Polymers in Controlled Drug Delivery Systems @inproceedings{Shaik2012PolymersIC, title={Polymers in Controlled Drug Delivery Systems}, author={Mahammad Rafi Shaik and Madhuri Korsapati and Dinakar Panati}, year={2012} } Extensive applications of polymers in drug delivery have been realized because polymers offer unique properties which have not been attained by any other materials.

Contents of the powerpoint on Polymers – Controlled Drug Delivery Systems include: Describe diffusion controlled devices, using polymers Explain the chemically controlled devices and bioerodible polymer Describe the release mechanisms in terms of hydrophilic and hydrophobic polymer. Therapeutic efficacy and safety of drugs, administrated by conventional methods, can be improved by more precise spatial and temporal placement within the body, thereby reducing both the size and number of doses by using controlled drug delivery system. Nanomedicine and nano delivery systems are a relatively new but rapidly developing science where materials in the nanoscale range are employed to serve as means of diagnostic tools or to deliver therapeutic agents to specific targeted sites in a controlled manner. Novel drug delivery systems include micelles, dendrimers, lipo-somes, polymeric nanoparticles, cell ghosts, microcapsules and lipoproteins. Polymers in Novel Drug Delivery Systems Chemical engineers, pharmacologists and scientists are using polymers for developing controlled drug release systems and sustained release formulations [3]. The study of nanostructured drug delivery systems allows the development of novel platforms for the efficient transport and controlled release of drug molecules in the harsh microenvironment of diseased tissues of living systems, thus offering a wide range of functional nanoplatforms for smart application in biotechnology and nanomedicine. Controlled Release Drug Delivery Systems - Types, Methods and Applications 1. Rationale of controlled drug delivery • The basic idea behind controlled drug delivery concept is to alter the pharmacokinetics and pharmacodynamics of bioactives either by modifying the molecular structure ,and • or physiological parameters by an alternative route of administration or by using novel drug delivery systems .
