Abstract
Objective To compare the pharmacokinetics of tacrolimus in kidney transplant patients treated with modified release and immediate release preparations . Methods It was a multi - centre, open label, 1:1 randomized, parallel, repeated - dose study. Adult kidney transplant recipients aged from 18-70 years were randomized into modified release group once daily (qd) and immediate release group twice a day (bid). A validated LC/MS/MS method was used to determine blood concentrations of tacrolimus. Results The mean daily dose for modified release (re = 17) was (0. 12 ±0. 05) mg ? Kg-1on day 56, and that for immediate release (re = 15) was (0. 10 ±0. 04) mg ? Kg-1. The parameters of tacrolimus for the two formulations at steady state were as follows; Cmax was (13. 20 ±4. 20) ng ? mL"'at (3. 10 ±3.00)h for modified release and (11.80±3.80) ng ? mL"'at (1.80 ±0.90) h for immediate release, Cmwas (4.40 ± 1.30) and (4.50 ± 1.20) ng ? mL-1, and AUCo.^was (171.70 ±49.90) and(145.10 ±29. 30) ng ? mL-1 ? H, respectively. The coefficient between AUC0 _M and CM was 0. 87 for modified release, and was 0. 62 for immediate release, respectively. Conclusion In patients undergoing primary kidney transplantation, daily doseof modified release tacrolimus increases 23% compared with that of immediate release on day 56 after operation, and the systemic exposure to tacrolimus over the 24 - hour interval is 16% higher. There is a good correlation between C24 and AUC0_24 for the modified release tacrolimus.关键词
