Abstract

Drug delivery systems (DDSs) are designed to be able to precisely control the release rate and/or target drugs to specific body sites. However, the successful application of DDSs could be limited in the clinical application due to the complicated environment of the human body. This can be exampled by the short circulation time and low targeting efficiency of target-specific DDSs induced by the RES recognition, or low bioavailability of drugs caused by short residence time of transmucosal DDSs at the site of absorption. Regarding this, in this chapter, strategies to improve the performance and bioavailability of starch-based DDSs are discussed. Target-specific starch-based DDSs can be achieved by passive and active targeting. Another possible strategy is the physical targeting of drugs by external stimuli, such as magnetic field. Also, the role of starch and its derivatives in transmucosal DDSs to improve the bioavailability of drugs by interacting with the absorbing mucosa or prolonging the residence time of drugs in the absorbing tissues are highlighted.
