Imidazoles and benzoyl peroxide: a comparative trial of two treatment schedules.

A double-blind, split-face, self-controlled pilot trial was designed for comparing the therapeutical effect of (a) combination of 2% miconazole nitrate and 5% benzoyl peroxide applied twice daily and (b) topical application of 1% isoconazole nitrate in the morning followed in the evening by 5% benzoyl peroxide. There were no clinically relevant differences between both treatment regimes. These results are interpreted in terms of bioavailability of the active substances.
