5.5 Urinary Retention

Oxybutynin chloride extended-release tablets should be administered with caution to patients with clinically significant bladder outflow obstruction because of the risk of urinary retention [see Contraindications (4)].

5.6 Gastrointestinal Adverse Reactions

Oxybutynin chloride extended-release tablets should be administered with caution to patients with gastrointestinal obstructive disorders because of the risk of gastric retention [see Contraindications (4)].Oxybutynin chloride extended-release tablets, like other anticholinergic drugs, may decrease gastrointestinal motility and should be used with caution in patients with conditions such as ulcerative colitis and intestinal atony.Oxybutynin chloride extended-release tablets should be used with caution in patients who have gastroesophageal reflux and/or who are concurrently taking drugs (such as bisphosphonates) that can cause or exacerbate esophagitis.As with any other nondeformable material, caution should be used when administering Oxybutynin chloride extended-release tablets to patients with preexisting severe gastrointestinal narrowing (pathologic or iatrogenic). There have been rare reports of obstructive symptoms in patients with known strictures in association with the ingestion of other drugs in nondeformable controlled-release formulations.

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, the 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 clinical practice.The safety and efficacy of Oxybutynin chloride extended-release tablets (5 to 30 mg/day) was evaluated in 774 adult subjects who participated in five double-blind, controlled clinical trials. In four of the five studies, Oxybutynin chloride IR (5 to 20 mg/day in 199 subjects) was an active comparator. Adverse reactions reported by ≥ 1% of subjects are shown in Table 1.Table 1: Adverse Drug Reactions Reported by ≥ 1% of Oxybutynin chloride extended-release tablets-treated Adult Subjects in Five Double-blind, Controlled Clinical Trials of Oxybutynin chloride extended-release tabletsSystem/Organ ClassPreferred TermOxybutynin chloride extended-release tablets5 to 30 mg/dayn = 774%Oxybutynin chloride IRIR = immediate release5 to 20 mg/dayn = 199% Psychiatric Disorders   Insomnia 3.0 5.5 Nervous System Disorders   Headache 7.5 8.0   Somnolence 5.6 14.1   Dizziness 5.0 16.6   Dysgeusia 1.6 1.5 Eye Disorders   Vision blurred 4.3 9.6   Dry eye 3.1 2.5 Respiratory, Thoracic and Mediastinal Disorders   Cough 1.9 3.0   Oropharyngeal pain 1.9 1.5   Dry throat 1.7 2.5   Nasal dryness 1.7 4.5 Gastrointestinal Disorders   Dry mouth 34.9 72.4   Constipation 8.7 15.1   Diarrhea 7.9 6.5   Dyspepsia 4.5 6.0   Nausea 4.5 11.6   Abdominal pain 1.6 2.0   Vomiting 1.3 1.5   Flatulence 1.2 2.5   Gastro-esophageal reflux disease 1.0 0.5 Skin and Subcutaneous Tissue Disorders   Dry skin 1.8 2.5   Pruritus 1.3 1.5 Renal and Urinary Disorders   Dysuria 1.9 2.0   Urinary hesitation 1.9 8.5   Urinary retention 1.2 3.0 General Disorders and Administration Site Conditions   Fatigue 2.6 3.0 Investigations   Residual urine volumeThe bundled term residual urine volume consists of the preferred terms residual urine volume and residual urine volume increased. 2.3 3.5The discontinuation rate due to adverse reactions was 4.4% with Oxybutynin chloride extended-release tablets compared to 0% with Oxybutynin chloride IR. The most frequent adverse reaction causing discontinuation of study medication was dry mouth (0.7% ).The following adverse reactions were reported by <1% of Oxybutynin chloride extended-release tablets-treated patients and at a higher incidence than placebo in clinical trials: Metabolism and Nutrition Disorders: anorexia, fluid retention; Vascular disorders: hot flush; Respiratory, thoracic and mediastinal disorders: dysphonia; Gastrointestinal Disorders: dysphagia, frequent bowel movements; General disorders and administration site conditions: chest discomfort, thirst.

6.2 Postmarketing Experience

The following additional adverse reactions have been reported from worldwide postmarketing experience with Oxybutynin chloride extended-release tablets. Because postmarketing 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.Psychiatric Disorders: psychotic disorder, agitation, hallucinations, memory impairment; Nervous System Disorders: convulsions; Eye Disorders: glaucoma; Cardiac Disorders: arrhythmia, tachycardia, QT interval prolongation; Vascular Disorders: flushing; Skin and Subcutaneous Tissue Disorders: rash; Renal and Urinary Disorders: impotence; General Disorders and Administration Site Conditions: hypersensitivity reactions, including angioedema with airway obstruction, urticaria, and face edema; anaphylactic reactions requiring hospitalization for emergency treatment; Injury, poisoning and procedural complications: fall.Additional adverse events reported with some other oxybutynin chloride formulations include: cycloplegia, mydriasis, and suppression of lactation.To report SUSPECTED ADVERSE REACTIONS contact AvKARE, Inc. at 1-855-361-3993; email [email protected]; or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

7 Drug Interactions

The concomitant use of oxybutynin with other anticholinergic drugs or with other agents which produce dry mouth, constipation, somnolence (drowsiness), and/or other anticholinergic-like effects may increase the frequency and/or severity of such effects.Anticholinergic agents may potentially alter the absorption of some concomitantly administered drugs due to anticholinergic effects on gastrointestinal motility. This may be of concern for drugs with a narrow therapeutic index. Anticholinergic agents may also antagonize the effects of prokinetic agents, such as metoclopramide.Mean oxybutynin chloride plasma concentrations were approximately 2 fold higher when Oxybutynin chloride extended-release tablets was administered with ketoconazole, a potent CYP3A4 inhibitor. Other inhibitors of the cytochrome P450 3A4 enzyme system, such as antimycotic agents (e.g., itraconazole and miconazole) or macrolide antibiotics (e.g., erythromycin and clarithromycin), may alter oxybutynin mean pharmacokinetic parameters (i.e., Cmax and AUC). The clinical relevance of such potential interactions is not known. Caution should be used when such drugs are co-administered.

8.3 Nursing Mothers

It is not known whether oxybutynin is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Oxybutynin chloride extended-release tablets is administered to a nursing woman.

8.4 Pediatric Use

The safety and efficacy of Oxybutynin chloride extended-release tablets were studied in 60 children in a 24-week, open-label, non-randomized trial. Patients were aged 6–15 years, all had symptoms of detrusor overactivity in association with a neurological condition (e.g., spina bifida), all used clean intermittent catheterization, and all were current users of oxybutynin chloride. Study results demonstrated that administration of Oxybutynin chloride extended-release tablets 5 to 20 mg/day was associated with an increase from baseline in mean urine volume per catheterization from 108 mL to 136 mL, an increase from baseline in mean urine volume after morning awakening from 148 mL to 189 mL, and an increase from baseline in the mean percentage of catheterizations without a leaking episode from 34% to 51%.Urodynamic results were consistent with clinical results. Administration of Oxybutynin chloride extended-release tablets resulted in an increase from baseline in mean maximum cystometric capacity from 185 mL to 254 mL, a decrease from baseline in mean detrusor pressure at maximum cystometric capacity from 44 cm H2O to 33 cm H2O, and a reduction in the percentage of patients demonstrating uninhibited detrusor contractions (of at least 15 cm H2O) from 60% to 28%.The pharmacokinetics of Oxybutynin chloride extended-release tablets in these patients were consistent with those reported for adults [see Clinical Pharmacology (12.3)]. Oxybutynin chloride extended-release tablets is not recommended in pediatric patients who cannot swallow the tablet whole without chewing, dividing, or crushing, or in children under the age of 6.

8.5 Geriatric Use

The rate and severity of anticholinergic effects reported by patients less than 65 years old and those 65 years and older were similar. The pharmacokinetics of Oxybutynin chloride extended-release tablets were similar in all patients studied (up to 78 years of age).

8.6 Renal Impairment

There were no studies conducted with Oxybutynin chloride extended-release tablets in patients with renal impairment.

8.7 Hepatic Impairment

There were no studies conducted with Oxybutynin chloride extended-release tablets in patients with hepatic impairment.

10 Overdosage

The continuous release of oxybutynin from Oxybutynin chloride extended-release tablets should be considered in the treatment of overdosage. Patients should be monitored for at least 24 hours. Treatment should be symptomatic and supportive. Activated charcoal as well as a cathartic may be administered.Overdosage with oxybutynin chloride has been associated with anticholinergic effects including central nervous system excitation, flushing, fever, dehydration, cardiac arrhythmia, vomiting, and urinary retention.Ingestion of 100 mg oxybutynin chloride in association with alcohol has been reported in a 13-year-old boy who experienced memory loss, and a 34-year-old woman who developed stupor, followed by disorientation and agitation on awakening, dilated pupils, dry skin, cardiac arrhythmia, and retention of urine. Both patients fully recovered with symptomatic treatment.

11 Description

Oxybutynin chloride extended-release tablets is an antispasmodic, muscarinic antagonist. Each Oxybutynin chloride extended-release tablets contains 5 mg, 10 mg, or 15 mg of oxybutynin chloride USP, formulated as a once-a-day controlled-release tablet for oral administration. Oxybutynin chloride is administered as a racemate of R- and S-enantiomers.Chemically, oxybutynin chloride is d,l (racemic) 4-diethylamino-2-butynyl phenylcyclohexylglycolate hydrochloride. The empirical formula of oxybutynin chloride is C22H31NO3•HCl.Its structural formula is:Oxybutynin chloride is a white crystalline solid with a molecular weight of 393.9. It is readily soluble in water and acids, but relatively insoluble in alkalis.Oxybutynin chloride extended-release tablets also contain the following inert ingredients: lactose, mannitol, dextrose, tartaric acid, colloidal silicon dioxide, magnesium stearate, cellulose acetate, polyethylene glycol, titanium dioxide, triacetin, black iron oxide, propylene glycol, hypromellose.

12.1 Mechanism Of Action

Oxybutynin relaxes bladder smooth muscle. Oxybutynin chloride exerts a direct antispasmodic effect on smooth muscle and inhibits the muscarinic action of acetylcholine on smooth muscle. No blocking effects occur at skeletal neuromuscular junctions or autonomic ganglia (antinicotinic effects).Antimuscarinic activity resides predominantly in the R-isomer. A metabolite, desethyloxybutynin, has pharmacological activity similar to that of oxybutynin in in vitro studies.

12.2 Pharmacodynamics

In patients with conditions characterized by involuntary bladder contractions, cystometric studies have demonstrated that oxybutynin increases bladder (vesical) capacity, diminishes the frequency of uninhibited contractions of the detrusor muscle, and delays the initial desire to void.

13.1 Carcinogenesis, Mutagenesis, Impairment Of Fertility

A 24-month study in rats at dosages of oxybutynin chloride of 20, 80, and 160 mg/kg/day showed no evidence of carcinogenicity. These doses are approximately 6, 25, and 50 times the maximum human exposure, based on a human equivalent dose taking into account normalization of body surface area.Oxybutynin chloride showed no increase of mutagenic activity when tested in Schizosaccharomyces pompholiciformis, Saccharomyces cerevisiae, and Salmonella typhimurium test systems.Reproduction studies with oxybutynin chloride in the mouse, rat, hamster, and rabbit showed no evidence of impaired fertility.

14 Clinical Studies

Oxybutynin chloride extended-release tablets was evaluated for the treatment of patients with overactive bladder with symptoms of urge urinary incontinence, urgency, and frequency in three controlled efficacy studies. The majority of patients were Caucasian (89.0%) and female (91.9%) with a mean age of 59 years (range, 18 to 98 years). Entry criteria required that patients have urge or mixed incontinence (with a predominance of urge) as evidenced by ≥ 6 urge incontinence episodes per week and ≥ 10 micturitions per day. Study 1 was a fixed-dose escalation design, whereas the other two studies used a dose-adjustment design in which each patient's final dose was adjusted to a balance between improvement of incontinence symptoms and tolerability of side effects. All three studies included patients known to be responsive to oxybutynin or other anticholinergic medications, and these patients were maintained on a final dose for up to 2 weeks.The efficacy results for the three controlled trials are presented in the following tables and figures.Number of Urge Urinary Incontinence Episodes Per WeekStudy 1nOxybutynin chloride extended-release tabletsnPlacebo Mean Baseline 34 15.9 16 20.9 Mean (SD) Change from BaselineCovariate adjusted mean with missing observations set to baseline values 34 -15.8 (8.9) 16 -7.6 (8.6) 95% Confidence Interval for Difference (-13.6, -2.8)The difference between Oxybutynin chloride extended-release tabletsand placebo was statistically significant. (Oxybutynin chloride extended-release tablets- Placebo)Figure 2Study 2nOxybutynin chloride extended-release tabletsnoxybutynin Mean Baseline 53 27.6 52 23.0 Mean (SD) Change from BaselineCovariate adjusted mean with missing observations set to baseline values 53 -17.6 (11.9) 52 -19.4 (11.9) 95% Confidence Interval for Difference (-2.8, 6.5) (Oxybutynin chloride extended-release tablets- oxybutynin)Figure 3Study 3nOxybutynin chloride extended-release tabletsnoxybutynin Mean Baseline 111 18.9 115 19.5 Mean (SD) Change from BaselineCovariate adjusted mean with missing observations set to baseline values 111 -14.5 (8.7) 115 -13.8 (8.6) 95% Confidence Interval for Difference (-3.0, 1.6)The difference between Oxybutynin chloride extended-release tabletsand oxybutynin fulfilled the criteria for comparable efficacy. (Oxybutynin chloride extended-release tablets- oxybutynin)Figure 4
