Tumor necrosis factor inhibitor (TNFi) drugs are a class of drugs that are used worldwide to treat inflammatory conditions such as psoriasis, juvenile arthritis, inflammatory bowel diseases, ankylosing spondylitis and of course, rheumatoid arthritis. These drugs are able to reduce inflammation and stop disease progression.
How does it work?
TNF is the substance in our body that causes inflammation and leads to immune-system diseases. In healthy individuals, excess TNF in the blood is blocked naturally. In those who have rheumatic conditions, high levels of TNF lead to more inflammation and persistent symptoms. This is why TNF inhibitors are used to reduce this inflammation.
