[10-day therapy of pityriasis versicolor with ketoconazole].

Apart from the standard treatment of pityriasis versicolor with selenium disulphide preparations, the 30-day-therapy with ketoconazole has been considered an alternative so far. According to our investigations, the duration of treatment may be shortened to ten days. After discontinuation of the drug, the fungal elements are reduced and finally disappear. This effect is attributed to the active substance being deposited in the sebaceous glands and secreted onto the skin. An influence of the product on phagocytosis is also discussed.
