What is Metronidazole primarily classified as?

Metronidazole is primarily classified as an antibiotic and antiparasitic agent. It is effective against certain types of bacteria and protozoa, making it particularly useful in treating infections caused by anaerobic bacteria and some protozoal infections, such as giardiasis and amoebic dysentery. This dual action allows metronidazole to be employed in various veterinary medicine scenarios, particularly in gastrointestinal and dental infections.

The classification of metronidazole as an antibiotic recognizes its role in inhibiting bacterial growth, while its classification as an antiparasitic highlights its effectiveness against specific parasites. This combination of properties distinguishes it from other medication types, such as antifungals, antivirals, and analgesics, which serve different therapeutic purposes.
