Background:

Bethanechol Chloride (Carbamyl-β-methylcholine chloride) is a selective muscarinic receptor agonist without any effect on nicotinic receptors.Target: mAChRBethanechol Chloride (Carbamyl-β-methylcholine chloride) is a parasympathomimetic choline carbamate that selectively stimulates muscarinic receptors without any effect on nicotinic receptors. Unlike acetylcholine, Bethanechol Chloride (Carbamyl-β-methylcholine chloride) 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 [1]. Bethanechol Chloride (Carbamyl-β-methylcholine chloride) has potential benefit in the treatment of cerebral palsy [2].
