The study demonstrated that venlafaxine exhibits significant anti-arthritic activity by reducing inflammation, improving pathological indicators, and alleviating pain associated with arthritis.
Venlafaxine is a serotonin-norepinephrine reuptake inhibitor used to treat depression. Previous studies demonstrated its anti-nociceptive and anti-inflammatory activities through the suppression of pro-inflammatory cytokines. Present research aimed to explore its anti-arthritic potential. Different in-vitro assays including egg albumin, bovine serum albumin denaturation and human red blood cell (RBC) membrane stabilization assays along with in-vivo models of formaldehyde and complete Freund's adjuvant-induced arthritis were used to study its anti-arthritic effect. Venlafaxine inhibited egg albumin and bovine serum albumin denaturation and preserve the integrity of red blood cells membrane in concentration-dependent manner. In formaldehyde-induced arthritis venlafaxine significantly (p < 0.001) reduced the paw edema on treatment for 10 days. Chronic administration of venlafaxine for 28 days in Freund's adjuvant-induced arthritis model decreased the paw volume (p < 0.001), arthritic index (p < 0.01), flexion pain score (p < 0.05), mobility score (p < 0.05), and improved the stance score (p < 0.05). Venlafaxine also significantly declined the rheumatoid factor (p < 0.01) and C-reactive protein (p < 0.05) levels and increased the RBC count (p < 0.01) and Hb value (p < 0.001). Upon PCR analysis venlafaxine remarkably turndown the mRNA expression of TNF-alpha, IL-6, IL-1 beta, and COX-2. Taken together it is inferred from current findings that venlafaxine possesses the significant anti-arthritic activity and could be a potential therapeutic option for the treatment of rheumatoid arthritis.
