Topical metronidazole gel. Use in acne vulgaris

Two percent metronidazole and 5% benzoyl peroxide cream was evaluated in four clinical trials. It could be shown that this test cream was significantly better than 5% benzoyl peroxide jelly alone, and significantly better than a placebo cream. It was also shown that 2% metronidazole and 5% benzoyl peroxide cream was equal to systemic oxytetracycline therapy. The advisability of the combination of metronidazole and benzoyl peroxide was simultaneously discussed.
