Product Description

Biological Activity

Description Fesoterodine Fumarate is a prodrug of 5-hydroxymethyl tolterodine that is a muscarinic AChR receptor antagonist, used to treat overactive bladder syndrome.
Targets AChR [1]
In vitro Fesoterodine is rapidly and extensively converted to 5-HMT, such that the pharmacologic activity appears to be primarily attributable to 5-HMT. [1] Fesoterodine is a competitive antagonist of cholinergic agonist-stimulated responses in human M1-M5 cell lines and has a similar potency and selectivity profile to the radioligand-binding studies. Fesoterodine causes a rightward shift of the concentration-response curve for carbachol with no depression of the maximum in rat bladder strips, and concentration-dependently reduces contractions induced by electrical field stimulation (EFS). [2] Fesoterodine is hydrolyzed by nonspecific esterases to 5-hydroxmethyl tolterodine (5-HMT), which is the active metabolite and is responsible for all its antimuscarinic activity. [3]

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.

Rat dose (mg/kg) = mouse dose (22.4 mg/kg) ×  mouse Km(3)  = 11.2 mg/kg
