产品描述:
Bethanechol is an agonist of muscarinic acetylcholine receptors with IC50 values of 1,837, 25, 631, 317, and 393 µM for M1-5, respectively, in a radioligand binding assay using CHO cells expressing the human receptors.{40682} It inhibits M2-mediated increases in cyclic AMP induced by isoproterenol (Item No. 15592) in isolated guinea pig small intestine (IC50 = 127 µM).{18340} Bethanechol increases basal tone of isolated porcine intravesical ureter (EC50 = 4.27 µM).{27105} It also induces fluid secretion in the ileum, duodenum, and jejunum of anesthetized rats when administered at a dose of 60 µg/kg.{40787} Formulations containing bethanechol have been used to increase urination and improve smooth muscle tone in the gastrointestinal tract.
