Scopolamine
Also Known As: Scopolamine, levo-duboisine, Hyoscine, Transderm-scop
Scopolamine, also known as levo-duboisine, and hyoscine, is a tropane alkaloid drug with muscarinic antagonist effects. It is among the secondary metabolites of plants from Solanaceae (nightshade) family of plants, such as henbane, jimson weed and Angel's Trumpets (Datura resp. Brugmansia spec.), and corkwood (Duboisia species). Scopolamine exerts its effects by acting as a competitive antagonist at muscarinic acetylcholine receptors, specifically M1 receptors; it is thus classified as an anticholinergic, anti-muscarinic drug. (See the article on the parasympathetic nervous system for details of this physiology.)
