摘要: 目的 观察阿斯咪唑片剂的人体药代动力学和生物利用度。方法 用放射免疫法测定血浆阿斯咪唑+去甲阿斯咪唑含量,按交叉设计法对国产和进口阿斯咪唑片进行健康中国人体的药物代谢学比较研究,并求得相对生物利用度。用3P87软件处理。结果与结论 阿斯咪唑的药代动力学呈二室模型。主要药代动力学参数:国产片:Vd=5.34±1.85L;αT1/2=0.74±0.37h;βT1/2=286.10±220.11h;CL=0.052±0.031ng/ml;Tmax=1.56±1.32h;Cmax=1.04±0.10ng/ml;AUC=262.69±162.18ng/ml·h-1。进口片:Vd=8.24±2.56L;αT1/2=1.16±0.98h;βT1/2=260.38±260.37h;CL=0.089±0.079ng/ml;Tmax=1.37±0.82h;Cmax=0.93±0.14ng/ml;AUC=250.66±148.05ng/ml·h-1。国产片对进口片的相对生物利用度为127.8%。

Abstract: Aim and Methods Thepharmacokinetics and bioavailability of thedomestic and theimported astemizole tablets were studiedin 6 Chinese healthy volunteers by radioimmunoassay in a clinical trial of cross-over design.Results Themain pharmacokinetic parameters calculated by thepractical pharmacokinetics program 87 wereas follow s:For thedomestic product, Vd=5.34±1.85 L;αT1/2=0.74±0.37 h;βT1/2=286.10±220.11 h;CL=0.052±0.031 ng/ml;Tmax=1.56±1.32 h;Cmax=1.04±0.10 ng/ml;AUC=262.69±162.18 ng/ml·h-1.For theimported product, V d=8.24±2.56 L;αT1/2=1.16±0.98 h;βT1/2=260.38±260.37 h;CL=0.089±0.079 ng/ml;Tmax=1.37±0.82 h;Cmax=0.93±0.14 ng/ml;AUC=250.66±148.05 ng/ml·h-1.Therelative bioavailability of thedomestic tablets was 127.8 %.Conclusion No signif icant pharmacokine tic difference has been found be tw een thedomestic andimpor ted astemizole tablets.
