摘要

Background: Ketoconazole cream and adapalene gel are effective drugs against pityriasis versicolor. However, there are no reports on combination treatment with both compounds in pityriasis versicolor. Objective: To evaluate the efficacy and safety of combination therapy with adapalene 0.1% gel and ketoconazole 2% cream against pityriasis versicolor. Methods: Participants with pityriasis versicolor were randomly assigned to two groups: the combination group was treated with adapalene 0.1% gel and ketoconazole 2% cream once daily, and the monotherapy group received ketoconazole 2% cream twice daily. The treatment lasted 2 weeks in both groups. Outcomes were assessed at baseline and 1, 2 and 4 weeks after the initiation of treatment. Results: We noted clinically significant differences in total improvement rates between groups Weeks 1 and 2. A statistically significant difference was obtained Week 4. The treatment was well tolerated by all participants. Conclusions: The combination of adapalene 0.1% gel and ketoconazole 2% cream is effective and safe in the treatment of pityriasis versicolor. This therapeutic regimen was rapid, providing a valuable option for patients with pityriasis versicolor.
