Which antibiotic is considered the treatment of choice for trichomoniasis?

Metronidazole is the antibiotic of choice for treating trichomoniasis, and it is commonly known by its brand name, Flagyl. This medication is effective against the Trichomonas vaginalis parasite, which is responsible for the infection. Metronidazole works by inhibiting nucleic acid synthesis, ultimately leading to the death of the organism. It is usually administered either orally or as a topical gel, making it versatile for treatment.

The use of Metronidazole has been extensively studied and supported by clinical guidelines, which establish it as the standard for managing trichomoniasis. The option referring to Flagyl aligns with this, as it is simply another name for Metronidazole, therefore reinforcing that this medication is indeed the appropriate choice for treatment.
