Do tofacitinib tablets contain hormones? What are its ingredients and effects on patients?

Tofacitinib tablets do not contain hormone ingredients. It is a small molecule targeted drug that belongs to the Janus kinase (JAK) inhibitor family, and its main component is tofacitinib itself. Unlike traditional hormonal drugs such as glucocorticoids, tofacitinib does not directly act on the endocrine system in the body, but affects the signaling of a variety of pro-inflammatory cytokines (such as IL-6, IL-2, IFN-γ, etc.) by inhibiting the JAK1 and JAK3 pathways. Through this mechanism, it can effectively regulate immune responses, reduce abnormal inflammatory activity, and has a good therapeutic effect on chronic immune-mediated diseases such as rheumatoid arthritis, psoriatic arthritis, and ulcerative colitis.

Since it does not contain hormones, tofacitinib avoids the common side effects of long-term use of hormone drugs, such as osteoporosis, hyperglycemia, moon face, etc. However, it should be noted that as an immunomodulator, the immunosuppressive effect of tofacitinib may still increase the risk of infections, including herpes zoster, pulmonary infections, and even opportunistic infections. Therefore, during use, doctors usually recommend regular monitoring of blood routine, liver function and lipid levels, and be alert to early signs of infection.

In addition, tofacitinib is also associated with a slight increase in the risk of cardiovascular events and the incidence of malignant tumors, especially in older patients or those with pre-existing medical conditions. Therefore, although tofacitinib is not a hormonal drug, strict medical management is still required during the treatment process, and the risks and benefits of use are reasonably assessed. In the future, as the understanding of JAK inhibitors deepens, the population selection and safety monitoring strategies for tofacitinib will also be continuously optimized to achieve more personalized and precise treatment.
