The efficacy of levofloxacin‐based sequential regimen to eradicate Helicobacter pylori infection

Infection with Helicobacter pylori is globally prevalent. It is a chronic infection, standard treatment of which includes two antibiotics, amoxicillin and clarithromycin, plus a proton pump inhibitor used for 1 or 2 weeks. However, owing to increased resistance in our country, definitive eradication of H pylori is difficult. We conducted this study to evaluate the efficacy of a regimen using levofloxacin for successful eradication of H pylori infection.
