In vitro study | Fesoterodine is rapidly and extensively converted to 5-HMT and therefore appears to be primarily responsible for the pharmacological activity of 5-HMT. In human M1-M5 cell lines, Fesoterodine is a competitive antagonist of cholinergic agonist-evoked responses and has similar potency and selectivity to radioligand studies. Fesoterodine caused a rightward shift of the concentration-effect curve of Carbachol in rat bladder muscle strips without decreasing its maximum and a concentration-dependent reduction of electric field stimulation (EFS)-induced contractions. Fesoterodin is hydrolyzed by non-specific esterases to 5-hydroxymethyl tolterodine (5-HMT), which is the active metabolite and is responsible for all antimuscarinic activity. |
