Mechanism of action
Rabeprazole is a proton pump inhibitor that reduces gastric acid secretion, creating an environment where the three antibiotics (metronidazole, clarithromycin, and amoxicillin) can effectively penetrate and kill H. pylori. Metronidazole and clarithromycin are bactericidal agents that disrupt bacterial protein synthesis and DNA, while amoxicillin inhibits bacterial cell wall synthesis. The combination approach reduces antibiotic resistance.
