First-Line Levofloxacin-Based Triple Therapy Versus Standard Bismuth-Based Quadruple Therapy for Eradication in Saudi Arabia: A Retrospective Single-Center Study.

Background And Aims: Antibiotic resistance in Saudi Arabia has led to decreased efficacy of conventional triple therapy for () eradication, prompting the development of alternative treatments like levofloxacin-based triple and bismuth-based quadruple therapies. However, comparative data regarding its efficacy are lacking. Therefore, this study's goal was to compare the efficacy of levofloxacin-based triple therapy with that of standard bismuth-based quadruple therapy as first-line regimens.
