The multilayered monolithic type transdermal delivery device has been designed and analyzed by a numerical analysis. The device consists of three layered polymer matrices which posess the different diffusion parameters, respectively. The purpose of this study was to design an ideal transdermal drug delivery device which is capable of initial burst and zero order release later on. Numerical modelings were simulated for a dispersed and a dissolved multilayered monolithic system. The results showed that the dispersed multilayered monolithic system could meet the requirements for an ideal transdermal delivery device.
