摘要
目的探讨性别对肾移植患者霉酚酸酯(MMF)药代动力学的影响。方法纳入肾移植科手术患者178例。当体内药物浓度到达稳态后,于服药后0.5,1.5,4和9 h取患者静脉血,用高效液相色谱法测定血浆中MMF代谢物霉酚酸(MPA)和葡萄糖醛酸霉酚酸(MPAG)浓度,估算0-12 h血药浓度-时间曲线下面积(AUC0-12 h)。结果女性剂量调整MPA AUC0-12 h(46.24±2.98)mg·h·L-1·g-1,显著高于男性的(35.36±1.61)mg·h·L-1·g-1(P〈0.01);而MPAG/MPA女性(15.24±1.05)显著低于男性(18.68±0.87)(P〈0.05)。此外,女性年龄与剂量调整MPA AUC0-12 h呈负相关(P〈0.05),45岁以下年龄组的剂量调整MPA AUC0-12h(49.74±3.58)mg·h·L-1·g-1,显著高于45岁以上年龄组的(33.69±2.49)mg·h·L-1·g-1(P〈0.05)。结论在中国肾移植患者中,MMF体内代谢存在性别差异,且女性体内药物代谢与年龄相关。
Objective To investigate the gender- related differences of mycophenolate mofetil pharmacokinetics in Chinese renal transplant patients. Methods A total of 178 renal transplant patients were included in the study. Blood samples were taken at 0. 5,1. 5,4 and 9 hours after the morning dose. A validated HPLC method was used to simultaneously detect MPA and MPAG concentrations in plasma,and AUC0- 12 hof MPA and MPAG were calculated. Results The dose- adjusted AUC0- 12 hof MPA was significantly higher in female patients( 46. 24 ± 2. 98)mg·h·L- 1·g- 1than that in male patients( 35. 36 ± 1. 61) mg·h·L- 1·g- 1( P〈 0. 05),while MPAG/MPA ratio was the opposite( 15. 24 ± 1. 05 vs.18. 68 ± 0. 87,P〈 0. 05). What's more,there was a negative correlation between age and dose- adjusted AUC0- 12 hof MPA( P〈 0. 05) in female patients. Younger female( age 45) patients had higher dose- adjusted AUC0- 12 hof MPA( 49. 74 ± 3. 58) mg · h · L- 1·g- 1than older female( age 45) patients( 33. 69 ± 2. 49) mg·h·L- 1·g- 1( P〈 0. 05).Conclusion Gender- related differences in MMF pharmacokinetics were found in our study,and dose- adjusted AUC0- 12 hof MPA was negatively correlated with age in female patients.
