Pharmacological action of

Antimigraine preparation. A specific selective agonist of serotonin 5HT1B-1D receptors (5-hydroxytryptamine-1-like) located primarily in the smooth muscles of the walls of the blood vessels of the brain. Stimulation of 5HT1 receptors leads to selective narrowing of blood vessels in the carotid artery system and a decrease in the processes of neurogenic inflammation, without having a significant effect on cerebral blood flow. In addition, it has been experimentally established that sumatriptan inhibits trigeminal nerve activity.

It is believed that these effects help to reduce the severity of pain in migraines.

Clinical effect is observed 30 minutes after oral administration of the drug.
