Metronidazole

Metronidazole is an antibiotic that is used to treat a wide variety of bacterial infections. It can also be used to treat certain parasitic infections. Metronidazole works by stopping the growth of bacteria and certain parasites. It is effective against a wide range of intestinal, facial and metabolic infections.

Uses for Metronidazole

Metronidazole is used to treat a wide range of bacterial and certain parasitic infections.

It can also be used to treat Clostridium difficile-associated diarrhea and pseudomembranous colitis.

Mechanism Of Action

Metronidazole works by inhibiting the growth of bacteria and certain parasitic organisms. It acts on DNA, the genetic material in the body which carries instructions to make proteins and enzymes necessary for cell growth.
