Mechanism of action

Lansoprazole is a proton pump inhibitor that reduces gastric acid secretion, creating an environment where antibiotics are more effective. Amoxicillin and clarithromycin are bactericidal and bacteriostatic antibiotics, respectively, that target H. pylori cell wall and protein synthesis. Together, this triple therapy achieves high eradication rates by combining acid suppression with dual antibiotic coverage.
