Oxybutynin (Oxybutynin Chloride) - Summary



Each scored oxybutynin chloride tablet contains 5 mg of oxybutynin chloride.

Oxybutynin chloride tablets are indicated for the relief of symptoms of bladder instability associated with voiding in patients with uninhibited neurogenic or reflex neurogenic bladder (i.e., urgency, frequency, urinary leakage, urge incontinence, dysuria).

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 Oxybutynin

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 Oxybutynin can be used to treat palmar hyperhidrosis with fewer side effects.

Treatment of Hyperhidrosis With Oxybutynin [Completed]

Evaluate the Efficacy of Oxybutynin Chloride in Patients With Primary Hyperhidrosis [Not yet recruiting]
Treatment of primary hyperhidrosis through a comparative study between oxybutynin hydrochloride and placebo. Hydrochloride may decrease the symptoms of hyperhidrosis improving the subject's quality of life.

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 oxybutynin gel. 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.
