Isoscopil: Full Drug Profile

Medically reviewed by Min Clinic Staff | Updated: January 2026

Isoscopil - General Information

An alkaloid from Solanaceae, especially Datura metel L. and Scopola carniolica. Isoscopil and its quaternary derivatives act as antimuscarinics like atropine, but may have more central nervous system effects. Among the many uses are as an anesthetic premedication, in urinary incontinence, in motion sickness, as an antispasmodic, and as a mydriatic and cycloplegic. [PubChem]

 

Pharmacology of Isoscopil

Isoscopil is a muscarinic antagonist structurally similar to the neurotransmitter acetylcholine and acts by blocking the muscarinic acetylcholine receptors and is thus classified as an anticholinergic. Isoscopil has many uses including the prevention of motion sickness. It is not clear how Isoscopil prevents nausea and vomiting due to motion sickness. The vestibular part of the ear is very important for balance. When a person becomes disoriented due to motion, the vestibule sends a signal through nerves to the vomiting center in the brain, and vomiting occurs. Acetylcholine is a chemical that nerves use to transmit messages to each other. It is believe that Isoscopil prevents communication between the nerves of the vestibule and the vomiting center in the brain by blocking the action of acetylcholine. Isoscopil also may work directly on the vomiting center. Isoscopil must be taken before the onset of motion sickness to be effective.

 

Isoscopil for patients

 

Isoscopil Interactions

The absorption of oral medications may be decreased during the concurrent use of scopolamine because of decreased gastric motility and delayed gastric emptying.

Scopolamine should be used with care in patients taking other drugs that are capable of causing CNS effects such as sedatives, tranquilizers, or alcohol. Special attention should be paid to potential interactions with drugs having anticholinergic properties; e.g., other belladonna alkaloids, antihistamines (including meclizine), tricyclic antidepressants, and muscle relaxants.

Laboratory Test Interactions

Scopolamine will interfere with the gastric secretion test.

 

Isoscopil Contraindications

Transderm Scop is contraindicated in persons who are hypersensitive to the drug scopolamine or to other belladonna alkaloids, or to any ingredient or component in the formulation or delivery system, or in patients with angle-closure (narrow angle) glaucoma.
