Ketoconazole

Ketoconazole is a synthetic antifungal drug used to prevent and treat skin and fungal infections, especially in immunocompromised patients such as those with AIDS. Due to its side-effect profile, it has been superseded by newer antifungals, such as fluconazole and itraconazole. Ketoconazole is sold commercially as an anti-dandruff shampoo, branded Nizoral®, by Janssen Pharmaceutica.
