Comparison of individual and combination treatments with naproxen, prednisolone and hydroxychloroquine to treat Complete Freund ’s Adjuvant induced arthritis

AbstractAim of this study was to evaluate and compare the efficacy of anti-arthritic drugs (naproxen, prednisolone, and hydroxychloroquine) alone and in combination. The in vitro anti-arthritic activity was evaluated by stabilization of human erythrocytes (HRBCs) membrane assays. In vivo activity was carried out using Complete Freund ’s Adjuvant (CFA) induced arthritic model in Wistar rat. Individual and combination drugs were administered for 21 days in rats 8 days post inoculation with CFA (0.15 ml injected in right hind paw). Body weight and paw edema were measured at different intervals. Combination treatments exhibited more HRBC stabilization than individual treatments. All individual and combination treatments reduced the level of C-reactive protein (CRP), liver function enzymes, malondialdehyde, white blood cells and platelets, with the most pronounced activity exhibited by the combination of three drugs. The l evel of oxidative stress biomarkers (reduced glutathione, catalase, and superoxide dismutase), red blood cells, and hemoglobin were notably increased in all treatment groups in contrasts to diseased control rats. Histopathological evaluation of the paw showed that all the treatments had reduced (p <  0.05–0.001) the arthritic indices in contrasts to diseased control rats. The serum concentrations of TNF-α and PGE2 were provoked in diseased control rats but had been notably (p <  0.0001) restored by treatments with individual and combination...
