Tacrolimus-2D-skeletal

What are the uses of this medicine?[edit | edit source]

  • Tacrolimus capsules are a prescription medicine used with other medicines to help prevent organ rejection in people who have had a kidney, liver, or heart transplant.
  • Tacrolimus capsules are a type of tacrolimus immediate-release drug and they are not the same as tacrolimus extended-release tablets or tacrolimus extended-release capsules. Your healthcare provider should decide what medicine is right for you.

How does this medicine work?[edit | edit source]

  • Tacrolimus (ta kroe' li mas), also known as FK506, is a macrolide antibiotic which also has profound immunosuppressive properties, particularly affecting T cells and the cellular immune response.
  • Tacrolimus acts as a calcineurin inhibitor which is responsible for activating an important signal transduction molecule in the pathway of T cell activation.
  • The result of the inhibition is a decrease in maturation of T lymphocytes and reduction in lymphokine production, including IL-2.
  • Tacrolimus also inhibits IL-2 receptor expression and nitric oxide release, induces apoptosis and production of transforming growth factor beta that can lead to immunosuppressive activity.
  • The net result is the inhibition of T-lymphocyte activation and proliferation, as well as T-helper-cell-dependent B-cell response (i.e., immunosuppression).

Instruct patients or caregivers to recognize the appearance of tacrolimus capsules.

  • Tacrolimus, like other calcineurin inhibitors, can cause acute or chronic nephrotoxicity. Reduce the dose; use caution with other nephrotoxic drugs.
  • Tacrolimus may cause a spectrum of neurotoxicities. Including risk of Posterior Reversible Encephalopathy Syndrome (PRES); monitor for neurologic abnormalities; reduce or discontinue tacrolimus capsules.
  • Hyperkalemia has been reported with tacrolimus use. Monitor serum potassium levels. Consider carefully before using with other agents also associated with hyperkalemia.
  • Hypertension is a common adverse effect of tacrolimus therapy. May require antihypertensive therapy. Monitor relevant drug-drug interactions.
  • Anaphylactic reactions have occurred with injectables containing castor oil derivatives, including tacrolimus injection. Observe patients receiving tacrolimus injection for signs and symptoms of anaphylaxis.
  • Tacrolimus is not recommended for use with sirolimus. Not recommended in liver and heart transplant due to increased risk of serious adverse reactions.
  • When co-administering tacrolimus with strong CYP3A4 inhibitors (e.g., telaprevir, boceprevir, ritonavir, ketoconazole, itraconazole, voriconazole, clarithromycin) and strong inducers (e.g., rifampin, rifabutin), adjustments in the dosing regimen of tacrolimus and subsequent frequent monitoring of tacrolimus whole blood trough concentrations and tacrolimus-associated adverse reactions are recommended.
  • Myocardial hypertrophy has been reported in infants, children, and adults, particularly those with high tacrolimus. Consider dose reduction/discontinuation.
