IGURATIMOD is used to treat rheumatoid arthritis. Rheumatoid arthritis is an auto-immune disease (the body's immune system attacks its tissue) which leads to joint pain and damage. Rheumatoid arthritis is characterised by loss of joint function, progressive bone destruction, and joint synovitis (inflammation of the joints). IGURATIMOD contains 'Iguratimod', which inhibits the production of immunoglobulins and inflammatory cytokines. It inhibits osteoclast differentiation and bone resorption, thereby stimulates bone metabolism. IGURATIMOD provides relief from pain and inflammation by inhibiting cyclooxygenase-2, an enzyme that is responsible for pain and inflammation.
