Bethanechol Chloride is a selective muscarinic receptor agonist without any effect on nicotinic receptors. Target: mAChR Bethanechol is a parasympathomimetic choline carbamate that selectively stimulates muscarinic receptors without any effect on nicotinic receptors. Unlike acetylcholine, bethanechol is not hydrolyzed by cholinesterase and will therefore have a long duration of action. Oral bethanechol significantly improves contraction pressures and bolus transit in the smooth muscle portion of the esophagus in patients with severe IEM . Bethanechol has potential benefit in the treatment of cerebral palsy .Bethanechol氯化物是毒蕈碱型受体（mAChR）选择性激动剂，而对烟碱受体无活性 Bethanechol Chloride is a selective muscarinic receptor agonist without any effect on nicotinic receptors.
