Study of oral Ketoconazole on recurrent & extensive Pityriasis Versicolor

Abstract

Several topical agents have been used for treating Pityriasis versicolor. But the main problem is recurrence. In this study 82 patients with recurrent and/or extensive from of infection were treated with oral Ketoconazole. 200 mg once daily for a maximum of 4 weeks. Seventeen patients have been infected for the first time and sixty five for the several times. The duration of disease in most cases (35.4%) were between 1-3 years. Out of 82 studied patients only 60 cases were referred for follow up. The clinical and mycological cure were seen in 54 cases (90%) after 15 days therapy. In other 6 patients after 15 days the lesions have not cured completely so the treatment was continued for other 2 weeks, but after that, only one of them referred to the clinic, which treatment extended with topical therapy.
