Is combined oral and topical therapy better than oral therapy alone in patients with moderate to moderately severe acne vulgaris? A comparison of the efficacy and safety of lymecycline plus adapalene gel 0.1%, versus lymecycline plus gel vehicle.

This multicenter, randomized, investigator-blinded study compared the efficacy and tolerability of a combination of lymecycline 300 mg/day orally and adapalene topical gel 0.1% (n = 118) to lymecycline 300 mg/day orally plus vehicle gel (n = 124) in patients with moderate to moderately severe acne vulgaris with both inflammatory and noninflammatory lesions. The primary efficacy end point, total lesion count at end point (last observation carried forward), showed a statistically significant difference in favor of the lymecycline plus adapalene group (P =.
