Abstract

Nonadherence to immunosuppressive regimens among solid organ transplantation to range has been estimated from 15% to 55%. This problem has been identified as a leading cause of preventable graft loss. Tacrolimus once daily Advagraf has been developed to provide a more convenient dosing regimen to improve adherence. The aim of this study was to analyze the safety of a 1:1 dose conversion from twice-daily tacrolimus (Prograf) to Advagraf in 36 stable liver transplant recipients. The tacrolimus whole blood trough level at T0 was 6.7 +/- 2.9 ng/mL with a daily dose of 3.7 +/- 1.8 mg. The mean tacrolimus blood trough levels at T1 (7 days) and T2 (14 days) were 5.8 +/- 2.5 and 5.8 +/- 1.8 ng/mL with mean daily doses of 3.9 +/- 1.9 and 4.1 +/- 1.8 mg, respectively. There was no significant difference between T0, T1, and T2, either for tacrolimus blood trough levels or for tacrolimus daily dosages. Liver and renal function tests remained stable; no episodes of acute rejection were encountered after the conversion. A switching policy using a dose ratio of 1:1 from twice-daily tacrolimus to once-daily prolonged-release tacrolimus was safely applied to stable liver transplant recipients.
