FDA Approves Immunex's Enbrel
Enbrel works by decreasing a certain protein produced by the immune system.
The immune system helps the body fight infections. In people with autoimmune disorders, the immune system mistakes the body's own cells for invaders and attacks them.
Enbrel is used to treat the symptoms of rheumatoid arthritis, psoriatic arthritis, or ankylosing spondylitis, and to prevent joint damage caused by these conditions. Enbrel is also used to treat plaque psoriasis in adults and polyarticular juvenile idiopathic arthritis in children who are at least 2 years old.
ENBREL is a prescription medicine that can be self-injected. It is used to treat five lifelong inflammatory diseases: moderate to severe rheumatoid arthritis (RA), moderate to severe plaque psoriasis, psoriatic arthritis, moderate to severe juvenile idiopathic arthritis (JIA), and ankylosing spondylitis (AS).
This medication is used alone or in combination with an immunosuppressant (e.g., methotrexate) to treat certain types of arthritis (e.g., rheumatoid, psoriatic, and ankylosing spondylitis), as well as a skin condition called psoriasis. These conditions are caused by an overactive immune system (autoimmune disease). The immune system attacks the body's own healthy cells, causing inflammation in the joints and skin.
Etanercept controls your body's defensive response by blocking the action of a certain natural substance (TNF) that is used by the immune system. Treatment decreases redness, itching and scaly patches in psoriasis as well as the pain, swelling and stiffness of joints in arthritis. This medication can stop the progression of disease and joint damage, resulting in improved daily functioning and quality of life.
This medication treats but does not cure autoimmune diseases. Symptoms usually return within 1 month of stopping the medication.
Enbrel is used to relieve the symptoms and slow the progress of moderate to severe rheumatoid arthritis. It's also prescribed to relieve the symptoms of psoriatic arthritis. It can be added to methotrexate therapy when methotrexate fails to provide adequate relief. Prescribed alone, it is also used for juvenile rheumatoid arthritis when other drugs have failed.
Enbrel is the first in a class of drugs designed to block the action of tumor necrosis factor (TNF), a naturally occurring protein responsible for much of the joint inflammation that plagues the victims of rheumatoid arthritis. In clinical trials, Enbrel provided the majority of patients with significant relief.
