Originally published by Bentham as Frontiers in Drug Design and Discovery, Volume 6and now distributed by Elsevier, this compilation of the sixteen articles, written by leading global researchers, focuses on key developments in the ... Cholinomimetics can be classified as: Direct-acting (receptor agonists), acting on muscarinic and nicotinic, and Indirect-acting (cholinesterase inhibitors), which, in turn, can be reversible or irreversible. These drugs are also called parasympathomimetic drugs because they produce effects that imitate parasympathetic nerve stimulation. Directly Acting Cholinergic Drugs: I.
