HIDE SMILES / InChI
The alkaloid L-(-)-scopolamine [L-(-)-hyoscine], a belladonna alkaloid, competitively inhibits muscarinic receptors for acetylcholine and acts as a nonselective muscarinic antagonist, producing both peripheral antimuscarinic properties and central sedative, antiemetic, and amnestic effects. Scopolamine acts: i) as a competitive inhibitor at postganglionic muscarinic receptor sites of the parasympathetic nervous system, and ii) on smooth muscles that respond to acetylcholine but lack cholinergic innervation. It has been suggested that scopolamine acts in the central nervous system (CNS) by blocking cholinergic transmission from the vestibular nuclei to higher centers in the CNS and from the reticular formation to the vomiting center. Scopolamine can inhibit the secretion of saliva and sweat, decrease gastrointestinal secretions and motility, cause drowsiness, dilate the pupils, increase heart rate, and depress motor function. Scopolamine is used for premedication in anesthesia and for the prevention of nausea and vomiting (post operative and associated with motion sickness).

Curator's Comment: Scopolamine is an anticholinergic, tropane alkaloid isolated from Datura metel L., Scopola carniolica Jacq. and other Solanaceae. Constituent of impure duboisine from Duboisia myoporoides R. Br., pure duboisine is l-hyoscyamine, q.v. reference retrieved from http://www.drugfuture.com/chemdata/scopolamine.html

Sample Use Guides

Transderm Scōp (scopolamine) transdermal system patch. Each Transderm Scōp patch is formulated to deliver in-vivo approximately 1 mg of scopolamine over 3 days. Initiation of Therapy Motion Sickness To prevent the nausea and vomiting associated with motion sickness, one Transderm Scōp patch (formulated to deliver approximately 1 mg of scopolamine over 3 days) should be applied to the hairless area behind one ear at least 4 hours before the antiemetic effect is required. Post Operative Nausea and Vomiting To prevent post operative nausea and vomiting, one Transderm Scōp patch should be applied the evening before scheduled surgery, except for caesarian section. For caesarian section surgery, to minimize exposure of the newborn baby to the drug, apply the patch one hour prior to caesarian section. Continuation of Therapy Should the patch become displaced, it should be discarded, and a fresh one placed on the hairless area behind the other ear. Motion Sickness If therapy is required for longer than 3 days, the first patch should be removed and a fresh one placed on the hairless area behind the other ear. Post Operative Nausea and Vomiting For perioperative use, the patch should be kept in place for 24 hours following surgery at which time it should be removed and discarded.
Route of Administration: Transdermal
