[A new drug combination for the topical treatment of acne. Miconazole 2% + benzoyl peroxide 5% versus benzoyl peroxide 5%--a double-blind study].

A double-blind, controlled clinical trial with 60 patients was employed in order to study the relative merits of two treatment schedules in acne vulgaris. One therapy comprised the topical application of a cream containing a combination of miconazole 2% and benzoylperoxide 5% (Acnidazil, Janssen) twice a day. In the other therapy, we applied a cream containing only benzoylperoxide 5%. Both groups of patients showed large and statistically significant reduction in the number of comedones, papules, and pustules during 12 weeks of therapy. Acnidazil, however, was found to have definitely better therapeutical results than benzoylperoxide alone: The lesions improved significantly faster, tolerance was better, and the patients overall evaluation clearly favored Acnidazil. 86,2% of the patients treated with Acnidazil rated the results good to very good, in contrast to 63% of the patients treated with benzoylperoxide only (p = 0.037).
