A comparison of efficacy and safety of potassium‐competitive acid blocker and proton pump inhibitor in gastric acid‐related diseases: A systematic review and meta‐analysis

Potassium-competitive acid blocker (PCAB) is a recent alternative to proton pump inhibitor (PPI) for potent acid suppression. The current systematic review and meta-analysis aimed to compare the efficacy and safety of PCAB versus PPI in treating gastric acid-related diseases.
