5-Hydroxymethyl tolterodine formate

5-Hydroxymethyl tolterodine formate is a potent antagonist of muscarinic acetylcholine receptors (mAChR). This active metabolite, derived from tolterodine and fesoterodine through the action of CYP2D6 and plasma esterases respectively, has significant implications in the study of urinary disorders. Researchers can utilize 5-Hydroxymethyl tolterodine formate in pharmacological investigations of cholinergic signaling and its effects on smooth muscle activity, contributing to the understanding of treatment options for overactive bladder and related conditions.
