5-HT1F agonists

Abstract

5-Hydroxytryptamine (HT)/serotonin receptor agonism has been a long-recognized property of triptan medications, and more recently, the study and development of medications with selective binding to the 1F receptor subtype have been explored. While the exact mechanism contributing to decreased symptoms of an acute migraine attack remains unclear, selective 5-HT1F agonists have demonstrated clinical efficacy with lasmiditan as the only approved medication from this class to date. Lasmiditan lacks vasoconstrictive properties, giving it utility in specific patient populations in whom triptans should be avoided. Availability, central nervous system (CNS) side effects, and 8-hour driving restriction may affect its clinical use.
