Which of the following medications is NOT considered an antifungal?

Azithromycin is an antibiotic, specifically a macrolide antibiotic, that is primarily used to treat bacterial infections, including respiratory tract infections, skin infections, and sexually transmitted diseases. It works by inhibiting bacterial protein synthesis, thereby preventing bacterial growth and replication.

In contrast, Fluconazole, Amphotericin B, and Voriconazole are all classified as antifungal agents. Fluconazole is a triazole antifungal that is effective against various fungal infections, especially those caused by Candida and Cryptococcus species. Amphotericin B is a polyene antifungal that is often used for severe fungal infections due to its broad spectrum of activity and is known for its potency against systemic mycoses. Voriconazole is also a triazole antifungal, particularly effective against Aspergillus species and other resistant fungi.

The distinction among these options highlights the different classes of medications and their specific targets in microbial pathogens, making Azithromycin the clear choice as the non-antifungal agent among the options provided.
