Acne is the most common skin disease, with a relative prevalence of 85%-100% among young individuals. It affects the cosmetic appearance of the patients provoking severe distress. A number of different topical treatments have been used for the treatment of acne. In this study, we investigated the efficacy and safety of the topical treatment with 5% benzoyl peroxide and 3% erythromycin gel in patients with papulopustular acne. One hundred and ninety-one patients with inflammatory acne completed the study. The patients included 54 males and 137 females, mean age 22.3 ± 8.1 years. Topical gel was applied on the face once daily for 3 months. The mean number of non-inflammatory and inflammatory lesions after 3 months of therapy decreased significantly with respect to baseline, with a mean percentage reduction of the non-inflammatory and inflammatory lesions by 42.2% and 57.5%, respectively. In conclusion, topical 5% benzoyl peroxide and erythromycin 3% as monotherapy is efficient for the treatment of papulopustular acne.
