Immune drugs Flashcards
cyclosporine clinical use
suppresses organ rejection after transplantation
cyclosporin MOA : forms a complex with ?
cyclophilins
cyclosporine/cyclophilin complex MOA
block T cells activation and differentiation by inhibiting calcineurin= no IL-2 and cytokine
Cyclosporins toxicities
Nephrotoxicity HTN Hyperlipedemia hyperglycemia tremor gingival hyperplasia hirsutism
Tacrolimus MOA
Inhibits calceneurin by binding to the FK-binding protein
Tacrolimus clinical use
Potent immunosuppressant
Tacrolimus toxicities
same as cyclosporines except no hirsutism or gingival hyperplasia
Sicrolimus MOA
Inhibits mTOR leading to decreased T-cell proliferation
Sicrolimus in addition to immunosupressing is used for
Drug eluting stents
Sircolimus toxicities
Hyperlipidemia
thrombocytopenia
leukopenia
Azathioprine clinical use
Kidney transplants
AI diseases– glomerulonephritis and hemolytic anemia
Azathiprine is toxic to
proliferating lymphocytes
Azathioprine MOA
It is an antimetabolite precursor of 6-mercaptopurine that interferes with synthesis of nucleic acid
Azathioprine toxicities
Bone marrow suppression
Why is azathioprine toxicity worse with allopurinol
because its active metabolite 6MCP is metabolized by xanthine oxidase
