Adding Bismuth to Rabeprazole-based First-line Triple Therapy Does Not Improve the Eradication of Helicobacter Pylori

This randomized controlled study aimed to evaluate whether adding bismuth to the standard first-line triple therapy could improve the eradication rate of Helicobacter pylori (H. pylori). A total of 162 patients with H. pylori infection were randomly assigned to either the 7-day triple therapy group (n = 81) or the bismuth plus triple therapy group (n = 81). The triple therapy (RAK) contained the twice-daily dosage of rabeprazole 20mg, amoxicillin 1g and clarithromycin 500mg. In the RBAK group, bismuth subcitrate 360 mg twice daily was added to the RAK regimen.
