Atropine Sulfate: A Nonselective Muscarinic Acetylcholinergic Receptors Antagonist
Atropine sulfate is a tropane alkaloid which was first extracted from the root of belladonna (Atropa belladonna) in 1830s. Atropine sulfate is a enantiomeric mixture of (R,S)-hyoscyamine (dl-hyoscyamine), racemization occurring during the extraction procedure, whereas only (S)-hyoscyamine (l-hyoscyamine) is the active isomer. Atropine is a competitive antagonist of muscarine-like actions of acetylcholine and is therefore classified as an antimuscarinic agent. Atropine does not distinguish among the M1, M2, and M3 subgroups of muscarinic receptors. Atropine inhibits the action of acetylcholine at postganglionic nerve endings, thus affecting receptors of the exocrine glands, smooth muscle, cardiac muscle and the central nervous system.
