An action or drug that inhibits the activity of ACETYLCHOLINE.
An agent that impedes the impulses or actions of the nerves or fibers of the parasympathetic ganglia, competing with, and blocking the release of acetycholine at what are called the muscarinic sites. Cholinergic functions affected are those that induce spasms and cramps of the intestinal tracts and allied ducts. Examples: Atropine, Datura, Garrya.
