OBJECTIVE: To assess the efficacy of a combined oral contraceptive (COC) containing 3 mg drospirenone (drsp) plus 20 microg ethinylestradiol (EE) administered in 24 days of active treatment followed by a four-day hormone-free interval (24/4 regimen) compared with placebo for the treatment of moderate acne vulgaris. METHODS:Healthy females (14-45 years old) with moderate facial acne were randomized to 3 mg drsp/20 microg EE 24/4 (n = 270) or placebo (n = 268) for six cycles. The secondary efficacy variables measured included change from baseline to endpoint (cycle 6) in individual lesion count for nodules, papules, pustules, open and closed comedones. RESULTS: There were significantly greater reductions in individual lesion counts from baseline to endpoint in the 3 mg drsp/20 microg EE group than in the placebo group (P < 0.05 from parametric model). CONCLUSION: The 3 mg drsp/20 microg EE COC administered in a 24/4 regimen significantly reduced acne lesions.
