How Does Ketoconazole Cream Work?

Ketoconazole inhibits fungal lanosterol 14-alpha-demethylase and reduces ergosterol synthesis. This disrupts normal fungal cell membrane structure and inhibits growth of susceptible dermatophytes and yeasts.

Who Is Treated With Ketoconazole Cream?

Ketoconazole cream 2 percent is used for tinea corporis, tinea cruris, and tinea pedis caused by susceptible dermatophytes, tinea versicolor caused by Malassezia furfur, cutaneous candidiasis, and seborrheic dermatitis. It is for topical dermatologic use and is not used in the eyes.

How Is Ketoconazole Cream Applied?

For cutaneous candidiasis, tinea corporis, tinea cruris, tinea pedis, and tinea versicolor, the cream is applied once daily to the affected area and surrounding skin. Candidiasis, tinea corporis, tinea cruris, and tinea versicolor usually use about two weeks of treatment, while tinea pedis uses six weeks. Seborrheic dermatitis uses application twice daily for four weeks or until clearing.

What Adverse Reactions Are Linked to Ketoconazole Cream?
