Mechanism of action

Tacrolimus is a calcineurin inhibitor that binds to FKBP12 and blocks calcineurin phosphatase activity, preventing dephosphorylation of NFAT and subsequent T-cell cytokine production. Envarsus XR is a once-daily extended-release formulation designed to improve bioavailability and reduce dosing frequency compared to immediate-release Prograf (tacrolimus), while maintaining immunosuppressive efficacy in transplant recipients.
