BACKGROUND: Used as individual agents, topical antibiotics and benzoyl peroxide are known to be effective in treatment of acne. Clindamycin phosphate 1% with benzoyl peroxide 5% (CDP/BPO) is a new combination gel, made by rationale, in that combination drug is more effective than either ingredients used alone. Adapalene 0.1% (ADA) is the third-generation retinoid, shown to be as effective as other topical retinoid with well tolerability. OBJECTIVES: To compare the efficacy and tolerability in combination of CDP/BPO in comparison with ADA in Asian patients with mild to moderate acne vulgaris. METHODS: Total of 69 patients, including 31 patients for CDP/BPO group and 38 for ADA group, with mild to moderate acne vulgaris were enrolled for a 12-week prospective, randomized, open-label comparative study of topical agents. Efficacy was assessed by lesion counts, acne grading system, and global improvement. Adverse events were also evaluated in scale of 0 (none) to 3 (severe). RESULTS: Both CDP/BPO and ADA were effective in reducing lesion counts and acne severity scale and showed significant global improvement. However, CDP/BPO offered greater efficacy against inflammatory lesions than ADA. Both drugs were well tolerated with minimal adverse drug reactions. CONCLUSION: Combination formulation of CDP/BPO and ADA were shown to be both effective in decreasing total, inflammatory, and non-inflammatory lesion counts along with well tolerability in Asian patients with mild to moderate acne vulgaris.
