Comparative efficacy of ketoconazole and fluconazole in the treatment of pityriasis versicolor: a one year follow-up study.
Pityriasis versicolor can be treated by a single or multiple dosage regime of ketoconazole as well as by fluconazole. The therapeutic efficacy of these two drugs has not been compared. One hundred and eighty patients with moderate to extensive pityriasis versicolor confirmed by KOH and Wood's lamp examination were randomly assigned to one of the four oral antifungal regimes: Ketoconazole 400 mg single dose (Category I), Ketoconazole 200 mg daily for 10 days (Category II), Fluconazole 400 mg single dose (Category III) or Fluconazole 150 mg per week for 4 weeks (Category IV). Follow up was done at 2 and 4 weeks and then at 3, 6 and 12 months after the treatment in each group. KOH and Wood's lamp examinations were repeated each time. After four weeks of treatment, clinical cure was observed in 66.6% (Category I), 73.3% (Category II), 80% (Category III) and 59.9% (Category IV) of patients. Mycological cure after four weeks of treatment was observed in 53.3% (Category I), 73.3% (Category II), 82.2% (Category III) and 64.4% (Category IV) of patients. After twelve months of follow-up, maximum relapses were observed with Category I. No relapse was seen in Category III patients. The time period of relapse varied from three to ten months. In conclusion, single dose 400 mg oral fluconazole provided the best clinical as well as mycological cure rate with no relapse during twelve months of follow-up.
