Both are JAK inhibitors. Here is how Rinvoq and Jakafi compare on class, mechanism, dosing, approval and supply.
RINVOQ/RINVOQ LQ is a Janus kinase (JAK) inhibitor. RINVOQ is indicated for the treatment of adults with moderately to severely active rheumatoid arthritis who have had an inadequate response or intolerance to one or more TNF blockers. ( 1.1 ) Limitations of Use RINVOQ is not recommended for use in combination with other JAK inhibitors, biologic DMARDs, or with potent immunosuppressants such as azathioprine and cyclosporine. ( 1.1 ) RINVOQ/RINVOQ LQ is indicated for the treatment of adults and pediatric patients 2 years of age and older with active psoriatic arthritis who have had an inadequate response or intolerance to one or more TNF blockers. ( 1.2 ) Limitation s of Use RINVOQ/RINVOQ LQ is not recommended for use in combination with other JAK inhibitors, biologic DMARDs, or with potent immunosuppressants such as azathioprine and cyclosporine. ( 1.2 ) RINVOQ is indicated for the trea…
JAKAFI/JAKAFI XR is a kinase inhibitor indicated for treatment of: intermediate or high-risk myelofibrosis, including primary myelofibrosis, post-polycythemia vera myelofibrosis, and post-essential thrombocythemia myelofibrosis in adults. ( 1.1 ) polycythemia vera in adults who have had an inadequate response to or are intolerant of hydroxyurea. ( 1.2 ) steroid-refractory acute graft-versus-host disease in adult and pediatric patients 12 years and older. ( 1.3 ) chronic graft-versus-host disease after failure of one or two lines of systemic therapy in adult and pediatric patients 12 years and older. ( 1.4 ) 1.1 Myelofibrosis JAKAFI/JAKAFI XR is indicated for treatment of intermediate or high-risk myelofibrosis (MF), including primary MF, post-polycythemia vera MF, and post-essential thrombocythemia MF in adults. 1.2 Polycythemia Vera JAKAFI/JAKAFI XR is indicated for treatment of polycy…
12.1 Mechanism of Action Upadacitinib is a Janus kinase (JAK) inhibitor. JAKs are intracellular enzymes which transmit signals arising from cytokine or growth factor-receptor interactions on the cellular membrane to influence cellular processes of hematopoiesis 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. Upadacitinib modulates the signaling pathway at the point of JAKs, preventing the phosphorylation and activation of STATs. JAK enzymes transmit cytokine signaling through their pairing (e.g., JAK1/JAK2, JAK1/JAK3, JAK1/TYK2, …
12.1 Mechanism of Action Ruxolitinib, a kinase inhibitor, inhibits Janus Associated Kinases (JAKs), JAK1 and JAK2, which mediate the signaling of a number of cytokines and growth factors that are important for hematopoiesis and immune function. JAK signaling involves recruitment of STATs (signal transducers and activators of transcription) to cytokine receptors, activation, and subsequent localization of STATs to the nucleus leading to modulation of gene expression. MF and PV are myeloproliferative neoplasms (MPNs) known to be associated with dysregulated JAK1 and JAK2 signaling. In a mouse model of JAK2V617F-positive MPN, oral administration of ruxolitinib prevented splenomegaly, preferent…
Which medicine is right for a given person depends on their diagnosis, other conditions, other medicines, kidney and liver function, pregnancy, and cost or reimbursement — none of which this page knows. Two drugs in the same class are not automatically interchangeable. Never start, stop or switch a prescription medicine on the basis of a web page; that decision belongs to you and your clinician or pharmacist.
Class and summary text is written by the Priya Life Science editorial team. Label, mechanism, route, manufacturer and approval data come from the U.S. FDA via the openFDA API; shortage status from the FDA Drug Shortage Database. Approvals, indications and brand names differ between the US, EU/Ireland (EMA/HPRA) and other regions — a drug approved in one may not be approved, or may carry a different name, in another.
