Flutrimazole shampoo 1% versus ketoconazole shampoo 2% in the treatment of pityriasis versicolor. A randomised double-blind comparative trial.

摘要

Flutrimazole is an imidazole derivative that has been proven to be efficient in superficial skin fungal infections. The aim of this randomised double-blind study was to compare for the first time, the efficiency and safety of flutrimazole 1% shampoo versus ketoconazole 2% shampoo in the treatment of tinea versicolor. Study population consisted of 60 patients with pityriasis versicolor diagnosed clinically and through direct microscopy and culture. Patients were randomly assigned to two groups: one instructed to apply flutrimazole shampoo 1% and one instructed to apply ketoconazole shampoo 2% both on head and body for 14 days. Patients were re-evaluated 14 days after the end of treatment clinically and through direct microscopy and culture. Twenty-one of 26 patients (80.8%) in the ketoconazole and 22 of 29 patients (75.9%) in the flutrimazole group had both visual healing and negative mycological evaluation. Comparison of the response between the two groups with the Yates' corrected chi-square was foundstatistically not significant (chi(2) = 0.19, d.f. = 1, P = 0.91). None of the patients in the two groups reported any adverse effects. Fourteen (53%) patients in the ketoconazole group and 23 (79%) in the flutrimazole group assessed the shampoos as cosmetically acceptable regarding texture, smell and foam properties. Flutrimazole shampoo 1% appears to present efficacy comparable with ketoconazole 2% in the treatment of tinea versicolor.
