What is the primary use of Metronidazole?

Metronidazole is primarily classified as an anti-parasitic medication. It is effective in treating infections caused by certain parasites, as well as specific bacterial infections. This includes conditions like trichomoniasis, which is caused by the parasite Trichomonas vaginalis, and can also be used for amoebic dysentery caused by Entamoeba histolytica.

While metronidazole has antibiotic properties and is used to treat bacterial infections, particularly those caused by anaerobic bacteria, its primary mechanism is targeting parasites. It works by inhibiting nucleic acid synthesis in the pathogens, leading to cell death.

The other options focus on different types of infections: antifungals target fungi, antivirals are used for viral infections, and antibiotics generally refer to substances that kill or inhibit bacteria. However, metronidazole’s unique effectiveness against parasites is what makes it distinct in its primary use.
