Title: Polymer matrix supported drug delivery system: designing controlled-release formulations involving concept of nano-technology
Biography: Nobuhito Shibata
Main purposes of drug delivery system (DDS) are improvement of drug absorption, controlled-release of drug and passive and/or active tissue targeting to maintain optimal drug levels in tissues. So called, all these concepts are for the sake of optimization of drug therapy. In regard to the controlled-release system, a large number of studies about it elsewhere in literatures, and numerous formulations have been provided by pharmaceutical industries on the market. On the other hand, progress in nano-technology has developed several ways to construct nano-device for DDS, and has enabled us to prepare DDS formulations which have more intelligent functions such as cancer or gene targeting. Nevertheless, as pharmaceutical additives, polymers which are derived from natural or artificial sources have important roles for designing DDS based on the nano-concept. In this keynote lecture, I’ll introduce my researches about construction of polymer matrix supported DDS, which are controlled-release systems, based on the nano-concept.
