Core Tip

Core tip: This study aimed to evaluate the efficacy of the 14-d moxifloxacin-based triple therapy compared to the corresponding 7-d regimen for second-line Helicobacter pylori (H. pylori) eradication in South Korea. The H. pylori-eradication rates in the RAM-14 group were significantly higher compared to the RAM-7 group for both the intention-to-treat and per-protocol analysis. The high eradication rate, excellent compliance, and safety of the 14-d regimen suggest its potential suitability as an alternative to the standard bismuth-based quadruple therapy. The 14-d moxifloxacin-based triple therapy is a significantly more effective second-line eradication treatment than the 7-d alternative for H. pylori infection in Korean patients.
