Ketoconazole is a synthetic antifungal medication that has been widely used for decades to treat various fungal infections. The drug works by inhibiting the production of ergosterol, a critical component of fungal cell membranes, thereby disrupting the cellular structure and function of the fungus. Ketoconazole is available in various formulations, including oral tablets, creams, shampoos, and foams, each designed for specific applications.

Ketoconazole is used to treat a range of systemic fungal infections, including:
- Blastomycosis: a rare fungal infection caused by inhaling spores of the fungus Blastomyces dermatitidis.
