5. Pharmacological properties
5.1 Pharmacodynamic properties

Pharmacotherapeutic (ATC) Classification: D01A C08

Ketoconazole is a synthetic imidazole-dioxalane derivative. It is a broad spectrum antifungal agent which inhibits the growth of common dermatophytes and yeasts by altering the permeability of the cell membrane:

Dermatophytes: Trichophyton rubrum, T. mentagrophytes, T.tonsurans, Microsporum canis, M. audouini, M. gypseum and Epidermophyton floccosum.

Yeasts: Candida albicans, C tropicalis, Pityrosporum ovale (Malassezia ovale) and Pityrosporum orbiculare (M. furfur).

5.2 Pharmacokinetic properties

Ketoconazole was not detected in plasma in 39 patients who shampooed 4-10 times per week for 6 months or in patients who shampooed 2-3 times per week for 3-26 months. Twelve hours after a single shampoo, hair samples taken from six patients showed that high amounts of ketoconazole were present on the hair; only about 5% had penetrated into the hair keratin. There were no detectable plasma levels after chronic shampooing twice weekly for two months with ketoconazole.
