Definitions related to atropine:
-
A synthetically-derived form of the endogenous alkaloid isolated from the plant Atropa belladonna. Atropine functions as a sympathetic, competitive antagonist of muscarinic cholinergic receptors, thereby abolishing the effects of parasympathetic stimulation. This agent may induce tachycardia, inhibit secretions, and relax smooth muscles. (NCI04)NCI ThesaurusU.S. National Cancer Institute, 2021
-
An alkaloid, originally from Atropa belladonna, but found in other plants, mainly SOLANACEAE. Hyoscyamine is the 3(S)-endo isomer of atropine.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
-
Anticholinergic alkaloid originally from Atropa belladonna; used as an antispasmodic to relax smooth muscles, to increase heart rate by blocking the vagus nerve, as an antidote for various toxic and anticholinesterase agents, and as an antisecretory, mydriatic, and cycloplegic.CRISP ThesaurusNational Institutes of Health, 2006
