Abstract
A prodrug is generally designed to improve the physical and chemical properties of a parent drug to enable formulation development, improve delivery, and/or achieve targeting. Similarly a prodrug approach can be used to enable development of a controlled release formulation, i.e., to provide a pharmacokinetic profile with sustained plasma levels. In the following discussion the term controlled release (CR) is used to include all prodrug approaches that result in sustained plasma levels over a dosing duration, thus reducing dosing frequency of the parent drug or the active moiety. CR technologies could include osmotic devices, polymeric matrix, implants, and microspheres and suspensions for parenteral depots that result in sustained plasma levels of the drug.
