Tofacitinib Citrate: Janus Kinase (JAK) Inhibitor

Tofacitinib citrate is an oral, small-molecule inhibitor of the Janus kinase (JAK) family, with preferential selectivity for JAK1 and JAK3 over JAK2. By blocking JAK-dependent cytokine signaling through the JAK-STAT pathway, tofacitinib modulates the immune response involved in inflammatory and autoimmune conditions. It was first approved for rheumatoid arthritis and has since expanded into other inflammatory indications.
