Prograf
Capsules: 0.5 mg
Capsules: 1 mg
Capsules: 5 mg
Injection: 5 mg/mL
Class: Immunosuppressive

  Action Suppresses cell-mediated immune reactions and some humoral immunity, but exact mechanism is not known.

  Indications

PO and IV: Prophylaxis of organ rejection in patients receiving allogenic liver or kidney transplants. Used in conjunction with adrenal corticosteroids.

Topical: Atopic dermatitis.

Prophylaxis of rejection for patients receiving kidney, bone marrow, cardiac, pancreas, pancreatic island cell, and small bowel transplantation.

  Contraindications Hypersensitivity to polyoxyl 60 hydrogenated castor oil, which is present in the injection.

  Route/Dosage

Prophylaxis of Organ Rejection Liver Transplants:

Adults: PO 0.1 to 0.15 mg/kg/day in 2 divided daily doses q 12 hr no sooner than 6 hr after transplantation. IV 0.03 to 0.05 mg/kg/day as continuous infusion.

Children: PO 0.15 to 0.2 mg/kg/day in 2 divided daily doses q 12 hr. IV 0.03 to 0.05 mg/kg/day as continuous infusion.

Prophylaxis of Organ Rejection Kidney Transplants:

Adults: PO 0.2 mg/kg/day in 2 divided daily doses q 12 hr, starting within 24 hr of transplantation but delayed until renal function is recovered (eg, serum creatinine of 4 mg/dL or less). Black patients may require higher doses to achieve comparable blood concentration.

Topical Dermatits:

Adults: Topical Apply thin layer of 0.03% and 0.1% to affected skin areas bid and rub in gently and completely; continue for 1 wk after clearing of atopic dermatitis.

Children at least 2 yr: Topical Apply thin layer of 0.03% to affected skin areas bid and rub in gently and completely; continue for 1 wk after clearing of atopic dermatitis.

  Interactions

Azole antifungal agents (eg, fluconazole, ketoconazole), calcium channel blockers (eg, diltiazem, nifedipine), clotrimazole, macrolide antibiotics (eg, erythromycin):

Tacrolimus plasma levels may be elevated, increasing the risk of toxicity.

Cyclosporine: Additive nephrotoxicity.

Hydantoins (eg, phenytoin): Tacrolimus plasma levels may be reduced, while hydantoin concentrations may be increased.

Mycophenolate mofetil: Plasma levels of mycophenolate mofetil may be elevated.

Rifamycins (eg, rifampin, St. John’s wort): Tacrolimus plasma levels may be reduced, increasing the risk of rejection.

  Lab Test Interferences None well documented.

PATIENT CARE CONSIDERATIONS

  Administration/Storage

  • Dilute IV form of the medication prior to use with 0.9% Normal Saline or 5% Dextrose Injection to a concentration between 0.004 mg/mL and 0.02 mg/mL.
  • Diluted solution must be stored in glass or polyethylene containers for up to 24 hr after mixing. Storage in PVC containers reduces stability.
  • Do not use solutions that contain particulate matter or are discolored.
  • The initial IV or oral dose of this medication should be no sooner than 6 hr after transplantation.
  • Switch patients to the oral form of the medication as soon as possible.
  • When converting from IV to oral dosage form, the first oral dose should be no sooner than 8 to 12 hr after discontinuation of IV administration.
  • Oral medication is most effective on an empty stomach.
  • Do not use this medication simultaneously with cyclosporine. Discontinue cyclosporine at least 24 hr before administering this drug.
  • Diluted IV solution may be stored at controlled room temperature.
  • Store capsules at room temperature.

  Assessment/Interventions

  • Obtain patient history. Note hypersensitivity to other antirejection drugs such as cyclosporine and polyoxyethylated castor oil.
  • Obtain baseline laboratory tests, including BUN, creatinine, lipid levels, potassium, WBC with differential and CBC. Perform and evaluate these tests periodically during treatment.
  • Assess for preexisting hypertension, particularly in children.
  • Assess for any signs of infection, bleeding, or bruising.
  • Remain with patient for the first 30 min of the initial IV administration of this medication and assess for symptoms of anaphylactic reaction. Assess frequently during all IV administrations.
