pai holdings, llc dba pharmaceutical associates, inc. and dba pai pharma - buprenorphine hydrochloride (unii: 56w8mw3en1) (buprenorphine - unii:40d3scr4gz) - buprenorphine sublingual tablets is indicated for the treatment of opioid dependence and is preferred for induction. buprenorphine sublingual tablets should be used as part of a complete treatment plan to include counseling and psychosocial support. buprenorphine sublingual tablets is contraindicated in patients with a history of hypersensitivity to buprenorphine, as serious adverse reactions, including anaphylactic shock, have been reported [see warnings and precautions (5.9)] . risk summary the data on use of buprenorphine, the active ingredient in buprenorphine sublingual tablets, in pregnancy, are limited; however, these data do not indicate an increased risk of major malformations specifically due to buprenorphine exposure. there are limited data from randomized clinical trials in women maintained on buprenorphine that were not designed appropriately to assess the risk of major malformations [see data] . observational studies have reported on congenital malformations among buprenorphine-exposed pregnancies but were also not designed appropriately to assess the risk of congenital malformations specifically due to buprenorphine exposure [see data] . reproductive and developmental studies in rats and rabbits identified adverse events at clinically relevant and higher doses. embryofetal death was observed in both rats and rabbits administered buprenorphine during the period of organogenesis at doses approximately 6 and 0.3 times, respectively, the human sublingual dose of 16 mg/day of buprenorphine. pre- and post-natal development studies in rats demonstrated increased neonatal deaths at 0.3 times and above and dystocia at approximately 3 times the human sublingual dose of 16 mg/day of buprenorphine. no clear teratogenic effects were seen when buprenorphine was administered during organogenesis with a range of doses equivalent to or greater than the human sublingual dose of 16 mg/day of buprenorphine. however, increases in skeletal abnormalities were noted in rats and rabbits administered buprenorphine daily during organogenesis at doses approximately 0.6 times and approximately equal to the human sublingual dose of 16 mg/day of buprenorphine, respectively. in a few studies, some events such as acephalus and omphalocele were also observed but these findings were not clearly treatment-related [see data]. based on animal data, advice pregnant women of the potential risk to a fetus. the estimated background risks of major birth defects and miscarriage for the indicated population are 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 2-4% and 15-20%, respectively. clinical considerations disease-associated maternal and embryo-fetal risk untreated opioid addiction in pregnancy is associated with adverse obstetrical outcomes such as low birth weight, preterm birth, and fetal death. in addition, untreated opioid addiction often results in continued or relapsing illicit opioid use. dose adjustment during pregnancy and the postpartum period dosage adjustments of buprenorphine may be required during pregnancy, even if the patient was maintained on a stable dose prior to pregnancy. withdrawal signs and symptoms should be monitored closely, and the dose adjusted as necessary. fetal/neonatal adverse reactions neonatal opioid withdrawal syndrome may occur in newborn infants of mothers who are receiving treatment with buprenorphine sublingual tablets. neonatal opioid withdrawal syndrome presents as irritability, hyperactivity and abnormal sleep pattern, high pitched cry, tremor, vomiting, diarrhea, and/or failure to gain weight. signs of neonatal withdrawal usually occur in the first days after birth. the duration and severity of neonatal opioid withdrawal syndrome may vary. observe newborns for signs of neonatal opioid withdrawal syndrome and manage accordingly. [see warnings and precautions (5.5)] . labor or delivery opioid-dependent women on buprenorphine maintenance therapy may require additional analgesia during labor. data human data studies have been conducted to evaluate neonatal outcomes in women exposed to buprenorphine during pregnancy. limited data from trials, observational studies, case series, and case reports on buprenorphine use in pregnancy do not indicate an increased risk of major malformations specifically due to buprenorphine. several factors may complicate the interpretation of investigations of the children of women who take buprenorphine during pregnancy, including maternal use of illicit drugs, late presentation for prenatal care, infection, poor compliance, poor nutrition, and psychosocial circumstances. interpretation of data is complicated further by the lack of information on untreated opioid-dependent pregnant women, who would be the most appropriate group for comparison. rather, women on another form of opioid medication-assisted treatment, or women in the general population are generally used as the comparison group. however, women in these comparison groups may be different from women prescribed buprenorphine-containing products with respect to maternal factors that may lead to poor pregnancy outcomes. in a multicenter, double-blind, randomized, controlled trial [maternal opioid treatment: human experimental research (mother)] designed primarily to assess neonatal opioid withdrawal effects, opioid-dependent pregnant women were randomized to buprenorphine (n=86) or methadone (n=89) treatment, with enrollment at an average gestational age of 18.7 weeks in both groups. a total of 28 of the 86 women in the buprenorphine group (33%) and 16 of the 89 women in the methadone group (18%) discontinued treatment before the end of pregnancy. among women who remained in treatment until delivery, there was no difference between buprenorphine-treated and methadone-treated groups in the number of neonates requiring nows treatment or in the peak severity of nows. buprenorphine-exposed neonates required less morphine (mean total dose, 1.1 mg vs. 10.4 mg), had shorter hospital stays (10.0 days vs. 17.5 days), and shorter duration of treatment for nows (4.1 days vs. 9.9 days) compared to the methadone-exposed group. there were no differences between groups in other primary outcomes (neonatal head circumference,) or secondary outcomes (weight and length at birth, preterm birth, gestational age at delivery, and 1- minute and 5-minute apgar scores), or in the rates of maternal or neonatal adverse events. the outcomes among mothers who discontinued treatment before delivery and may have relapsed to illicit opioid use are not known. because of the imbalance in discontinuation rates between the buprenorphine and methadone groups, the study findings are difficult to interpret. animal data the exposure margins listed below are based on body surface area comparisons (mg/m2) to the human sublingual dose of 16 mg buprenorphine via buprenorphine sublingual tablets. no definitive drug-related teratogenic effects were observed in rats and rabbits at im doses up to 30 mg/kg/day (estimated exposure approximately 20 times and 35 times, respectively, the human sublingual dose of 16 mg). maternal toxicity resulting in mortality was noted in these studies in both rats and rabbits. acephalus was observed in one rabbit fetus from the low-dose group and omphalocele was observed in two rabbit fetuses from the same litter in the mid-dose group; no findings were observed in fetuses from the high-dose group. maternal toxicity was seen in the high-dose group but not at the lower doses where the findings were observed. following oral administration of buprenorphine to rats, dose-related post-implantation losses, evidenced by increases in the numbers of early resorptions with consequent reductions in the numbers of fetuses, were observed at doses of 10 mg/kg/day or greater (estimated exposure approximately 6 times the human sublingual dose of 16 mg). in the rabbit, increased post-implantation losses occurred at an oral dose of 40 mg/kg/day. following im administration in the rat and the rabbit, post-implantation losses, as evidenced by decreases in live fetuses and increases in resorptions, occurred at 30 mg/kg/day. buprenorphine was not teratogenic in rats or rabbits after im or subcutaneous (sc) doses up to 5 mg/kg/day (estimated exposure was approximately 3 and 6 times, respectively, the human sublingual dose of 16 mg), after iv doses up to 0.8 mg/kg/day (estimated exposure was approximately 0.5 times and equal to, respectively, the human sublingual dose of 16 mg), or after oral doses up to 160 mg/kg/day in rats (estimated exposure was approximately 95 times the human sublingual dose of 16 mg) and 25 mg/kg/day in rabbits (estimated exposure was approximately 30 times the human sublingual dose of 16 mg). significant increases in skeletal abnormalities (e.g., extra thoracic vertebra or thoraco-lumbar ribs) were noted in rats after sc administration of 1 mg/kg/day and up (estimated exposure was approximately 0.6 times the human sublingual dose of 16 mg), but were not observed at oral doses up to 160 mg/kg/day. increases in skeletal abnormalities in rabbits after im administration of 5 mg/kg/day (estimated exposure was approximately 6 times the human sublingual dose of 16 mg) in the absence of maternal toxicity or oral administration of 1 mg/kg/day or greater (estimated exposure was approximately equal to the human sublingual dose of 16 mg) were not statistically significant. in rabbits, buprenorphine produced statistically significant pre-implantation losses at oral doses of 1 mg/kg/day or greater and post- implantation losses that were statistically significant at iv doses of 0.2 mg/kg/day or greater (estimated exposure approximately 0.3 times the human sublingual dose of 16 mg). no maternal toxicity was noted at doses causing post-implantation loss in this study. dystocia was noted in pregnant rats treated intramuscularly with buprenorphine from gestation day 14 through lactation day 21 at 5 mg/kg/day (approximately 3 times the human sublingual dose of 16 mg). fertility, and pre- and post-natal development studies with buprenorphine in rats indicated increases in neonatal mortality after oral doses of 0.8 mg/kg/day and up (approximately 0.5 times the human sublingual dose of 16 mg), after im doses of 0.5 mg/kg/day and up (approximately 0.3 times the human sublingual dose of 16 mg), and after sc doses of 0.1 mg/kg/day and up (approximately 0.06 times the human sublingual dose of 16 mg). an apparent lack of milk production during these studies likely contributed to the decreased pup viability and lactation indices. delays in the occurrence of righting reflex and startle response were noted in rat pups at an oral dose of 80 mg/kg/day (approximately 50 times the human sublingual dose of 16 mg). risk summary based on two studies in 13 lactating women maintained on buprenorphine treatment, buprenorphine and its metabolite norbuprenorphine were present in low levels in human milk, and available data have not shown adverse reactions in breastfed infants. the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for buprenorphine and any potential adverse effects on the breastfed child from the drug or from the underlying maternal condition. clinical considerations advise breastfeeding women taking buprenorphine products to monitor the infant for increased drowsiness and breathing difficulties. data data were consistent from two studies (n=13) of breastfeeding infants whose mothers were maintained on sublingual doses of buprenorphine ranging from 2.4 to 24 mg/day, showing that the infants were exposed to less than 1% of the maternal daily dose. in a study of six lactating women who were taking a median sublingual buprenorphine dose of 0.29 mg/kg/day 5 to 8 days after delivery, breast milk provided a median infant dose of 0.42 mcg/kg/day of buprenorphine and 0.33 mcg/kg/day of norbuprenorphine, equal to 0.2% and 0.12%, respectively, of the maternal weight-adjusted dose (relative dose/kg (%) of norbuprenorphine was calculated from the assumption that buprenorphine and norbuprenorphine are equipotent). data from a study of seven lactating women who were taking a median sublingual buprenorphine dose of 7 mg/day an average of 1.12 months after delivery indicated that the mean milk concentrations (cavg ) of buprenorphine and norbuprenorphine were 3.65 mcg/l and 1.94 mcg/l respectively. based on the study data, and assuming milk consumption of 150 ml/kg/day, an exclusively breastfed infant would receive an estimated mean absolute infant dose (aid) of 0.55 mcg/kg/day of buprenorphine and 0.29 mcg/kg/day of norbuprenorphine, or a mean relative infant dose (rid) of 0.38% and 0.18%, respectively, of the maternal weight-adjusted dose. infertility chronic use of opioids may cause reduced fertility in females and males of reproductive potential. it is not known whether these effects on fertility are reversible [see adverse reactions (6.2), clinical pharmacology (12.2), nonclinical toxicology (13.1)] . the safety and effectiveness of buprenorphine sublingual tablet has not been established in pediatric patients. clinical studies of buprenorphine sublingual tablets, buprenorphine and naloxone sublingual film, or buprenorphine and naloxone sublingual tablet did not include sufficient numbers of subjects aged 65 and over to determine whether they responded differently than younger subjects. other reported clinical experience has not identified differences in responses between the elderly and younger patients. due to possible decreased hepatic, renal, or cardiac function and of concomitant disease or other drug therapy in geriatric patients, the decision to prescribe buprenorphine sublingual tablets should be made cautiously in individuals 65 years of age or older and these patients should be monitored for signs and symptoms of toxicity or overdose. the effects of hepatic impairment on the pharmacokinetics of buprenorphine were evaluated in a pharmacokinetic study.  buprenorphine is extensively metabolized in the liver and buprenorphine plasma levels were found to be higher and the half-life was found to be longer in subjects with moderate and severe hepatic impairment, but not in subjects with mild hepatic impairment. for patients with severe hepatic impairment, a dose adjustment is recommended, and patients with moderate or severe hepatic impairment should be monitored for signs and symptoms of toxicity or overdose caused by increased levels of buprenorphine [see dosage and administration (2.7), warnings and precautions (5.12), clinical pharmacology (12.3)] . no differences in buprenorphine pharmacokinetics were observed between 9 dialysis-dependent and 6 normal patients following iv administration of 0.3 mg buprenorphine. buprenorphine sublingual tablets contains buprenorphine, a schedule iii controlled substance under the controlled substances act. buprenorphine, like morphine and other opioids, has the potential for being abused and is subject to criminal diversion. this should be considered when prescribing or dispensing buprenorphine in situations when the clinician is concerned about an increased risk of misuse, abuse, or diversion. healthcare professionals should contact their state professional licensing board or state controlled substances authority for information on how to prevent and detect abuse or diversion of this product. patients who continue to misuse, abuse, or divert, buprenorphine products or other opioids should be provided or referred for more intensive and structured treatment. abuse of buprenorphine poses a risk of overdose and death. this risk is increased with the abuse of buprenorphine and alcohol and other substances, especially benzodiazepines. the healthcare provider may be able to more easily detect misuse or diversion by maintaining records of medication prescribed including date, dose, quantity, frequency of refills, and renewal requests of medication prescribed. proper assessment of the patient, proper prescribing practices, periodic re-evaluation of therapy, and proper handling and storage of the medication are appropriate measures that help to limit abuse of opioid drugs. buprenorphine is a partial agonist at the mu-opioid receptor and chronic administration produces physical dependence of the opioid type, characterized by moderate withdrawal signs and symptoms upon abrupt discontinuation or rapid taper. the withdrawal syndrome is typically milder than seen with full agonists and may be delayed in onset [see warnings and precautions (5.7)]. neonatal opioid withdrawal syndrome (nows) is an expected and treatable outcome of prolonged use of opioids during pregnancy [see warnings and precautions (5.5)] instructions for use buprenorphine (bue’’ pre nor’ feen) sublingual tablets ciii this “instructions for use” contains information on how to correctly take buprenorphine sublingual tablets. important information you need to know before taking buprenorphine sublingual tablets: - your healthcare provider should show you how to take buprenorphine sublingual tablets the right way. preparing to take buprenorphine sublingual tablets: - put the tablets under your tongue. let them dissolve completely. - while buprenorphine sublingual tablet is dissolving, do not chew or swallow the tablet because the medicine will not work as well. - talking while the tablet is dissolving can affect how well the medicine in buprenorphine sublingual tablet is absorbed. - after buprenorphine sublingual tablets is completely dissolved, rinse your mouth with water and swallow. wait for at least one hour before brushing teeth. - if you miss a dose of buprenorphine sublingual tablets, take your medicine when you remember. if it is almost time for your next dose, skip the missed dose and take the next dose at your regular time. do not take 2 doses at the same time unless your healthcare provider tells you to. if you are not sure about your dosing, call your healthcare provider. - do not stop taking buprenorphine sublingual tablets suddenly. you could become sick and have withdrawal symptoms because your body has become used to the medicine. physical dependence is not the same as drug addiction. your healthcare provider can tell you more about the differences between physical dependence and drug addiction. to have fewer withdrawal symptoms, ask your healthcare provider how to stop using buprenorphine sublingual tablets the right way. if you take too much buprenorphine sublingual tablets or overdose, call poison control or get emergency medical help right away. storing buprenorphine sublingual tablets: - store buprenorphine sublingual tablets at room temperature between 59°f and 86°f (15°c to 30°c). - keep buprenorphine sublingual tablets in a safe place, out of the sight and reach of children. disposing of buprenorphine sublingual tablets: - dispose of unused buprenorphine sublingual tablets as soon as you no longer need them. - dispose of expired, unwanted or unused buprenorphine sublingual tablets by promptly flushing down the toilet (if a drug take‐back option is not readily available). visit www.fda.gov/drugdisposal for additional information on disposal of unused medicines. if you need help with disposal of buprenorphine sublingual tablets, call 1-800-845-8210. this “instructions for use” has been approved by the u.s. food and drug administration.

pai holdings, llc dba pharmaceutical associates, inc. and dba pai pharma - buprenorphine hydrochloride (unii: 56w8mw3en1) (buprenorphine - unii:40d3scr4gz), naloxone hydrochloride (unii: f850569pqr) (naloxone - unii:36b82amq7n) - buprenorphine and naloxone sublingual tablets are indicated for the maintenance treatment of opioid dependence. buprenorphine and naloxone sublingual tablets should be used as part of a complete treatment plan that includes counseling and psychosocial support. buprenorphine and naloxone sublingual tablets are contraindicated in patients with a history of hypersensitivity to buprenorphine or naloxone as serious adverse reactions, including anaphylactic shock, have been reported [see warnings and precautions (5.9)] . risk summary the data on use of buprenorphine, one of the active ingredients in buprenorphine and naloxone sublingual tablets, in pregnancy, are limited; however, these data do not indicate an increased risk of major malformations specifically due to buprenorphine exposure. there are limited data from randomized clinical trials in women maintained on buprenorphine that were not designed appropriately to assess the risk of major malformations [see data]. observational studies have reported on congenital malformations among buprenorphine-exposed pregnancies but were also not designed appropriately to assess the risk of congenital malformations specifically due to buprenorphine exposure [see data]. the extremely limited data on sublingual naloxone exposure in pregnancy are not sufficient to evaluate a drug-associated risk. reproductive and developmental studies in rats and rabbits identified adverse events at clinically relevant and higher doses. embryo-fetal death was observed in both rats and rabbits administered buprenorphine during the period of organogenesis at doses approximately 6 and 0.3 times, respectively, the human sublingual dose of 16 mg/day of buprenorphine. pre- and post-natal development studies in rats demonstrated increased neonatal deaths at 0.3 times and above and dystocia at approximately 3 times the human sublingual dose of 16 mg/day of buprenorphine. no clear teratogenic effects were seen when buprenorphine was administered during organogenesis with a range of doses equivalent to or greater than the human sublingual dose of 16 mg/day of buprenorphine. however, increases in skeletal abnormalities were noted in rats and rabbits administered buprenorphine daily during organogenesis at doses approximately 0.6 times and approximately equal to the human sublingual dose of 16 mg/day of buprenorphine, respectively. in a few studies, some events such as acephalus and omphalocele were also observed but these findings were not clearly treatment-related [see data]. based on animal data, advice pregnant women of the potential risk to a fetus. the estimated background risks of major birth defects and miscarriage for the indicated population are 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 embryo-fetal risk untreated opioid addiction in pregnancy is associated with adverse obstetrical outcomes such as low birth weight, preterm birth, and fetal death. in addition, untreated opioid addiction often results in continued or relapsing illicit opioid use. dose adjustment during pregnancy and the postpartum period dosage adjustments of buprenorphine may be required during pregnancy, even if the patient was maintained on a stable dose prior to pregnancy. withdrawal signs and symptoms should be monitored closely and the dose adjusted as necessary. fetal/neonatal adverse reactions neonatal opioid withdrawal syndrome may occur in newborn infants of mothers who are receiving treatment with buprenorphine and naloxone sublingual tablets. neonatal opioid withdrawal syndrome presents as irritability, hyperactivity and abnormal sleep pattern, high pitched cry, tremor, vomiting, diarrhea and/or failure to gain weight. signs of neonatal withdrawal usually occur in the first days after birth. the duration and severity of neonatal opioid withdrawal syndrome may vary. observe newborns for signs of neonatal opioid withdrawal syndrome and manage accordingly [see warnings and precautions (5.5)] . labor or delivery opioid-dependent women on buprenorphine maintenance therapy may require additional analgesia during labor. data human data studies have been conducted to evaluate neonatal outcomes in women exposed to buprenorphine during pregnancy. limited data from trials, observational studies, case series, and case reports on buprenorphine use in pregnancy do not indicate an increased risk of major malformations specifically due to buprenorphine. several factors may complicate the interpretation of investigations of the children of women who take buprenorphine during pregnancy, including maternal use of illicit drugs, late presentation for prenatal care, infection, poor compliance, poor nutrition, and psychosocial circumstances. interpretation of data is complicated further by the lack of information on untreated opioid-dependent pregnant women, who would be the most appropriate group for comparison. rather, women on another form of opioid medication-assisted treatment, or women in the general population are generally used as the comparison group. however, women in these comparison groups may be different from women prescribed buprenorphine-containing products with respect to maternal factors that may lead to poor pregnancy outcomes. in a multicenter, double-blind, randomized, controlled trial [maternal opioid treatment: human experimental research (mother)] designed primarily to assess neonatal opioid withdrawal effects, opioid-dependent pregnant women were randomized to buprenorphine (n=86) or methadone (n=89) treatment, with enrollment at an average gestational age of 18.7 weeks in both groups. a total of 28 of the 86 women in the buprenorphine group (33%) and 16 of the 89 women in the methadone group (18%) discontinued treatment before the end of pregnancy. among women who remained in treatment until delivery, there was no difference between buprenorphine-treated and methadone-treated groups in the number of neonates requiring nows treatment or in the peak severity of nows. buprenorphine-exposed neonates required less morphine (mean total dose, 1.1 mg vs. 10.4 mg), had shorter hospital stays (10.0 days vs. 17.5 days), and shorter duration of treatment for nows (4.1 days vs. 9.9 days) compared to the methadone-exposed group. there were no differences between groups in other primary outcomes (neonatal head circumference,) or secondary outcomes (weight and length at birth, preterm birth, gestational age at delivery, and 1-minute and 5-minute apgar scores), or in the rates of maternal or neonatal adverse events. the outcomes among mothers who discontinued treatment before delivery and may have relapsed to illicit opioid use are not known. because of the imbalance in discontinuation rates between the buprenorphine and methadone groups, the study findings are difficult to interpret. animal data the exposure margins listed below are based on body surface area comparisons (mg/m 2 ) to the human sublingual dose of 16 mg buprenorphine via buprenorphine and naloxone sublingual tablets. effects on embryo-fetal development were studied in sprague-dawley rats and russian white rabbits following oral (1:1) and intramuscular (im) (3:2) administration of mixtures of buprenorphine and naloxone during the period of organogenesis. following oral administration to rats, no teratogenic effects were observed at buprenorphine doses up to 250 mg/kg/day (estimated exposure approximately 150 times, the human sublingual dose of 16 mg) in the presence of maternal toxicity (mortality). following oral administration to rabbits, no teratogenic effects were observed at buprenorphine doses up to 40 mg/kg/day (estimated exposure approximately 50 times the human sublingual dose of 16 mg) in the absence of clear maternal toxicity. no definitive drug-related teratogenic effects were observed in rats and rabbits at im doses up to 30 mg/kg/day (estimated exposure approximately 20 times and 35 times, respectively, the human sublingual dose of 16 mg). maternal toxicity resulting in mortality was noted in these studies in both rats and rabbits. acephalus was observed in one rabbit fetus from the low-dose group and omphalocele was observed in two rabbit fetuses from the same litter in the mid-dose group; no findings were observed in fetuses from the high-dose group. maternal toxicity was seen in the high -dose group but not at the lower doses where the findings were observed. following oral administration of buprenorphine to rats, dose-related post-implantation losses, evidenced by increases in the numbers of early resorptions with consequent reductions in the numbers of fetuses, were observed at doses of 10 mg/kg/day or greater (estimated exposure approximately 6 times the human sublingual dose of 16 mg). in the rabbit, increased post-implantation losses occurred at an oral dose of 40 mg/kg/day. following im administration in the rat and the rabbit, post-implantation losses, as evidenced by decreases in live fetuses and increases in resorptions, occurred at 30 mg/kg/day. buprenorphine was not teratogenic in rats or rabbits after im or subcutaneous (sc) doses up to 5 mg/kg/day (estimated exposure was approximately 3 and 6 times, respectively, the human sublingual dose of 16 mg), after iv doses up to 0.8 mg/kg/day (estimated exposure was approximately 0.5 times and equal to, respectively, the human sublingual dose of 16 mg), or after oral doses up to 160 mg/kg/day in rats (estimated exposure was approximately 95 times the human sublingual dose of 16 mg) and 25 mg/kg/day in rabbits (estimated exposure was approximately 30 times the human sublingual dose of 16 mg). significant increases in skeletal abnormalities (e.g., extra thoracic vertebra or thoraco-lumbar ribs) were noted in rats after sc administration of 1 mg/kg/day and up (estimated exposure was approximately 0.6 times the human sublingual dose of 16 mg) but were not observed at oral doses up to 160 mg/kg/day. increases in skeletal abnormalities in rabbits after im administration of 5 mg/kg/day (estimated exposure was approximately 6 times the human sublingual dose of 16 mg) in the absence of maternal toxicity or oral administration of 1 mg/kg/day or greater (estimated exposure was approximately equal to the human sublingual dose of 16 mg) were not statistically significant. in rabbits, buprenorphine produced statistically significant pre-implantation losses at oral doses of 1 mg/kg/day or greater and post-implantation losses that were statistically significant at iv doses of 0.2 mg/kg/day or greater (estimated exposure approximately 0.3 times the human sublingual dose of 16 mg). no maternal toxicity was noted at doses causing post-implantation loss in this study. dystocia was noted in pregnant rats treated intramuscularly with buprenorphine from gestation day 14 through lactation day 21 at 5 mg/kg/day (approximately 3 times the human sublingual dose of 16 mg). fertility, and pre-, and postnatal development studies with buprenorphine in rats indicated increases in neonatal mortality after oral doses of 0.8 mg/kg/day and up (approximately 0.5 times the human sublingual dose of 16 mg), after im doses of 0.5 mg/kg/day and up (approximately 0.3 times the human sublingual dose of 16 mg), and after sc doses of 0.1 mg/kg/day and up (approximately 0.06 times the human sublingual dose of 16 mg). an apparent lack of milk production during these studies likely contributed to the decreased pup viability and lactation indices. delays in the occurrence of righting reflex and startle response were noted in rat pups at an oral dose of 80 mg/kg/day (approximately 50 times the human sublingual dose of 16 mg). risk summary based on two studies in 13 lactating women maintained on buprenorphine treatment, buprenorphine and its metabolite norbuprenorphine were present in low levels in human milk, and available data have not shown adverse reactions in breastfed infants. there are no data on the combination product buprenorphine/naloxone in breastfeeding, however oral absorption of naloxone is limited. the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for buprenorphine and naloxone sublingual tablets and any potential adverse effects on the breastfed child from the drug or from the underlying maternal condition. clinical considerations advise breastfeeding women taking buprenorphine products to monitor the infant for increased drowsiness and breathing difficulties. data data were consistent from two studies (n=13) of breastfeeding infants whose mothers were maintained on sublingual doses of buprenorphine ranging from 2.4 to 24 mg/day, showing that the infants were exposed to less than 1% of the maternal daily dose. in a study of six lactating women who were taking a median sublingual buprenorphine dose of 0.29 mg/kg/day 5 to 8 days after delivery, breast milk provided a median infant dose of 0.42 mcg/kg/day of buprenorphine and 0.33 mcg/kg/day of norbuprenorphine, equal to 0.2% and 0.12%, respectively, of the maternal weight-adjusted dose (relative dose/kg (%) of norbuprenorphine was calculated from the assumption that buprenorphine and norbuprenorphine are equipotent). data from a study of seven lactating women who were taking a median sublingual buprenorphine dose of 7 mg/day an average of 1.12 months after delivery indicated that the mean milk concentrations (cavg ) of buprenorphine and norbuprenorphine were 3.65 mcg/l and 1.94 mcg/l respectively. based on the study data, and assuming milk consumption of 150 ml/kg/day, an exclusively breastfed infant would receive an estimated mean absolute infant dose (aid) of 0.55 mcg/kg/day of buprenorphine and 0.29 mcg/kg/day of norbuprenorphine, or a mean relative infant dose (rid) of 0.38% and 0.18%, respectively, of the maternal weight-adjusted dose. infertility chronic use of opioids may cause reduced fertility in females and males of reproductive potential. it is not known whether these effects on fertility are reversible [see adverse reactions (6.2), clinical pharmacology (12.2), nonclinical toxicology (13.1)]. the safety and effectiveness of buprenorphine and naloxone sublingual tablets have not been established in pediatric patients. this product is not appropriate for the treatment of neonatal abstinence syndrome in neonates, because it contains naloxone, an opioid antagonist. clinical studies of buprenorphine and naloxone sublingual tablets, buprenorphine and naloxone sublingual film, or buprenorphine sublingual tablets did not include sufficient numbers of subjects aged 65 and over to determine whether they responded differently than younger subjects. other reported clinical experience has not identified differences in responses between the elderly and younger patients. due to possible decreased hepatic, renal, or cardiac function and of concomitant disease or other drug therapy in geriatric patients, the decision to prescribe buprenorphine and naloxone sublingual tablets should be made cautiously in individuals 65 years of age or older and these patients should be monitored for signs and symptoms of toxicity or overdose. the effect of hepatic impairment on the pharmacokinetics of buprenorphine and naloxone has been evaluated in a pharmacokinetic study. both drugs are extensively metabolized in the liver. while no clinically significant changes have been observed in subjects with mild hepatic impairment; the plasma levels have been shown to be higher and half-life values have been shown to be longer for both buprenorphine and naloxone in subjects with moderate and severe hepatic impairment. the magnitude of the effects on naloxone are greater than that on buprenorphine in both moderately and severely impaired subjects. the difference in magnitude of the effects on naloxone and buprenorphine are greater in subjects with severe hepatic impairment than in subjects with moderate hepatic impairment, and therefore the clinical impact of these effects is likely to be greater in patients with severe hepatic impairment than in patients with moderate hepatic impairment. buprenorphine/naloxone products should be avoided in patients with severe hepatic impairment and may not be appropriate for patients with moderate hepatic impairment [see warnings and precautions (5.12), clinical pharmacology (12.3)]. no differences in buprenorphine pharmacokinetics were observed between 9 dialysis-dependent and 6 normal patients following iv administration of 0.3 mg buprenorphine. the effects of renal failure on naloxone pharmacokinetics are unknown. buprenorphine and naloxone sublingual tablets contain buprenorphine, a schedule iii controlled substance under the controlled substances act. buprenorphine, like morphine and other opioids, has the potential for being abused and is subject to criminal diversion. this should be considered when prescribing or dispensing buprenorphine in situations when the clinician is concerned about an increased risk of misuse, abuse, or diversion. healthcare professionals should contact their state professional licensing board or state controlled substances authority for information on how to prevent and detect abuse or diversion of this product. patients who continue to misuse, abuse, or divert buprenorphine products or other opioids should be provided with, or referred to, more intensive and structured treatment. abuse of buprenorphine poses a risk of overdose and death. this risk is increased with the abuse of buprenorphine and alcohol and other substances, especially benzodiazepines. the healthcare provider may be able to more easily detect misuse or diversion by maintaining records of medication prescribed including date, dose, quantity, frequency of refills, and renewal requests of medication prescribed. proper assessment of the patient, proper prescribing practices, periodic re-evaluation of therapy, and proper handling and storage of the medication are appropriate measures that help to limit abuse of opioid drugs. buprenorphine is a partial agonist at the mu-opioid receptor and chronic administration produces physical dependence of the opioid-type, characterized by moderate withdrawal signs and symptoms upon abrupt discontinuation or rapid taper. the withdrawal syndrome is typically milder than seen with full agonists and may be delayed in onset [see warnings and precautions (5.7)] . neonatal opioid withdrawal syndrome (nows) is an expected and treatable outcome of prolonged use of opioids during pregnancy [see warnings and precautions (5.5)] . instructions for use buprenorphine (bue’’ pre nor’ feen) and naloxone (nal ox’ one) sublingual tablets (ciii) this “instructions for use” contains information on how to correctly take buprenorphine and naloxone sublingual tablets. important information you need to know before taking buprenorphine and naloxone sublingual tablets: - your healthcare provider should show you how to take buprenorphine and naloxone sublingual tablets the right way. preparing to take buprenorphine and naloxone sublingual tablets: - put the tablets under your tongue. let them dissolve completely. - while buprenorphine and naloxone sublingual tablets are dissolving, do not chew or swallow the tablet because the medicine will not work as well. - talking while the tablet is dissolving can affect how well the medicines in buprenorphine and naloxone sublingual tablets are absorbed. - after buprenorphine and naloxone sublingual tablets is completely dissolved, rinse your mouth with water and swallow. wait for at least one hour before brushing teeth. - if you miss a dose of buprenorphine and naloxone sublingual tablets, take your medicine when you remember. if it is almost time for your next dose, skip the missed dose and take the next dose at your regular time. do not take 2 doses at the same time unless your healthcare provider tells you to. if you are not sure about your dosing, call your healthcare provider. - do not stop taking buprenorphine and naloxone sublingual tablets suddenly. you could become sick and have withdrawal symptoms because your body has become used to the medicine. physical dependence is not the same as drug addiction. your healthcare provider can tell you more about the differences between physical dependence and drug addiction. to have fewer withdrawal symptoms, ask your healthcare provider how to stop using buprenorphine and naloxone sublingual tablets the right way. if you take too much buprenorphine and naloxone sublingual tablets or overdose, call poison control or get emergency medical help right away. storing buprenorphine and naloxone sublingual tablets: - store buprenorphine and naloxone sublingual tablets at room temperature between 59°f and 86°f (15°c to 30°c). - keep buprenorphine and naloxone sublingual tablets in a safe place, out of the sight and reach of children. disposing of buprenorphine and naloxone sublingual tablets: - dispose of unused buprenorphine and naloxone sublingual tablets as soon as you no longer need them. - dispose of expired, unwanted or unused buprenorphine and naloxone sublingual tablets by promptly flushing down the toilet (if a drug take-back option is not readily available). visit www.fda.gov/drugdisposal for additional information on disposal of unused medicines. if you need help with disposal of buprenorphine and naloxone sublingual tablets, call 1-800-845-8210. this

pai holdings, llc - levetiracetam (unii: 44yrr34555) (levetiracetam - unii:44yrr34555) - levetiracetam 100 mg in 1 ml - levetiracetam oral solution usp is indicated for the treatment of partial-onset seizures in patients 1 month of age and older. levetiracetam oral solution usp is indicated as adjunctive therapy for the treatment of myoclonic seizures in patients 12 years of age and older with juvenile myoclonic epilepsy. levetiracetam oral solution usp is indicated as adjunctive therapy for the treatment of primary generalized tonic-clonic seizures in patients 6 years of age and older with idiopathic generalized epilepsy. levetiracetam oral solution usp is contraindicated in patients with a hypersensitivity to levetiracetam. reactions have included anaphylaxis and angioedema [ see warnings and precautions (5.4)]. pregnancy exposure registry there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antiepileptic drugs (aeds), including levetiracetam, during pregnancy. encourage women who are taking levetiracetam during pregnancy to enroll in the north american antiepileptic drug (naaed) pregnancy registry by calling 1-888-233-2334 or visiting http://www.aedpregnancyregistry.org/. risk summary prolonged experience with levetiracetam in pregnant women has not identified a drug-associated risk of major birth defects or miscarriage, based on published literature, which includes data from pregnancy registries and reflects experience over two decades [see human data ]. in animal studies, levetiracetam produced developmental toxicity (increased embryofetal and offspring mortality, increased incidences of fetal structural abnormalities, decreased embryofetal and offspring growth, neurobehavioral alterations in offspring) at doses similar to human therapeutic doses [see animal data ]. in the u.s. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. the background risk of major birth defects and miscarriage for the indicated population is unknown. clinical considerations levetiracetam blood levels may decrease during pregnancy [see warnings and precautions (5.10) ]. physiological changes during pregnancy may affect levetiracetam concentration. decrease in levetiracetam plasma concentrations has been observed during pregnancy. this decrease is more pronounced during the third trimester. dose adjustments may be necessary to maintain clinical response. data human data while available studies cannot definitively establish the absence of risk, data from the published literature and pregnancy registries have not established an association with levetiracetam use during pregnancy and major birth defects or miscarriage. animal data when levetiracetam (0, 400, 1200, or 3600 mg/kg/day) was administered orally to pregnant rats during the period of organogenesis, reduced fetal weights and increased incidence of fetal skeletal variations were observed at the highest dose tested. there was no evidence of maternal toxicity. the no-effect dose for adverse effects on embryofetal developmental in rats (1200 mg/kg/day) is approximately 4 times the maximum recommended human dose (mrhd) of 3000 mg on a body surface area (mg/m2 ) basis. oral administration of levetiracetam (0, 200, 600, or 1800 mg/kg/day) to pregnant rabbits during the period of organogenesis resulted in increased embryofetal mortality and incidence of fetal skeletal variations at the mid and high dose and decreased fetal weights and increased incidence of fetal malformations at the high dose, which was associated with maternal toxicity. the no-effect dose for adverse effects on embryofetal development in rabbits (200 mg/kg/day) is approximately equivalent to the mrhd on a mg/m2 basis. oral administration of levetiracetam (0, 70, 350, or 1800 mg/kg/day) to female rats throughout pregnancy and lactation led to an increased incidence of fetal skeletal variations, reduced fetal body weight, and decreased growth in offspring at the mid and high doses and increased pup mortality and neurobehavioral alterations in offspring at the highest dose tested. there was no evidence of maternal toxicity. the no-effect dose for adverse effects on pre-and postnatal development in rats (70 mg/kg/day) is less than the mrhd on a mg/m2 basis. oral administration of levetiracetam to rats during the latter part of gestation and throughout lactation produced no adverse developmental or maternal effects at doses of up to 1800 mg/kg/day (6 times the mrhd on a mg/m2 basis). risk summary levetiracetam is excreted in human milk. there are no data on the effects of levetiracetam on the breastfed infant, or the effects on milk production. the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for levetiracetam and any potential adverse effects on the breastfed infant from levetiracetam or from the underlying maternal condition.  the safety and effectiveness of levetiracetam for the treatment of partial-onset seizures in patients 1 month to 16 years of age have been established [see clinical pharmacology (12.3) and clinical studies (14.1) ].  the dosing recommendation in these pediatric patients varies according to age group and is weight-based [see dosage and administration (2.2) ]. the safety and effectiveness of levetiracetam as adjunctive therapy for the treatment of myoclonic seizures in adolescents 12 years of age and older with juvenile myoclonic epilepsy have been established [see clinical studies (14.2) ]. the safety and effectiveness of levetiracetam as adjunctive therapy for the treatment of primary generalized tonic-clonic seizures in pediatric patients 6 years of age and older with idiopathic generalized epilepsy have been established [see clinical studies (14.3) ]. safety and effectiveness for the treatment of partial-onset seizures in pediatric patients below the age of 1 month; adjunctive therapy for the treatment of myoclonic seizures in pediatric patients below the age of 12 years; and adjunctive therapy for the treatment of primary generalized tonic-clonic seizures in pediatric patients below the age of 6 years have not been established. a 3-month, randomized, double-blind, placebo-controlled study was performed to assess the neurocognitive and behavioral effects of levetiracetam as adjunctive therapy in 98 (levetiracetam n=64, placebo n=34) pediatric patients, ages 4 to 16 years old, with partial seizures that were inadequately controlled.  the target dose was 60 mg/kg/day.   neurocognitive effects were measured by the leiter-r attention and memory (am) battery, which measures various aspects of a child’s memory and attention.  although no substantive differences were observed between the placebo and drug treated groups in the median change from baseline in this battery, the study was not adequate to assess formal statistical non-inferiority of the drug and placebo.  the achenbach child behavior checklist (cbcl/6-18), a standardized validated tool used to assess a child’s competencies and behavioral/emotional problems, was also assessed in this study.  an analysis of the cbcl/6-18 indicated on average a worsening in levetiracetam-treated patients in aggressive behavior, one of the eight syndrome scores [see warnings and precautions (5.1) ]. juvenile animal toxicity data studies of levetiracetam in juvenile rats (dosed on postnatal days 4 through 52) and dogs (dosed from postnatal weeks 3 through 7) at doses of up to 1800 mg/kg/day (approximately 7 and 24 times, respectively, the maximum recommended pediatric dose of 60 mg/kg/day on a mg/m2 basis) did not demonstrate adverse effects on postnatal development. there were 347 subjects in clinical studies of levetiracetam that were 65 and over. no overall differences in safety were observed between these subjects and younger subjects. there were insufficient numbers of elderly subjects in controlled trials of epilepsy to adequately assess the effectiveness of levetiracetam in these patients. levetiracetam is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function [ see clinical pharmacology (12.3) ]. clearance of levetiracetam is decreased in patients with renal impairment and is correlated with creatinine clearance [ see clinical pharmacology (12.3) ]. dose adjustment is recommended for patients with impaired renal function and supplemental doses should be given to patients after dialysis [ see dosage and administration (2.5) ].

"drug-seeking" behavior is very common in persons with substance use disorders. drug-seeking tactics include emergency calls or visits near the end of office hours, refusal to undergo appropriate examination, testing, or referral, repeated "loss" of prescriptions, tampering with prescriptions and reluctance to provide prior medical records or contact information for other treating healthcare provider(s). "doctor shopping" (visiting multiple prescribers to obtain additional prescriptions) is common among drug abusers and people suffering from untreated addiction. preoccupation with achieving adequate pain relief can be appropriate behavior in a patient with poor pain control. abuse and addiction are separate and distinct from physical dependence and tolerance. healthcare providers should be aware that addiction may not be accompanied by concurrent tolerance and symptoms of physical dependence in all addicts. in addition, abuse of opioids can occur in the absence of true addiction. acetaminophen and codeine phosphate oral solution, like other opioids, can be diverted for non-medical use into illicit channels of distribution. careful record-keeping of prescribing information, including quantity, frequency, and renewal requests, as required by state and federal law, is strongly advised. proper assessment of the patient, proper prescribing practices, periodic re-evaluation of therapy, and proper dispensing and storage are appropriate measures that help to limit abuse of opioid drugs. acetaminophen and codeine phosphate oral solution is for oral use only. abuse of acetaminophen and codeine phosphate oral solution poses a risk of overdose and death. the risk is increased with concurrent use of acetaminophen and codeine phosphate oral solution with alcohol and other central nervous system depressants. parenteral drug abuse is commonly associated with transmission of infectious diseases such as hepatitis and hiv. both tolerance and physical dependence can develop during chronic opioid therapy. tolerance is the need for increasing doses of opioids to maintain a defined effect such as analgesia (in the absence of disease progression or other external factors). tolerance may occur to both the desired and undesired effects of drugs, and may develop at different rates for different effects. physical dependence is a physiological state in which the body adapts to the drug after a period of regular exposure, resulting in withdrawal symptoms after abrupt discontinuation or a significant dosage reduction of a drug. withdrawal also may be precipitated through the administration of drugs with opioid antagonist activity (e.g., naloxone, nalmefene), mixed agonist/antagonist analgesics (e.g., pentazocine, butorphanol, nalbuphine), or partial agonists (e.g., buprenorphine). physical dependence may not occur to a clinically significant degree until after several days to weeks of continued opioid usage. do not abruptly discontinue acetaminophen and codeine phosphate oral solution in a patient physically dependent on opioids. rapid tapering of acetaminophen and codeine phosphate oral solution in a patient physically dependent on opioids may lead to serious withdrawal symptoms, uncontrolled pain, and suicide. rapid discontinuation has also been associated with attempts to find other sources of opioid analgesics, which may be confused with drug-seeking for abuse. when discontinuing acetaminophen and codeine phosphate oral solution, gradually taper the dosage using a patient-specific plan that considers the following: the dose of acetaminophen and codeine phosphate oral solution the patient has been taking, the duration of treatment, and the physical and psychological attributes of the patient. to improve the likelihood of a successful taper and minimize withdrawal symptoms, it is important that the opioid tapering schedule is agreed upon by the patient. in patients taking opioids for a long duration at high doses, ensure that a multimodal approach to pain management, including mental health support (if needed), is in place prior to initiating an opioid analgesic taper [see dosage and administration, warnings ]. infants born to mothers physically dependent on opioids will also be physically dependent and may exhibit respiratory difficulties and withdrawal signs [see precautions; pregnancy ].
