- Description: The human skin blanching assay was used to determine the blanching activities of Dermovate, Betnovate and Eumovate creams and ointments. Dermovate was found to elicit a superior blanching response to Betnovate which in turn elicited a superior blanching response to Eumovate, except in the comparison of Betnovate and Eumovate ointments under occlusion. The importance of employing the correct methodology of the blanching assay is emphasized and the good correlation between the results of this study and clinical trials is indicated.

- Description: Six different vehicles for topical use were used to prepare 50% dilutions of Betnovate@ (betamethasone 17-valerate, 0.1 %) cream. Blanching assessment was undertaken immediately after preparing the various dilutions and at 1 and 3 months thereafter. Few statistically significant differences were noted between any of the preparations tested indicating that the rate of release of betamethasone 17-valerate is relatively unaffected by dilution. All preparations were assayed by a stability indicating high pressure liquid chromatographic technique for corticosteroid content. A diminution in the content of betamethasone 17-valerate in the E45 dilution was found 14 months after preparation. All other formulations tested were found to comply with label claim specifications.

- Description: The effect of concentration and occlusion time on the ability of Betnovate ® cream (betamethasone 17-valerate 0.1%) to produce skin blanching was assessed. Generally, increased concentration or occlusion time produce and increase in the degree of blanching observed, however, a plateau stage is eventually reached where no further increase of blanching occurs.
