Mathematical modeling and computer simulations can be very effective in improving and optimizing the performance of the self-regulating release of therapeutic drugs into specific regions of the body.  development of a reliable computational design tool for predicting the resulting pharmacokinetic dose distributions as a function of time and space.  Of primary importance in such models are the time-varying effective permeability of the capsule to the various molecules composing the drug, the effective solubility and diffusion coefficients of the drug and its metabolites in the surrounding tissues and fluids and the uptake of the drug at the target organ.
