Mathematical Model of Drug Release From Porous Polymer

Li Yanli 1 Cheng Guoli 2 Li Lingbing 3 1(Jinan Fourth Hospital,Jinan 250031) 2(Attached Hospital of Shandong University,Jinan 250100) 3(Department of Pharmaceutics,Shandong University,Jinan 250012)  
A mathematical model describing the drug release from porous polymer was established by using the species continuity equation.The relative permeating rate was introduced to describe the effects of the different physical processes. An asymptotic solution has been obtained by using the perturbation theory.The whole process of the drug release from porous polymer was analysized,especially the process controlled by drug dissolution.
