    The drug delivery from a diffusion based delivery system can be simulated using the transport of diluted species module in Comsol Multiphysics™. In order to predict how fast the drug diffuses from the active layer to a dissolution vessel or a physiological body, the compartments of the drug delivery system have to be defined in Comsol ...

    https://link.springer.com/chapter/10.1007%2F978-1-4614-0881-9_6
    Sep 27, 2011 · Abstract. This chapter presents an overview on the different types of drug delivery systems that are predominantly governed by diffusion. The systems are classified according to their physical structure (reservoir devices versus monolithic systems), as well as according to the ratio of “initial drug loading and drug solubility.”Author: Juergen Siepmann, Ronald A. Siegel, Florence Siepmann
