Scopolamine Methyl Nitrate: A Belladonna Alkaloid with Anticholinergic Activity
Scopolamine salts ([
S0021][
S0230] and [
S0231]), belladonna alkaloids, are anticholinergic agents. Their free base, scopolamine competitively inhibits muscarinic receptors of the parasympathetic nervous system for acetylcholine and act as a nonselective muscarinic antagonist, producing peripheral anti-muscarinic, central sedative and antiemetic effects. The parasympatholytic scopolamine, structurally very similar to atropine [
A0754] as well, is used in conditions requiring decreased parasympathetic activity. Therefore, scopolamine can inhibit the secretion of saliva and sweat, decrease gastrointestinal secretions and motility, and increase heart rate
