Improvement in symptoms after H2-receptor antagonist-based therapy for eradication of H pylori infection.

Aim: To investigate the therapeutic effects of triple therapy combining lafutidine with clarithromycin and amoxicillin on H pylori infection and the resolution of gastroesophageal symptoms after eradication.

Methods: We conducted a randomized, multicenter, open-label controlled trial to compare the effectiveness of a triple therapy of lafutidine, clarithromycin, and amoxicillin (lafutidine group) with that of a triple therapy of lansoprazole, clarithromycin, and amoxicillin (lansoprazole group) in patients with H pylori infection. The study group comprised 22 patients with gastric ulcers and 18 patients with duodenal ulcers who had H pylori infection.
