Basically, TNF-alpha acts like a messenger that summons the immune cells of inflammation to participate in the inflammation. By blocking the action of TNF-alpha, Remicade reduces the inflammation and its accompanying signs and symptoms. Remicade does not cure rheumatoid arthritis. However, studies have demonstrated that Remicade can inhibit the progress of joint destruction from rheumatoid arthritis. Remicade can either be used alone or is often combined with methotrexate for treating rheumatoid arthritis in patients who have not adequately responded to methotrexate alone. In these patients, the drug is used to prevent joint damage that is caused by the rheumatoid arthritis.
Rheumatoid arthritis is a chronic joint disease that damages the joints of the body. The damage is caused by inflammation of the joint lining tissue. Inflammation is normally a response by the body's immune system to "assaults" such as infections, wounds, and foreign objects. In rheumatoid arthritis, the inflammation is misdirected to attack the joints. Rheumatoid arthritis is often referred to as RA. The inflammation in the joints causes pain, stiffness, and swelling, as well as many other symptoms. The inflammation often affects other organs and systems of the body.
