What is Ditropan?
Oxybutynin (Ditropan, Lyrinel XL, Lenditro (South Africa)) is an anticholinergic medication used to relieve urinary and bladder difficulties, including frequent urination and inability to control urination (urge incontinence), by decreasing muscle spasms of the bladder.
It competitively antagonizes the M1, M2, and M3 subtypes of the muscarinic acetylcholine receptor. It also has direct spasmolytic effects on bladder smooth muscle as a calcium antagonist and local anesthetic, but at concentrations far above those used clinically.
Oxybutynin is also a possible treatment of hyperhidrosis (hyper-active sweating).
