Controlled drag delivery systems received considerable attention in the last years and they are providing in general a more controlled rate of uptake of the drag by the body. In this way their therapeutic action is prolonged without increasing the dosage. The common way of controlling the release is by incorporating the drug in a polymeric carrier: the active pharmaceutical is released in the affected site by way of diffusion or surface erosion.
