Rheumatoid arthritis (RA) is a chronic inflammatory illness caused by an autoimmune disorder of synovial membrane resulting in synovial membrane dysfunction. The available treatment particularly focuses on inhibiting macrophage proliferation and reducing the generation of pro-inflammatory cytokines. However, therapeutic success of current treatment options at targeted site is limited; therefore, development of promising therapeutic strategy is the need of time that may provide better targeted delivery of drug with added safety. In development of precision medicine to manage RA, nanotechnology is a viable option to be considered. Recent research using nanoparticles for the treatment of RA, particularly polymeric nanoparticles, has been discussed in this article. Using polymeric nanoparticles as a therapeutic method has shown considerable promise of enhancing treatment success over standard medications used in routine. It is exclusively evident that the viability of using nanoparticles is mainly owed due to their biocompatibility, chemical stability, controlled drug release, and selective drug delivery to inflamed tissues in RA model animals. The current analysis focuses on the critical design characteristics of RA-targeted nanotechnology-based strategies in quest of better therapeutic strategies for RA, and to identify leading polymer as the most effective medications in RA therapy.

Rheumatoid arthritis is an inflammatory arthropathy, autoimmune in nature, leading to disability of joints involving structural destruction of articular bone and cartilage due to inflammation in synovium resulting in joint stiffness, swelling and pain. Nanomedicine has played a crucial role in improving the efficacy of treatment by controlling the release of pharmacologically active ingredients to increase bioavailability and achieve uniform and targeted delivery of drug. In this study, we prepared celecoxib, gingerol and oleanic acid loaded PLGA nanoparticles by solvent evaporation method and nanoparticles were characterized by particle size, zeta potential, polydispersity index, entrapement efficiency and FTIR. FCA is induced in right hand paw of rats for induction of arthritis. Celecoxib, gingerol and oleanic acid loaded PLGA nanoparticles coated with chitosan were given orally to rats for the evaluation of anti-arthritic effect of this nanoformulation in rats. Animals were divided into six groups for 21 days trial. On 21st day blood samples were collected for evaluation of hematological and lipid profile parameters. The data was subjected to statistical analysis by applying one way ANOVA and tukey test. At the end of study it was concluded that PLGA loaded celecoxib, gingerol and oleanic acid coated with chitosan have excellent effects in minimizing the side effects and increasing the therapeutic efficacy of drugs.
