4 CONTRAINDICATIONS

The use of Oxybutynin 3% is contraindicated in patients with the following conditions:

  • Urinary retention [see  Warnings and Precautions (5.1) ].

  • Gastric retention [see  Warnings and Precautions (5.2) ].

  • Uncontrolled narrow-angle glaucoma [see  Warnings and Precautions (5.8) ].
  • Urinary retention (4)

  • Gastric retention (4)

  • Uncontrolled narrow-angle glaucoma (4)

5 WARNINGS AND PRECAUTIONS

  • Urinary Retention: Caution should be exercised in patients with clinically significant bladder outflow obstruction because of urinary retention risk.

  • Gastrointestinal Disorders: Use with caution in patients with gastroesophageal reflux and/or those taking drugs that can cause or exacerbate esophagitis and in patients with decreased intestinal motility or gastrointestinal obstructive disorders because of the risk of gastric retention. (5.2)

  • Skin Transference: Advise patients to cover the application site with clothing if skin-to-skin contact at the application site is anticipated. Wash hands immediately after product application. (5.3)

  • Flammable Gel: Contains alcohol-based gel. Avoid open fire or smoking until the gel has dried. (5.4)

  • Central Nervous System Effects: Somnolence has been reported with drugs containing Oxybutynin. Advise patients not to drive or operate heavy machinery until they know how Oxybutynin 3% affects them. (5.5)

  • Myasthenia Gravis: Administer Oxybutynin 3% with caution in patients with myasthenia gravis, a disease characterized by decreased cholinergic activity at the neuromuscular junction. (5.6)

  • Angioedema: Angioedema has been reported with oral Oxybutynin use. If symptoms of angioedema occur, discontinue Oxybutynin 3% and initiate appropriate therapy. (5.7)

  • Controlled Narrow-Angle Glaucoma: Administer Oxybutynin 3% with caution in patients being treated for narrow-angle glaucoma. (5.8)

5.1 Urinary Retention

Use Oxybutynin 3% with caution in patients with clinically significant bladder outflow obstruction because of the risk of urinary retention.

5.2 Use in Patients with Gastrointestinal Disorders

Use Oxybutynin 3% with caution in patients with gastrointestinal obstructive disorders because of the risk of gastric retention.

Oxybutynin 3%, like other anticholinergic drugs, may decrease gastrointestinal motility and should be used with caution in patients with conditions such as ulcerative colitis or intestinal atony.

Oxybutynin 3% should be used with caution in patients who have gastroesophageal reflux and/or who are concurrently taking drugs that can cause or exacerbate esophagitis.

5.3 Skin Transference

Transfer of Oxybutynin to another person can occur when vigorous bare skin-to-skin contact is made with the application site. To minimize the potential transfer of Oxybutynin from treated skin to another person, patients should cover the application site with clothing after the gel has dried if direct skin-to-skin contact at the application site is anticipated [see  Clinical Pharmacology (12.3) ]. Patients should wash their hands immediately after application of Oxybutynin 3%.

5.4 Flammable Gel

Oxybutynin 3% is an alcohol-based gel and is therefore flammable. Avoid open fire or smoking until gel has dried. 

5.5 Central Nervous System Effects

Drugs containing Oxybutynin are associated with anticholinergic central nervous system effects. A variety of CNS anticholinergic effects have been reported, including headache, dizziness, somnolence, confusion and hallucinations . Patients should be monitored for signs of anticholinergic CNS effects, particularly after beginning treatment. Advise patients not to drive or operate heavy machinery until they know how Oxybutynin 3% affects them. If a patient experiences anticholinergic CNS effects, drug discontinuation should be considered.

5.6 Myasthenia Gravis

Administer Oxybutynin 3% with caution in patients with myasthenia gravis, a disease characterized by decreased cholinergic activity at the neuromuscular junction. 

5.7 Angioedema

Angioedema requiring hospitalization and emergency medical treatment has occurred with the first or subsequent doses of oral Oxybutynin.  In the event of angioedema, Oxybutynin containing product should be discontinued and appropriate therapy promptly provided.

5.8 Controlled Narrow-Angle Glaucoma

Administer Oxybutynin 3% with caution in patients being treated for narrow-angle glaucoma.

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 trial of another drug and may not reflect the rates observed in practice.

The safety of Oxybutynin 3% was evaluated in 626 patients (210 randomized to Oxybutynin 3% 56 mg/day, 214 randomized to Oxybutynin 3% 84 mg/day and 202 randomized to placebo) during a randomized, placebo-controlled, double-blind, 12-week clinical efficacy and safety study. A subset of these 626 patients (N = 77) participated in the 24-week open-label safety extension that followed the placebo-controlled study. Of the 77 patients in the safety extension, 24 were randomized to placebo gel during the double-blind, placebo-controlled 12-week study. In the combined double-blind, placebo-controlled study and the open-label safety extension, a total of 441 patients were exposed to at least one dose of Oxybutynin 3%. 364 patients received at least 12 weeks of Oxybutynin 3% treatment and 66 patients received an additional 24 weeks of Oxybutynin 3% treatment during the open-label safety extension. The study population primarily consisted of women (87%) of Caucasian descent (87%) with an average age of 59 years who had overactive bladder with urge urinary incontinence.

Table 1 lists adverse reactions (ARs), regardless of causality, that were reported in the randomized, double-blind, placebo-controlled 12-week study at an incidence greater than placebo and in greater than 3% of patients treated with Oxybutynin 3%.

Overall, 672 ARs were experienced by 51.9% of patients. Majority of the ARs were mild to moderate in intensity. The AR most commonly reported was dry mouth which was experienced by a greater proportion of patients in the Oxybutynin group than the placebo group (26 patients [12.1%] in the Oxybutynin 84 mg group, 10 patients [5.0%] in the placebo group). Application site erythema was the next most commonly reported AR (8 patients [3.7%] in the Oxybutynin 84 mg group and 2 patients [1.0%] in the placebo group). Other commonly reported ARs experienced by more patients in the Oxybutynin groups compared with placebo were application site rash (7 patients [3.3%] in the Oxybutynin 84 mg group and 1 patient [0.5%] in the placebo group); application site pruritus (6 patients [2.8%] in the Oxybutynin 84 mg group and 1 patient [0.5%] in the placebo group).  The overall rate of application site adverse reactions of any kind was 14.2% in patients receiving Oxybutynin 3% as compared to 3.7% in patients receiving placebo.  Other cholinergic AEs < 2% in occurrence include dry eyes and blurred vision.

There were no deaths during the study. There were no clinically meaningful changes in vital signs, laboratory values, or ECG examinations over the course of the study.

7 DRUG INTERACTIONS

No specific drug-drug interaction studies have been performed with Oxybutynin 3%.

  • Concomitant use with other anticholinergic agents may increase the frequency and/or severity of dry mouth, constipation, and blurred vision and other anticholinergic pharmacological effects. (7.1)

7.1 Other Anticholinergics

The concomitant use of Oxybutynin 3% with other anticholinergic (antimuscarinic) agents may increase the frequency and/or severity of dry mouth, blurred vision, and other anticholinergic pharmacological effects. 

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Pregnancy Category B.

There are no adequate and well-controlled studies of topical or oral Oxybutynin use in pregnant women. Reproduction studies using Oxybutynin chloride in the hamster, rabbit, rat, and mouse have shown no evidence of impaired fertility or harm to the fetus. The safety of Oxybutynin 3% administration to women who are or who may become pregnant has not been established. Therefore, Oxybutynin 3% should not be given to pregnant women unless, in the judgment of the physician, the probable clinical benefits outweigh the possible hazards. 

8.2 Labor and Delivery

Oxybutynin 3% has not been studied for use during labor and delivery. Treatment should only be given if clearly needed.

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 3% is administered to a nursing woman.

8.4 Pediatric Use

The safety and effectiveness of Oxybutynin 3% have not been established in pediatric patients. 

8.5 Geriatric Use

Of the 424 patients exposed to Oxybutynin 3% in the randomized, double-blind, placebo-controlled 12-week study, 182 patients were 65 years of age and older. No overall differences in safety or effectiveness were observed between these patients and younger patients.

8.6 Renal Impairment

Patients with renal impairment received Oxybutynin 3% during clinical trials. These trials were not designed to determine whether there were differences in safety or effectiveness in patients with or without impaired renal function. 

8.7 Hepatic Impairment

Patients with hepatic impairment received Oxybutynin 3% during clinical trials. These trials were not designed to determine whether there were differences in safety or effectiveness in patients with or without impaired hepatic function.

10 OVERDOSAGE

Overdosage with Oxybutynin has been associated with anticholinergic effects including central nervous system excitation, flushing, fever, dehydration, cardiac arrhythmia, vomiting, exhaustion, heat sensitivity, and urinary retention. Oral ingestion of 100 mg Oxybutynin chloride in association with alcohol has been reported in a 13-year-old who experienced memory loss, and in a 34-year-old who developed stupor, followed by disorientation and agitation on awakening, dilated pupils, dry skin, cardiac arrhythmia, and retention of urine. Both patients recovered fully with symptomatic treatment. If overexposure occurs, monitor patients until symptoms resolve.

11 DESCRIPTION

Oxybutynin is an antispasmodic, antimuscarinic agent. Oxybutynin 3% is a topical, homogeneous, very lightly to moderately opalescent, translucent colorless to slightly colored gel, without particles. The product is a hydroalcoholic gel containing 30 mg Oxybutynin per gram of gel. Oxybutynin 3% is available in a 0.92 gram (1 mL) unit dose that contains 28 mg Oxybutynin. Oxybutynin is delivered as a racemate of R- and S-isomers. Chemically, Oxybutynin base is d, l (racemic) 4-(Diethylamino)-2-butynyl (±)-α-phenylcyclohexaneglycolate.

The empirical formula of Oxybutynin base is C22H31NO3. Its structural formula is:

Distribution

Oxybutynin is widely distributed in body tissues following systemic absorption. The volume of distribution was estimated to be 193 L after intravenous administration of 5 mg Oxybutynin chloride.

Metabolism

Oxybutynin is metabolized primarily by the cytochrome P450 enzyme systems, particularly CYP3A4, found mostly in the liver and gut wall. Metabolites include N-desethyloxybutynin (DEO), which is pharmacologically active and phenylcyclohexylglycolic acid, which is pharmacologically inactive.

Transdermal administration of Oxybutynin bypasses the first-pass gastrointestinal and hepatic metabolism, reducing the formation of the N-desethyloxybutynin metabolite. Only small amounts of CYP3A4 are found in skin, limiting pre-systemic metabolism during transdermal absorption. The AUC ratio of N-desethyloxybutynin metabolite to parent compound following multiple transdermal applications is approximately 1:1 for Oxybutynin 3%. The apparent half-life was approximately 30 hours.

Excretion

Oxybutynin undergoes extensive hepatic metabolism, with less than 0.1% of the administered dose excreted unchanged in the urine. Less than 0.1% of the administered dose is excreted as the metabolite N-desethyloxybutynin.

Person-to-Person Transference

The potential for dermal transfer of Oxybutynin from a treated person to an untreated person was evaluated in a single-dose study where subjects dosed with Oxybutynin 3% engaged in vigorous contact with an untreated partner for 15 minutes, either with (N = 14 couples) or without (N = 14 couples) clothing covering the application area. The untreated partners not protected by clothing demonstrated low detectable plasma concentrations of Oxybutynin (mean Cmax = 0.65 ng/mL). Only one of the 14 untreated subjects participating in the clothing-to-skin contact regimen had very low measurable Oxybutynin plasma concentrations (Cmax = 0.06 ng/mL) during the 24 hours following contact with treated subjects; Oxybutynin was not detectable with the remaining 13 untreated subjects. Regardless of the low exposure observed in this study, patients should avoid skin-to-skin contact with partners after applying the gel.

Use of Sunscreen

The effect of sunscreen on the absorption of Oxybutynin when applied 30 minutes before or 30 minutes after Oxybutynin 3% application was evaluated in a single-dose randomized crossover study (N = 20). Concomitant application of sunscreen, either before or after Oxybutynin 3% application, had no effect on the systemic exposure of Oxybutynin.

Showering

The effect of showering on the absorption of Oxybutynin was evaluated in a randomized, steady-state crossover study under conditions of no shower, or showering 1, 2 or 6 hours after Oxybutynin 3% application (N = 22). The results of the study indicate that showering one hour after administration does not affect the overall systemic exposure to Oxybutynin.

Race

The effect of race on the pharmacokinetics of Oxybutynin 3% has not been studied.

Geriatric Patients

Available data suggest that there are no significant differences in the pharmacokinetics of Oxybutynin based on geriatric status in patients following administration of Oxybutynin 3% [see  Use in Specific Populations (8.5) ].

Pediatric Patients

The pharmacokinetics of Oxybutynin and N-desethyloxybutynin following application of Oxybutynin 3% has not been evaluated in individuals younger than 18 years of age [see Use in Specific Populations (8.4) ].

Gender

Available data suggest that there are no significant differences in the pharmacokinetics of Oxybutynin based on gender in healthy volunteers following administration of Oxybutynin 3%.

Renal Impairment

There is limited experience with the use of Oxybutynin 3% in patients with renal insufficiency [see  Use in Specific Populations (8.6) ].

Hepatic Impairment

There is limited experience with the use of Oxybutynin 3% in patients with hepatic insufficiency [see  Use in Specific Populations (8.7) ].

13 NONCLINICAL TOXICOLOGY

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 showed no evidence of carcinogenicity. These doses are approximately 6, 25, and 50 times the maximum exposure in humans taking an oral dose, based on 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

The efficacy and safety of Oxybutynin 3% were evaluated in a single randomized, double-blind, placebo-controlled, multicenter 12-week study in patients with urinary frequency and urge and mixed urinary incontinence with a predominance of urge incontinence episodes.  This was followed by an open-label safety extension. Key entry criteria included adults with overactive bladder (OAB) symptoms for at least 3 months who were either treatment-naïve or had demonstrated a beneficial response to anticholinergic treatment for OAB. Subjects were randomly assigned to receive 84 mg/day Oxybutynin, 56 mg/day Oxybutynin, or placebo. A total of 214 patients received 84 mg/day Oxybutynin, 210 patients received 56 mg/day Oxybutynin, and 202 patients received placebo gel. The majority of patients were Caucasian (87%) and female (87%), with a mean age of 59 years (range: 19 to 89 years). The primary efficacy endpoint was the change from baseline to week 12 in the number of urinary incontinence episodes (UIE) per week, as determined from a 3‑day patient daily diary.

Patients treated with Oxybutynin 3% (84 mg) experienced a statistically significant decrease in the number of urinary incontinence episodes per week from baseline to endpoint (the primary efficacy endpoint) compared with placebo (p = 0.0445) and patients treated with the 56 mg dose did not show statistically significant efficacy.  Statistically significant improvements in daily urinary frequency (p = 0.0010) and urinary void volume (p < 0.0001) were also seen with Oxybutynin 3% (84 mg) relative to placebo.  The mean difference from placebo for Oxybutynin 3% (84 mg) was -2.3 for urinary incontinence episodes per week in a group of patients with a mean of greater than 40 incontinence episodes per week at baseline.  Mean and median change from baseline in weekly incontinence episodes (primary endpoint), daily urinary frequency, and urinary void volume (secondary endpoints) between placebo and Oxybutynin 3% are summarized in Table 3.
