Overview on Polymeric Drug Delivery Systems
Research in the area of controlled drug delivery systems has gaining increasing interests in the last decades due to the advantages in terms of safety, efficacy (being located in situ) and patient convenience avoiding risks due to surgery. In addition many new-discovered drugs made of peptides are very difficult to administer and drug delivery devices seem to overcome these problems. In general drug delivery devices exist in many forms and can be administered orally, through injection or implantation or transdermally. In this chapter we will focus our attention on the materials used for producing these devices, route of administration and finally on two of the most promising polymer-based drug carrier studied by many research groups all around the world: hydrogels and nanoparticles.
