Jaktor XR 11 mg Tablet is an extended-release medication containing Tofacitinib, a Janus kinase (JAK) inhibitor. It is primarily used to treat moderate to severe rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, and ulcerative colitis in adults who have not responded well to other treatments. By inhibiting JAK enzymes, Jaktor XR helps to control inflammation and regulate immune system function, which reduces symptoms such as joint pain, swelling, and stiffness, improving overall physical function and quality of life for patients.
