Mechanism of action

N-acetylcysteine acts as a mucolytic agent that breaks down biofilm and reduces mucus viscosity, improving antibiotic penetration. The PPI (proton pump inhibitor) reduces gastric acid, creating a more favorable pH environment for antibiotic activity and reducing acid-related damage. Amoxicillin and clarithromycin are bactericidal antibiotics that directly target and kill H. pylori cells.
