Lasmiditan, sold under the brand name Reyvow, is a medication used for the acute (active but short-term) treatment of migraine with or without aura (a sensory phenomenon or visual disturbance) in adults.[2] It is not useful for prevention.[2] It is taken by mouth.[2]

Common side effects include sleepiness, dizziness, tiredness, and numbness.[3][4]

Lasmiditan was approved in the United States in October 2019[3] and became available in February 2020.[5] It was developed by Eli Lilly.[3] The U.S. Food and Drug Administration (FDA) considers it to be a first-in-class medication.[6]


Mechanism of action

Lasmiditan is a serotonin receptor agonist that, like the unsuccessful LY-334,370, selectively binds to the 5-HT1F receptor subtype. A number of triptans have been shown to act on this subtype as well, but only after their affinity for 5-HT1B and 5-HT1D has been made responsible for their anti-migraine activity.[7] The lack of affinity for these receptors might result in fewer side effects related to vasoconstriction compared to triptans in susceptible people, such as those with ischemic heart disease, Raynaud's phenomenon or after a myocardial infarction,[8] although a 1998 review has found such side-effects to rarely occur in people taking triptans.[9][10]

Adverse effects

There is a risk of driving impairment while taking lasmiditan. People are advised not to drive or operate machinery for at least eight hours after taking lasmiditan, even if they feel well enough to do so. People who cannot follow this advice are advised not to take lasmiditan. The drug causes central nervous system (CNS) depression, including dizziness and sedation. It should be used with caution if taken in combination with alcohol or other CNS depressants.[2]


Lasmiditan was discovered by Eli Lilly and Company and was then relicensed to CoLucid Pharmaceuticals in 2006, until CoLucid was bought by Eli Lilly in 2017, to allow Eli Lilly to reacquire the drug's intellectual property.[11] The drug is protected by patents until 2031.[12]

Phase II clinical trials for dose finding purposes were completed in 2007, for an intravenous form[13] and in early 2010, for an oral form.[14] Eli Lilly submitted a new drug application to the U.S. Food and Drug Administration (FDA) in November 2018.[15]

Three Phase III clinical trials were completed. The SPARTAN trial compared placebo with 50, 100, and 200 mg of lasmiditan.[16] SAMURAI compared placebo with 100 and 200 mg doses of lasmiditan. GLADIATOR is an open-label study that compared 100 and 200 mg doses of lasmiditan in subjects that received the drug as part of a prior trial.[17]

Topline results from the SPARTAN trial showed that the drug induced met its primary and secondary endpoints in the trial. The primary result showed a statistically significant improvement in pain relief relative to placebo 2 hours after the first dose. The secondary result showed a statistically significantly greater percentage of subjects were free of their most bothersome symptom (MBS) compared with placebo at two hours following the first dose.[18]

The FDA approved lasmiditan primarily based on data from two clinical trials, Trial 1 (# NCT02439320) and Trial 2 (#NCT02605174) of 4439 subjects with migraine headaches with or without aura.[19] Trials were conducted at 224 sites in the United States, the United Kingdom, and Germany.[19]

The FDA approved the drug in October 2019.[19] However, as of October 2019, the drug was awaiting Drug Enforcement Administration (DEA) scheduling before it was made available in the United States.[20] It was placed into Schedule V in January 2020.[21][1]


Lasmiditan is delivered in 50 & 100 mg tablet form.[22]
