Serotonin agonists migraine

Sumatriptan is a 5HT (serotonin) agonist indicated in the treatment of migraine. Sumatriptan causes vasoconstriction and must therefore be used with caution in patients with coronary heart disease, such as angina. Concurrent administration of the agonist, sumatriptan and antagonists, such as fluoxetine, which is a selective serotonin re-uptake inhibitor, leads to increased CNS toxicity. [Pg.120]

Qll Sumatriptan is a serotonin agonist (5-HTj agonist) that reduces the cerebral vasodilation which is believed to cause migraine headache. [Pg.137]

The etiology of migraine headaches is currently attributed to the neurovascular hypothesis, with the release of vasoactive neuropeptides and subsequent vasodilation of blood vessels. Serotonin plays an important role in migraine pathophysiology, and serotonin agonists have an important role in migraine treatment. [Pg.39]
