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} } 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. pH sensitive systems: Controlled drug delivery systems, which are intended to deliver drugs at predetermined rates for predefined periods of time, have been used to overcome the shortcomings of conventional drug formulations. Use of polymer … Corpus ID: 8566769. Advances in polymer science have led to the development of several novel drug delivery systems. Oct 24, 2020 polymers for controlled drug delivery Posted By Paulo CoelhoPublishing TEXT ID a379a3ec Online PDF Ebook Epub Library Bioresorbable Polymers For Controlled Active Delivery bioresorbable polymers for controlled active delivery developers of long acting implantables lai now have another option for achieving zero order release kinetics of hydrophilic and hydrophobic drugs other Polymer plays a vital role in novel drug delivery systems with its longevity and self-transforming quality as excipient in tablet and capsule formulations. 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 . 4. 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]. OF PHARMACEUTICS Factors & Types 2. Novel drug delivery systems include micelles, dendrimers, lipo-somes, polymeric nanoparticles, cell ghosts, microcapsules and lipoproteins. 01 CONTROLLED RELEASE DDS Project date 20/09/2013 Al Ameen College of Pharmacy BY: SURAJ CHOUDHARY M.PHARM (PHARMACEUTICS) DEPT. A transdermal drug delivery system (TDDS) is thus a formulation or device (for example, a transdermal patch) that maintains the blood concentration of the drug within the therapeutic window ensuring that drug levels neither fall below the minimum effective concentration nor exceed the minimum toxic dose (Kalia and Guy 2001).

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. 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. A proper Extensive applications of polymers in drug delivery have been realized because polymers offer unique properties which have not been attained by any other materials. 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.
