In order to increase eradication rates, vonoprazan, a novel potassium-competitive acid blocker, has been used in Helicobacter pylori eradication therapy.


To summarise the results of the efficacy of vonoprazan-based triple therapy, helping clinicians to better understand the benefit of vonoprazan in the treatment of H. pylori infection.


We conducted a systematic literature search on MEDLINE, EMBASE, and the Cochrane Library using the primary keywords "vonoprazan," "takecab", "TAK-438," "potassium," "competitive," "potassium-competitive," "Helicobacter," and "pylori." Studies were included if they evaluated the eradication rate between the vonoprazan-based and proton pump inhibitor (PPI)-based triple therapies.


Ten studies and 10 644 patients were evaluated. The crude H. pylori eradication rate determined by intention-to-treat analysis was 87.9% and 72.8% in the vonoprazan-based triple therapy and PPI-based triple therapy respectively. The eradication rate of the vonoprazan-based triple therapy was superior to that of the PPI-based triple therapy (pooled risk ratio [RR] [95% confidence interval (CI)]=1.19 [1.15-1.24]) In addition, there was no significant difference in dropout rate due to adverse event between the regimens (pooled RR of the vonoprazan-based triple therapy [95% CI]=0.69 [0.23-2.03]). The incidence of any adverse events also did not differ between the regimens (pooled RR [95% CI]=1.02 [0.78-1.34]).


The vonoprazan-based triple therapy showed superior efficacy in terms of H. pylori eradication as compared to the PPI-based triple therapy. In addition, the vonoprazan-based triple therapy showed comparable tolerability and incidence of adverse events.
