Tofacitinib citrate is an oral drug used for treating rheumatoid arthritis. It belongs to a class of drugs called Janus kinase (JAK) inhibitors. JAKs are enzymes (proteins) that regulate chemical signaling pathways that control biologic processes such as blood formation and the immune response that causes the pain, tenderness and swelling of inflammation. JAKs are found in many cells, especially stem cells in bones and joints. Inhibition of JAKs by tofacitinib prevents inflammation and tissue destruction that is associated with the inflammation of rheumatoid arthritis.

Function:

(1).Tofacitinib citrate is an oral, small molecule drug used to treat adults with moderate-to-severe, active rheumatoid arthritis who have not responded well to being treated with methotrexate. Methotrexate is a disease-modifying antirheumatic drug (DMARD) used to treat rheumatoid arthritis (RA).
(2).Tofacitinib acts to block the body's production of enzymes called Janus kinases (JAKs). JAKs play a role in joint inflammation in RA, which can cause pain, swelling and stiffness. If left untreated, RA inflammation could lead to joint erosions, and organ and tissue damage. It may be used alone or in combination with methotrexate or other DMARDs.
