Mechanism of action for ergotamine? Use for migraine

- Ergotamine selectively binds and activates serotonin (5-HT) 1D receptors located on intracranial blood vessels,
including those on arterio-venous anastomoses, thereby resulting in vasoconstriction and reducing the blood flow in
cerebral arteries that may lead to relieve of vascular headaches.
- Ergotamine has a complex mechanism of action that involves a variety of receptors, including 5-HT-1B/1D, dopamine,
and alpha-adrenoreceptors. By activating 5HT-1B and 5HT-1D receptors on intracranial blood vessels, ergotamine induces
vasoconstriction and relief of migraine headaches.
- Ergotamine also inhibits norepinephrine uptake and stimulates alpha-adrenergic receptors at therapeutic doses, leading to
prolonged vasoconstriction.
