Evaluation of cutaneous vasoconstriction after applications of varying duration of topical corticoids on the flexor surfaces of the forearms of 20 patients with intact skin shows a significantly faster blanching effect with diflucortolone valerate ointment than with fluocinolone acetonide and betamethasone valerate ointments. Furthermore, the test shows that even for a highly active preparation, such as the diflucortolone valerate ointment, an application time of less than 3 h only exceptionally leads to vasoconstriction in the healthy skin.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
