| Bioactivity | Fesoterodine L-mandelate 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 L-mandelate is used for the overactive bladder (OAB)[1][2]. |
| Target | pKi: 8.0 (M1), 7.7 (M2), 7.4 (M3), 7.3 (M4) and 7.5 (M5) |
| Invitro | Fesoterodine L-mandelate decreases micturition frequency, urgency severity and urgency incontinence episodes and increases the volume voided with each micturition[1].After oral administration, Fesoterodine L-mandelate 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]. |
| In Vivo | Fesoterodine L-mandelate (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]. Animal Model: |
