A critical review on formulation and evaluation of colon targeted drug delivery systems

A multidisciplinary scientific field that is fast growing nanotechnology, often known as molecularly generated systems and technologies. Nanotechnology a rapidly expanding of applied science engineering. It relies upon the concept nano-scale manipulation matter, meaning ability to handle materials on microscopic scale. Nanoparticles can be used deliver variety substances, including conventional drugs, recombinant proteins, vaccines, more recently nucleotides. other colloidal drug delivery techniques change kinetics, body distribution, release related drug. The treatment negative effects distribution therapy targets certain tissues or cells are additional effects. As result, nanoparticles in pharmaceutical biotechnology industries boost therapeutic index provide solutions impending problems for new classes so-called biotech medicines such proteins oligonucleotides.
