        ABSTRACT    OBJECTIVE:To systematically evaluate the efficacy and safety of Ubrogepant and Rimegepant in the treatment of
        acute migraine,and to provide evidence-based reference for the clinical treatment. METHODS:Retrieved from PubMed,Embase,
        Cochrane Library, CNKI, VIP, Wanfang database and Clinicaltrials. gov, randomized controlled trials (RCTs) about the
        Ubrogepant and Rimegepant(trial group)versus placebo(control group)in the treatment of acute migraine were collected during
        the inception to Jan. 2020. After literature screening and data extraction,quality assessment was performed using the bias risk
        assessment tool provided by the Cochrane system evaluator manual 5.1.0. Meta-analysis was performed by using Stata 16.0
        software. RESULTS:Eight RCTs with a total of 7 989 patients were included. The results of Meta-analysis showed that the
        proportion of patients who were free from pain at 2 h postdose in Ubrogepant group [RR=1.65,95%CI(1.38,1.98),P<0.001]
        and Rimegepant group [RR=1.69,95% CI(1.46,1.95),P<0.001],the proportion of patients who were free from the most
        bothersome symptom at 2 h postdose in Ubrogepant group [RR=1.35,95% CI(1.20,1.53),P<0.001] and Rimegepant
        group [RR=1.37,95%CI(1.24,1.51),P<0.001],and other secondary outcome indicators( i.e. the proportion of patients with
        pain relief at 2 h postdose,the proportion of patients with sustained freedom from pain from 2-24 h postdose,the proportion of
        patients with sustained pain relief from 2-24 h postdose,the proportion of patients without photophobia at 2 h postdose,the
        proportion of patients without phonophobia at 2 h postdose,the proportion of patients without nausea at 2 h postdose)were all
        significantly better than control group(P<0.05). In terms of safety,there was no statistical significance in the incidence of total
        ADR between Ubrogepant group and control group [RR=1.04,95%CI(0.87,1.25),P=0.646],but the incidence of total ADR in
        Rimegepant group were significantly higher than control group [RR=1.23,95% CI(1.01,1.50),P=0.043]. There was no
        statistical significance in other security indicators (i.e. incidence of nausea,dizziness,dry mouth,somnolence,urinary tract
        infection)in 2 groups(P>0.05). CONCLUSIONS:Ubrogepant and Rimegepant are effective in the treatment of acute migraine.
        Ubrogepant is safe,while Rimegepant may increase the incidence of ADR.
