Overdosage of VESIcare LS
Information about signs, symptoms, and laboratory findings of acute ovedosage and the general principles of overdose treatment.10 OVERDOSAGE Overdosage with VESIcare LS oral suspension can potentially result in severe antimuscarinic effects and should be treated accordingly. The highest dose ingested in an accidental overdose of solifenacin succinate was 280 mg (28 times the maximum dosage) in a 5-hour period in adults. This case was associated with mental status changes. Some cases reported a decrease in the level of consciousness. Intolerable antimuscarinic adverse reactions (fixed and dilated pupils, blurred vision, failure of heel-to-toe exam, tremors, and dry skin) occurred on day 3 in normal adult volunteers taking 50 mg daily (5 times the maximum recommended dosage) and resolved within 7 days following discontinuation of drug. The highest overdose reported in a pediatric patient was the accidental ingestion of 95 mg of solifenacin succinate (9.5 times the maximum recommended dosage). The child experienced severe antimuscarinic adverse reactions and was treated with gastric lavage and supportive measures until all antimuscarinic signs and symptoms reversed. In the event of overdose with VESIcare LS oral suspension, treat with gastric lavage and appropriate supportive measures. ECG monitoring is also recommended.
Adverse reactions
Information about undesirable effects, reasonably associated with use of the drug, that may occur as part of the pharmacological action of the drug or may be unpredictable in its occurrence. Adverse reactions include those that occur with the drug, and if applicable, with drugs in the same pharmacologically active and chemically related class. There is considerable variation in the listing of adverse reactions. They may be categorized by organ system, by severity of reaction, by frequency, by toxicological mechanism, or by a combination of these.6 ADVERSE REACTIONS • Angioedema and Anaphylactic Reactions [see Warnings and Precautions ( 5.1 )] • Urinary Retention [see Warnings and Precautions ( 5.2 )] • Gastrointestinal Disorders [see Warnings and Precautions ( 5.3 )] • Central Nervous System Effects [see Warnings and Precautions ( 5.4 )] • QT Prolongation in Patients at High Risk of QT Prolongation [see Warnings and Precautions ( 5.6 )] The most common adverse reactions (> 2%) were constipation, dry mouth and urinary tract infection. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Astellas Pharma US, Inc. at 1-800-727-7003 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 a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety of VESIcare LS oral suspension was evaluated in two open-label trials (Studies 1 and 2) [see Clinical Studies ( 14 )] . The two studies included 95 pediatric patients aged 2 to 17 years with neurogenic detrusor overactivity (NDO) who were 53% female, 58% White, 34% Asian and 2% Black. Treatment was initiated at the weight-based starting recommended dose and was titrated up or down in 2.5 mg increments over 12 weeks to the lowest effective dose (not to exceed the maximum recommended dose). Subsequent to the dose titration period, patients continued their optimized dose for a 40-week maintenance period (mean exposure duration 301 days, range 1 to 413 days). The most commonly reported adverse reactions were constipation, dry mouth, urinary tract infection, abdominal pain, urinalysis bacterial test positive, and somnolence. The incidence of adverse reactions was similar between patients taking the starting recommended dose and patients taking the maximum recommended dose with the exception of constipation, which was reported, in 8.5% of patients taking the maximum recommended dose compared to 0% of patients taking the starting recommended dose. Table 2 lists the adverse reactions reported in Studies 1 and 2 at an incidence equal to or greater than 1%. Table 2: Adverse Reactions Reported in ≥ 1% of Neurogenic Detrusor Overactivity (NDO) Patients Aged 2 to 17 Years Taking VESIcare LS Oral Suspension in Studies 1 and 2 Adverse Reaction Percentage (%) of Patients Reporting Adverse Reactions N=95 Constipation 7.4 Dry mouth 3.2 Urinary tract infection 2.1 Abdominal pain 1.1 Urinalysis bacterial test positive 1.1 Somnolence 1.1 Adverse reactions reported in ≥ 1% of solifenacin succinate-treated adult patients and at an incidence greater than in placebo-treated adult patients in clinical adult trials were: Gastrointestinal disorders : dry mouth, constipation, nausea, dyspepsia, upper abdominal pain, vomiting Infections and infestations : urinary tract infection, influenza, pharyngitis Nervous system disorders : dizziness Eye disorders : blurred vision, dry eyes Renal and urinary disorders : urinary retention General disorders and administration site conditions : lower limb edema, fatigue Psychiatric disorders : depression Respiratory, thoracic and mediastinal disorders : cough Vascular disorders : hypertension 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of solifenacin succinate. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. General disorders and administration site conditions : peripheral edema, hypersensitivity reactions (including angioedema with airway obstruction, rash, pruritus, urticaria, anaphylactic reaction); Nervous system disorders : dizziness, headache, confusion, hallucinations, delirium, somnolence; Cardiac disorders : QT prolongation, Torsade de Pointes, atrial fibrillation, tachycardia, palpitations; Hepatobiliary disorders : liver disorders mostly characterized by abnormal liver function tests, AST (aspartate aminotransferase), ALT (alanine aminotransferase), GGT (gamma-glutamyl transferase); Renal and urinary disorders : renal impairment, urinary retention; Metabolism and nutrition disorders : decreased appetite, hyperkalemia; Skin and subcutaneous tissue disorders : exfoliative dermatitis, erythema multiforme, dry skin; Eye disorders : glaucoma; Gastrointestinal disorders : gastroesophageal reflux disease, ileus, vomiting, abdominal pain, dysgeusia, sialadenitis; Respiratory, thoracic and mediastinal disorders : dysphonia, nasal dryness; Musculoskeletal and connective tissue disorders : muscular weakness.
VESIcare LS Drug Interactions
Information about and practical guidance on preventing clinically significant drug/drug and drug/food interactions that may occur in people taking the drug.7 DRUG INTERACTIONS CYP3A4 Inhibitors : Do not exceed the recommended starting dose of VESIcare LS with concomitant use of strong CYP3A4 inhibitors. ( 7.1 ) 7.1 Strong CYP3A4 Inhibitors Solifenacin is a substrate of CYP3A4. Concomitant use of ketoconazole, a strong CYP3A4 inhibitor, significantly increased the exposure of solifenacin [see Clinical Pharmacology ( 12.3 )] . The dosage of VESIcare LS greater than the starting dose is not recommended when concomitantly used with strong CYP3A4 inhibitors [see Dosage and Administration ( 2.4 )] .
Clinical pharmacology
Information about the clinical pharmacology and actions of the drug in humans.12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Solifenacin is a competitive muscarinic receptor antagonist. Muscarinic receptors play an important role in several major cholinergically mediated functions, including contractions of urinary bladder smooth muscle. 12.2 Pharmacodynamics Cardiac Electrophysiology The effect of 10 mg and 30 mg solifenacin succinate (three times the maximum recommended dose) on the QT interval was evaluated in adults at the time of peak plasma concentration of solifenacin in a multi-dose, randomized, double-blind, placebo and positive-controlled (moxifloxacin 400 mg) trial [see Warnings and Precautions ( 5.6 )]. After receiving placebo and moxifloxacin sequentially, adult subjects were randomized to one of two treatment groups. One group (n=51) completed 3 additional sequential periods of dosing with solifenacin succinate 10, 20, and 30 mg while the second group (n=25) in parallel completed a 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 a solifenacin exposure that covers those observed upon coadministration of 10 mg solifenacin succinate with strong CYP3A4 inhibitors (e.g., ketoconazole, 400 mg). Due to the sequential dose escalating nature of the study, baseline ECG 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 0 beats/minute, respectively. Because a 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 3 . Table 3: QTc changes in msec (90% CI) from baseline at T max (relative to placebo) in adults Results displayed are those derived from the parallel design portion of the study and represent the comparison of Group 1 to time-matched placebo effects in Group 2. Drug/Dose Fridericia Method (using mean difference) Solifenacin succinate 10 mg 2 (-3, 6) Solifenacin succinate 30 mg 8 (4, 13) Moxifloxacin was included as a positive control in this study and, given the length of the study, its effect on the QT interval was evaluated in 3 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 of the highest solifenacin succinate dose (three times the maximum therapeutic dose) studied was not as large as that of the positive control moxifloxacin at its recommended dose. However, the confidence intervals overlapped, and this study was not designed to draw direct statistical conclusions between the drugs or the dose levels. 12.3 Pharmacokinetics Absorption After oral administration of VESIcare LS in pediatric patients with neurogenic detrusor overactivity (NDO) aged 2 to 17 years, peak plasma concentrations (C max ) of solifenacin were reached within 2 to 6 hours after administration (t max ) and, at steady-state, the dose-normalized C max ranged from 2.5 - 29 ng/mL/mg. The absolute bioavailability of solifenacin in adults is approximately 90%, with plasma concentrations of solifenacin proportional to the dose administered. Effect of Food Food intake did not significantly affect the C max and AUC of solifenacin following oral administration of VESIcare LS. Distribution Solifenacin is approximately 98% ( in vivo ) bound to human plasma proteins, principally to α 1 -acid glycoprotein. Solifenacin is highly distributed to non-CNS tissues, having a median steady-state volume of distribution of 211 L in pediatric neurogenic detrusor overactivity (NDO) patients from 2 to 17 years old. Elimination The median elimination half-life of solifenacin is approximately 26 hours in pediatric neurogenic detrusor overactivity (NDO) patients 2 years of age and older. Metabolism Solifenacin 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 the 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. Excretion Following the administration of 10 mg of 14 C-solifenacin succinate to healthy adult volunteers, 69% of the radioactivity was recovered in the urine and 23% 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. Specific Populations Patients with Renal Impairment In studies with solifenacin succinate 10 mg in adults, there was a 2.1-fold increase in AUC and a 1.6-fold increase in t 1/2 of solifenacin in patients with severe renal impairment compared to subjects with normal renal function [see Use in Specific Populations ( 8.6 )] . Patients with Hepatic Impairment In studies with solifenacin succinate 10 mg in adults, there was a 2-fold increase in the t 1/2 and a 35% increase in AUC of solifenacin in patients with moderate hepatic impairment compared to subjects with normal hepatic function [see Use in Specific Populations ( 8.7 )] . Solifenacin succinate has not been studied in patients with severe hepatic impairment. Drug Interaction Studies Interaction studies have only been performed in adults. In pediatric patients 2 years of age and older, metabolism via CYP3A4 is the major route of elimination and the metabolic capacity of the liver is similar. Strong CYP3A4 Inhibitors In a crossover study in adults, following blockade of CYP3A4 by coadministration of the strong CYP3A4 inhibitor, ketoconazole 400 mg once daily for 21 days, the mean C 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 )] . CYP3A4 Inducers Because solifenacin is a substrate of CYP3A4, inducers of CYP3A4 may decrease the concentration of solifenacin. Warfarin In a crossover study in adults, subjects received a single oral dose of warfarin 25 mg on the 10 th day of dosing with either solifenacin succinate 10 mg or matching placebo once daily for 16 days. For R -warfarin, when it was coadministered with solifenacin succinate, the mean C max increased by 3% and AUC decreased by 2%. For S -warfarin, when it was coadministered with solifenacin succinate, the mean C max and AUC increased by 5% and 1%, respectively. Oral Contraceptives In a crossover study in adults, subjects received 2 cycles of 21 days of oral contraceptives containing 30 ug ethinyl estradiol and 150 ug levonorgestrel. During the second cycle, subjects received additional solifenacin succinate 10 mg or matching placebo once daily for 10 days starting from the 12 th day of receipt of oral contraceptives. For ethinyl estradiol, when it was administered with solifenacin succinate, the mean C max and AUC increased by 2% and 3%, respectively. For levonorgestrel, when it was administered with solifenacin succinate, the mean C max and AUC decreased by 1%. Digoxin In a crossover study in adults, subjects received digoxin (loading dose of 0.25 mg on day 1, followed by 0.125 mg from days 2 to 8) for 8 days. Consecutively, they received solifenacin succinate 10 mg or matching placebo with digoxin 0.125 mg for an additional 10 days. When digoxin was coadministered with solifenacin succinate, the mean C max and AUC increased by 13% and 4%, respectively. Drugs Metabolized by Cytochrome P450 Enzymes In vitro studies demonstrated that, at therapeutic concentrations, solifenacin does not inhibit CYP1A1/2, 2C9, 2C19, 2D6, or 3A4 derived from human liver microsomes.

Most labels do not contain this field.13.2 Animal Toxicology and/or Pharmacology Juvenile Animal Toxicology Data Dose-related increased mortality without preceding clinical signs occurred in juvenile mice treated before weaning for a duration of 12 weeks, from day 10 after birth, with doses that achieved a pharmacological effect. Animals dosed from postnatal day 10 onwards had higher mortality compared to the mortality in adult mice. No increased frequency in mortality was observed in juvenile mice that were treated after weaning for a duration of 4 weeks, from day 21 after birth onwards. Plasma exposure at postnatal day 10 was higher than in adult mice; the systemic exposure at postnatal day 21 was comparable to the systemic exposure in adult mice.
Carcinogenesis and mutagenesis and impairment of fertility
Information about carcinogenic, mutagenic, or fertility impairment potential revealed by studies in animals. Information from human data about such potential is part of the warnings field.13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility No increase in tumors was found following the administration of solifenacin succinate to male and female mice for 104 weeks at doses up to 200 mg/kg/day (5 and 9 times, respectively, of the exposure at the maximum recommended human dose [MRHD] of 10 mg), and male and female rats for 104 weeks at doses up to 20 and 15 mg/kg/day, respectively (< 1 times the exposure at the MRHD). Solifenacin succinate was not mutagenic in the in vitro Salmonella typhimurium or Escherichia coli microbial mutagenicity test or chromosomal aberration test in human peripheral blood lymphocytes with or without metabolic activation or in the in vivo micronucleus test in rats. Solifenacin succinate had no effect on reproductive function, fertility, or early embryonic development of the fetus in male and female mice treated with 250 mg/kg/day (13 times the exposure at the MRHD) of solifenacin succinate, and in male rats treated with 50 mg/kg/day (< 1 times the exposure at the MRHD) and female rats treated with 100 mg/kg/day (1.7 times the exposure at the MRHD) of solifenacin succinate.

Clinical studies
This field may contain references to clinical studies in place of detailed discussion in other sections of the labeling.14 CLINICAL STUDIES The efficacy of VESIcare LS oral suspension was evaluated in two 52-week, open-label, baseline-controlled, sequential dose titration studies in a total of 95 pediatric patients 2 years of age and older with neurogenic detrusor overactivity (NDO). Study 1 (NCT01981954) included patients 2 to less than 5 years of age and Study 2 (NCT01565694) included patients 5 to 17 years of age. Entry criteria required that patients had a diagnosis of neurogenic detrusor overactivity (NDO) confirmed by urodynamics demonstrating the presence of involuntary detrusor contractions with detrusor pressure increase greater than 15 cm H 2 O and that patients or their caregivers practiced clean intermittent catheterization (CIC). VESIcare LS oral suspension was administered once daily. All patients initially received a weight-based starting dose, followed by dose titration to their lowest effective dose, up to a maximum dose. The duration of the dose titration period was up to 12 weeks and this period was followed by a dose maintenance period of at least 40 weeks. In Study 1, a total of 19 patients aged 2 to less than 5 years of age received VESIcare LS oral suspension. Of these, 17 patients completed treatment through week 24 and had adequate urodynamic measurements for evaluation of efficacy. The optimized maintenance dose within this study population included 63% of patients at the maximum dose, 26% of patients at an intermediate dose, and 5% of patients at the starting dose. The study population included 7 males (41%) and 10 females (59%). In Study 2, a total of 76 patients aged 5 to 17 years of age received VESIcare LS oral suspension. Of these, 49 patients (24 patients aged 5 to < 12 years and 25 patients aged 12 to 17 years) completed treatment through week 24 and had adequate urodynamic measurements for evaluation of efficacy. The optimized maintenance dose within this study population included 58% of patients at the maximum dose, 15% of patients at an intermediate dose, and 7% of patients at the starting dose. This study population included 24 males (49%) and 25 females (51%). The primary efficacy endpoint was change from baseline in the patients’ maximum cystometric (bladder) capacity (MCC) after 24 weeks of treatment with VESIcare LS oral suspension. As shown in Table 4, an improvement in MCC was observed in patients aged 2 to less than 5 years of age and in patients aged 5 to 17 years of age. The magnitude of the observed changes from baseline in the primary and secondary efficacy endpoints were comparable between patients 5 to less than 12 years of age and patients 12 to 17 years of age. The results for the primary efficacy endpoint in the 2 clinical studies of VESIcare LS oral suspension in pediatric patients with neurogenic detrusor overactivity (NDO) are shown in Table 4 . Treatment effects were maintained over 52 weeks.

Pediatric use
Information about any limitations on any pediatric indications, needs for specific monitoring, hazards associated with use of the drug in any subsets of the pediatric population (such as neonates, infants, children, or adolescents), differences between pediatric and adult responses to the drug, and other information related to the safe and effective pediatric use of the drug.8.4 Pediatric Use The safety and effectiveness of VESIcare LS have been established in pediatric patients aged 2 years and older for the treatment of neurogenic detrusor overactivity (NDO) and the information on this use is discussed throughout the labeling. The safety and effectiveness of VESIcare LS have not been established in pediatric patients less than 2 years of age.
Pregnancy
Information about effects the drug may have on pregnant women or on a fetus. This field may be ommitted if the drug is not absorbed systemically and the drug is not known to have a potential for indirect harm to the fetus. It may contain information about the established pregnancy category classification for the drug. (That information is nominally listed in the teratogenic_effects field, but may be listed here instead.)8.1 Pregnancy Risk Summary There are no studies with the use of solifenacin succinate in pregnant women or adolescents to inform a drug-associated risk of major birth defects, miscarriages, or adverse maternal or fetal outcomes. No adverse developmental outcomes were observed in animal reproduction studies with oral administration of solifenacin succinate to pregnant mice during the period of organogenesis at a dose resulting in 1.2 times the systemic exposure at the maximum recommended human dose (MRHD) of 10 mg/day. However, administration of doses 3.6 times and greater than the MRHD during organogenesis produced maternal toxicity in the pregnant mice and resulted in developmental toxicity and reduced fetal body weights in offspring [see Data ] . In the U.S. general population, the estimated background risk of major birth defects or miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Data Animal Data Oral administration of 14 C-solifenacin succinate to pregnant mice resulted in the recovery of radiolabel in the fetus indicating that solifenacin-related product can cross the placental barrier. In pregnant mice, administration of solifenacin succinate at a dose of 250 mg/kg/day (7.9 times the systemic exposure at the MRHD of 10 mg), resulted in an increased incidence of cleft palate and increased maternal lethality. Administration of solifenacin succinate to pregnant mice during organogenesis at greater than or equal to 3.6 times (100 mg/kg/day and greater) the systemic exposure at the MRHD, resulted in reduced fetal body weights and reduced maternal body weight gain. No embryo-fetal toxicity or teratogenicity was observed in fetuses from pregnant mice treated with solifenacin succinate at a dose of 30 mg/kg/day (1.2 times the systemic exposure at the MRHD). Administration of solifenacin succinate to pregnant rats and rabbits at a dose of 50 mg/kg/day (< 1 times and 1.8 times the systemic exposure at the MRHD, respectively), resulted in no findings of embryo-fetal toxicity. Oral pre- and post-natal administration of solifenacin succinate at 100 mg/kg/day (3.6 times the systemic exposure at the MRHD) during the period of organogenesis through weaning, resulted in reduced peripartum and postnatal survival, reduced body weight gain by the pups, and delayed physical development (eye opening and vaginal patency). An increase in the percentage of male offspring was also observed in litters from offspring (F2 generation) exposed to maternal doses of 250 mg/kg/day. There were no effects on natural delivery in mice treated with 1.2 times (30 mg/kg/day) the expected systemic exposure at the MRHD.
Use in specific populations
Information about use of the drug by patients in specific populations, including pregnant women and nursing mothers, pediatric patients, and geriatric patients.8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Risk Summary There are no studies with the use of solifenacin succinate in pregnant women or adolescents to inform a drug-associated risk of major birth defects, miscarriages, or adverse maternal or fetal outcomes. No adverse developmental outcomes were observed in animal reproduction studies with oral administration of solifenacin succinate to pregnant mice during the period of organogenesis at a dose resulting in 1.2 times the systemic exposure at the maximum recommended human dose (MRHD) of 10 mg/day. However, administration of doses 3.6 times and greater than the MRHD during organogenesis produced maternal toxicity in the pregnant mice and resulted in developmental toxicity and reduced fetal body weights in offspring [see Data ] . In the U.S. general population, the estimated background risk of major birth defects or miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Data Animal Data Oral administration of 14 C-solifenacin succinate to pregnant mice resulted in the recovery of radiolabel in the fetus indicating that solifenacin-related product can cross the placental barrier. In pregnant mice, administration of solifenacin succinate at a dose of 250 mg/kg/day (7.9 times the systemic exposure at the MRHD of 10 mg), resulted in an increased incidence of cleft palate and increased maternal lethality. Administration of solifenacin succinate to pregnant mice during organogenesis at greater than or equal to 3.6 times (100 mg/kg/day and greater) the systemic exposure at the MRHD, resulted in reduced fetal body weights and reduced maternal body weight gain. No embryo-fetal toxicity or teratogenicity was observed in fetuses from pregnant mice treated with solifenacin succinate at a dose of 30 mg/kg/day (1.2 times the systemic exposure at the MRHD). Administration of solifenacin succinate to pregnant rats and rabbits at a dose of 50 mg/kg/day (< 1 times and 1.8 times the systemic exposure at the MRHD, respectively), resulted in no findings of embryo-fetal toxicity. Oral pre- and post-natal administration of solifenacin succinate at 100 mg/kg/day (3.6 times the systemic exposure at the MRHD) during the period of organogenesis through weaning, resulted in reduced peripartum and postnatal survival, reduced body weight gain by the pups, and delayed physical development (eye opening and vaginal patency). An increase in the percentage of male offspring was also observed in litters from offspring (F2 generation) exposed to maternal doses of 250 mg/kg/day. There were no effects on natural delivery in mice treated with 1.2 times (30 mg/kg/day) the expected systemic exposure at the MRHD. 8.2 Lactation Risk Summary There is no information on the presence of solifenacin in human milk, the effects on the breastfed child, or the effects on milk production. Solifenacin is present in mouse milk [see Data ] . When a drug is present in animal milk, it is likely that the drug will be present in human milk. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for VESIcare LS and any potential adverse effects on the breastfed child from VESIcare LS or from the underlying maternal condition. Data Animal Data Oral administration of 14 C-solifenacin succinate to lactating mice resulted in the recovery of radioactivity in maternal milk. Lactating female mice orally administered solifenacin succinate at a maternally toxic dose of 100 mg/kg/day (3.6 times the systemic exposure at the MRHD) had increased postpartum pup mortality, pups with reduced body weights, or delays in the onset of reflex and physical development. Pups from lactating dams orally administered solifenacin succinate at a dose of 30 mg/kg/day (1.2 times the systemic exposure at the MRHD) had no discernible adverse findings. The concentrations of solifenacin in animal milk does not necessarily predict the concentration of drug in human milk. 8.4 Pediatric Use The safety and effectiveness of VESIcare LS have been established in pediatric patients aged 2 years and older for the treatment of neurogenic detrusor overactivity (NDO) and the information on this use is discussed throughout the labeling. The safety and effectiveness of VESIcare LS have not been established in pediatric patients less than 2 years of age. 8.6 Renal Impairment Solifenacin plasma concentrations are greater in adults with severe renal impairment compared to adults with normal renal function [see Clinical Pharmacology ( 12.3 )] . Because increased solifenacin plasma concentrations increase the risk of antimuscarinic adverse reactions, the maximum recommended dose of VESIcare LS oral suspension in pediatric patients 2 years of age and older with severe renal impairment (CL cr < 30 mL/min/1.73 m 2 ) is the starting dose [see Dosage and Administration ( 2.2 )] . The recommended dose in patients with mild or moderate renal impairment is the same as in patients with normal renal function. 8.7 Hepatic Impairment Solifenacin plasma concentrations are greater in adults with moderate hepatic impairment compared to adults with normal hepatic function [see Clinical Pharmacology ( 12.3 )] . Because increased solifenacin plasma concentrations increase the risk of antimuscarinic adverse reactions, the maximum recommended dose of VESIcare LS oral suspension in pediatric patients 2 years of age and older with moderate hepatic impairment (Child-Pugh B) is the starting dose [see Dosage and Administration ( 2.3 )] and VESIcare LS oral suspension is not recommended for use in patients with severe hepatic impairment (Child-Pugh C).
