What is the first-line treatment for trichomoniasis?

• A. Metronidazole
• B. Penicillin
• C. Acyclovir
• D. Fluconazole

Answer: (A)

Trichomoniasis is caused by a protozoan parasite that responds to nitroimidazole antibiotics. Metronidazole is the first-line choice because it is highly effective against anaerobic protozoa; once inside the parasite, it is activated in the anaerobic environment and disrupts the organism’s DNA, causing death. This makes it the most reliable option to eradicate the infection. It’s commonly given as a single 2 g oral dose or 500 mg twice daily for 7 days. The other drugs target bacteria, viruses, or fungi and do not treat this protozoal infection.
