What diseases does Upatinib/Ruifu Tablets mainly treat and who is it suitable for?

Upadacitinib (Upadacitinib) is an oral small molecule Janus kinase (JAK) inhibitor. In recent years, it has been used in many countries and regions around the world to treat a variety of immune-mediated inflammatory diseases. Judging from overseas guidelines and real-world drug use experience, the application field of upadatinib is no longer limited to a single rheumatic disease, but has gradually expanded to multiple directions such as joints, skin, digestive system, and vasculitis, reflecting its broad potential in immune regulation.

1. In the field of rheumatism and immunity, upadatinib was first used for patients with rheumatoid arthritis (RA), especially for people who have poor response to traditional disease-improving anti-rheumatic drugs or who are not suitable for long-term use of biological agents. Its oral administration provides a more convenient option for adult patients requiring long-term treatment. On this basis, upadatinib is also gradually being used in patients with active psoriatic arthritis (PsA) as well as ankylosing spondylitis and axial spondyloarthritis. These diseases are usually accompanied by chronic pain, limited joint mobility and reduced quality of life, and have a high demand for continuous and stable immune regulation treatment.

2. In the field of dermatology, atopic dermatitis (AD) is one of the more prominent indications for the application of upadatinib. For patients with moderate to severe atopic dermatitis, especially those who are not well controlled by topical medications or traditional systemic treatments, oral JAK inhibitors have received more attention in terms of alleviating itching and improving skin lesions. In overseas clinical practice, upadatinib is often used in adult patients and some eligible adolescent patients, but the specific use of the drug still requires strict evaluation of infection risks and long-term safety.

3. In terms of digestive system diseases, the indications of upadacitinib have been extended to ulcerative colitis (UC) and Crohn's disease (CD). Patients with this type of inflammatory bowel disease often have a protracted course and high relapse rate, and some patients do not respond adequately to traditional immunosuppressants or biological agents. Upadatinib provides a new oral treatment idea for patients with moderate to severe active disease by regulating inflammatory signaling pathways, and has gradually been included in discussions on treatment strategies overseas.

4. With the deepening of research, the application of upadatinib in diseases such as giant cell arteritis (GCA) and active polyarticular juvenile idiopathic arthritis (pJIA) has also attracted attention. These diseases mostly involve systemic inflammatory reactions and have high requirements for precise immune regulation. For some children and adolescent patients, whether to use upadacitinib needs to be carefully evaluated by a specialist, focusing on growth and development, infection risks and long-term medication safety.

Overall, the applicable population of upadatinib mainly includes patients with moderate to severe immune-inflammatory diseases, especially adult patients who have poor response to traditional treatment options, poor compliance with injection treatment, or who wish to use oral targeted drugs. As overseas application experience continues to accumulate, its scope of indications and population definition are still being continuously optimized.
