FA P120-122. Immunosuppressants for RA are calcineurin inhibitor (cyclosporine and tacrolimus), 6MP, and TNFa inhibitors (adalimumab,infliximab, etanercept). It is important to distinguish that calcineurin inhibitors block t cell activation by preventing IL-2 transcription, not necessarily block IL-2 action. Sirolimus(rapamycin) blocks IL-2 action but it is used for kidney transplant rejection prophylaxis specifically.
in addition to the above responses, IL 1 antagonists (Anakinra) can be used to treat RA. Anakinra is a recombinant human IL 1 receptor anatagonist but less effective than other treatment modalities.
Prednisone is a glucocorticoid (which inhibits IL-2 synthesis) is already being used with no effect. So TNF-alpha is the next option.
DMARDs: methotrextate, sulfasalazine, hydroxychloroquine, leflunomide, TNF inhibitors, Anti- IL6 (Tocilizumab), JAK inhibitor (Tofacitinib), Rituximab.
You can use cyclosporine and tacrolimus to treat RA, but those aren't first line treatments. DMARDs are used the long term treatment of RA and methotrexate is often started first, and the other drugs are prescribed if methotrexate does not sufficiently control symptoms. None of the other choices listed are a part of DMARD therapy.
Thank you so much @avocadotoast precisely what I was thinking. I don’t think we have to think beyond the basic dmards step 1

Im also convinced blocking IL-2 is also a treatment? WHy is TNF-alpha the better answer here?
