Vonoprazan a novel potassium competitive acid blocker; another leap forward
Abstract
Introduction: The eradication rate of Helicobacter pylori (H.pylori) has decreased due to antibiotics resistance and inadequate acid suppression.Vonoprazan is a novel potassium-competitive acid blocker (P-CAB), which has a rapid and sustained acid inhibitory effect and may be more effective than conventional proton pump inhibitors (PPIs) in H. pylori eradication.Aim: to study the efficacy and safety of vonoprazan as a component of first-line H. pylori eradication treatment compared with conventional PPI-based therapy.Material and methods: This randomised (one to one) non-blinded study was conducted on 400 consecutive proven H. pylori infected patients, of whom 200 received vonoprazan-based triple therapy, while 200 patients received PPI-based triple therapy for 14 days.The study outcomes were evaluated as eradication rate and adverse events in both patient groups.Results: The eradication rate was 86% in the vonoprazan group and 74.5% in the PPI group.The vonoprazan eradication rate was significantly higher than that of PPIs (p = 0.004).There was no significant difference regarding adverse events between both patient groups.Conclusions: Vonoprazan-based therapy was more effective than PPI-based therapy as a first-line H. pylori eradication treatment.Vonoprazan was generally safe and well tolerated.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 200 participants or records.
