Solubilized benzoyl peroxide versus benzoyl peroxide/clindamycin in the treatment of moderate acne. [Journal Article, Research Support, Non-U.S. Gov't]
J Drugs Dermatol 2008 Jun; 7(6):534-8.
BACKGROUND: Benzoyl peroxide (BPO) is poorly soluble. A solubilized formulation of BPO has been developed to maximize its bioavailability and enhance follicular penetration.
METHODS: Patients with acne vulgaris were randomly assigned to receive solubilized BPO 5% gel on one side of the face and a BPO 5%/clindamycin 1% combination product on the contralateral side, twice daily for 4 weeks.
RESULTS: Of 23 patients enrolled, 100% completed the study. Reductions in lesion count with the solubilized BPO gel were at least as great as with BPO/clindamycin--and significantly greater (P< or =.05) for noninflammatory lesions at week 1 and inflammatory lesions at week 4. Both regimens were generally well tolerated and patient satisfaction was comparable.
CONCLUSIONS: Solubilized BPO 5% gel monotherapy offers significantly greater efficacy, and comparable patient satisfaction, compared with BPO/clindamycin. The early reduction in lesion counts observed with the solubilized BPO gel in the absence of an antibiotic is clinically relevant.
