Imigran is a medication classified as a selective serotonin receptor agonist. It works by binding to serotonin receptors in the brain, leading to vasoconstriction of blood vessels and reducing inflammation associated with migraines. Imigran is indicated for the acute treatment of migraine attacks with or without aura in adults. It is not used for the prevention of migraines. Clinical studies have shown that Imigran can provide relief from migraine symptoms such as headache, nausea, and sensitivity to light and sound. It is important to follow the dosage instructions as prescribed by a healthcare provider to maximize the effectiveness of Imigran.
