Isometheptene (usually as isometheptene mucate) is a sympathomimetic amine sometimes used in the treatment of migraines and tension headaches due to its vasoconstricting properties; that is, it causes constriction (narrowing) of blood vessels (arteries and veins).[1][2] Along with paracetamol and dichloralphenazone, it is one of the constituents of Amidrine.

Chemistry

Isometheptene is a monounsaturated aliphatic secondary amine.

Mechanism of action

Isometheptene's vasoconstricting properties arise through activation of the sympathetic nervous system via epinephrine and norepinephrine. These compounds elicit smooth muscle activation leading to vasoconstriction by interacting with cell surface adrenergic receptors.[3]
