ADVERSE REACTIONS SECTION.

6 ADVERSE REACTIONS. The most common adverse reactions (> 4% and placebo) were dry mouth, and constipation at both mg and 10 mg doses; and urinary tract infection, and blurred vision at the 10 mg dose 6.1) To report SUSPECTED ADVERSE REACTIONS, contact AvKARE at 1-855-361-3993 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.. 6.1 Clinical Trials Experience. Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.Solifenacin has been evaluated for safety in 1811 patients in randomized, placebo-controlled trials. Expected adverse reactions of antimuscarinic agents are dry mouth, constipation, blurred vision (accommodation abnormalities), urinary retention, and dry eyes. The incidence of dry mouth and constipation in patients treated with Solifenacin was higher in the 10 mg compared to the mg dose group.In the four 12-week double-blind clinical trials, severe fecal impaction, colonic obstruction, and intestinal obstruction were reported in one patient each, all in the Solifenacin 10 mg group. Angioneurotic edema has been reported in one patient taking Solifenacin mg. Compared to 12 weeks of treatment with Solifenacin, the incidence and severity of adverse reactions were similar in patients who remained on drug for up to 12 months.The most frequent adverse reaction leading to study discontinuation was dry mouth (1.5%). Table lists the rates of identified adverse reactions, derived from all reported adverse events, in randomized, placebo-controlled trials at an incidence greater than placebo and in 1% or more of patients treated with Solifenacin or 10 mg once daily for up to 12 weeks.Table 1.

CLINICAL PHARMACOLOGY SECTION.

12 CLINICAL PHARMACOLOGY. 12.1 Mechanism of Action. Solifenacin is competitive muscarinic receptor antagonist. Muscarinic receptors play an important role in several major cholinergically mediated functions, including contractions of urinary bladder smooth muscle and stimulation of salivary secretion.. 12.2 Pharmacodynamics. Cardiac ElectrophysiologyThe effect of 10 mg and 30 mg solifenacin succinate on the QT interval was evaluated at the time of peak plasma concentration of solifenacin in multi-dose, randomized, double-blind, placebo and positive-controlled (moxifloxacin 400 mg) trial. Subjects were randomized to one of two treatment groups after receiving placebo and moxifloxacin sequentially. One group (n=51) went on to complete additional sequential periods of dosing with solifenacin 10, 20, and 30 mg while the second group (n=25) in parallel completed sequence of placebo and moxifloxacin. Study subjects were female volunteers aged 19 to 79 years. The 30 mg dose of solifenacin succinate (three times the highest recommended dose) was chosen for use in this study because this dose results in solifenacin exposure that covers those observed upon co-administration of 10 mg Solifenacin Succinate Tablets with potent CYP3A4 inhibitors (e.g. ketoconazole, 400 mg). Due to the sequential dose escalating nature of the study, baseline EKG measurements were separated from the final QT assessment (of the 30 mg dose level) by 33 days.The median difference from baseline in heart rate associated with the 10 and 30 mg doses of solifenacin succinate compared to placebo was -2 and beats/minute, respectively. Because significant period effect on QTc was observed, the QTc effects were analyzed utilizing the parallel placebo control arm rather than the pre-specified intra-patient analysis. Representative results are shown in Table 2.Table 2. QTc changes in msec (90%CI) from baseline at Tmax (relative to placebo) Drug/Dose Fridericia method (using mean difference) Solifenacin 10 mg (-3,6) Solifenacin 30 mg (4,13)Results displayed are those derived from the parallel design portion of the study and represent the comparison of Group to time-matched placebo effects in Group 2Moxifloxacin was included as positive control in this study and, given the length of the study, its effect on the QT interval was evaluated in different sessions. The placebo subtracted mean changes (90% CI) in QTcF for moxifloxacin in the three sessions were 11 (7, 14), 12 (8, 17), and 16 (12, 21), respectively.The QT interval prolonging effect appeared greater for the 30 mg compared to the 10 mg dose of solifenacin. Although the effect of the highest solifenacin dose (three times the maximum therapeutic dose) studied did not appear as large as that of the positive control moxifloxacin at its therapeutic dose, the confidence intervals overlapped. This study was not designed to draw direct statistical conclusions between the drugs or the dose levels.. 12.3 Pharmacokinetics. AbsorptionAfter oral administration of Solifenacin to healthy volunteers, peak plasma levels (C max) of solifenacin are reached within to hours after administration, and at steady state ranged from 32.3 to 62.9 ng/mL for the and 10 mg Solifenacin, respectively. The absolute bioavailability of solifenacin is approximately 90%, and plasma concentrations of solifenacin are proportional to the dose administered. Effect of foodSolifenacin may be administered without regard to meals. single 10 mg dose administration of Solifenacin with food increased max and AUC by 4% and 3%, respectively. DistributionSolifenacin is approximately 98% in vivo) bound to human plasma proteins, principally to 1-acid glycoprotein. Solifenacin is highly distributed to non-CNS tissues, having mean steady-state volume of distribution of 600L. MetabolismSolifenacin is extensively metabolized in the liver. The primary pathway for elimination is by way of CYP3A4; however, alternate metabolic pathways exist. The primary metabolic routes of solifenacin are through N-oxidation of the quinuclidin ring and 4R-hydroxylation of tetrahydroisoquinoline ring. One pharmacologically active metabolite (4R-hydroxy solifenacin), occurring at low concentrations and unlikely to contribute significantly to clinical activity, and three pharmacologically inactive metabolites (N-glucuronide and the N-oxide and 4R-hydroxy-N-oxide of solifenacin) have been found in human plasma after oral dosing.. ExcretionFollowing the administration of 10 mg of 14C-solifenacin succinate to healthy volunteers, 69.2% of the radioactivity was recovered in the urine and 22.5% in the feces over 26 days. Less than 15% (as mean value) of the dose was recovered in the urine as intact solifenacin. The major metabolites identified in urine were N-oxide of solifenacin, 4R-hydroxy solifenacin and 4R-hydroxy-N-oxide of solifenacin and in feces 4R-hydroxy solifenacin. The elimination half-life of solifenacin following chronic dosing is approximately 45-68 hours. Drug Interactions. Potent CYP3A4 InhibitorsIn crossover study, following blockade of CYP3A4 by coadministration of the potent CYP3A4 inhibitor, ketoconazole 400 mg, once daily for 21 days, the mean max and AUC of solifenacin increased by 1.5 and 2.7-fold, respectively see Dosage and Administration 2.4) and Drug Interactions 7.1) ]. WarfarinIn crossover study, subjects received single oral dose of warfarin 25 mg on the 10 th day of dosing with either solifenacin 10 mg or matching placebo once daily for 16 days. For R-warfarin when it was coadministered with solifenacin, the mean max increased by 3% and AUC decreased by 2%. For S-warfarin when it was coadministered with solifenacin, the mean max and AUC increased by 5% and 1%, respectively see Drug Interactions 7.4) ]. Oral ContraceptivesIn crossover study, subjects received cycles of 21 days of oral contraceptives containing 30 ug ethinyl estradiol and 150 ug levonorgestrel. During the second cycle, subjects received additional solifenacin 10 mg or matching placebo once daily for 10 days starting from 12 th day of receipt of oral contraceptives. For ethinyl estradiol when it was administered with solifenacin, the mean max and AUC increased by 2% and 3%, respectively. For levonorgestrel when it was administered with solifenacin, the mean max and AUC decreased by 1% see Drug Interactions 7.5) ]. DigoxinIn crossover study, subjects received digoxin (loading dose of 0.25 mg on day 1, followed by 0.125 mg from days to 8) for days. Consecutively, they received solifenacin 10 mg or matching placebo with digoxin 0.125 mg for additional 10 days. When digoxin was coadministered with solifenacin, the mean max and AUC increased by 13% and 4%, respectively see Drug Interactions 7.6) ].

CLINICAL STUDIES SECTION.

14 CLINICAL STUDIES. Solifenacin was evaluated in four twelve-week, double-blind, randomized, placebo-controlled, parallel group, multicenter clinical trials for the treatment of overactive bladder in patients having symptoms of urinary frequency, urgency, and/or urge or mixed incontinence (with predominance of urge). Entry criteria required that patients have symptoms of overactive bladder for >= months duration. These studies involved 3027 patients (1811 on Solifenacin and 1216 on placebo), and approximately 90% of these patients completed the 12-week studies. Two of the four studies evaluated the and 10 mg Solifenacin doses and the other two evaluated only the 10 mg dose. All patients completing the 12-week studies were eligible to enter an open label, long term extension study and 81% of patients enrolling completed the additional 40-week treatment period. The majority of patients were Caucasian (93%) and female (80%) with mean age of 58 years.The primary endpoint in all four trials was the mean change from baseline to 12 weeks in number of micturitions/24 hours. Secondary endpoints included mean change from baseline to 12 weeks in number of incontinence episodes/24 hours, and mean volume voided per micturition. The efficacy of Solifenacin was similar across patient age and gender. The mean reduction in the number of micturitions per 24 hours was significantly greater with Solifenacin mg (2.3; p<0.001) and Solifenacin 10 mg (2.7; p<0.001) compared to placebo, (1.4).The mean reduction in the number of incontinence episodes per 24 hours was significantly greater with Solifenacin mg (1.5; p<0.001) and Solifenacin 10 mg (1.8; p<0.001) treatment groups compared to placebo (1.1). The mean increase in the volume voided per micturition was significantly greater with Solifenacin mg (32.3 mL; p<0.001) and Solifenacin 10 mg (42.5 mL; p<0.001) compared with placebo (8.5 mL).The results for the primary and secondary endpoints in the four individual 12-week clinical studies of Solifenacin are reported in Tables through 6.Table 3.

DRUG INTERACTIONS SECTION.

7 DRUG INTERACTIONS. Inhibitors of CYP3A4 may increase the concentration of Solifenacin 7.1). Inducers of CYP3A4 may decrease the concentration of Solifenacin 7.2). Inhibitors of CYP3A4 may increase the concentration of Solifenacin 7.1). Inducers of CYP3A4 may decrease the concentration of Solifenacin 7.2). 7.1 Potent CYP3A4 Inhibitors. Following the administration of 10 mg of Solifenacin in presence of 400 mg of ketoconazole, potent inhibitor of CYP3A4, the mean max and AUC of solifenacin increased by 1.5 and 2.7-fold, respectively. Therefore, it is recommended not to exceed 5 mg daily dose of Solifenacin when administered with therapeutic doses of ketoconazole or other potent CYP3A4 inhibitors see Dosage and Administration 2.4) and Clinical Pharmacology 12.3) ]. The effects of weak or moderate CYP3A4 inhibitors were not examined. 7.2 CYP3A4 Inducers. There were no in vivo studies conducted to evaluate the effect of CYP3A4 inducers on Solifenacin. In vitro drug metabolism studies have shown that solifenacin is substrate of CYP3A4. Therefore, inducers of CYP3A4 may decrease the concentration of solifenacin.. 7.3 Drugs Metabolized by Cytochrome P450.

USE IN SPECIFIC POPULATIONS SECTION.

8 USE IN SPECIFIC POPULATIONS. Pregnancy and Nursing Mothers: Solifenacin Succinate Tablets should be used during pregnancy only if the potential benefit for the mother justifies the potential risk to the fetus. Solifenacin Succinate Tablets should not be administered during nursing 8.1, 8.3) Pediatric Use: The safety and effectiveness of Solifenacin Succinate Tablets in pediatric patients have not been established 8.4) 8.1 Pregnancy. Pregnancy Category CThere are no adequate and well-controlled studies in pregnant women.Reproduction studies have been performed in mice, rats and rabbits. After oral administration of 14C-solifenacin succinate to pregnant mice, drug-related material was shown to cross the placental barrier. No embryotoxicity or teratogenicity was observed in mice treated with 1.2 times (30 mg/kg/day) the expected exposure at the maximum recommended human dose [MRHD] of 10 mg. Administration of solifenacin succinate to pregnant mice at 3.6 times and greater (100 mg/kg/day and greater) the exposure at the MRHD, during the major period of organ development resulted in reduced fetal body weights. Administration of 7.9 times (250 mg/kg/day) the MRHD to pregnant mice resulted in an increased incidence of cleft palate. In utero and lactational exposures to maternal doses of solifenacin succinate of 3.6 times (100 mg/kg/day) the MRHD resulted in reduced peripartum and postnatal survival, reductions in body weight gain, and delayed physical development (eye opening and vaginal patency). An increase in the percentage of male offspring was also observed in litters from offspring exposed to maternal doses of 250 mg/kg/day. No embryotoxic effects were observed in rats at up to 50 mg/kg/day (<1 times the exposure at the MRHD) or in rabbits at up to 1.8 times (50 mg/kg/day) the exposure at the MRHD. Because animal reproduction studies are not always predictive of human response, Solifenacin should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. 8.2 Labor and Delivery. The effect of Solifenacin on labor and delivery in humans has not been studied.There were no effects on natural delivery in mice treated with 1.2 times (30 mg/kg/day) the expected exposure at the maximum recommended human dose [MRHD] of 10 mg. Administration of solifenacin succinate at 3.6 times (100 mg/kg/day) the exposure at the MRHD or greater increased peripartum pup mortality.. 8.3 Nursing Mothers. After oral administration of 14C-solifenacin succinate to lactating mice, radioactivity was detected in maternal milk. There were no adverse observations in mice treated with 1.2 times (30 mg/kg/day) the expected exposure at the maximum recommended human dose [MRHD]. Pups of female mice treated with 3.6 times (100 mg/kg/day) the exposure at the MRHD or greater revealed reduced body weights, postpartum pup mortality or delays in the onset of reflex and physical development during the lactation period. It is not known whether solifenacin is excreted in human milk. Because many drugs are excreted in human milk, Solifenacin should not be administered during nursing. decision should be made whether to discontinue nursing or to discontinue Solifenacin in nursing mothers.. 8.4 Pediatric Use. The safety and effectiveness of Solifenacin in pediatric patients have not been established.. 8.5 Geriatric Use. In placebo-controlled clinical studies, similar safety and effectiveness were observed between older (623 patients >= 65 years and 189 patients >= 75 years) and younger patients (1188 patients 65 years) treated with Solifenacin.Multiple dose studies of Solifenacin in elderly volunteers (65 to 80 years) showed that max, AUC and 1/2 values were 20-25% higher as compared to the younger volunteers (18 to 55 years). 8.6 Renal Impairment. Solifenacin should be used with caution in patients with renal impairment. There is 2.1-fold increase in AUC and 1.6-fold increase in 1/2 of solifenacin in patients with severe renal impairment. Doses of Solifenacin greater than mg are not recommended in patients with severe renal impairment (CL cr 30 mL/min) see Warnings and Precautions 5.7); Dosage and Administration 2.2) ]. 8.7 Hepatic Impairment. Solifenacin should be used with caution in patients with reduced hepatic function. There is 2-fold increase in the 1/2 and 35% increase in AUC of solifenacin in patients with moderate hepatic impairment. Doses of Solifenacin greater than mg are not recommended in patients with moderate hepatic impairment (Child-Pugh B). Solifenacin is not recommended for patients with severe hepatic impairment (Child-Pugh C) see Warnings and Precautions 5.6); Dosage and Administration 2.3) ]. 8.8 Gender. The pharmacokinetics of solifenacin is not significantly influenced by gender.

WARNINGS AND PRECAUTIONS SECTION.

5 WARNINGS AND PRECAUTIONS. Angioedema and anaphylactic reactions: Reports of angioedema of the face, lips and/or larynx, in some cases occurring after the first dose, have been described. Anaphylactic reactions have been reported rarely 5.1) Urinary Retention: Administer with caution to patients with clinically significant bladder outflow obstruction 5.2) Gastrointestinal Disorders: Use with caution in patients with decreased gastrointestinal motility 5.3) Central Nervous System Effects: Somnolence has been reported with Solifenacin. Advise patients not to drive or operate heavy machinery until they know how Solifenacin affects them 5.4) Controlled Narrow-Angle Glaucoma: Use with caution in patients being treated for narrow-angle glaucoma 5.5) QT Prolongation: Use with caution in patients with known history of QT prolongation or patients who are taking medications known to prolong the QT interval 5.8) Angioedema and anaphylactic reactions: Reports of angioedema of the face, lips and/or larynx, in some cases occurring after the first dose, have been described. Anaphylactic reactions have been reported rarely 5.1) Urinary Retention: Administer with caution to patients with clinically significant bladder outflow obstruction 5.2) Gastrointestinal Disorders: Use with caution in patients with decreased gastrointestinal motility 5.3) Central Nervous System Effects: Somnolence has been reported with Solifenacin. Advise patients not to drive or operate heavy machinery until they know how Solifenacin affects them 5.4) Controlled Narrow-Angle Glaucoma: Use with caution in patients being treated for narrow-angle glaucoma 5.5) QT Prolongation: Use with caution in patients with known history of QT prolongation or patients who are taking medications known to prolong the QT interval 5.8) 5.1 Angioedema and Anaphylactic Reactions. Angioedema of the face, lips, tongue, and/or larynx have been reported with solifenacin. In some cases angioedema occurred after the first dose. Cases of angioedema have been reported to occur hours after the first dose or after multiple doses. Angioedema associated with upper airway swelling may be life threatening. If involvement of the tongue, hypopharynx, or larynx occurs, solifenacin should be promptly discontinued and appropriate therapy and/or measures necessary to ensure patent airway should be promptly provided. Anaphylactic reactions have been reported rarely in patients treated with solifenacin succinate. Solifenacin succinate should not be used in patients with known or suspected hypersensitivity to solifenacin succinate. In patients who develop anaphylactic reactions, solifenacin succinate should be discontinued and appropriate therapy and/or measures should be taken.. 5.2 Urinary Retention. Solifenacin, like other anticholinergic drugs, should be administered with caution to patients with clinically significant bladder outflow obstruction because of the risk of urinary retention see Contraindications 4) ]. 5.3 Gastrointestinal Disorders. Solifenacin, like other anticholinergics, should be used with caution in patients with decreased gastrointestinal motility see Contraindications 4) ]. 5.4 Central Nervous System Effects. Solifenacin is associated with anticholinergic central nervous system (CNS) effects see Adverse Reactions 6.2) ]. variety of CNS anticholinergic effects have been reported, including headache, confusion, hallucinations and somnolence. Patients should be monitored for signs of anticholinergic CNS effects, particularly after beginning treatment or increasing the dose. Advise patients not to drive or operate heavy machinery until they know how Solifenacin Succinate Tablets affects them. If patient experiences anticholinergic CNS effects, dose reduction or drug discontinuation should be considered. 5.5 Controlled Narrow-Angle Glaucoma. Solifenacin should be used with caution in patients being treated for narrow-angle glaucoma see Contraindications 4) ]. 5.6 Hepatic Impairment. Solifenacin should be used with caution in patients with hepatic impairment. Doses of Solifenacin greater than mg are not recommended in patients with moderate hepatic impairment (Child-Pugh B). Solifenacin is not recommended for patients with severe hepatic impairment (Child-Pugh C) see Dosage and Administration 2.3) and Use in Specific Populations 8.7) ]. 5.7 Renal Impairment. Solifenacin should be used with caution in patients with renal impairment. Doses of Solifenacin greater than mg are not recommended in patients with severe renal impairment (CL cr <30 mL/min) see Dosage and Administration 2.2) and Use in Specific Populations 8.6) ]. 5.8 Patients with Congenital or Acquired QT Prolongation. In study of the effect of solifenacin on the QT interval in 76 healthy women see Clinical Pharmacology 12.2) the QT prolonging effect appeared less with solifenacin 10 mg than with 30 mg (three times the maximum recommended dose), and the effect of solifenacin 30 mg did not appear as large as that of the positive control moxifloxacin at its therapeutic dose. This observation should be considered in clinical decisions to prescribe Solifenacin for patients with known history of QT prolongation or patients who are taking medications known to prolong the QT interval.
