Lasmiditan for acute treatment of migraine.

Lasmiditan, a selective 5-HT1F receptor agonist, is a harbinger for the novel ditan class of medications for acute migraine treatment. Lasmiditan activates 5-HT1F receptors on presynaptic trigeminal nerve terminals, which impedes the release of calcitonin gene-related peptide (CGRP) from trigeminal nerve endings and thereby suppresses activation of the trigeminovascular system. Notably, lasmiditan does not result in vasoconstriction, making lasmiditan a migraine-specific acute treatment option for those with cardiovascular risk factors. However, lasmiditan does have centrally mediated side effects. This review will discuss the background of lasmiditan development, its preclinical pharmacology, safety, drug interactions and indications for use.
