摘要

A method for treating urinary incontinence while avoiding concomitant liability of adverse effects associated with racemic oxybutynin is disclosed. The method comprises administering a therapeutically effective amount of (S)-oxybutynin, (S)-desethyloxybutynin or a pharmaceutically acceptable salt thereof, substantially free of the corresponding R enantiomer. Pharmaceutical compositions in the form of tablets and transdermal devices comprising (S)-oxybutynin or (S)-desethyloxybutynin and an acceptable carrier are also disclosed, as is a synthesis of desethyloxybutynin.
