Mechanism of action

Rabeprazole is a proton pump inhibitor that reduces gastric acid secretion, creating an inhospitable environment for H. pylori. Bismuth acts as a bactericidal agent that damages the bacterial cell wall and inhibits urease enzyme. Amoxicillin and clarithromycin are antibiotics that inhibit bacterial protein synthesis and cell wall formation, working synergistically to eliminate the pathogen.
