Lansoprazole, levofloxacin and amoxicillin triple therapy vs. quadruple therapy as second‐line treatment of resistant <i>Helicobacter pylori</i> infection

Abstract

Lansoprazole, amoxicillin plus levofloxacin second-line therapy is comparable with quadruple therapy in efficacy. Subjects, especially those with dual resistance to metronidazole and clarithromycin, may consider levofloxacin-based therapy for levofloxacin-sensitive strains.
