In this non-randomized extension study of a randomized controlled trial we converted 87 stable long-term kidney transplant recipients (KTR) from either ciclosporin (CSA, n = 28) or tacrolimus (TAC, n = 59) to TAC modified release (TAC MR4) to study the characteristics of TAC trough levels after conversion with the primary endpoint graft function after 12 months. TAC MR4 consumption was calculated by level-to-dose ([ng/mL]/[mg/d]) and concentration-to-dose ([mg/kg])/d) ratios. Influences of  ABCB1  single nucleotide polymorphisms (2677G>T/A, 1236C>T, 3435C>T) on TAC metabolism were studied. Graft function of KTR converted from CSA to TAC MR4 significantly declined over 12 months, and remained unchanged after conversion from TAC to TAC MR4. Conversion from CSA to TAC MR4 resulted in supra therapeutic- and conversion from TAC to TAC MR4 in low trough levels. We could not find associations of  ABCB1  genotypes and TAC MR4 trough levels. Adverse events and errors with TAC/TAC MR4 intake were common. In stable long-term KTR conversion from TAC to TAC MR4 is feasible. For conversion from CSA we suggest a rate of 1:40 for a rough estimation of TAC MR4 target doses.   Trial registration  PEP Study: Ethics committee N° 393/2004, EudraCT 2004-004209-98.
