Ketoconazole cream is an azole antifungal drug. It belongs to the same family of drugs as fluconazole (Diflucan), miconazole (Micatin, Monistat), and itraconazole (Sporanox). Ketoconazole prevents growth of several types of fungi by preventing production of the membranes that surround fungal cells. Ketoconazole cream is prescribed to treat fungal infections such as ringworm, jock itch, athlete's foot, dandruff, and tinea versicolor.

Clotrimazole cream is an antifungal medication related to fluconazole (Diflucan), ketoconazole (Nizoral), itraconazole (Sporanox), and miconazole (Micatin, Monistat). It prevents growth of several types of fungi by interfering with the production of the membrane that surrounds fungal cells. It is used topically on the skin or inserted vaginally to treat local fungal infections due to Candida albicans, including vaginal yeast infections, tinea versicolor, tinea pedis ("athlete's foot"), tinea cruris ("jock itch"), or tinea corporis (ringworm).
