Optimal Dosing of Lasmiditan in the Management of Acute Migraine Attack: A Systematic Review and Meta-analysis.

Background: The current target of migraine treatment is focused on Triptans. Lasmiditan, a non-vasoconstrictive and highly selective 5HT receptor agonist is a novel therapeutic discovery for migraine for patients with cardiovascular (CV) risk factors or stable cardiovascular diseases and who fail to respond to the existing treatment.

Objective: To identify an optimal dosing of Lasmiditan 100 mg versus 200 mg for the treatment of acute migraine attacks in adult patients with cardiovascular risk factors.

Methods: Systematic searches were run in databases such as Cochrane Central Register of Controlled Trials (CENTRAL), Scopus, Google scholar, and PUBMED. Out of 83 study records identified, two studies were included for quantitative analysis.

Results: There was a significant headache pain freedom at 2 h [Odds Ratio (OR): 0.77; 95% Confidence interval (CI): 0.64-0.92] and sustained pain freedom at 24 h (OR): 0.75; 95% CI: 0.61-0.93] in patients taking Lasmiditan 200 mg compared to those taking Lasmiditan 100 mg. The results were statistically insignificant for parameters like most bothersome symptoms (MBS) free at 2 h, headache relief at 2 h, disability level at 2 h, and global impression of change at 2 h. A combined analysis of these parameters showed a remarkable difference between both the groups favoring Lasmiditan 200 mg [OR: 0.88; 95% CI: 0.81-0.95].

Conclusion: An oral dosing of Lasmiditan 200 mg is ideal for the treatment of acute migraine in adult patients with CV risk factors for attaining headache pain freedom at 2 h and sustained pain freedom at 24 compared to Lasmiditan 100 mg.
