What is metronidazole?

• A. Antiemetic
• B. Antibiotic
• C. Antifungal
• D. Antiparasitic

Answer: (B)

Metronidazole is an antibiotic. It belongs to the nitroimidazole class and is especially active against anaerobic bacteria and certain protozoa. It works by being taken up by these organisms and, once reduced in the anaerobic environment, forming reactive compounds that damage DNA and kill the microbe. In veterinary practice, it’s commonly used for anaerobic infections (like intra-abdominal or dental infections) and for protozoal infections such as Giardia. It is not an antiemetic and not a traditional antifungal agent. While it does have activity against some parasites, its primary and most reliable classification is as an antibiotic.
