Mode 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...

If a serious infection develops, interrupt Tofacitinib until the infection is controlled. Lymphomas and other malignancies have been reported in patients treated with Tofacitinib Gastrointestinal Perforations – Use with caution in patients that may be at increased risk.
