ObjectiveTo systematically evaluate the efficacy and safety of Rimegepant in the treatment of acute migraine.MethodsThe databases of CNKI， Wanfang and VIP database， PubMed， Embase， Cochrane Library， ClinicalTrials were searched to collect relevant literature on the treatment of Rimegepant in acute migraine. The pain freedom and Most Bothersome Symptom （MBS） freedom 2 hours after medication were the primary outcome indicators， and the other 11 indicators including pain relief 2 hours after medication were the secondary outcome indicators. The Meta-analysis was performed using RevMan 5.3， and the quality of evidence was evaluated using GRADE Profiler 3.6 for outcome indicators.ResultsA total of 4 randomized controlled studies involving 3 827 patients， including 1 840 patients in the experimental group and 1 987 patients in the control group. Meta-analysis results showed that， in terms of effectiveness， compared with the control group， the proportion of patients in the Rimegepant group who were painless 2 hours after medication （RR=1.67， 95 % CI： 1.44~1.94， P<0.01）， MBS free 2 hours after medication （RR=1.37， 95% CI： 1.24~1.51， P<0.01） and pain relief （RR=1.33， 95% CI： 1.25~1.41， P<0.01）， pain relief lasting 2~24 hours after medication （RR=1.59， 95% CI： 1.46~1.74， P<0.01）， pain relief lasting 2~48 hours after medication （RR=1.57， 95% CI： 1.42~1.74， P<0.01）， painless 2~24 hours after medication （RR=2.27， 95% CI： 1.62~3.20， P<0.01）， painless 2~48 hours after medication （RR=2.14， 95% CI： 1.52~3.02， P<0.01）， and no fear of light （RR=1.47， 95% CI： 1.32~1.64， P<0.01） and no fear of sound 2 hours after medication （RR=1.40， 95% CI： 1.19~1.64， P<0.01） was higher， the differences were statistically significant. In terms of safety， the proportion of patients with nausea （RR=1.70， 95% CI： 0.95~3.02， P=0.07）， urinary tract infection （RR=1.81， 95% CI： 0.84~3.91， P=0.13）， dizziness （RR=1.14， 95% CI： 0.49~2.63， P=0.77） or elevated transaminase （RR=0.76， 95% CI： 0.45~1.27， P=0.29） showed no statistically significant differences between the Rimegepant group and the control group. Based on GRADE criteria， evidence for Rimegepant in the treatment of acute migraine was of high or moderate quality.ConclusionRimegepant is effective for acute migraine， and the toxic effects are tolerable.
