Tocilizumab

Tocilizumab is a monoclonal antibody used to treat autoimmune diseases like rheumatoid arthritis and giant cell arteritis. It works by blocking interleukin-6 (IL-6), a protein responsible for inflammation in the body. Tocilizumab is also used in severe COVID-19 cases to reduce inflammation and prevent complications. It is available as an injection and should only be administered under medical supervision.

Uses of Tocilizumab

• Treatment of rheumatoid arthritis.
• Used for giant cell arteritis.
• Reduces inflammation in systemic juvenile idiopathic arthritis (sJIA).
• Effective for polyarticular juvenile idiopathic arthritis (pJIA).
• Approved for cytokine release syndrome (CRS) in severe COVID-19 cases.

How Tocilizumab Works

Tocilizumab blocks interleukin-6 (IL-6) receptors, which play a major role in inflammation. By inhibiting IL-6, it reduces swelling, pain, and joint damage in autoimmune conditions. In cytokine storms, it helps control excessive immune responses, preventing organ damage.

Benefits of Tocilizumab

• Effectively reduces joint inflammation and pain.
• Prevents joint damage in rheumatoid arthritis.
• Helps control severe immune reactions in COVID-19.
• Improves mobility and quality of life in arthritis patients.
• Reduces the risk of long-term disability in autoimmune diseases.
