What Metronidazole is Used For?
Metronidazole is an antibiotic for various infections affecting different parts of the body.

How Does Metronidazole Work?
The efficacy of metronidazole lies in its ability to diffuse into the cytoplasm of anaerobic bacteria, where it undergoes activation and reduction. This transformation results in a short-lived nitroso free radical that interacts with DNA, causing structural damage, strand breakage, and eventual bacterial death. While metronidazole starts working quickly, noticeable symptom improvements can take a couple of days. It is essential to complete the prescribed course to ensure the complete eradication of the infection.
Warnings and Precautions of Metronidazole
