Profiling lasmiditan as a treatment option for migraine
Introduction: In recent years, research into acute migraine treatment has aimed to develop molecules capable of inhibiting trigeminal pathways, mediated by agonism to 5-HT1F receptors in order to avoid the vasoconstrictive action due to the stimulation of 5-HT 1B/1D receptors. A novel migraine drug class, called ‘neurally acting anti-migraine agents’, has been developed for the management of acute migraine attacks. Lasmiditan is the only compound of this drug class that has been evaluated in Phase III clinical trials. Areas covered: This review discusses lasmiditan including its pharmacokinetics, pharmacodynamics, efficacy and safety profile. Original research and review articles, relative to the period 2010–2019, were included in the reviewed literature. Expert opinion: The most recent phase III trials have demonstrated the efficacy of lasmiditan for acute migraine treatment, even if compared only with placebo. Nevertheless, the low rate of cardiovascular side effects with lasmiditan might offer a potential therapeutic option for migraine patients with cardiovascular disorders. With the lack of data on lasmiditan’s pharmacokinetic features, several phase I clinical trials are still ongoing in order to evaluate half-life, metabolism, excretion and the potential production of active metabolites. Possible pharmacodynamic interaction with drugs acting on central nervous system should be evaluated in future studies.
