A Double-blind Controlled Comparison of Generic and Trade-Name Topical Steroids Using the Vasoconstriction Assay
Elise A. Olsen, MD
Arch Dermatol. 1991;127(2):197-201.
Abstract
Six generic formulations of five topical steroids were compared for bioequivalence with their trade-name counterparts using an in vivo vasoconstriction assay. Two of six generic formulations were found to show significantly less vasoconstriction than the respective trade-name topical steroids. The issue of generic equivalence of topical steroids is discussed, with particular emphasis on the vagaries of the vasoconstriction assay.
