The efficacy of the study drugs was evaluated by counting inflammatory lesions and non\u2010inflammatory lesions. Safety was evaluated based on adverse events, local skin tolerability scores and laboratory test values. In total, 458 subjects were included in the efficacy and safety analyses. The total lesion count, the efficacy end\u2010point, was similarly changed both in the 2.5% and 5% BPO groups over the course of the study. The median rates of reduction from baseline to week 12 were approximately 65%. Thereafter, the counts were maintained at a reduced level without increasing until week 52. The median rates at week 52 were approximately 80%. Similar trends were observed for inflammatory and non\u2010inflammatory lesion counts. Bacteriological evaluation indicated similar distribution of the minimum inhibitory concentration of each of the antibacterial drugs against <jats:italic>Propionibacterium acnes<\/jats:italic> between the values at baseline and at week 52, suggesting that long\u2010term use did not result in changes in the drug sensitivity. The incidence of adverse events was 84.0% in the 2.5% BPO group and 87.2% in the 5% BPO group. Many of the adverse events occurred within the first month and were mild or moderate in severity and transient. The results suggest that both 2.5% and 5% BPO gels are effective and safe for long\u2010term treatment of patients with acne vulgaris.<\/jats:p>","DOI":"10.1111\/1346-8138.13741","type":"journal-article","created":{"date-parts":[[2017,2,2]],"date-time":"2017-02-02T02:09:23Z","timestamp":1486001363000},"page":"635-643","source":"Crossref","is-referenced-by-count":12,"title":["Open\u2010label, randomized, multicenter, phase III study to evaluate the safety and efficacy of benzoyl peroxide gel in long\u2010term use in patients with acne vulgaris: A secondary publication"],"prefix":"10.1111","volume":"44","author":[{"given":"Makoto","family":"Kawashima","sequence":"first","affiliation":[{"name":"Department of Dermatology Tokyo Women's Medical University Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshitaka","family":"Nagare","sequence":"additional","affiliation":[{"name":"Medical Writing Group Data Science Department Maruho Co.
