Single dose (400 mg) versus 7 day (200 mg) daily dose itraconazole in the treatment of tinea versicolor: a randomized clinical trial.

Abstract

Tinea (pityriasis) versicolor is a superficial fungal infection and one of the most commonly found pigmentary disorders of skin caused by the yeast Malassezia. Multiple topical as well as systemic therapies are available for treatment. Systemic therapies are used for extensive disease, frequent relapse or where topical agents have failed. The aim that translates the rationale of the study was to compare the efficacy, safety, tolerability and cost effectiveness of single dose 400mg versus 7 day 200 mg daily dose of itraconazole in the treatment of tinea versicolor. A clinical study was done to compare the efficacy of single dose (400 mg) of itraconazole and 7 day 200 mg daily dose of itraconazole in the treatment of extensive tinea versicolor. Total 60 patients (aged 18-50 years) were selected for the study during the period of June 2007 to May 2008 in the department of Dermatology of three different hospitals in Bangladesh. Cases having with extensive involvement, diagnosed clinically and confirmed by wood's lamp and KOH microscopy were taken. Patients were randomly allocated into equal groups. Group A was given single dose 400 mg itraconazole and Group B was given 7 day 200 mg daily itraconazole. Fifty three (88%) male and 7(12%) female were included in the study. The mean age of group A was 32.37+/-9 years and in group B 33.23+/-8 years. The mean duration of the disease in group A was 2.63+/-2 months and 2.76+/-2 months in group B. In group A clinical responders was found cure 22(73.33%) and improvement 5(16.33%) and in group B it was found cure 24(79.99%) and improvement 4(13.33%). The measure at the End point (EP1) equals to 90% response and in-group B it was found cure 24 (79.99%) and improvement 4(13.33%). (Here the End point EP2) equals to 93.33%. The EP clinical analysis however shows 91.66% response. Both single dose and 7 day daily dose of itraconazole can be effective in the treatment of tinea versicolor with extensive involvement but single dose appears to be better for improving compliance and decreasing the cost of treatment.
