ABSTRACT
<p><b>AIM</b>To investigate the pharmacokinetics of mycophenolic acid (MPA), an active metabolite of mycophenolate mofetil (MMF) in Chinese adult liver transplant patients.</p><p><b>METHODS</b>Thirty-eight liver transplant patients (male 30, female 8) receiving MMF 1.0 g, twice daily in accordance with the recommended regimen were included in this study. Plasma MPA concentrations were measured by high performance liquid chromatography at 0.5, 1, 1.5, 2, 4, 6, 8, 10 and 12 h after the administration of a single dose. Pharmacokinetic parameters were calculated with 3P97 software.</p><p><b>RESULTS</b>The plasma MPA concentration-time curve was characterized with an early sharp peak reached at 0.5 - 6.0 h after oral administration. And in some patients there was a small second peak due to enterohepatic circulation of mycophenolic acid glucuronide (MPAG), which underwent deglucuronidation and re-absorption as MPA at 4 to 12 h postdose. The mean peak plasma concentration (C(max)) and area under concentration-time curve (AUC(0-12 h)) were (12 +/- 7) microg x mL(-1) and (44 +/- 16) microg x h x mL(-1), respectively. However, a large variability of pharmacokinetic parameters existed in these patients.</p><p><b>CONCLUSION</b>In view of the inter-individual variability of MMF pharmacokinetics, plasma MPA concentration should be monitored routinely after MMF administration for individual patient.</p>
