ajanta pharma usa inc. - amlodipine besylate (unii: 864v2q084h) (amlodipine - unii:1j444qc288), olmesartan medoxomil (unii: 6m97xtv3hd) (olmesartan - unii:8w1iqp3u10) - amlodipine 5 mg - amlodipine and olmesartan medoxomil tablets are indicated for the treatment of hypertension, alone or with other antihypertensive agents, to lower blood pressure. lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular (cv) events, primarily strokes and myocardial infarctions. these benefits have been seen in controlled trials of antihypertensive drugs from a wide variety of pharmacologic classes including the class to which this drug principally belongs. there are no controlled trials demonstrating risk reduction with amlodipine and olmesartan medoxomil tablets. control of high blood pressure should be part of comprehensive cardiovascular risk management, including, as appropriate, lipid control, diabetes management, antithrombotic therapy, smoking cessation, exercise, and limited sodium intake. many patients will require more than one drug to achieve blood pressure goals. for specific advice on goals and management, see published guidelines, such as those of the national high blood pressure education program’s joint national committee on prevention, detection, evaluation, and treatment of high blood pressure (jnc). numerous antihypertensive drugs, from a variety of pharmacologic classes and with different mechanisms of action, have been shown in randomized controlled trials to reduce cardiovascular morbidity and mortality, and it can be concluded that it is blood pressure reduction, and not some other pharmacologic property of the drugs, that is largely responsible for those benefits. the largest and most consistent cardiovascular outcome benefit has been a reduction in the risk of stroke, but reductions in myocardial infarction and cardiovascular mortality also have been seen regularly. elevated systolic or diastolic pressure causes increased cardiovascular risk, and the absolute risk increase per mmhg is greater at higher blood pressures, so that even modest reductions of severe hypertension can provide substantial benefit. relative risk reduction from blood pressure reduction is similar across populations with varying absolute risk, so the absolute benefit is greater in patients who are at higher risk independent of their hypertension (for example, patients with diabetes or hyperlipidemia), and such patients would be expected to benefit from more aggressive treatment to a lower blood pressure goal. some antihypertensive drugs have smaller blood pressure effects (as monotherapy) in black patients, and many antihypertensive drugs have additional approved indications and effects (e.g., on angina, heart failure, or diabetic kidney disease). these considerations may guide selection of therapy. amlodipine and olmesartan medoxomil tablets may also be used as initial therapy in patients who are likely to need multiple antihypertensive agents to achieve their blood pressure goals. patients with moderate or severe hypertension are at relatively high risk for cardiovascular events (such as strokes, heart attacks, and heart failure), kidney failure, and vision problems, so prompt treatment is clinically relevant. the decision to use a combination as initial therapy should be individualized and should be shaped by considerations such as baseline blood pressure, the target goal, and the incremental likelihood of achieving goal with a combination compared to monotherapy. individual blood pressure goals may vary based upon the patient’s risk. data from an 8-week, placebo-controlled, parallel-group factorial study [see clinical studies (14.1)] provide estimates of the probability of reaching a blood pressure goal with amlodipine and olmesartan medoxomil tablets compared to amlodipine or olmesartan medoxomil monotherapy. the figures below provide estimates of the likelihood of achieving the targeted systolic or diastolic blood pressure goals with amlodipine and olmesartan medoxomil tablets 10/40 mg compared with amlodipine or olmesartan medoxomil monotherapy, based upon baseline systolic or diastolic blood pressure. the curve of each treatment group was estimated by logistic regression modeling from all available data of that treatment group. the right tail of each curve is less reliable because of small numbers of subjects with high baseline blood pressures.      the figures above provide an approximation of the likelihood of reaching a targeted blood pressure goal (e.g., week 8 sbp <140 mmhg or <130 mmhg or a dbp <90 mmhg or <80 mmhg) for the high-dose treatment groups evaluated in the study. amlodipine and olmesartan medoxomil tablets 5/20 mg, the lowest dose combination treatment group, increases the probability of reaching blood pressure goal compared with the highest dose monotherapies, amlodipine 10 mg and olmesartan medoxomil 40 mg. for example, a patient with a baseline blood pressure of 160/100 mmhg has about a 48% likelihood of achieving a goal of <140 mmhg (systolic) and a 51% likelihood of achieving a goal of <90 mmhg (diastolic) on monotherapy with olmesartan medoxomil 40 mg, and about a 46% likelihood of achieving a goal of <140 mmhg (systolic) and a 60% likelihood of achieving a goal of <90 mmhg (diastolic) on monotherapy with amlodipine 10 mg. the likelihood of achieving these same goals increases to 63% (systolic) and 71% (diastolic) on amlodipine and olmesartan medoxomil tablets 5/20 mg, and to 68% (systolic) and 85% (diastolic) on amlodipine and olmesartan medoxomil tablets 10/40 mg. do not co-administer aliskiren with amlodipine and olmesartan medoxomil tablets in patients with diabetes [see drug interactions ( 7.2 )]. risk summary amlodipine and olmesartan medoxomil tablets can cause fetal harm when administered to a pregnant woman. use of drugs that act on the renin-angiotensin system during the second and third trimesters of pregnancy reduces fetal renal function and increases fetal and neonatal morbidity and death [see clinical considerations]. most epidemiologic studies examining fetal abnormalities after exposure to antihypertensive use in the first trimester have not distinguished drugs affecting the renin-angiotensin system from other antihypertensive agents. when pregnancy is detected, discontinue amlodipine and olmesartan medoxomil tablets as soon as possible. consider alternative antihypertensive therapy during pregnancy. 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 hypertension in pregnancy increases the maternal risk for pre-eclampsia, gestational diabetes, premature delivery, and delivery complications (e.g., need for cesarean section and post-partum hemorrhage). hypertension increases the fetal risk for intrauterine growth restriction and intrauterine death. pregnant women with hypertension should be carefully monitored and managed accordingly. fetal/neonatal adverse reactions olmesartan medoxomil oligohydramnios in pregnant women who use drugs affecting the renin-angiotensin system in the second and third trimesters of pregnancy can result in the following: reduced fetal renal function leading to anuria and renal failure, fetal lung hypoplasia, skeletal deformations, including skull hypoplasia, hypotension, and death. perform serial ultrasound examinations to assess the intra-amniotic environment. fetal testing may be appropriate, based on the week of gestation. patients and physicians should be aware, however, that oligohydramnios may not appear until after the fetus has sustained irreversible injury. closely observe infants with histories of in utero exposure to olmesartan for hypotension, oliguria, and hyperkalemia. in neonates with a history of in utero exposure to olmesartan, if oliguria or hypotension occur, utilize measures to maintain adequate blood pressure and renal perfusion. exchange transfusions or dialysis may be required as a means of reversing hypotension and supporting renal function [see use in specific populations (8.4)]. data animal data no reproductive studies have been conducted with the combination of olmesartan medoxomil, and amlodipine. however, these studies have been conducted for olmesartan medoxomil and amlodipine alone. olmesartan medoxomil no teratogenic effects were observed when olmesartan medoxomil was administered to pregnant rats at oral doses up to 1000 mg/kg/day (240 times the maximum recommended human dose [mrhd] on a mg/m2 basis) or pregnant rabbits at oral doses up to 1 mg/kg/day (half the mrhd on a mg/m2 basis; higher doses could not be evaluated for effects on fetal development as they were lethal to the does). in rats, significant decreases in pup birth weight and weight gain were observed at doses ≥1.6 mg/kg/day, and delays in developmental milestones (delayed separation of ear auricular, eruption of lower incisors, appearance of abdominal hair, descent of testes, and separation of eyelids) and dose-dependent increases in the incidence of dilation of the renal pelvis were observed at doses ≥ 8 mg/kg/day. the no observed effect dose for developmental toxicity in rats is 0.3 mg/kg/day, about one-tenth the mrhd of 40 mg/day. amlodipine  no evidence of teratogenicity or other embryo/fetal toxicity was found when pregnant rats and rabbits were treated orally with amlodipine maleate at doses of up to 10mg amlodipine/kg/day (respectively about 10 and 20 times the maximum recommended human dose of 10 mg amlodipine on a mg/m2 basis) during their respective periods of major organogenesis (calculations based on a patient weight of 60 kg). however, litter size was significantly decreased (by about 50%), and the number of intrauterine deaths was significantly increased (about 5-fold) in rats receiving amlodipine maleate at a dose equivalent to 10 mg amlodipine/kg/day for 14 days before mating and throughout mating and gestation. amlodipine maleate has been shown to prolong both the gestational period and the duration of labor in rats at this dose. risk summary there is limited information regarding the presence of amlodipine and olmesartan medoxomil tablets in human milk, the effects on the breastfed infant, or the effects on milk production. amlodipine is present in human milk. olmesartan is present in rat milk [see data] . because of the potential for adverse effects on the nursing infant, advise a nursing woman that breastfeeding is not recommended during treatment with amlodipine and olmesartan medoxomil tablets. data presence of olmesartan in milk was observed after a single oral administration of 5 mg/kg [14 c] olmesartan medoxomil to lactating rats. the safety and effectiveness of amlodipine and olmesartan medoxomil tablets in pediatric patients have not been established. of the total number of subjects in the double-blind clinical study of amlodipine and olmesartan medoxomil tablets, 20% (384/1940) were 65 years of age or older and 3% (62/1940) were 75 years or older. no overall differences in safety or effectiveness were observed between subjects 65 years of age or older and younger subjects. elderly patients have decreased clearance of amlodipine. starting amlodipine or adding amlodipine at 2.5 mg in patients ≥75 years old is recommended. the lowest dose of amlodipine and olmesartan medoxomil tablets is 5/20 mg; therefore, initial therapy with amlodipine and olmesartan medoxomil tablets is not recommended in patients ≥75 years old. amlodipine. 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, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. elderly patients have decreased clearance of amlodipine with a resulting increase of auc of approximately 40% to 60%, and a lower initial dose may be required. olmesartan medoxomil. of the total number of hypertensive patients receiving olmesartan medoxomil in clinical studies, more than 20% were 65 years of age and over, while more than 5% were 75 years of age and older. no overall differences in effectiveness or safety were observed between elderly patients and younger patients. other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. there are no studies of amlodipine and olmesartan medoxomil tablets in patients with hepatic insufficiency, but both amlodipine and olmesartan medoxomil show moderate increases in exposure in patients with hepatic impairment. the recommended initial dose of amlodipine in patients with severe hepatic impairment is 2.5 mg, a dose not available with amlodipine and olmesartan medoxomil tablets. amlodipine. amlodipine is extensively metabolized by the liver and the plasma elimination half-life (t½) is 56 hours in patients with severely impaired hepatic function [see warnings and precautions (5.5)] . olmesartan medoxomil. increases in auc0-∞ and peak plasma concentration (cmax) for olmesartan were observed with moderate hepatic impairment compared to those in matched controls with an increase in auc of about 60%. there are no studies of amlodipine and olmesartan medoxomil tablets in patients with renal impairment. amlodipine. the pharmacokinetics of amlodipine are not significantly influenced by renal impairment. patients with renal failure may therefore receive the usual initial dose. olmesartan medoxomil. patients with renal insufficiency have elevated serum concentrations of olmesartan compared with patients with normal renal function. after repeated dosing, auc was approximately tripled in patients with severe renal impairment (creatinine clearance <20 ml/min). no initial dosage adjustment is recommended for patients with moderate to marked renal impairment (creatinine clearance <40 ml/min). of the total number of subjects in the double-blind clinical study of amlodipine and olmesartan medoxomil tablets, 25% (481/1940) were black patients. amlodipine and olmesartan medoxomil tablets were effective in treating black patients (usually a low-renin population), and the magnitude of blood pressure reduction in black patients approached that observed for non-black patients.

and amlodipine tablets are indicated for the treatment of hypertension, alone or with other antihypertensive agents to lower blood pressure. lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions. these benefits have been seen in controlled trials of antihypertensive drugs from a wide variety of pharmacologic classes including angiotensin ii receptor blockers and dihydropyridine calcium channel blockers. there are no controlled trials demonstrating risk reduction with telmisartan and amlodipine tablets. control of high blood pressure should be part of comprehensive cardiovascular risk management, including, as appropriate, lipid control, diabetes management, antithrombotic therapy, smoking cessation, exercise, and limited sodium intake. many patients will require more than one drug to achieve blood pressure goals. for specific advice on goals and management, see published guidelines, such as those of the national high blood pressure education program's joint national committee on prevention, detection, evaluation, and treatment of high blood pressure (jnc). numerous antihypertensive drugs, from a variety of pharmacologic classes and with different mechanisms of action, have been shown in randomized controlled trials to reduce cardiovascular morbidity and mortality, and it can be concluded that it is blood pressure reduction, and not some other pharmacologic property of the drugs, that is largely responsible for those benefits. the largest and most consistent cardiovascular outcome benefit has been a reduction in the risk of stroke, but reductions in myocardial infarction and cardiovascular mortality also have been seen regularly. elevated systolic or diastolic pressure causes increased cardiovascular risk, and the absolute risk increase per mmhg is greater at higher blood pressures, so that even modest reductions of severe hypertension can provide substantial benefit. relative risk reduction from blood pressure reduction is similar across populations with varying absolute risk, so the absolute benefit is greater in patients who are at higher risk independent of their hypertension (for example, patients with diabetes or hyperlipidemia), and such patients would be expected to benefit from more aggressive treatment to a lower blood pressure goal. some antihypertensive drugs have smaller blood pressure effects (as monotherapy) in black patients, and many antihypertensive drugs have additional approved indications and effects (e.g., on angina, heart failure, or diabetic kidney disease). these considerations may guide selection of therapy. telmisartan and amlodipine tablets may also be used as initial therapy in patients who are likely to need multiple drugs to achieve their blood pressure goals. base the choice of telmisartan and amlodipine tablets as initial therapy for hypertension on an assessment of potential benefits and risks including whether the patient is likely to tolerate the starting dose of telmisartan and amlodipine tablets. patients with moderate or severe hypertension are at relatively high risk for cardiovascular events (such as strokes, heart attacks, and heart failure), kidney failure, and vision problems, so prompt treatment is clinically relevant. consider the patient's baseline blood pressure, the target goal, and the incremental likelihood of achieving goal with a combination compared with monotherapy when deciding whether to use telmisartan and amlodipine tablets as initial therapy. individual blood pressure goals may vary based upon the patient's risk. data from an 8-week, placebo-controlled, multidose, factorial trial provide estimates of the probability of reaching a blood pressure goal with telmisartan and amlodipine tablets compared to telmisartan or amlodipine monotherapy and placebo [see clinical studies (14.1)]. the figures below provide estimates of the likelihood of achieving systolic and diastolic blood pressure control with telmisartan and amlodipine tablets 80/10 mg, based upon baseline systolic or diastolic blood pressure. the curve of each treatment group was estimated by logistic regression modeling. the estimated likelihood at the right tail of each curve is less reliable due to small numbers of subjects with high baseline blood pressures. figure 1a: probability of achieving systolic blood pressure <140 mmhg at week 8 figure 1b: probability of achieving systolic blood pressure <130 mmhg at week 8 figure 2a: probability of achieving diastolic blood pressure <90 mmhg at week 8 figure 2b: probability of achieving diastolic blood pressure <80 mmhg at week 8 the figures above provide an approximation of the likelihood of reaching a targeted blood pressure goal at 8 weeks. for example, a patient with a baseline blood pressure of 160/110 mmhg has about a 16% likelihood of achieving a goal of <140 mmhg (systolic) and 16% likelihood of achieving <90 mmhg (diastolic) on placebo. the likelihood of achieving these same goals on telmisartan is about 46% (systolic) and 26% (diastolic). the likelihood of achieving these same goals on amlodipine is about 69% (systolic) and 22% (diastolic). these likelihoods rise to 79% for systolic and 55% for diastolic with telmisartan and amlodipine tablets. telmisartan and amlodipine tablets are contraindicated in patients with known hypersensitivity (e.g., anaphylaxis or angioedema) to telmisartan, amlodipine, or any other component of this product [see adverse reactions (6.2)]. do not co-administer aliskiren with telmisartan and amlodipine tablets in patients with diabetes [see drug interactions (7.2)]. risk summary telmisartan and amlodipine tablets can cause fetal harm when administered to a pregnant woman. use of drugs that act on the renin-angiotensin system during the second and third trimesters of pregnancy reduces fetal renal function and increases fetal and neonatal morbidity and death (see clinical considerations) . most epidemiologic studies examining fetal abnormalities after exposure to antihypertensive use in the first trimester have not distinguished drugs affecting the renin-angiotensin system from other antihypertensive agents. studies in rats and rabbits with telmisartan showed fetotoxicity only at maternally toxic doses (see data) . in animal reproduction studies, there was no evidence of adverse developmental effects when pregnant rats and rabbits were treated orally with amlodipine maleate during organogenesis at doses approximately 10 and 20-times the maximum recommended human dose (mrhd), respectively. however for rats, litter size was significantly decreased (by about 50%) and the number of intrauterine deaths was significantly increased (about 5-fold). amlodipine has been shown to prolong both the gestation period and the duration of labor in rats at this dose (see data ). when pregnancy is detected, discontinue telmisartan and amlodipine tablets as soon as possible. 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 malformations 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:   hypertension in pregnancy increases the maternal risk for pre-eclampsia, gestational diabetes, premature delivery, and delivery complications (e.g., need for cesarean section, and post-partum hemorrhage). hypertension increases the fetal risk for intrauterine growth restriction and intrauterine death. pregnant women with hypertension should be carefully monitored and managed accordingly. fetal/neonatal adverse reactions: use of drugs that act on the ras in the second and third trimesters of pregnancy can result in the following: oligohydramnios, reduced fetal renal function leading to anuria and renal failure, fetal lung hypoplasia, skeletal deformations, including skull hypoplasia, hypotension, and death. in the unusual case that there is no appropriate alternative to therapy with drugs affecting the renin-angiotensin system for a particular patient, apprise the mother of the potential risk to the fetus. in patients taking telmisartan and amlodipine tablets during pregnancy, perform serial ultrasound examinations to assess the intra-amniotic environment. fetal testing may be appropriate, based on the week of gestation. if oligohydramnios is observed, discontinue telmisartan and amlodipine tablets, unless it is considered lifesaving for the mother. patients and physicians should be aware, however, that oligohydramnios may not appear until after the fetus has sustained irreversible injury. closely observe infants with histories of in utero exposure to telmisartan and amlodipine tablets for hypotension, oliguria, and hyperkalemia. if oliguria or hypotension occurs, support blood pressure and renal perfusion. exchange transfusions or dialysis may be required as a means of reversing hypotension and/or substituting for disordered renal function [see use in specific populations (8.4)] . data animal data: no reproductive toxicity studies have been conducted with the combination of telmisartan and amlodipine besylate. however, these studies have been conducted for telmisartan and amlodipine besylate alone. telmisartan: no teratogenic effects were observed when telmisartan was administered to pregnant rats at oral doses of up to 50 mg/kg/day and to pregnant rabbits at oral doses up to 45 mg/kg/day. in rabbits, embryolethality associated with maternal toxicity (reduced body weight gain and food consumption) was observed at 45 mg/kg/day [about 12 times the maximum recommended human dose (mrhd) of 80 mg on a mg/m2 basis]. in rats, maternally toxic (reduction in body weight gain and food consumption) telmisartan doses of 15 mg/kg/day (about 1.9 times the mrhd on a mg/m2 basis), administered during late gestation and lactation, were observed to produce adverse effects in neonates, including reduced viability, low birth weight, delayed maturation, and decreased weight gain. the no observed effect doses for developmental toxicity in rats and rabbits, 5 and 15 mg/kg/day, respectively, are about 0.64 and 3.7 times, on a mg/m2 basis, the maximum recommended human dose of telmisartan (80 mg/day). amlodipine: no evidence of teratogenicity or embryo/fetal toxicity was found when pregnant rats and rabbits were treated orally with amlodipine maleate at doses up to 10 mg amlodipine/kg/day (approximately 10 and 20 times the mrhd based on body surface area, respectively) during their respective periods of major organogenesis. however, for rats, litter size was significantly decreased (by about 50%) and the number of intrauterine deaths was significantly increased (about 5-fold). amlodipine has been shown to prolong both the gestation period and the duration of labor in rats at this dose. risk summary there is no information regarding the presence of telmisartan and amlodipine tablets or telmisartan in human milk, the effects on the breastfed infant, or the effects on milk production. limited published studies report that amlodipine is present in human milk. however, there is insufficient information to determine the effects of amlodipine on the breastfed infant. there is no available information on the effects of amlodipine on milk production. telmisartan is present in the milk of lactating rats (see data) . because of the potential for serious adverse reactions in the breastfed infant including hypotension, hyperkalemia and renal impairment, advise a nursing woman not to breastfeed during treatment with telmisartan and amlodipine tablets. data: telmisartan was present in the milk of lactating rats at concentrations 1.5 to 2 times those found in plasma from 4 to 8 hours after administration. safety and effectiveness of telmisartan and amlodipine tablets in pediatric patients have not been established. neonates with a history of in utero exposure to telmisartan and amlodipine if oliguria or hypotension occurs, support blood pressure and renal perfusion. exchange transfusions or dialysis may be required as a means of reversing hypotension and/or substituting for disordered renal function. telmisartan and amlodipine tablets of the total number of 3282 hypertensive patients receiving a telmisartan/amlodipine combination in clinical studies, 605 (18%) patients were 65 years of age or older and of these, 88 (3%) patients were 75 years and older. no overall differences in efficacy or safety of telmisartan and amlodipine tablets were observed in this patient population. telmisartan of the total number of patients receiving telmisartan in clinical studies, 551 (18.6%) were 65 to 74 years of age and 130 (4.4%) were 75 years and older. no overall differences in effectiveness and safety were observed in these patients compared to younger patients and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. amlodipine clinical studies of amlodipine besylate tablets did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. 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, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal or cardiac function, and of concomitant disease or other drug therapy. elderly patients have decreased clearance of amlodipine with a resulting increase of auc of approximately 40% to 60%, and a lower initial dose may be required. since patients age 75 and older have decreased clearance of amlodipine, start amlodipine or add amlodipine 2.5 mg to telmisartan. the lowest dose of telmisartan and amlodipine tablet is 40/5 mg; therefore, initial therapy with telmisartan and amlodipine tablets is not recommended in patients 75 years of age and older [see dosage and administration (2.5)]. monitor carefully and uptitrate slowly in patients with biliary obstructive disorders or hepatic insufficiency [see dosage and administration (2) and warnings and precautions (5.4)]. since patients with hepatic impairment have decreased clearance of amlodipine, start amlodipine or add amlodipine 2.5 mg to telmisartan. the lowest dose of telmisartan and amlodipine tablet is 40/5 mg; therefore, initial therapy with telmisartan and amlodipine tablet is not recommended in hepatically impaired patients [see dosage and administration (2.4)]. the magnitude of blood pressure lowering in black patients approached that observed in non-black patients but the number of black patients was limited (237 of 1461 patients).

ascend laboratories, llc - amlodipine besylate (unii: 864v2q084h) (amlodipine - unii:1j444qc288), olmesartan medoxomil (unii: 6m97xtv3hd) (olmesartan - unii:8w1iqp3u10) - amlodipine 5 mg - amlodipine

be shaped by considerations such as baseline blood pressure, the target goal, and the incremental likelihood of achieving goal with a combination compared to monotherapy. individual blood pressure goals may vary based upon the patient’s risk. data from an 8-week, placebo-controlled, parallel-group factorial study [see clinical studies (14.1) ] provide estimates of the probability of reaching a blood pressure goal with amlodipine and olmesartan medoxomil tablets compared to amlodipine or olmesartan medoxomil monotherapy. the figures below provide estimates of the likelihood of achieving the targeted systolic or diastolic blood pressure goals with amlodipine and olmesartan medoxomil tablets 10/40 mg compared with amlodipine or olmesartan medoxomil monotherapy, based upon baseline systolic or diastolic blood pressure. the curve of each treatment group was estimated by logistic regression modeling from all available data of that treatment group. the right tail of each curve is less reliable because of small numbers of subjects with high baseline blood pressures.   figure 1: probability of achieving systolic blood pressure (sbp) < 140 mmhg at week 8 with locf    figure 2: probability of achieving diastolic blood pressure (dbp) < 90 mmhg at week 8 with locf   figure 3: probability of achieving systolic blood pressure (sbp) < 130 mmhg at week 8 with locf   figure 4: probability of achieving diastolic blood pressure (dbp) < 80 mmhg at week 8 with locf the figures above provide an approximation of the likelihood of reaching a targeted blood pressure goal (e.g., week 8 sbp <140 mmhg or <130 mmhg or a dbp <90 mmhg or <80 mmhg) for the high-dose treatment groups evaluated in the study. amlodipine and olmesartan medoxomil tablets 5/20 mg, the lowest dose combination treatment group, increases the probability of reaching blood pressure goal compared with the highest dose monotherapies, amlodipine 10 mg and olmesartan medoxomil 40 mg. for example, a patient with a baseline blood pressure of 160/100 mmhg has about a 48% likelihood of achieving a goal of <140 mmhg (systolic) and a 51% likelihood of achieving a goal of <90 mmhg (diastolic) on monotherapy with olmesartan medoxomil 40 mg, and about a 46% likelihood of achieving a goal of <140 mmhg (systolic) and a 60% likelihood of achieving a goal of <90 mmhg (diastolic) on monotherapy with amlodipine 10 mg. the likelihood of achieving these same goals increases to 63% (systolic) and 71% (diastolic) on amlodipine and olmesartan medoxomil tablets 5/20 mg, and to 68% (systolic) and 85% (diastolic) on amlodipine and olmesartan medoxomil tablets 10/40 mg. do not co-administer aliskiren with amlodipine and olmesartan medoxomil tablets in patients with diabetes [see drug interactions (7.2 )]. risk summary amlodipine and olmesartan medoxomil tablets can cause fetal harm when administered to a pregnant woman. use of drugs that act on the renin-angiotensin system during the second and third trimesters of pregnancy reduces fetal renal function and increases fetal and neonatal morbidity and death [see clinical considerations]. most epidemiologic studies examining fetal abnormalities after exposure to antihypertensive use in the first trimester have not distinguished drugs affecting the renin-angiotensin system from other antihypertensive agents. when pregnancy is detected, discontinue amlodipine and olmesartan medoxomil tablets as soon as possible. consider alternative antihypertensive therapy during pregnancy. 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 hypertension in pregnancy increases the maternal risk for pre-eclampsia, gestational diabetes, premature delivery, and delivery complications (e.g., need for cesarean section and post-partum hemorrhage). hypertension increases the fetal risk for intrauterine growth restriction and intrauterine death. pregnant women with hypertension should be carefully monitored and managed accordingly. fetal/neonatal adverse reactions olmesartan medoxomil oligohydramnios in pregnant women who use drugs affecting the renin-angiotensin system in the second and third trimesters of pregnancy can result in the following: reduced fetal renal function leading to anuria and renal failure, fetal lung hypoplasia, skeletal deformations, including skull hypoplasia, hypotension, and death. perform serial ultrasound examinations to assess the intra-amniotic environment. fetal testing may be appropriate, based on the week of gestation. patients and physicians should be aware, however, that oligohydramnios may not appear until after the fetus has sustained irreversible injury. closely observe infants with histories of in utero exposure to olmesartan for hypotension, oliguria, and hyperkalemia. in neonates with a history of in utero exposure to olmesartan, if oliguria or hypotension occur, utilize measures to maintain adequate blood pressure and renal perfusion. exchange transfusions or dialysis may be required as a means of reversing hypotension and supporting renal function [see use in specific populations (8.4)]. data animal data no reproductive studies have been conducted with the combination of olmesartan medoxomil, and amlodipine. however, these studies have been conducted for olmesartan medoxomil and amlodipine alone. olmesartan medoxomil no teratogenic effects were observed when olmesartan medoxomil was administered to pregnant rats at oral doses up to 1000 mg/kg/day (240 times the maximum recommended human dose [mrhd] on a mg/m2 basis) or pregnant rabbits at oral doses up to 1 mg/kg/day (half the mrhd on a mg/m2 basis; higher doses could not be evaluated for effects on fetal development as they were lethal to the does). in rats, significant decreases in pup birth weight and weight gain were observed at doses ≥1.6 mg/kg/day, and delays in developmental milestones (delayed separation of ear auricular, eruption of lower incisors, appearance of abdominal hair, descent of testes, and separation of eyelids) and dose-dependent increases in the incidence of dilation of the renal pelvis were observed at doses ≥ 8 mg/kg/day. the no observed effect dose for developmental toxicity in rats is 0.3 mg/kg/day, about one-tenth the mrhd of 40 mg/day. amlodipine no evidence of teratogenicity or other embryo/fetal toxicity was found when pregnant rats and rabbits were treated orally with amlodipine maleate at doses of up to 10 mg amlodipine/kg/day (respectively about 10 and 20 times the maximum recommended human dose of 10 mg amlodipine on a mg/m2 basis) during their respective periods of major organogenesis (calculations based on a patient weight of 60 kg). however, litter size was significantly decreased (by about 50%), and the number of intrauterine deaths was significantly increased (about 5-fold) in rats receiving amlodipine maleate at a dose equivalent to 10 mg amlodipine/kg/day for 14 days before mating and throughout mating and gestation. amlodipine maleate has been shown to prolong both the gestational period and the duration of labor in rats at this dose. risk summary there is limited information regarding the presence of amlodipine and olmesartan medoxomil tablets in human milk, the effects on the breastfed infant, or the effects on milk production. amlodipine is present in human milk. olmesartan is present in rat milk [see data] . because of the potential for adverse effects on the nursing infant, advise a nursing woman that breastfeeding is not recommended during treatment with amlodipine and olmesartan medoxomil tablets. data presence of olmesartan in milk was observed after a single oral administration of 5 mg/kg [14 c] olmesartan medoxomil to lactating rats.  the safety and effectiveness of amlodipine and olmesartan medoxomil tablets in pediatric patients have not been established. of the total number of subjects in the double-blind clinical study of amlodipine and olmesartan medoxomil tablets, 20% (384/1940) were 65 years of age or older and 3% (62/1940) were 75 years or older. no overall differences in safety or effectiveness were observed between subjects 65 years of age or older and younger subjects. elderly patients have decreased clearance of amlodipine. starting amlodipine or adding amlodipine at 2.5 mg in patients ≥75 years old is recommended. the lowest dose of amlodipine and olmesartan medoxomil tablets is 5/20 mg; therefore, initial therapy with amlodipine and olmesartan medoxomil tablets is not recommended in patients ≥75 years old. amlodipine. 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, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. elderly patients have decreased clearance of amlodipine with a resulting increase of auc of approximately 40% to 60%, and a lower initial dose may be required. olmesartan medoxomil.  of the total number of hypertensive patients receiving olmesartan medoxomil in clinical studies, more than 20% were 65 years of age and over, while more than 5% were 75 years of age and older. no overall differences in effectiveness or safety were observed between elderly patients and younger patients. other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.  there are no studies of amlodipine and olmesartan medoxomil tablets in patients with hepatic insufficiency, but both amlodipine and olmesartan medoxomil show moderate increases in exposure in patients with hepatic impairment. the recommended initial dose of amlodipine in patients with severe hepatic impairment is 2.5 mg, a dose not available with amlodipine and olmesartan medoxomil tablets.   amlodipine.  amlodipine is extensively metabolized by the liver and the plasma elimination half-life (t½ ) is 56 hours in patients with severely impaired hepatic function [see warnings and precautions (5.5)] .   olmesartan medoxomil . increases in auc0-∞ and peak plasma concentration (cmax ) for olmesartan were observed with moderate hepatic impairment compared to those in matched controls with an increase in auc of about 60%. there are no studies of amlodipine and olmesartan medoxomil tablets in patients with renal impairment. amlodipine.  the pharmacokinetics of amlodipine are not significantly influenced by renal impairment. patients with renal failure may therefore receive the usual initial dose. olmesartan medoxomil. patients with renal insufficiency have elevated serum concentrations of olmesartan compared with patients with normal renal function. after repeated dosing, auc was approximately tripled in patients with severe renal impairment (creatinine clearance <20 ml/min). no initial dosage adjustment is recommended for patients with moderate to marked renal impairment (creatinine clearance <40 ml/min). of the total number of subjects in the double-blind clinical study of amlodipine and olmesartan medoxomil tablets, 25% (481/1940) were black patients. amlodipine and olmesartan medoxomil tablets was effective in treating black patients (usually a low-renin population), and the magnitude of blood pressure reduction in black patients approached that observed for non-black patients.

blocker (arb) class to which valsartan principally belongs. there are no controlled trials demonstrating risk reduction with amlodipine and valsartan tablets. control of high blood pressure should be part of comprehensive cardiovascular risk management, including, as appropriate, lipid control, diabetes management, antithrombotic therapy, smoking cessation, exercise, and limited sodium intake.

pressure is not adequately controlled on either monotherapy. amlodipine and valsartan tablets may also be used as initial therapy in patients who are likely to need multiple drugs to achieve their blood pressure goals. the choice of amlodipine and valsartan tablets as initial therapy for hypertension should be based on an assessment of potential benefits and risks including whether the patient

mmhg (systolic) and 80% likelihood of achieving <90 mmhg (diastolic) on amlodipine alone, and the likelihood of achieving these goals on valsartan alone is about 47% (systolic) or 62% (diastolic). the likelihood of achieving these goals on amlodipine and valsartan tablets rises to about 80% (systolic) or 85% (diastolic). the likelihood of achieving these goals on placebo is about 28% (systolic) or 37% (diastolic). do not use in patients with known hypersensitivity to any component. do not coadminister aliskiren with amlodipine and valsartan in patients with diabetes [see drug interactions (7)] . risk summary amlodipine and valsartan can cause fetal harm when administered to a pregnant woman. use of drugs that act on the renin-angiotensin system during the second and third trimesters of pregnancy reduces fetal renal function and increases fetal and neonatal morbidity and death. most epidemiologic studies examining fetal abnormalities after exposure to antihypertensive use in the first trimester have not distinguished drugs affecting the renin-angiotensin system from other antihypertensive agents. published reports include cases of anhydramnios and oligohydramnios in pregnant women treated with valsartan (see clinical considerations ). when pregnancy is detected, discontinue amlodipine and valsartan as soon as possible. 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: hypertension in pregnancy increases the maternal risk for pre-eclampsia, gestational diabetes, premature delivery, and delivery complications (e.g., need for cesarean section, and post-partum hemorrhage). hypertension increases the fetal risk for intrauterine growth restriction and intrauterine death. pregnant women with hypertension should be carefully monitored and managed accordingly. fetal/neonatal adverse reactions: oligohydramnios in pregnant women who use drugs affecting the renin-angiotensin system in the second and third trimesters of pregnancy can result in the following: reduced fetal renal function leading to anuria and renal failure, fetal lung hypoplasia, skeletal deformations, including skull hypoplasia, hypotension and death. perform serial ultrasound examinations to assess the intra-amniotic environment. fetal testing may be appropriate, based on the week of gestation. patients and physicians should be aware, however, that oligohydramnios may not appear until after the fetus has sustained irreversible injury. if oligohydramnios is observed, consider alternative drug treatment. closely observe neonates with histories of in utero exposure to amlodipine and valsartan for hypotension, oliguria, and hyperkalemia. in neonates with a history of in utero exposure to amlodipine and valsartan, if oliguria or hypotension occurs, support blood pressure and renal perfusion. exchange transfusions or dialysis may be required as a means of reversing hypotension and replacing renal function. data animal data: in rats, administered 20 mg/kg/day amlodipine plus 320 mg/kg/day valsartan, treatment-related maternal and fetal effects (developmental delays and alterations noted in the presence of significant maternal toxicity) were noted with the high dose combination. this corresponds to dose multiples of 9 and 19.5 times, respectively, the maximum recommended human dose (mrhd) of 10 mg/day for amlodipine and 320 mg/day for valsartan (based on body surface area and considering a 60 kg patient). risk summary there is limited information regarding the presence of amlodipine and valsartan in human milk, the effects on the breastfed infant, or the effects on milk production. valsartan is present in rat milk. limited published studies report that amlodipine is present in human milk. because of the potential for serious adverse reactions in breastfed infants, advise a nursing woman that breastfeeding is not recommended during treatment with amlodipine and valsartan tablets. data valsartan was detected in the milk of lactating rats 15 minutes after oral administration of a 3 mg/kg dose. safety and effectiveness of amlodipine and valsartan tablets in pediatric patients have not been established. in controlled clinical trials, 323 (22.5%) hypertensive patients treated with amlodipine and valsartan tablets were ≥65 years and 79 (5.5%) were ≥75 years. no overall differences in the efficacy or safety of amlodipine and valsartan tablets were observed in this patient population, but greater sensitivity of some older individuals cannot be ruled out. amlodipine the recommended starting dose of amlodipine 2.5 mg is not an available strength with amlodipine and valsartan tablets. clinical studies of amlodipine besylate tablets did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. 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, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal or cardiac function, and of concomitant disease or other drug therapy. elderly patients have decreased clearance of amlodipine with a resulting increase of area under the curve (auc) of approximately 40% to 60%. valsartan in the controlled clinical trials of valsartan, 1214 (36.2%) of hypertensive patients treated with valsartan were ≥65 years and 265 (7.9%) were ≥75 years. no overall difference in the efficacy or safety of valsartan was observed in this patient population, but greater sensitivity of some older individuals cannot be ruled out. safety and effectiveness of amlodipine and valsartan tablets in patients with severe renal impairment (crcl< 30 ml/min) have not been established. no dose adjustment is required in patients with mild (crcl 60 to 90 ml/min) or moderate (crcl 30 to 60 ml/min ) renal impairment. amlodipine exposure to amlodipine is increased in patients with hepatic insufficiency [see clinical pharmacology (12.3)]. the recommended initial dose of amlodipine in patients with hepatic impairment is 2.5 mg, which is not an available strength with amlodipine and valsartan tablets. valsartan no dose adjustment is necessary for patients with mild-to-moderate disease. no dosing recommendations can be provided for patients with severe liver disease.

remedyrepack inc. - alendronate sodium (unii: 2uy4m2u3ra) (alendronic acid - unii:x1j18r4w8p) - alendronic acid 70 mg - alendronate sodium tablets, usp are indicated for the treatment of osteoporosis in postmenopausal women. in postmenopausal women, alendronate sodium tablets, usp increases bone mass and reduces the incidence of fractures, including those of the hip and spine (vertebral compression fractures). [see clinical studies ( 14.1).] alendronate sodium tablets, usp are indicated for the prevention of postmenopausal osteoporosis [see clinical studies ( 14.2)]. alendronate sodium tablets, usp are indicated for treatment to increase bone mass in men with osteoporosis [see clinical studies ( 14.3)]. alendronate sodium tablets, usp are indicated for the treatment of glucocorticoid-induced osteoporosis in men and women receiving glucocorticoids in a daily dosage equivalent to 7.5 mg or greater of prednisone and who have low bone mineral density [see clinical studies ( 14.4)]. alendronate sodium tablets, usp are indicated for the treatment of paget's disease of bone in men and women. treatment is indicated in patients with paget's disease of bone who have alkaline phosphatase at least two times the upper limit of normal, or those who are symptomatic, or those at risk for future complications from their disease. [see clinical studies ( 14.5).] the optimal duration of use has not been determined. the safety and effectiveness of alendronate sodium for the treatment of osteoporosis are based on clinical data of four years duration. all patients on bisphosphonate therapy should have the need for continued therapy re-evaluated on a periodic basis. patients at low-risk for fracture should be considered for drug discontinuation after 3 to 5 years of use. patients who discontinue therapy should have their risk for fracture re-evaluated periodically. alendronate sodium tablets are contraindicated in patients with the following conditions: - inability to stand or sit upright for at least 30 minutes [see dosage and administration ( 2.6); warnings and precautions ( 5.1)] - hypocalcemia [see warnings and precautions ( 5.2)] - hypersensitivity to any component of this product. hypersensitivity reactions including urticaria and angioedema have been reported [see adverse reactions ( 6.2)] . risk summary available data on the use of alendronate sodium in pregnant women are insufficient to inform a drug-associated risk of adverse maternal or fetal outcomes. discontinue alendronate sodium when pregnancy is recognized. in animal reproduction studies, daily oral administration of alendronate to rats from before mating through the end of gestation or lactation showed decreased postimplantation survival and decreased pup body weight gain starting at doses equivalent to less than half of the highest recommended 40 mg clinical daily dose (based on body surface area, mg/m 2 ). oral administration of alendronate to rats during organogenesis resulted in reduced fetal ossification starting at doses 3 times the 40 mg clinical daily dose. no similar fetal effects were observed in pregnant rabbits dosed orally during organogenesis at doses equivalent to approximately 10 times the 40 mg clinical daily dose. delayed or failed delivery of offspring, protracted parturition, and late pregnancy maternal and fetal deaths due to maternal hypocalcemia occurred in rats at oral doses as low as one tenth the 40 mg clinical daily dose ( see data) . bisphosphonates are incorporated into the bone matrix, from which they are gradually released over a period of years. the amount of bisphosphonate incorporated into adult bone and available for release into the systemic circulation is directly related to the dose and duration of bisphosphonate use. consequently, based on the mechanism of action of bisphosphonates, there is a potential risk of fetal harm, predominantly skeletal, if a woman becomes pregnant after completing a course of bisphosphonate therapy. the impact of variables such as time between cessation of bisphosphonate therapy to conception, the particular bisphosphonate used, and the route of administration (intravenous versus oral) on the risk has not been studied. 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 defects, loss, or other adverse outcomes. in the u.s. general population, the estimated background risks of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. data animal data reproduction studies in rats dosed orally from before mating to the end of gestation or lactation showed decreased postimplantation survival starting at 2 mg/kg/day and decreased body weight gain starting at 1 mg/kg/day, doses equivalent to less than half the 40 mg clinical daily dose based on body surface area, mg/m 2 . incidence of incomplete fetal ossification in vertebral, skull, and sternebral bones were increased in rats dosed orally during organogenesis starting at 10 mg/kg/day (approximately 3 times the 40 mg clinical daily dose). no similar fetal effects were observed in pregnant rabbits dosed orally during organogenesis at up to 35 mg/kg/day (equivalent to approximately 10 times the 40 mg clinical daily dose). both total and ionized calcium decreased in pregnant rats dosed orally with 15 mg/kg/day alendronate (approximately 4 times the 40 mg clinical daily dose) resulting in delays and failures of delivery. protracted parturition due to maternal hypocalcemia was observed when rats were treated from before mating through gestation starting at 0.5 mg/kg/day (approximately one tenth the 40 mg clinical daily dose). maternotoxicity (late pregnancy deaths) also occurred in the female rats treated orally with 15 mg/kg/day (approximately 4 times the 40 mg clinical daily dose) for varying gestational time periods. these maternal deaths were lessened but not eliminated by cessation of treatment. calcium supplementation in the drinking water or by subcutaneous minipump to rats dosed orally with 15 mg/kg/day alendronate could not ameliorate the hypocalcemia or prevent the dystocia-related maternal and neonatal deaths. however, intravenous calcium supplementation prevented maternal, but not neonatal deaths. risk summary it is not known whether alendronate is present in human breast milk, affects human milk production, or has effects on the breastfed infant. the developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for alendronate sodium and any potential adverse effects on the breastfed child from alendronate sodium or from the underlying maternal condition. alendronate sodium is not indicated for use in pediatric patients. the safety and efficacy of alendronate sodium were examined in a randomized, double-blind, placebo-controlled two-year study of 139 pediatric patients, aged 4-18 years, with severe osteogenesis imperfecta (oi). one-hundred-and-nine patients were randomized to 5 mg alendronate sodium daily (weight less than 40 kg) or 10 mg alendronate sodium daily (weight greater than or equal to 40 kg) and 30 patients to placebo. the mean baseline lumbar spine bmd z-score of the patients was -4.5. the mean change in lumbar spine bmd z-score from baseline to month 24 was 1.3 in the alendronate sodium-treated patients and 0.1 in the placebo-treated patients. treatment with alendronate sodium did not reduce the risk of fracture. sixteen percent of the alendronate sodium patients who sustained a radiologically-confirmed fracture by month 12 of the study had delayed fracture healing (callus remodeling) or fracture non-union when assessed radiographically at month 24 compared with 9% of the placebo-treated patients. in alendronate sodium-treated patients, bone histomorphometry data obtained at month 24 demonstrated decreased bone turnover and delayed mineralization time; however, there were no mineralization defects. there were no statistically significant differences between the alendronate sodium and placebo groups in reduction of bone pain. the oral bioavailability in children was similar to that observed in adults. the overall safety profile of alendronate sodium in osteogenesis imperfecta patients treated for up to 24 months was generally similar to that of adults with osteoporosis treated with alendronate sodium. however, there was an increased occurrence of vomiting in osteogenesis imperfecta patients treated with alendronate sodium compared to placebo. during the 24-month treatment period, vomiting was observed in 32 of 109 (29.4%) patients treated with alendronate sodium and 3 of 30 (10%) patients treated with placebo. in a pharmacokinetic study, 6 of 24 pediatric osteogenesis imperfecta patients who received a single oral dose of alendronate sodium 35 or 70 mg developed fever, flu-like symptoms, and/or mild lymphocytopenia within 24 to 48 hours after administration. these events, lasting no more than 2 to 3 days and responding to acetaminophen, are consistent with an acute-phase response that has been reported in patients receiving bisphosphonates, including alendronate sodium. [see adverse reactions ( 6.2).] of the patients receiving alendronate sodium in the fracture intervention trial (fit), 71% (n=2302) were greater than or equal to 65 years of age and 17% (n=550) were greater than or equal to 75 years of age. of the patients receiving alendronate sodium in the united states and multinational osteoporosis treatment studies in women, osteoporosis studies in men, glucocorticoid-induced osteoporosis studies, and paget's disease studies [see clinical studies ( 14.1), ( 14.3), ( 14.4), ( 14.5)], 45%, 54%, 37%, and 70%, respectively, were 65 years of age or over. no overall differences in efficacy or safety were observed between these patients and younger patients, but greater sensitivity of some older individuals cannot be ruled out. alendronate sodium is not recommended for patients with creatinine clearance less than 35 ml/min . no dosage adjustment is necessary in patients with creatinine clearance values between 35-60 ml/min [see clinical pharmacology ( 12.3)] . as there is evidence that alendronate is not metabolized or excreted in the bile, no studies were conducted in patients with hepatic impairment. no dosage adjustment is necessary [see clinical pharmacology ( 12.3)] .
