Mathematical modeling of drug release can be very help ful to speed up product development and to better understand the mechanisms of drug release from advanced drug delivery systems. The aim of this article is to obtain an exact solution for the release kinetics of reservoir delivery devices with spherical and cylindrical shapes to the body, (from an in finite source of drug to an infinite sink), with boundary layers considered in both sides of membrane. Devices with

diffusion, cylinder, sphere, infinite, drug delivery
