How Does Ketoconazole Work? 

Clotrimazole kills the fungus (yeast) that is the source of the infection. Clotrimazole kills fungus by causing holes in its cell membrane to emerge, allowing the components to escape. The fungus is killed, and the infection is treated (Müller, R.H., 2005).

Aim: In a double-blind, randomized study, the efficacy of two topical cream formulations containing Clotrimazole 1 percent and Ketoconazole 2 percent, respectively, were clinically evaluated for a 28-day treatment of interdigital tinea pedis in 106 patients.

Conclusion: Both Clotrimazole and Ketoconazole may successfully treat tinea pedis within 28 days of treatment. Once-daily Clotrimazole is similarly effective as twice-daily Ketoconazole, with favorable effects on the disease's most bothersome symptoms.
