Which drug class destroys protozoa?

• A. Anti-impotence
• B. Anti-infective
• C. Antimigraine
• D. Antiprotozoal

Answer: (D)

The key idea is recognizing the specific drug class that targets and kills protozoa. Protozoa are single-celled parasites, and drugs labeled antiprotozoal are the ones designed to destroy them or inhibit their growth. This category directly describes agents used to treat protozoal infections such as malaria, amoebiasis, giardiasis, and trichomoniasis, often by attacking parasite-specific metabolic pathways or structures.

While an anti-infective is a broad umbrella for agents against various pathogens, including bacteria, viruses, fungi, and parasites, the precise term that denotes destruction of protozoa is antiprotozoal. The other options describe completely different therapeutic roles (anti-impotence for erectile dysfunction and antimigraine for migraine relief), which do not pertain to protozoal treatment.
