Scopolamine powder, (hyoscine) also known as levo-duboisine or burundanga, 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 (Datura), angel's trumpets (Brugmansia), and corkwood (Duboisia). Scopolamine exerts its effects by acting as a competitive antagonist at muscarinic acetylcholine receptors; it is thus classified as an anticholinergic, antimuscarinic drug. Although it is usually referred to as a nonspecific antagonist, there is indirect evidence for m1-receptor subtype specificity.
