Dermal Physiologically-based Pharmacokinetic (PBPK) Models Accounting for the Absorption and Evaporation of Vehicle/Co-solvent following the Application of Generic Dermatological Products (U01)

The overall objective of this funding opportunity is to develop an enhanced mechanistic PBPK model for generic dermatological drug products by taking account the absorption and evaporation of vehicle/co-solvent simultaneously and implementing the effect of these two dynamic processes on the permeation of drug molecule through skin. The developed model will be utilized to inform decisions on generic dermatological product development, to enhance the understanding of the effect of metamorphosis of dermatological drug products on skin absorption, and to predict the local and systemic exposure of drug molecule following topical application of dermatological drug products.
