The evolution of different delivery systems led first to intravesical administration, anal suppositories, and then to the commercial development of an extended-release oral formulation of oxybutynin chloride to improve its tolerability while maintaining efficacy. These modes of delivery were associated with decreased antimuscarinic side effects and N-desethyloxybutynin serum levels by avoiding first-pass metabolism in the upper gut and liver. The development of transdermal delivery has carried this evolution even further, with serum levels of desethyloxybutynin < or = oxybutynin and dry mouth rates of 7%, with little constipation. The new development of a transdermal oxybutynin gel has decreased these application site reactions to low levels while maintaining good efficacy. | | Language | eng | | Pub Type(s) | Journal Article
