Description and Uses

Almotriptan is an agonist of the serotonin (5-HT) receptor subtypes 5-HT_1B and 5-HT_1D (IC₅₀s = 12 and 13 nM, respectively, in a radioligand binding assay). It is selective for human 5-HT_1B and 5-HT_1D receptors over rat 5-HT_1A and human 5-HT_2A and 5-HT₄ receptors (IC₅₀s = 0.85, 25.1, and 140 μM, respectively). Almotriptan induces contractions in isolated canine saphenous veins (EC₅₀ = 394 nM) but not isolated rabbit renal or mesenteric arteries. It increases carotid vascular resistance in anesthetized cats (ED₁₀₀ = 11 μg/kg, i.v.) without increasing blood pressure or heart rate. Formulations containing almotriptan have been used in the treatment of migraine headaches.
