Simponi 50mg injection contains an active component as Golimumab. It is a monoclonal antibody drug used to treat autoimmune diseases, particularly certain inflammatory conditions. It works by targeting and inhibiting a certain protein, which plays a role in causing inflammation in the body. It is used to treat moderate to severe rheumatoid arthritis in adults, often in combination with other disease-modifying antirheumatic drugs (DMARDs). It is also approved for treating psoriatic arthritis, an autoimmune condition affecting joints and skin. It can treat ankylosing spondylitis, a type of arthritis primarily affecting the spine and sacroiliac joints. One of the advantages of this medication is that it offers relatively long dosing intervals compared to other biological medications.
