Background and Aim: Up to 40% of gastroesophageal reflux disease (GERD) patients experience inadequate symptom relief with a proton pump inhibitor (PPI), termed PPI-resistant or refractory GERD. Vonoprazan, a potassium-competitive acid blocker, has better efficacy than PPI in suppressing gastric acid secretion. This meta-analysis summarizes the efficacy and safety of vonoprazan for treating PPI-resistant GERD (both erosive esophagitis [EE] and non-erosive reflux disease [NERD]). Methods: Four electronic databases (Medline, Embase, SCOPUS, and CENTRAL) were searched for studies indexed until August 1, 2023. Both observational studies and clinical trials assessing the efficacy and safety of vonoprazan in PPI-resistant GERD were included. Efficacy outcomes included healing and maintenance rates of EE and improvement of the Frequency Scale for Symptoms of GERD (FSSG) scores. Serious adverse events (SAEs) were considered a safety outcome. The modified Newcastle-Ottawa Scale (NOS) was used to assess study quality. Results: Twelve studies were included in this meta-analysis. Healing rates of PPI-resistant EE with vonoprazan 20 mg were 91.7% (95% CI 86.8–94.8%) and 88.5% (95% CI 69.7–96.2%) at weeks 4 and 8, respectively. For healed PPI-resistant EE, the overall maintenance rates with vonoprazan 10 mg were 82.6% (95% 61.2–95.0%) at week 8, 86.0% (95% CI 72.1–94.7%) at week 24, and 93.8% (95% CI 69.8–99.8%) at week 48. FSSG scores were improved in 74.6% (95% CI 65.8–81.7%) and 51.9% (95% CI 37.8–65.7%) of patients at weeks 4 and 8. Overall, no SAE was reported. Conclusion: Vonoprazan demonstrated high efficacy in the healing and maintenance of PPI-resistant EE and moderate efficacy for the improvement of FSSG score. Vonoprazan was well tolerated in PPI-resistant GERD patients. © 2024 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.
