What is Npc209773?

Plain description, key identifiers and synonyms

Atropine is a racemate composed of equimolar concentrations of (S)- and (R)-atropine. It is obtained from deadly nightshade (Atropa belladonna) and other plants of the family Solanaceae. It has a role as an antidote to sarin poisoning, a oneirogen, a bronchodilator agent, an anti-arrhythmia drug, a muscarinic antagonist, a parasympatholytic, a mydriatic agent, an anaesthesia adjuvant and a plant metabolite. It contains a (S)-atropine and a (R)-atropine.

Pharmacology

Atropine Sulfate is the sulfate salt of atropine, a naturally-occurring 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)
