Overview

Ergotamine is an ergot alkaloid and vasoconstrictor used primarily for the acute treatment of vascular headaches, including migraine and cluster headaches. It acts as a partial agonist or antagonist at multiple receptor types, notably serotonergic (5-HT1B, 5-HT1D), dopaminergic, and adrenergic receptors. Its antimigraine effect is mainly due to constriction of intracranial extracerebral blood vessels via 5-HT1B receptor activation and inhibition of trigeminal neurotransmission at 5-HT1D receptors. Ergotamine also has potent activity at alpha adrenergic receptors and can stimulate uterine smooth muscle. It is not intended for daily use or for non-migraine headache types[1][2][3][6].
