Introduction Polymers are used extensively in our daily routine life. • Use of polymer science with Pharmaceutical sciences led to increase thinking in novelty in design and development of NDDS. The basic concepts of polymer chemistry, polymer properties, types of polymers, polymers in pharmaceutical and biomedical industries, and reviews of some polymeric products in novel drug delivery systems and technologies will be covered. Diffusion based drug delivery systems (as shown in Figure 1) and solvent activated drug deliv-ery systems are the other areas being explored for utilizing the polymers [1]. 2. 1 0 obj
