Mechanism of action

Metronidazole is a nitroimidazole that generates reactive oxygen species in anaerobic bacteria, damaging their DNA. Azithromycin is a macrolide antibiotic that binds to the bacterial 50S ribosomal subunit, inhibiting protein synthesis. Together, they provide broad-spectrum coverage against both anaerobic and aerobic bacteria, commonly used in polymicrobial infections.
