How does metronidazole work?
Metronidazole is an antiprotozoal and anaerobic antibacterial agent. When administered systemically via oral tablets or injection, metronidazole works by inhibiting bacterial DNA synthesis hence preventing the replication of bacteria. However the mechanisms by which topical metronidazole works in reducing inflammatory lesions of rosacea are unknown. Possible mechanisms of action include antibacterial and/or anti-inflammatory effects.
