GENERIC NAME: adalimumab

BRAND NAME: Humira

DRUG CLASS AND MECHANISM: Adalimumab is an injectable protein(antibody) that blocks the inflammatory effects of tumor necrosis factor alpha (TNF alpha) in rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, and Crohn 's disease of the intestine. Inflammation is the body's reaction to injury and is a necessary process for the repair of injury. TNF is a protein that the body produces when there is inflammation. TNF promotes inflammation and the signs of inflammation, which, in the case of arthritis, include fever as well as pain, tenderness, and swelling of joints. In the case of Crohn's disease, the signs of inflammation include fever, abdominal pain, and diarrhea. The unchecked inflammation of rheumatoid arthritis eventually leads to destruction of the joints. The inflammation in Crohn's disease can lead to strictures (narrowing) of the intestine or intestinal perforation. Adalimumab is a synthetic (man-made) antibody that binds to TNF in the body and thereby blocks the effects of TNF. As a result, inflammation and its consequences in the joints and intestine are reduced. In arthritis, the progressive destruction of the joints is slowed or prevented. Adalimumab is a disease modifying anti-rheumatic drugs (DMARD) because it slows or prevents destruction of joints. Adalimumab was approved by the FDA in December 2002.
