Mechanism of action

Metronidazole is a nitroimidazole that disrupts bacterial DNA and is effective against anaerobic organisms and protozoa, while amoxicillin is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding penicillin-binding proteins. This combination is commonly used for polymicrobial infections where both aerobic and anaerobic coverage is needed, such as in H. pylori eradication or mixed bacterial infections.
