Oxybutynin acts as a competitive antagonist of acetylcholine at postganglionic muscarinic receptors, resulting in relaxation of bladder smooth muscle. OXYTROL, oxybutynin transdermal system, is designed to deliver oxybutynin continuously and consistently over a 3- to 4-day interval after application to intact skin. OXYTROL is available as a 39 cm2 system containing 36 mg of oxybutynin. OXYTROL has a nominal in vivo delivery rate of 3.9 mg oxybutynin per day through skin of average permeability (interindividual variation in skin permeability is approximately 20%).
OXYTROL is indicated for the treatment of overactive bladder with symptoms of urge urinary incontinence, urgency, and frequency.

Efficacy of oral extended-release oxybutynin in cognitively impaired older nursing home residents with urge urinary incontinence: a randomized placebo-controlled trial. [2011.11]
OBJECTIVES: To determine the efficacy of oral extended-release oxybutynin for urge urinary incontinence in older female nursing home residents with mild to severe cognitive impairment... CONCLUSION: Extended-release oxybutynin 5 mg per day for 4 weeks in older cognitively impaired female nursing home residents did not significantly reduce urinary incontinence and urinary frequency or achieve dryness. Participants with mild to moderate cognitive and/or physical impairment were no more likely to benefit from oxybutynin than more severely impaired individuals in an exploratory analysis but further research in a larger population and perhaps using a larger dose is needed.

Tolerability of solifenacin and oxybutynin immediate release in older (> 65 years) and younger (</= 65 years) patients with overactive bladder: sub-analysis from a Canadian, randomized, double-blind study. [2011.02]
CONCLUSIONS: Solifenacin 5 mg/day was better tolerated than oxybutynin IR 15 mg/day in younger (</= 65 years) and older (> 65 years) subgroups. Solifenacin was equally well tolerated in both age subgroups. Limitations of the analysis were that the study was not preplanned to perform post-hoc subgroup analysis, patients knew that dry mouth was a primary outcome, and the study used fixed doses of each drug.
[Comparisons of efficacy and safety of tolterodine and oxybutynin in children with idiopathic overactive bladder]. [2011.01]
OBJECTIVE: To compare the efficacy and safety of tolterodine and oxybutynin in the treatment of idiopathic overactive bladder in children... CONCLUSIONS: Tolterodine has a similar efficacy to oxybutynin in the treatment of idiopathic overactive bladder in children, with better safety in pharmacotherapy.
Clinical Trials Related to Oxytrol (Oxybutynin Transdermal)
OnabotulinumtoxinA (onaBoNT-A) Versus Oral Oxybutynin ER [Recruiting]
Overactive bladder is a condition associated with symptoms of feeling the urge to urinate,
urinating often, and may or may not be accompanied by leakage of urine. A patient who has a
spinal cord injury (SCI) often suffers from an overactive bladder which often leads to
urinary incontinence (UI - an unwanted leakage of urine).
OnaBoNT-A bladder injections have been studied in clinical research trials. The results
have shown an improvement in urinary symptoms by reducing how often urine leakage occurs and
by increasing the amount of urine the bladder can hold.
This purpose of this clinical trial is to see if onaBoNT-A is safe and effective when
injected into the bladder for the treatment of UI and if it works better than a drug that is
taken by mouth. A second purpose of the study is to perform research tests on the urine
samples provided by the volunteers. Urine presents a rich source of information for bladder
diseases and the biomarkers (the chemical make-up of the urine cells) will be examined to
learn if there are yet undiscovered reasons for urinary diseases. These tests would be very
beneficial because the results would lead to better treatment of the urinary diseases.
Volunteers will be randomized to either: ARM 1: onaBoNT-A 200 U bladder injection and
placebo oral capsule daily or ARM 2: Placebo bladder injection (saline) and oxybutynin ER
15mg capsule daily.
The treatments are onaBoNT-A bladder injection and a placebo oral capsule once a day or
placebo bladder injection and oxybutynin ER (like Ditropan) capsule once a day. Placebo
contains no active medicine. Participation in this study will be about 6-7 months and
involve 5 visits to the clinic. The risks of bladder onaBoNT-A
Use of Oxybutynin for Treating Hyperhidrosis: A Placebo-control Study [Completed]
Video-assisted thoracic sympathectomy (VATS) provides excellent resolution of palmar and
axillary hyperhidrosis but is associated with compensatory hyperhidrosis. Low doses of

Study of Topically Administered Oxybutynin Gel in Patients With Urge Incontinence [Completed]
The primary objective of the double-blind phase of the study is to compare the effects of
two doses of oxybutynin gel to placebo gel. The objective of the open-label extension is to
evaluate the extended safety and skin-irritation profile of topically administered
The hypothesis is that topically administered oxybutynin gel will decrease (compared to
placebo) the number of incontinence episodes per week, average daily urinary frequency, and
urinary urgency; increase average urinary void volume; and improve patient quality of life.
