B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Janus kinases (JAKs) pathways inhibitor; JAK consists of a group of intracellular tyrosine kinases that transmit signals from cytokine or growth factor-receptor interactions on the cellular membrane to influence cellular processes of hematopoieses and immune cell function
Within the signaling pathway, JAKs phosphorylate and activate signal transducers and activators of transcription (STATs) which modulate intracellular activity including gene expression; tofacitinib modulates the signaling pathway at the point of JAKs, preventing the phosphorylation and activation of STATs
These signals are essential in maintaining the inflammatory condition in rheumatoid arthritis (RA); inhibition of JAKs reduces production of and modulates proinflammatory cytokines central to RA

TOFACITINIB EXTENDED-RELEASE - ORAL
(TOE-fa-SYE-ti-nib)
COMMON BRAND NAME(S): Xeljanz XR
WARNING: Tofacitinib may lower your ability to fight infections. This may make you more likely to get a serious (rarely fatal) infection or make any infection you have worse. The most common serious infections include pneumonia, skin infections, shingles, a certain bowel disease (diverticulitis), swelling of the appendix (appendicitis), and urinary tract infections. The risk for infections may be higher if you also take other drugs that suppress the immune system (such as cyclosporine, tacrolimus). Tell your doctor right away if you have any signs of infection (such as a sore throat that doesn't go away, fever, chills, cough, trouble breathing, painful/frequent urination, non-healing skin sores).You should have a tuberculosis (TB) skin test before and during treatment with this medication. Tell your doctor if you have been near someone with tuberculosis or have lived or traveled in areas where certain fungal infections (such as coccidioidomycosis, histoplasmosis) are common. These areas include the Ohio and Mississippi River valleys and the southwestern United States.Though it is very unlikely to occur, there may be a risk of developing cancer (such as lymphoma, skin cancer) with this medication. Tell your doctor right away if you develop symptoms such as fever that doesn't go away, unusual lumps/growths, unexplained weight loss, night sweats, change in appearance or size of moles, or unusual skin changes.Tofacitinib may cause serious (possibly fatal) side effects, including heart problems and blood clots. These side effects occurred more often in patients who were taking higher doses of tofacitinib, who were 50 years of age or older, and who had at least one risk factor for heart disease (such as high blood pressure, diabetes, previous blood clots, high cholesterol). Do not increase your dose or use this drug more often or for longer than prescribed. Discuss the risks and benefits of treatment with your doctor. Get medical help right away if you have symptoms such as chest pain, trouble breathing, pain/swelling/redness of arms or legs, weakness on one side of the body, confusion, or sudden vision changes.People with a kidney transplant who are also taking other drugs that suppress the immune system may be at greater risk for developing a certain white blood cell disorder (Epstein Barr Virus-associated post-transplant lymphoproliferative disorder) with this medication. Discuss the risks and benefits of treatment with your doctor.
