Reproducibility of clinical trials of topical glucocorticosteroids.

Clinical trials of topical glucocorticosteroids employ a variety of evaluating methods. This makes it difficult to assess the relative strengths of the products without resorting to direct comparative trials between them. We propose a standardized evaluation system for this class of pharmaceuticals that can easily be adopted by any competent dermatologist. Its use would facilitate evaluation of new topical glucocorticosteroids.
