Used primarily in the treatment of migraine headaches, this compound functions as a selective serotonin receptor agonist, specifically targeting 5-HT1B and 5-HT1D receptors. It helps relieve migraine symptoms by constricting dilated blood vessels in the brain and reducing inflammation. As an active metabolite of almotriptan, it contributes to the overall efficacy of the parent drug in acute migraine management. Its pharmacological action supports pain relief, reduction of nausea, and decreased sensitivity to light and sound during migraine attacks. Due to its mechanism, it is not intended for preventive use but rather for acute intervention.
