Tacrolimus is a macrolide immunosuppressant that is used to prevent organ rejection in transplant patients. It binds to the cytosolic protein, FKBP-12, which prevents calcineurin from dephosphorylating and activating nuclear factor of activated T cells (NFAT). Tacrolimus inhibits the production of IL-2 and other cytokines by T cells, suppressing proliferation. Tacrolimus has been shown to be bioequivalent when administered orally or intravenously. Bioavailability may be increased when taken with food.
