The authors present the results obtained in the treatment of pityriasis versicolor with Itraconazole, comparing two schemes of treatment, in an open trial: 200 mg daily, for 5 and 7 days. The clinical diagnosis was confirmed by Wood's light and mycologically, by direct examination. The patients were controlled 21 and 35 days after beginning the treatment. The evaluation of the results showed that both schemes were effective. At the second control, there was clinical and mycologic cure in 90% of the patients from the 5-day group and in 95% of the patients from the 7-day group. The tolerance was good: 2 patients from the 7-day group and 1 patient from the 5-day group showed side-effects. Since there was no significant difference between the two schemes of treatment, the authors recommend the shortest one, that is, 200 mg daily for 5 days.
