Mechanism of action

Tacrolimus binds to the immunophilin FKBP12 and inhibits calcineurin, a phosphatase required for dephosphorylation and nuclear translocation of NFAT (nuclear factor of activated T cells). This prevents IL-2 and other cytokine gene transcription, thereby suppressing T-cell mediated immune responses. The SR (sustained-release) formulation provides prolonged drug exposure with potentially improved tolerability and compliance compared to immediate-release formulations.
