Abstract:A new approach for improving the availability of topically applied drugs by reducing the permeability of dermis has been evaluated. The premise of this work is that photothermal vascular injury will reduce vascular uptake of drug in the dermis. The dermal distribution of two topically applied drugs, 5-fluorouracil and mitomycin C, is calculated, considering molecular diffusion and vascular uptake according to a distributed model, in the presence and absence of vascular injury. Intradermal drug exposures obtain… Show more
