Which drug is primarily used for treating fungal infections?

Amphotericin B is primarily used for treating fungal infections and is one of the most well-known antifungal medications. It acts by binding to ergosterol, a key component of fungal cell membranes, leading to increased permeability and ultimately cell death. This mechanism makes it effective against a wide range of fungi, particularly in severe and systemic infections caused by organisms such as Candida and Aspergillus species.

Fluconazole is also an antifungal medication and is used commonly for various fungal infections, particularly those caused by Candida species and in the treatment of cryptococcal meningitis. While it is effective, Amphotericin B is often reserved for more serious infections or cases where the patient is severely immunocompromised due to its potency and side effect profile.

Vancomycin is an antibiotic that primarily targets Gram-positive bacteria and is not effective against fungal infections. It is used primarily for serious infections caused by resistant strains of bacteria, such as MRSA (methicillin-resistant Staphylococcus aureus).

Azithromycin is an antibiotic used to treat a wide variety of bacterial infections and is not effective against fungi. It works by inhibiting bacterial protein synthesis but has no action against fungal pathogens.
