Fesoterodine Fumarate is an orally active, nonsubtype selective, competitive muscarinic receptor (mAChR) antagonist with pKi values of 8.0, 7.7, 7.4, 7.3, 7.5 for M1, M2, M3, M4, M5 receptors, respectively. Fesoterodine Fumarate is used for the overactive bladder (OAB)[1][2].
FFesoterodine Fumarate decreases micturition frequency, urgency severity and urgency incontinence episodes and increases the volume voided with each micturition[1].
After oral administration, Fesoterodine Fumarate is rapidly and extensively hydrolysed in plasma by nonspecific esterases to Desfesoterodine (5-hydroxymethyl tolterodine; SPM 7605; HY-76569; an active metabolite of Fesoterodine)[3][4].
Fesoterodine Fumarate (0.01-1 mg/kg; IV) reduces the micturition pressure and increases bladder capacity and ICIs (intercontraction intervas) at the lowest dose tested of 0.01 mg/kg[3].
