Pharmacokinetics of mycophenolic acid in Chinese kidney transplant patients

摘要

To assess the influence of cyclosporin A (CsA) and tacrolimus (FK506) on mycophenolic acid (MPA) and correlation analysis of the pharmacokinetic parameters and patient characteristics, clinical outcome in Chinese kidney transplant recipients, the pharmacokinetics of 1000 mg mycophenolate mofetil (MMF) twice daily was measured by high-performance liquid chromatography (HPLC). PKS (Pharmaceutical Kinetics Software) 1.0.2 software package was used for the calculation of pharmacokinetic parameters. The mean Cmax, tmax, and AUC(0−12)were (21.88±10.52) µg/ml, (1.20±0.95) h, and (52.546±13.215) µg·h/ml, respectively. The level of AUC(0−12) in the FK506 group was significantly higher than that in the CsA group. MPA appeared not to be affected by renal function. MPA AUC(0−12) showed statistically significant difference according to the patient’s gender.
