METHODS AND COMPOSITIONS FOR TREATING URINARY INCONTINENCE USING ENANTIOMERICALLY ENRICHED (S)-TRIHEXYPHENIDYL

摘要

A method for treating urinary incontinence, such as incontinence resulting from bladder detrusor muscle instability, using enantiomerically enriched (S)-trihexyphenidyl. The method comprises administering a therapeutically effective amount of enantiomerically enriched (S)-trihexyphenidyl, or a pharmaceutically acceptable salt thereof, substantially free of the (R)-trihexyphenidyl enantiomer. Pharmaceutical compositions for the treatment of urinary incontinence comprising enantiomerically enriched (S)-trihexyphenidyl, or a pharmaceutically acceptable salt thereof, and an acceptable carrier are also disclosed.
