Muscarinic Acetylcholine Receptor Agonist - an overview

WebWhen all three methyl groups are replaced by large alkyl groups of quaternary nitrogen, the drug loses its potency as an agonist. Carbachol There are exactly two steps may be needed to synthesize carbachol. By reacting 2-chloroethanol with urea, 2-chloroethyl-carbamate is formed, and by reacting trimethylamine with this compound, it is quaternised. Carbachol, also known as carbamylcholine and sold under the brand name Miostat among others, is a cholinomimetic drug that binds and activates acetylcholine receptors. Thus it is classified as a cholinergic agonist.
