APO-Leflunomide general information
What is APO-Leflunomide used for?
APO-Leflunomide tablets 20mg are used to treat rheumatoid arthritis and active psoriatic arthritis, which are both autoimmune disorders (when the immune system attacks self), have an overactive immune system and have a genetic predisposition. Rheumatoid arthritis is a chronic progressive disease of the joints in which inflammation causes joint destruction and deformity of the joints. APO-Leflunomide 20 can help slow down the process of joint destruction and improve functional ability and quality of life and is particularly helpful in patients who do not respond to other treatments or if other treatments cannot be used. Psoriatic arthritis is a form of arthritis that is often also associated with psoriasis of the skin, characterised by raised red patches covered in silvery scales, but can develop before skin symptoms appear. Psoriatic arthritis differs from rheumatoid arthritis by being negative for rheumatoid factor, a blood test for an antibody that is usually positive in rheumatoid arthritis. APO-Leflunomide tablets 20mg are used only for treating inflammation of the joints in psoriatic arthritis not for the skin condition alone. Rheumatoid arthritis and active psoriatic arthritis are both characterised by periods of remission and periods of flare up when symptoms worsen and joints become painful and swollen. APO-Leflunomide tablets 20mg will not cure arthritic disease but can be used to relieve symptoms of the disease including pain, inflammation, tenderness, stiffness and swelling in the affected joints, and improve the functional use of affected joints.
How does APO-Leflunomide work?
APO-Leflunomide tablets 20mg contain leflunomide, a disease-modifying antirheumatic drug (DMARD) that is used to relieve inflammatory symptoms of the arthritic diseases rheumatoid arthritis and active psoriatic arthritis. Leflunomide in APO-Leflunomide tablets 20mg acts as an immunomodulatory drug with immunosuppressive characteristics, which means that it can suppress the immune system by interacting directly with the lymphocytes (white blood cells) involved in the immune response. Leflunomide in APO-Leflunomide tablets 20mg works by several possible mechanisms. It is thought to inhibit the production by lymphocytes of inflammatory mediators called cytokines, such as interleukins and prostaglandins, particularly tumour necrosis factor (TNF), interleukin 1 (IL1) and interleukin 6 (IL6). Leflunomide in APO-Leflunomide tablets also inhibits proliferation of rapidly dividing inflammatory lymphocytes by blocking the action of dihydroorotate dehydrogenase, an enzyme involved in pyrimidine synthesis, which inhibits lymphocyte proliferation, and helps reduce the inflammation that is responsible for the pain and swelling of rheumatic joints. These actions of leflunomide in APO-Leflunomide tablets 20mg dampen down the immune response by interacting with immune cells that influence the immune response to autoantigens (directed against self) and help reduce progression of the disease and reduce symptoms.
What does APO-Leflunomide contain?
APO-Leflunomide contains the active ingredient leflunomide 20mg, a disease-modifying antirheumatic drug (DMARD) used to treat rheumatoid arthritis and active psoriatic arthritis. They also contain lactose, crospovidone, magnesium stearate, and colloidal silicon dioxide.
Treating rheumatic diseases with APO-Leflunomide
APO-Leflunomide tablets 20mg contain leflunomide, a disease-modifying antirheumatic drug (DMARD) that is used to treat rheumatoid arthritis and active psoriatic arthritis, to improve symptoms of the disease, which include pain, inflammation, tenderness, stiffness and swelling in the affected joints. Rheumatoid arthritis and psoriatic arthritis (a form of arthritis that is often also associated with psoriasis of the skin, causing raised red patches covered in silvery scales) are both autoimmune disorders (when the immune system attacks self) and are characterised by an overactive immune system and a genetic predisposition. Leflunomide in APO-Leflunomide tablets 20mg is an immunomodulatory drug and acts directly on the lymphocytes (white blood cells) involved in the immune response, by inhibiting the production of cytokines, which are inflammatory mediators. Also, Leflunomide in APO-Leflunomide tablets 20mg blocks the proliferation of rapidly dividing inflammatory lymphocytes, which helps reduce the inflammation. APO-Leflunomide 20 can help slow down the process of joint destruction and improve joint function and quality of life, by reducing pain and inflammation but will not cure arthritic disease.
