Which of the following formulations is NOT used for Ketoconazole?

Ketoconazole is an antifungal medication that is utilized in various formulations to treat fungal infections. The correct response identifies that an intravenous solution is not a formulation used for Ketoconazole. While Ketoconazole is available in several forms, such as topical creams for skin infections, gels for localized treatment, and shampoos specifically developed to treat dandruff and seborrheic dermatitis, the intravenous formulation is not part of its available delivery methods.

This limitation exists because intravenous Ketoconazole has been associated with hepatotoxicity and other safety concerns, leading to its decreased usage in preferred oral or topical forms. Therefore, the lack of an intravenous solution among the formulations available indicates a recognized safety profile, reflecting the reasons behind the choice of administration routes for this medication.
