Nystatin, Ketoconazole, and Fluconazole are all classified as what type of agents?

Nystatin, Ketoconazole, and Fluconazole are classified as anti-fungal agents because they are specifically designed to target and eliminate fungal infections. Each of these medications has a different mechanism of action, which allows them to effectively treat a variety of fungal conditions.

Nystatin is primarily used for infections caused by yeast, particularly Candida species. It works by binding to ergosterol in fungal cell membranes, creating pores that lead to cell death.

Ketoconazole, which is an azole antifungal, interferes with the synthesis of ergosterol as well, disrupting the cell membrane and ultimately leading to the death of the fungus. It's used for a range of fungal infections, including those affecting the skin and systemic infections.

Fluconazole is another azole that is effective against a wide spectrum of fungal pathogens, particularly Candida, and is often preferred for certain systemic infections due to its good absorption and penetration into bodily tissues.

In contrast, the other options represent different classes of medications: anti-bacterial agents target bacteria, anti-viral agents are used to treat viral infections, and analgesic agents are used to relieve pain. This clarifies why the correct classification for Nystatin, Ketoconazole, and Fluconazole
