Immuno Drugs Flashcards
Cyclosporine: Mechanism
Calcineurin inhibitor
- binds to cyclophillins
- complex blocks differentiation and activation of T cells by inhibiting calcineurin thus NO IL-2 and IL-2 receptor production
Cyclosporine: Use
Suppresses organ rejection after transplantation; selected autoimmune disorders
Cyclosporine: Toxicity
Nephrotoxicity, Hypertension, Hyperlipidemia, Hyperglycemia, Tremor, Gingival hyperplasia
Tacrolimus
- Calcineurin inhibitor, binds to FK- binding protein
- inhibits secretion of IL-2
- potent immunosuppressive and used in organ transplant recipients
Tacrolimus Toxicity
HYPERlipidemia, HYPERglycemia, Tremor, HTN, Nephrotoxicity
Sirolimus (Rapamyocin)
inhibits mTOR. Inhibits T-cell proliferation in response to IL-2
- immunosuppression after kidney transplant in combo with cyclosporine and corticosteroids
- used with drug-eluting stents
Sirolimus: Toxicity
Hyperlipidemia, Thrombocytopenia, Leukopenia
Azathioprine
antimetabolite precursor of 6-MP that interfers with metabolism and synthesis of nucleic acids. Toxic to proliferating lymphocytes
- used for kidney transplants, autoimmune disorders (glomerulonephritis and hemoluytic anemia)
Azathiprine Toxicity
Bone marrow suppression. Active metabolite mercaptopurine can be metabolized by xanthine oxidase.
Toxic effects may be increased by allopurinol
Muromonab-CD3 (OKT3)
- monoclonal antibody that binds to CD3 on surface of T cells. Blocks interaction with CD3 protein responsible for T-cell signal transduction
- immunosuppression after kidney transplant
Muromonab-CD3 (OKT3) Toxicity
Cytokine release syndrome
Hypersensitivity reaction
Aldesleukin
IL-2 - used for renal cell carcinoma, metastatic melanoma
Epoetin alfa (
Erythropoitein - used for anemia
Filgrastim
G-CSF - used to recovery bone marrow
Sargramostim
GM-CSF - used to recover bone marrow
