RESUMEN
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.
