产品描述:
Solifenacin is a competitive antagonist of M1, M2, and M3 muscarinic acetylcholine receptors (Kis = 25, 125, and 10 nM, respectively, for the human receptors).{28353} It inhibits calcium mobilization induced by carbachol (carbamoylcholine; Item No. 14486) in isolated guinea pig detrusor muscle cells (Ki = 4 nM).{48902} Solifenacin inhibits carbachol-induced contraction of isolated guinea pig urinary bladder smooth muscle. In vivo, solifenacin (0.03-1 mg/kg) inhibits carbachol-induced increases in urinary bladder pressure in anesthetized rats. Formulations containing solifenacin have been used in the treatment of overactive bladder.
