Dose-dependent effect of topical corticosteroids on blood flow in human cutaneous tissue.

In seven healthy subjects the dorsum of the hand was treated with beta-methasone valerate cream in increasing concentrations, from 0.1 to 1.0%, and with hydrocortisone butyrate 0.1% with or without plastic occlusion. Under conditions of controlled room temperature, blood flow in treated, placebo-treated, and untreated cutaneous tissue was measured using the local 133Xenon wash-out technique. Placebo creams did not affect cutaneous blood flow, but beta-methasone valerate 0.1% reduced blood flow and 1.0% increased it. An increase in blood flow was also observed after use of hydrocortisone butyrate under plastic occlusion. The results indicate a dual effect of potent corticosteroids on cutaneous blood flow.
