How does Xeljanz (tofacitinib) work?
The active substance in Xeljanz, tofacitinib, acts on enzymes known as Janus kinases. These enzymes play an important role in the process of inflammation4 that characterises inflammatory diseases such as rheumatoid arthritis, psoriatic arthritis and ulcerative colitis. By blocking their action, tofacitinib helps reduce the inflammation and other symptoms of inflammatory diseases4.
