Comparison of Lasmiditan 200 mg Versus 100 mg for Migraine Patients: A Meta-analysis of Randomized Controlled Studies.

INTRODUCTION: The ideal dose of lasmiditan for migraine is not clear. This meta-analysis aims to compare the efficacy of lasmiditan 200 mg versus 100 mg for migraine patients. METHODS: We have searched several databases including PubMed, Embase, Web of Science, EBSCO, and Cochrane Library Databases and selected the randomized controlled trials comparing the efficacy of lasmiditan 200 mg versus 100 mg for migraine patients. This meta-analysis was conducted using the random-effect model. RESULTS: Five randomized controlled trials were included in this meta-analysis. Compared with lasmiditan 100-mg group in migraine patients, lasmiditan 200-mg group was associated with substantially increased pain free at 2 hours (odds ratio [OR], 1.27; 95% confidence interval [CI], 1.12-1.44; P = 0.0002) and pain free at 24 hours (OR, 1.31; 95% CI, 1.08-1.60; P = 0.007) but demonstrated no obvious impact on pain relief at 2 hours (OR, 1.02; 95% CI, 0.91-1.16; P = 0.72) or MBS free at 2 hours (OR, 0.94; 95% CI, 0.77-1.14; P = 0.52). In addition, the incidence of adverse events was higher in lasmiditan 200-mg group than that in lasmiditan 100-mg group (OR, 1.29; 95% CI, 1.15-1.45; P < 0.0001). CONCLUSIONS: Lasmiditan 200 mg is better for the treatment of migraine patients than lasmiditan 100 mg.

The efficacy and safety of fluoxetine versus placebo for stroke recovery: a meta-analysis of randomized controlled trials.

BACKGROUND: Fluoxetine is one of the selective serotonin reuptake inhibitors that can improve motor and function recovery after a stroke. Several randomized controlled trials (RCTs) have investigated the efficacy and safety of fluoxetine compared to placebo in post-stroke recovery. However, the results are still controversial. AIM: This meta-analysis aimed to provide an updated analysis of the efficacy and safety of fluoxetine versus placebo in post-stroke recovery. METHOD: RCTs were searched from electronic databases of PubMed, Embase, Clinical Trials, and the Cochrane Central Register of Controlled Trials from inception until July 2022. Google Scholar and the reference lists of included studies were screened to identify additional studies. Outcomes were analyzed using risk ratios (RR) and mean differences (MD) with 95% confidence intervals (CI). RESULTS: Fourteen RCTs (6584 patients) were included. The fluoxetine group showed a significantly higher Fugl-Meyer motor scale (FMMS) score than the placebo group (MD 15.93, 95%CI 9.76-22.7, P < 0.01). No significant differences were observed in the modified Rankin Scale (mRS) (mRS ≤ 2, RR 1.00, 95%CI 0.88-1.15, P = 0.95), the Barthel index (MD 12.11, 95%CI - 0.71 to 24.92, P = 0.06), and the National Institutes of Health Stroke Scale scores (MD - 0.19, 95%CI - 0.43 to 0.04, P = 0.1) between the two groups. The fluoxetine group showed a lower rate of depression or anxiety than the placebo group (RR 0.67, 95% CI 0.49-0.92, P < 0.05). There were no significant differences between the groups regarding gastrointestinal adverse reactions (P > 0.05), drowsiness (P > 0.05) or insomnia (P > 0.05). CONCLUSION: Fluoxetine improved FMMS and reduced anxiety and depression. More well-designed and large sample-size RCTs are required to further analyze the efficacy of fluoxetine in post-stroke recovery.
