Description

Application

(−)-Scopolamine methyl bromide was administered to rats to inhibit the peripheral cholinergic effects induced by pilocarpine.^10,11

Biochem/physiol Actions

Competitive muscarinic acetylcholine receptor antagonist.

Scopolamine is an anti-muscarinic and cholinolytic alkaloid that inhibits parasympathetic-cholinergic system.⁷ The central effects include hallucinations, disorientation, restlessness and euphoria.⁸ Scopolamine disturb the stimulus detection performance in rats by interfering with the reticular cholinergic pathways.⁹

Caution

Shelf-life of the powder is at least five years when stored at room temperature.
