Baricitinib is an orally selective and reversible Janus kinase (JAK1 and JAK2) inhibitor. JAK is an enzyme that initiates the signal transduction pathway and activates haematopoiesis and immune functions. It initiates gene expression within the cell through phosphorylation, stimulation of signal transducers and activation of transcription (STATs). It eventually decreases serum IgG, IgM, IgA, and C-reactive protein.
