Metabolite Identification
Common NameN-desethyloxybutynin
DescriptionN-desethyloxybutynin is a metabolite of oxybutynin. Oxybutynin (Ditropan, Lyrinel XL) is an anticholinergic medication used to relieve urinary and bladder difficulties, including frequent urination and inability to control urination, 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. (Wikipedia)
