Further information: Serotonin receptor agonist and Triptan § Mechanism_of_action

Frovatriptan is a serotonin receptor agonist, with high affinity for the 5-HT1B/1D receptors. It has no significant effects on the GABAA mediated channel activity and benzodiazepine binding sites. Frovatriptan inhibits excessive dilation of arteries that supply blood to the head.
