How Metrozn-400 Works
Metrozn-400 contains Metronidazole, which enters susceptible microorganisms and is converted into reactive compounds that damage their DNA and interfere with essential cellular processes. This action helps inhibit or kill susceptible anaerobic bacteria and certain protozoa.
Its effectiveness depends on the microorganism causing the infection. It is not effective against all bacteria and does not treat viral illnesses.
