Which antifungal is NOT used as a treatment for Candida infections?

Vancomycin is an antibiotic that is primarily effective against gram-positive bacteria, particularly Staphylococcus aureus and Streptococcus species. It works by inhibiting bacterial cell wall synthesis. However, it has no antifungal properties and does not target fungal infections, including those caused by Candida species. Therefore, vancomycin is not used in the treatment of Candida infections.

In contrast, the other medications listed are all antifungals. Amphotericin B is a broad-spectrum antifungal that is often used for serious fungal infections, including those caused by Candida. Nystatin is typically used for topical or oral candidiasis, and itraconazole is an azole antifungal commonly prescribed for various Candida infections. Each of these antifungals has a specific role and mechanism in treating fungal overgrowth or infection, unlike vancomycin, which is strictly an antibiotic.
