title: Transdermal oxybutynin: a review.
abstract: Overactive bladder is a common and disabling problem. The mainstay of pharmacological treatment is with oral anticholinergic drugs. Anticholinergic side effects are common and include dry mouth and constipation. Compliance is limited by these side effects. Transdermal administration of oxybutynin has been shown to be as effective as oral treatment while minimising the anticholinergic side effects. Skin reactions occur frequently, necessitating changes of application site. Despite this, the preparation is a useful element in the armamentarium to treat overactive bladder. It is likely to be particularly useful in those in whom side effects of oral medication are intolerable or in whom oral administration of drug is not possible. Here, the pharmacokinetics, pharmacodynamics, efficacy and safety of transdermal oxybutynin are reviewed.
