Bethanacol 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.
Recommended dose rate in dogs is 1.25 - 5.0 mg given orally every 8 - 12 hrs.
