Pharmacokinetics and Tissue Distribution of HCPT Capsules in Mice |
| |
Abstract: | ![]() OBJECTIVE:To study the pharmacokinetics and tissue distribution of hydroxycamptothecine(HCPT) capsules in mice METHODS:The contents of HCPT in mouse plasma and tissues were determined by fluorescence spectrophotometry The pharmacokinetic parameters were measured RESULTS:The calibration curves of HCPT revealed linearity in the range 0 01~0 5μg/ml The plasma concentration-time curves of HCPT capsules conformed to two-conpartment model of pharmacokinetics The major pharmacokinetic parameters were:T1/2α 0 29h,T1/2β 1 64h,AUC0~24 14 73μg/ml and CL 12 53ml/h HCPT in gastrointestinal tissue AUCpo>AUCiv,P<0 05,but in whole body blood AUCpo
