BIOEQUIVALENCE OF TOPICAL DRUGS: USE OF THE CADAVER SKIN MODEL Thomas J. Franz M.D. Dermtech International San Diego, CA 92128
CADAVER SKIN MODEL • Widely used to optimize topical formulations, maximize BA • Able to measure rate and extent of drug absorption through skin • 40-year experience with the model • Good in-vitro to in-vivo correlation
COMPARISON OF CLINICAL AND CADAVER SKIN DATA • Validation of cadaver skin model requires comparison to clinical data, the current gold standard • Generic formulations of tretinoin gel 0.01% and 0.025% (Spear Pharm.) shown to be BE to Retin-A Gel 0.01% and 0.025% following clinical testing. • Will the cadaver skin model reach the same conclusion?
