Controlled Drug Delivery System

Controlled drug delivery refers to the one which delivers the drug at a predetermined rate for locally or systemically for a specified period of time. The factors influencing the release of DDS include physicochemical properties of drug, physiological factors. Controlled DDS include the maintenance of drug levels within a desired range, the need for less administrations, increased patient compliance. Controlled release drug delivery employs drug encapsulating devices from which therapeutic agents may be released at controlled rates for longer periods of time, ranging from days to months.
