Ketoconazole - Oral: Uses, Side Effects, Dosages - Verywell Health
What Is Ketoconazole? Ketoconazole is an orally prescribed medication used to treat certain fungal infections, mainly systemic (bloodstream) infections, and is approved for adults 18 and older. Ketoconazole is categorized within a class of antifungals called imidazoles and is used when other medications are unavailable or cannot be tolerated. This antifungal works by blocking a specific fungal protein called cytochrome P-450-mediated 14 alpha-lanosterol demethylase enzyme. This protein is responsible for turning lanosterol—a type of steroid—into ergosterol. Without ergosterol, the weakened fungal cell wall starts to fall apart. Ketoconazole tablets are only available as the ketoconazole generic version. Aside from tablets, ketoconazole as a primary ingredient is also available under varying brand names, specifically in the form of topical products, including shampoos, gels, creams, and foams.
