A double-blind comparison of 0.25% and 0.05% desoxymethasone, 0.1% betamethasone valerate and 1% hydrocortisone creams in the treatment of eczema.

The efficacy and acceptability of 0.25% and 0.05% desoxymethasone, 0.1% betamethasone valerate and 1% hydrocortisone creams were compared in patients with eczema. A double-blind parallel group multi-centre design was employed in which 96 patients were recruited by four centres. Patients used one cream for a 3-week period and follow-up assessment visits were made at weekly intervals. Efficacy variables were: erythema/redness, scaling, itching and extent of area affected. These variables were assessed by both the investigator and the patient. The 0.25% desoxymethasone was the most effective treatment, producing the greatest degree of improvement in all clinical parameters, hydrocortisone was the least effective and 0.05% desoxymethasone was of intermediate effectiveness. The 0.1% betamethasone produced similar results to 0.25% desoxymethasone for half the assessments; for the other half the results were similar to 0.05% desoxymethasone. No adverse effects were reported during the study. The results are discussed in terms of physical properties of the vehicles and corticosteroid potency.
