Migraine, a chronic neurological disorder, imposes a significant burden on individuals and healthcare systems globally. This systematic review and meta-analysis evaluated the efficacy and safety of atogepant in preventing episodic migraine (EM) in adults. A systematic search was conducted in four major databases (PubMed, Scopus, Web of Science, and Cochrane CENTRAL) up to June 2024. The inclusion criteria targeted randomized controlled trials (RCTs) comparing atogepant to placebo or standard care in patients with EM. Statistical analyses were performed using Review Manager (RevMan) software. Four RCTs with 2,018 patients receiving atogepant and 761 patients receiving placebo or standard care were included. Atogepant significantly reduced monthly migraine days compared to placebo at 10 mg daily (mean difference [MD], –1.16 days; 95% confidence interval [95% CI], –1.60 to –0.73), 30 mg daily (MD, –1.15 days; 95% CI, –1.64 to –0.66), 60 mg daily (MD, –1.48 days; 95% CI: –2.36 to –0.61 days), 30 mg twice daily (MD, –1.30 days; 95% CI, –2.17 to –0.43), and 60 mg twice daily (MD, –1.20 days; 95% CI, –1.90 to –0.50). A ≥50% reduction in migraine days was frequently significantly achieved with atogepant across all dosages. Atogepant was generally well tolerated, though it was associated with higher incidence rates of constipation and nausea compared to placebo. Atogepant is an effective and well-tolerated option for preventing EM, offering patients a noninvasive oral alternative to injectable therapies. Further research is warranted to explore its long-term safety and efficacy in diverse patient populations and refine its role in this field.
