How does Metrogyl 400 mg work?
Metronidazole is a prodrug and it gets active only once it is in the body. It targets anaerobic organisms. Once inside the cells, the nitro group is enzymatically reduced into highly reactive cytotoxic intermediates. These reactive intermediates bind to and damage the microbe’s DNA. They cause DNA strand breakage, inhibit protein synthesis and trigger the degradation of existing nucleic acids resulting in microorganism death.
Dosage
Use as and when prescribed by the healthcare provider.
