A multistage nanodelivery vehicle was developed by loading of budesonide containing poly(lactic-coglycolic acid) (PLGA) nano-particles into silicon nanoporous microparticles. The combination of micro- and nanoparticles utilizes each of the strengths of each component to be employed in oral drug delivery to inflammatory bowel disease (IBD). Drug efficiency was tested in a recently reported by us in vitro model of IBD.
