摘要

本实验室曾证明

钙拮抗药硝苯吡啶对人和大鼠肝微粒体代谢（-）-和（+）-吡喹酮均有竞争性抑制作用。为进一步探明硝苯吡啶在体内对吡喹酮代谢的影响

本实验以硝苯吡啶40mg/kg

ip单剂给药后

采用反相高效液相色谱法测定消旋吡喹酮（100mg/kg

ig）在大鼠体内的血浆浓度

所得药代动力学参数:AUC、MRT、CL、T

in、C

与对照组相比均无显著差异

表明在该剂量下硝苯吡啶ip单剂给药对吡喹酮存大鼠体内的药代动力学无明显影响

Abstract

A previous study in our laboratory had shown that n ifedipine(NF) as acalci-um antagonist

competitively inhibited the metabolism of praziquantel (PQT) enantiomers in human and rat liver microsomes in vitro. In this paper

we studied the effect of NF on the plasma concentration of PQT in rats. After Ig injections of PQT 100 mg/kg to male Wistar rats

the plasma levels of PQT were determined by reverse HPLC. The results shown by

(that)tho pharmacokinetic parameters (AUC

MRT

Tmax and Cmax) of PQT in NF (a single ip injection of 40 mg/kg) -pretreated rats were not significantly differ3nt as compared with that of control rats. The data from our investigation demonstrated that NF had no effects on the pharmacokinetics of PQT in rats in vivo
