ADVERSE REACTIONS SECTION
6 ADVERSE REACTIONS
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.
Solifenacin succinate has been evaluated for safety in 1811 adult patients in
four randomized, placebo-controlled trials (Studies 1-4) [see Clinical Studies (14)]. 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 succinate was higher in the 10 mg dose group compared to the
5 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 succinate 10 mg group. Angioneurotic edema was
reported in one patient taking solifenacin succinate 5 mg. Compared to 12
weeks of treatment with solifenacin succinate, the incidence and severity of
adverse reactions were similar in patients who remained on drug for up to 12
months in Study 5 [see Clinical Studies (14)].
The most frequent adverse reaction leading to study discontinuation was dry
mouth (1.5%). Table 1 lists the rates of identified adverse reactions, in the
four randomized, placebo-controlled trials at an incidence greater than
placebo and in 1% or more of patients treated with solifenacin succinate 5 or
10 mg once daily for up to 12 weeks.

6.2 Postmarketing Experience
The following adverse reactions have been identified during post-approval use
of solifenacin succinate in the U.S. and/or outside of the U.S. 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.
The most common adverse reactions (> 4% in solifenacin succinate-treated patients and > placebo-treated patients) were dry mouth and constipation at both 5 mg and 10 mg doses; and urinary tract infection and blurred vision at the 10 mg dose. (6.1)

DRUG INTERACTIONS SECTION
7 DRUG INTERACTIONS
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 solifenacin succinate greater than 5 mg once daily is not recommended when concomitantly used with strong CYP3A4 inhibitors [see Dosage and Administration (2.4)].
CYP3A4 Inhibitors: Do not exceed the 5 mg dose of solifenacin succinate with concomitant use of strong CYP3A4 inhibitors. (7.1)
CLINICAL PHARMACOLOGY SECTION
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 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,
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 2.

1. 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.
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 solifenacin succinate in healthy volunteers, peak plasma concentrations (Cmax) of solifenacin were reached within 3 to 8 hours after administration and, at steady-state, ranged from 32.3 to 62.9 ng/mL for the 5 and 10 mg solifenacin succinate tablets, respectively. The absolute bioavailability of solifenacin is approximately 90%, with plasma concentrations of solifenacin proportional to the dose administered.
Effect of Food
Solifenacin succinate may be administered without regard to meals. A single 10 mg dose administration of solifenacin succinate with food increased Cmax and AUC of solifenacin by 4% and 3%, respectively.
Distribution
Solifenacin is approximately 98% (in vivo) bound to human plasma proteins, principally to α1-acid glycoprotein. Solifenacin is highly distributed to non- CNS tissues, having a mean steady-state volume of distribution of 600 L.
Elimination
The elimination half-life (t1/2) of solifenacin following chronic dosing is approximately 45-68 hours.
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 14C-solifenacin succinate to healthy 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
Geriatric Patients
Multiple dose studies of solifenacin succinate in geriatric volunteers (65 to
80 years) showed that Cmax, AUC and t1/2 values of solifenacin were 20-25%
higher compared to the younger adult volunteers (18 to 55 years). [See Use in Specific Populations (8.5)].
Patients with Renal Impairment
In studies with solifenacin succinate 10 mg, there was a 2.1-fold increase in
AUC and a 1.6-fold increase in t1/2 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, there was a 2-fold increase in
the t1/2 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
Strong CYP3A4 Inhibitors
In a crossover study, following blockade of CYP3A4 by coadministration of the strong CYP3A4 inhibitor, ketoconazole 400 mg once daily for 21 days, the mean Cmax 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, subjects received a single oral dose of warfarin 25 mg on the 10th 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 Cmax increased by 3% and AUC decreased by 2%. For S- warfarin, when it was coadministered with solifenacin succinate, the mean Cmax and AUC increased by 5% and 1%, respectively.
Oral Contraceptives
In a crossover study, 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 12th day of receipt of oral contraceptives. For ethinyl estradiol, when it was administered with solifenacin succinate, the mean Cmax and AUC increased by 2% and 3%, respectively. For levonorgestrel, when it was administered with solifenacin succinate, the mean Cmax and AUC decreased by 1%.
Digoxin
In a crossover study, 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 Cmax 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.
DOSAGE & ADMINISTRATION SECTION
2 DOSAGE AND ADMINISTRATION
2.1 Dosing Information
The recommended oral dose of solifenacin succinate tablets is 5 mg once daily. If the 5 mg dose is well tolerated, the dose may be increased to 10 mg once daily.
Solifenacin succinate tablets should be taken with water and swallowed whole. Solifenacin succinate tablets can be administered with or without food.
2.2 Dosing Recommendations in Patients with Renal Impairment
Do not exceed 5 mg once daily in patients with severe renal impairment (CLcr < 30 mL/min/1.73 m2) [ see Use in Specific Population (8.6)].
2.3 Dosing Recommendations in Patients with Hepatic Impairment

USE IN SPECIFIC POPULATIONS SECTION
8 USE IN SPECIFIC POPULATIONS
8.1 Pregnancy
Risk Summary
There are no studies with the use of solifenacin succinate in pregnant women
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 14C-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 solifenacin succinate and any potential adverse effects on
the breastfed child from solifenacin succinate or from the underlying maternal
condition.
Data
Animal Data
Oral administration of 14C-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 solifenacin succinate Tablets have not been established in pediatric patients.
8.5 Geriatric Use
In placebo-controlled clinical studies, similar safety and effectiveness were observed between geriatric patients (623 patients ≥ 65 years and 189 patients ≥ 75 years) and younger adult patients (1188 patients < 65 years) treated with solifenacin succinate [see Clinical Pharmacology (12.3)].
8.6 Renal Impairment
Solifenacin plasma concentrations are greater in patients with severe renal impairment compared to subjects 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 solifenacin succinate in patients with severe renal impairment (CLcr < 30 mL/min/1.73 m2) is 5 mg once daily [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 patients with moderate hepatic impairment compared to subjects 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 solifenacin succinate in patients with moderate hepatic impairment (Child-Pugh B) is 5 mg once daily [see Dosage and Administration (2.3)] and solifenacin succinate is not recommended for use in patients with severe hepatic impairment (Child-Pugh C).
8.8 Gender
The pharmacokinetics of solifenacin is not significantly influenced by gender.
OVERDOSAGE SECTION
10 OVERDOSAGE
Overdosage with solifenacin succinate 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. 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 volunteers taking 50 mg daily (5 times the maximum
recommended therapeutic dose) and resolved within 7 days following
discontinuation of drug.
In the event of overdose with solifenacin succinate, treat with gastric lavage
and appropriate supportive measures. ECG monitoring is also recommended.
DESCRIPTION SECTION
11 DESCRIPTION
Solifenacin succinate tablets (solifenacin succinate) is a muscarinic receptor antagonist. Chemically, solifenacin succinate is a butanedioic acid compound with (1S)-(3R)-1-azabicyclo[2.2.2]oct-3-yl 3,4-dihydro-1-phenyl-2(1H)-iso- quinolinecarboxylate(1:1) having an molecular formula of C23H26N2O2• C4H6O4 and a molecular weight of 480.55. The structural formula of solifenacin succinate is:

Solifenacin succinate is a white to pale-yellowish-white crystal or
crystalline powder. It is soluble in water and in methanol.
Each solifenacin succinate tablet contains 5 or 10 mg of solifenacin succinate
and is for oral administration. In addition to the active ingredient
solifenacin succinate, each solifenacin succinate tablet also contains the
following inactive ingredients: hypromellose, lactose monohydrate, magnesium
stearate, talc, titanium dioxide and triacetin with yellow ferric oxide (5 mg
solifenacin succinate tablet) or red ferric oxide (10 mg solifenacin succinate
tablet).
NONCLINICAL TOXICOLOGY SECTION
13 NONCLINICAL TOXICOLOGY
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.
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.
CLINICAL STUDIES SECTION
14 CLINICAL STUDIES
Solifenacin succinate was evaluated in four twelve-week, double-blind,
randomized, placebo-controlled, parallel group, multicenter clinical trials
for the treatment of overactive bladder in adult patients having symptoms of
urinary frequency, urgency, and/or urge or mixed incontinence (with a
predominance of urge). Entry criteria required that patients have symptoms of
overactive bladder for ≥ 3 months duration. These studies involved 3,027
patients (1811 on solifenacin succinate and 1216 on placebo), and
approximately 90% of these patients completed the 12-week studies. Two of the
four studies evaluated the 5 and 10 mg solifenacin succinate doses (Studies 1
and 2) and the other two evaluated only the 10 mg dose (Studies 3 and 4). All
patients completing the 12-week studies were eligible to enter an open-label,
long-term extension study (Study 5) and 81% of patients enrolling completed
the additional 40-week treatment period. The majority of patients were
Caucasian (93%) and female (80%) with a 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 succinate was similar across patient age groups
and gender. The mean reduction in the number of micturitions per 24 hours was
significantly greater with solifenacin succinate 5 mg (2.3; p < 0.001) and
solifenacin succinate 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 succinate 5 mg (1.5; p < 0.001) and
solifenacin succinate 10 mg (1.8; p < 0.001) treatment groups compared to the
placebo treatment group (1.1). The mean increase in the volume voided per
micturition was significantly greater with solifenacin succinate 5 mg (32.3
mL; p < 0.001) and solifenacin succinate 10 mg (42.5 mL; p < 0.001) compared
