A Review Paper on Polymeric Nanoparticles for Drug Delivery

  • Bhupinder Bhyan


The difficulty of some diseases and the inherent toxicity of certain medications have led to a growing interest in designing and optimizing drug delivery systems. As a key tool to improve drug bioavailability or specific delivery at the site of action, polymeric nanoparticles stand out. Polymer flexibility makes them theoretically suitable for meeting the specifications of each complex method of drug delivery. An overview of the state-of-the-art panorama of polymeric nanoparticles as drug delivery systems was conducted in this study, focusing specifically on those applications in which the corresponding disease entails significant morbidity, a significant decrease in patient quality of life or even a high mortality rate. A revision of the use of polymeric nanoparticles for the delivery of ophthalmic drugs, for the diagnosis and treatment of cancer, and for the delivery of nutraceutical has been carried out, including a brief debate on the future prospects of these systems.
