Key Points

  • Immunosuppressants
    • Drug Names
      • Cyclosporine
      • Tacrolimus
      • Mycophenolate
      • Sirolimus
    • Mechanism
      • Multiple mechanisms
        • Cyclosporine and tacrolimus act as calcineurin inhibitors
          • Inhibits T cell differentiation and activation
        • Mycophenolate acts to inhibit IMP dehydrogenase, reducing immune cell differentiation and proliferation
        • Sirolimus acts to inhibit mTOR, needed for T-cell signaling
    • Clinical Use
      • Prevent organ transplant rejection
        • Immunosuppressants are the standard of care after receiving foreign organ transplants
      • Anti-inflammatory
        • May be used to treat severe refractory autoimmune diseases (e.g. rheumatoid arthritis, psoriasis)
        • This use case is less common due to severe immunosuppression and side effects
    • Side Effects and Adverse Reactions
      • Avoid grapefruit juice
        • Grapefruit juice increases drug levels of cyclosporine, tacrolimus, and sirolimus, and can lead to toxicity
      • Immunosuppression
        • Increased risk of infection
        • Do not receive live vaccines
        • Avoid large crowds
        • Immunosuppression also increases risk for developing cancer due to loss of immune surveillance
      • Gingival hyperplasia (cyclosporine)
      • Hirsutism (cyclosporine)
        • Increased hair growth
      • Hypertension (cyclosporine)
      • Kidney toxicity (cyclosporine, tacrolimus)
