Controlled drug delivery technology represents one of the most rapidly advancing areas of pharmaceutical science. The applications of controlled drug delivery applications include both sustained (over days/weeks/moths/years) delivery and targeted (e.g. to a tumor, diseased and blood vessel) delivery on a one-time or sustained basis. Polymer-based drug delivery systems are used to optimize the therapeutic properties of drugs and render them safer, effective and reliable. Such delivery systems offer numerous advantages compared to conventional dosages forms which include improved efficacy,...
