Imitrex, known by its generic name sumatriptan, is a medication commonly used to treat migraines and cluster headaches. It belongs to a class of drugs called triptans, which work by narrowing blood vessels in the brain and reducing substances involved in pain signaling.

The primary mechanism of Imitrex involves activating serotonin receptors (specifically 5-HT1B/1D receptors). This action constricts blood vessels around the brain, alleviating headache pain and associated symptoms such as nausea and sensitivity to light or sound.
