The purpose of this article is to review the effectiveness of the therapeutic use of topical corticosteroids to atopic dermatitis based on the information derived from randomized controlled trials (RCTs) of which level of evidence is 2b or above. More than ten kinds of topical corticosteroids were assessed by RCTs with placebo and most of them showed their effectiveness. Many RCTs about topical corticosteroids versus topical corticosteroids were published and showed significant improvement in subject after 1-6 weeks of use. Six RCTs showed no sinificant difference between topical antimicrobial plus corticosteroid combinations and topical corticosteroids alone. The papers described wet wrap treatments by using RCT design did not assess the difference between wet wrap and placebo but between pre and post. Five RCTs showed long term relapse prevention by pulsed application of mometasone furoate, fluticasone propionate or vetamethasone valerate without no serious systemic adverse effects or skin atrophy.
