The efficacy of DFN-15 for pain control of migraine remains controversial. We conduct a systematic review and meta-analysis to explore the influence of DFN-15 versus placebo on pain control in migraine patients.
We search PubMed, Embase, Web of Science, EBSCO, and Cochrane Library databases through November 2019 for randomized controlled trials assessing the effect of DFN-15 versus placebo on pain control in migraine patients. This meta-analysis is performed using the random-effects model.
Three randomized controlled trials are included in the meta-analysis. Overall, compared with the control group in migraine patients, lasmiditan treatment shows a positive impact on pain freedom at 2 hours (risk ratio [RR], 1.96; 95% confidence interval, 1.61-2.40; P < 0.00001), headache response at 2 hours (RR, 1.40; 95% CI, 1.25-1.57; P < 0.00001), and pain freedom at 24 hours (RR, 1.87; 95% CI, 1.33-2.62; P = 0.0003), but has no obvious influence or no substantial impact on no or mild disability level (RR, 1.21; 95% CI, 0.97-1.52; P = 0.09) or nausea (RR, 2.42; 95% CI, 0.53-11.01; P = 0.25). In addition, lasmiditan seems to result in the increase in dizziness (RR, 7.33; 95% CI, 1.83-29.30; P = 0.005) and paresthesia (RR, 5.17; 95% CI, 2.08-12.86; P = 0.0004).
DFN-15 treatment may be effective and safe for pain control in migraine patients.
