patients (7 of whom were taking other aeds concomitantly), similar results were obtained for breast milk concentration (1.8 mcg/ml, range: 0.4 mcg/ml to 3.9 mcg/ml) and maternal plasma ratio (5.1%, range: 1.3% to 9.6%). a published study of 6 breastfeeding mother-infant pairs measured serum valproate levels during maternal treatment for bipolar disorder (750 mg/day or 1,000 mg/day). none of the mothers received valproate during pregnancy, and infants were aged from 4 weeks to 19 weeks at the time of evaluation. infant serum levels ranged from 0.7 mcg/ml to 1.5 mcg/ml. with maternal serum valproate levels near or within the therapeutic range, infant exposure was 0.9% to 2.3% of maternal levels. similarly, in 2 published case reports with maternal doses of 500 mg/day or 750 mg/day during breastfeeding of infants aged 3 months and 1 month, infant exposure was 1.5% and 6% that of the mother, respectively. a prospective observational multicenter study evaluated the long-term neurodevelopmental effects of aed use on children. pregnant women receiving monotherapy for epilepsy were enrolled with assessments of their children at ages 3 years and 6 years. mothers continued aed therapy during the breastfeeding period. adjusted iqs measured at 3 years for breastfed and non-breastfed children were 93 (n=11) and 90 (n=24), respectively. at 6 years, the scores for breastfed and non-breastfed children were 106 (n=11) and 94 (n=25), respectively (p=0.04). for other cognitive domains evaluated at 6 years, no adverse cognitive effects of continued exposure to an aed (including valproate) via breast milk were observed. contraception women of childbearing potential should use effective contraception while taking valproate [see boxed warning, warnings and precautions (5.4), drug interactions (7), and use in specific populations (8.1)]. this is especially important when valproate use is considered for a condition not usually associated with permanent injury or death such as prophylaxis of migraine headaches [see contraindications (4)]. infertility there have been reports of male infertility coincident with valproate therapy [see adverse reactions (6.2)]. in animal studies, oral administration of valproate at clinically relevant doses resulted in adverse reproductive effects in males [see nonclinical toxicology (13.1)]. experience has indicated that pediatric patients under the age of two years are at a considerably increased risk of developing fatal hepatotoxicity, especially those with the aforementioned conditions [see boxed warning and warnings and precautions (5.1)]. when divalproex sodium delayed-release capsules are used in this patient group, it should be used with extreme caution and as a sole agent. the benefits of therapy should be weighed against the risks. above the age of 2 years, experience in epilepsy has indicated that the incidence of fatal hepatotoxicity decreases considerably in progressively older patient groups. younger children, especially those receiving enzyme inducing drugs, will require larger maintenance doses to attain targeted total and unbound valproate concentrations. pediatric patients (i.e., between 3 months and 10 years) have 50% higher clearances expressed on weight (i.e., ml/min/kg) than do adults. over the age of 10 years, children have pharmacokinetic parameters that approximate those of adults. the variability in free fraction limits the clinical usefulness of monitoring total serum valproic acid concentrations. interpretation of valproic acid concentrations in children should include consideration of factors that affect hepatic metabolism and protein binding. pediatric clinical trials divalproex sodium was studied in seven pediatric clinical trials. two of the pediatric studies were double-blinded placebo-controlled trials to evaluate the efficacy of divalproex sodium extended-release tablets for the indications of mania (150 patients aged 10 to 17 years, 76 of whom were on divalproex sodium extended-release tablets) and migraine (304 patients aged 12 to 17 years, 231 of whom were on divalproex sodium extended-release tablets). efficacy was not established for either the treatment of migraine or the treatment of mania. the most common drug-related adverse reactions (reported > 5% and twice the rate of placebo) reported in the controlled pediatric mania study were nausea, upper abdominal pain, somnolence, increased ammonia, gastritis and rash. the remaining five trials were long term safety studies. two six-month pediatric studies were conducted to evaluate the long-term safety of divalproex sodium extended-release tablets for the indication of mania (292 patients aged 10 to 17 years). two twelve-month pediatric studies were conducted to evaluate the long-term safety of divalproex sodium extended-release tablets for the indication of migraine (353 patients aged 12 to 17 years). one twelve-month study was conducted to evaluate the safety of divalproex sodium delayed-release capsules in the indication of partial seizures (169 patients aged 3 to 10 years). in these seven clinical trials, the safety and tolerability of divalproex sodium in pediatric patients were shown to be comparable to those in adults [see adverse reactions (6)]. juvenile animal toxicology in studies of valproate in immature animals, toxic effects not observed in adult animals included retinal dysplasia in rats treated during the neonatal period (from postnatal day 4) and nephrotoxicity in rats treated during the neonatal and juvenile (from postnatal day 14) periods. the no-effect dose for these findings was less than the maximum recommended human dose on a mg/m 2 basis. no patients above the age of 65 years were enrolled in double-blind prospective clinical trials of mania associated with bipolar illness. in a case review study of 583 patients, 72 patients (12%) were greater than 65 years of age. a higher percentage of patients above 65 years of age reported accidental injury, infection, pain, somnolence, and tremor. discontinuation of valproate was occasionally associated with the latter two events. it is not clear whether these events indicate additional risk or whether they result from preexisting medical illness and concomitant medication use among these patients. a study of elderly patients with dementia revealed drug related somnolence and discontinuation for somnolence [see warnings and precautions (5.14)]. the starting dose should be reduced in these patients, and dosage reductions or discontinuation should be considered in patients with excessive somnolence [see dosage and administration (2.2)]. the capacity of elderly patients (age range: 68 to 89 years) to eliminate valproate has been shown to be reduced compared to younger adults (age range: 22 to 26 years) [see clinical pharmacology (12.3)]. liver disease liver disease impairs the capacity to eliminate valproate.

american health packaging - febuxostat (unii: 101v0r1n2e) (febuxostat - unii:101v0r1n2e) - febuxostat tablets are xanthine oxidase (xo) inhibitor indicated for the chronic management of hyperuricemia in adult patients with gout who have an inadequate response to a maximally titrated dose of allopurinol, who are intolerant to allopurinol, or for whom treatment with allopurinol is not advisable. limitations of use: febuxostat tablets are not recommended for the treatment of asymptomatic hyperuricemia. febuxostat tablets are contraindicated in patients being treated with azathioprine or mercaptopurine [see drug interactions (7)]. risk summary limited available data with febuxostat use in pregnant women are insufficient to inform a drug associated risk of adverse developmental outcomes. no adverse developmental effects were observed in embryo-fetal development studies with oral administration of febuxostat to pregnant rats and rabbits during organogenesis at doses that produced maternal exposures up to 40 and 51 times, respectively, the exposure at the maximum recommended human dose (mrhd). no adverse developmental effects were observed in a pre-and postnatal development study with administration of febuxostat to pregnant rats from organogenesis through lactation at an exposure approximately 11 times the mrhd (see data) . the estimated background risk of major birth defects and miscarriage for the indicated population is unknown. all pregnancies have a background risk of birth defect, loss, or other adverse outcomes. in the us general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. data animal data in an embryo-fetal development study in pregnant rats dosed during the period of organogenesis from gestation days 7 to 17, febuxostat was not teratogenic and did not affect fetal development or survival at exposures up to approximately 40 times the mrhd (on an auc basis at maternal oral doses up to 48 mg/kg/day). in an embryo-fetal development study in pregnant rabbits dosed during the period of organogenesis from gestation days 6 to 18, febuxostat was not teratogenic and did not affect fetal development at exposures up to approximately 51 times the mrhd (on an auc basis at maternal oral doses up to 48 mg/kg/day). in a pre-and postnatal development study in pregnant female rats dosed orally from gestation day 7 through lactation day 20, febuxostat had no effects on delivery or growth and development of offspring at a dose approximately 11 times the mrhd (on an auc basis at a maternal oral dose of 12 mg/kg/day). however, increased neonatal mortality and a reduction in neonatal body weight gain were observed in the presence of maternal toxicity at a dose approximately 40 times the mrhd (on an auc basis at a maternal oral dose of 48 mg/kg/day). febuxostat crossed the placental barrier following oral administration to pregnant rats and was detected in fetal tissues. risk summary there are no data on the presence of febuxostat in human milk, the effects on the breastfed infant, or the effects on milk production. febuxostat is present in rat milk. the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for febuxostat and any potential adverse effects on the breastfed child from febuxostat or from the underlying maternal condition. data animal data orally administered febuxostat was detected in the milk of lactating rats at up to approximately 7 times the plasma concentration. safety and effectiveness of febuxostat in pediatric patients have not been established. no dose adjustment is necessary in elderly patients. of the total number of patients in studies 1, 2, and 3 (clinical studies of febuxostat in the treatment of gout) [see clinical studies (14.1)], 16% were 65 and over, while 4% were 75 and over. comparing patients in different age groups, no clinically significant differences in safety or effectiveness were observed but greater sensitivity of some older individuals cannot be ruled out. the c max and auc 24 of febuxostat following multiple oral doses of febuxostat in geriatric patients (≥65 years) were similar to those in younger patients (18 to 40 years) [see clinical pharmacology (12.3)]. no dose adjustment is necessary in patients with mild to moderate renal impairment (cl cr 30 to 89 ml/min). for patients with severe renal impairment (cl cr 15 to 29 ml/min), the recommended dosage of febuxostat is limited to 40 mg once daily [see dosage and administration (2.2) and clinical pharmacology (12.3)]. no dose adjustment is necessary in patients with mild or moderate hepatic impairment (child-pugh class a or b). no studies have been conducted in patients with severe hepatic impairment (child-pugh class c); therefore, caution should be exercised in these patients [see clinical pharmacology (12.3)]. no studies have been conducted in patients with secondary hyperuricemia (including organ transplant recipients); febuxostat is not recommended for use in patients whom the rate of urate formation is greatly increased (e.g., malignant disease and its treatment, lesch-nyhan syndrome). the concentration of xanthine in urine could, in rare cases, rise sufficiently to allow deposition in the urinary tract.
