Comparison of Potassium-Competitive Acid Blockers and Proton Pump Inhibitors in Patients With Gastroesophageal Reflux Disease: A Systematic Review and Meta-Analysis of Randomized Controlled Trials
Abstract
This meta-analysis evaluated the efficacy and safety of potassium-competitive acid blockers (PCABs) compared to proton pump inhibitors (PPIs) in treating gastroesophageal reflux disease (GERD). A comprehensive literature search was conducted across multiple databases, and 11 randomized controlled trials comparing PCABs with PPIs were included. The primary outcome was the healing of erosive esophagitis (EE), with secondary outcomes, including relief of heartburn symptoms and adverse events. The analysis included 11 studies and a pooled sample of 4,108 GERD patients. Results showed that PCABs were significantly more effective in healing EE compared to PPIs (OR: 1.67, 95% CI: 1.24-2.24, p<0.01). PCABs also demonstrated a higher rate of complete resolution of heartburn symptoms, although this difference did not reach statistical significance (OR: 1.43, 95% CI: 0.98-2.09, p=0.06). In terms of safety, there was no significant difference in adverse events between PCABs and PPIs (OR: 0.91, 95% CI: 0.79-1.04, p=0.18), including serious adverse events. The superior efficacy of PCABs can be attributed to their unique pharmacological properties, which allow for more rapid and potent acid suppression compared to PPIs. However, the long-term safety profile of PCABs, particularly newer agents, requires further investigation. The study was limited by the predominance of vonoprazan among the PCABs studied and the focus on patients with EE rather than non-erosive reflux disease. In…
