Bismuth for PCAB-based H. Pylori Eradication

Status Completed

Clinical Trial Summary

Tegoprazan is a new potassium-competitive acid blocker (PCAB) that has been clinically available since 2018 in South Korea. P-CAB is highly active drugs targeting H+, K+ -ATPase in the gastric acid secretion of parietal cells. The mechanism of action is different from that of PPIs. Conventional PPIs require 3-5 days to achieve maximal and steady-state gastric acid inhibition, whereas P-CAB increases the intragastric pH to nearly 7 within four hours. In Japan, H. pylori eradication success rates has increased by therapies using P-CAB than those using proton pump inhibitors, owing to the stronger acid suppression capability of P-CAB. Bismuth has long been used to treat peptic ulcer disease, dyspepsia, parasite infections, and infectious diarrhea. The antibacterial effects of bismuth include inhibition of protein and cell wall synthesis in H. pylori. The main role of bismuth is to increase the eradication rate by 30%-40% in resistant H. pylori strains.

Clinical Trial Description

The investigators aim to evaluate the success rate and adverse drug events of bismuth added to PCAB-based triple therapy as a first-line regimen for H. pylori infection. ;
