Topical glucocorticosteroids are frequently used for the treatment of sunburn despite the scarcity of randomized, double-blind controlled trials to support this indication. This randomized, intra-individually controlled trial compared the efficacy and safety of two topical glucocorticosteroids, 0.1% methylprednisolone aceponate milk (MPA) and 0.1% hydrocortisone 17-butyrate emulsion (HCB), for treatment of sunburn in 24 healthy volunteers of skin type III. After irradiation of the skin by simulated sunlight, treatments were blinded and randomly allocated to 36 cm2 test areas on both sides of the spine. Volunteers were treated twice daily for 7 days and assessed daily with 1-day follow-up. The untreated area was not blinded. Primary efficacy measures were sum score and sunburn reaction based on erythema, oedema, burning and itching. Secondary efficacy measures were physician's global assessment, individual signs/symptoms, colorimetry, dermatological improvement, and time to healing. Intra-individual comparisons were made. Differences in sum score were apparent on days 3-4 and significant on days 4-5 for corticosteroids compared with nontreatment. Treated areas had significantly lower sunburn reaction than untreated areas (P = 0.1% and P = 0.5% for MPA and HCB, respectively). Differences between treatments were not significant. Secondary efficacy measures were in line with these findings. None of the three adverse events reported were considered to be related to treatment. We conclude that MPA and HCB are safe and effective in the treatment of sunburn.
