摘要: 目的 比较国产、进口阿斯咪唑混悬剂在健康中国人体的药代动力学。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混悬剂进行健康中国人体的药代动力学的比较, 并求相对生物利用度。结果 经3P87 软件处理, 阿斯咪唑的药代动力学呈二室模型。主要药代动力学参数:国产剂:Vd =6.88 ±1.36 L; αT1/2 =4.24 ±4.06 h; βT1/2 =170.31 ±73.80 h; CL =0.067±0.023 ng/ml; Tpeak =1.00 ±0.53 h; Cmax =1.25 ±0.17 ng/ml; AUC =162.97±48.57 ng/ml·h-1 。进口片: Vd =6.40 ±3.07 L; αT1/2 =1.31 ±0.91 h; βT1/2 =156.02 ±120.74 h; CL =0.079±0.045 ng /ml; Tpeak =1.00 ±0.53 h; Cmax =1.08 ±0.19 ng/ml; A UC =173.46 ±114.66 ng/ml·h-1结论 国产、进口阿斯咪唑混悬剂在中国人体的药代动力学参数均未发现明显差异。

Abstract: Aim To compare the pharmacokinetic parameters of the domestic astemizole suspension with those of the imported product in Chinese healthy volunteers. Methods Astemizole and demethylastemizole concentration was measured by radioimmunoassay in a clinical trial of crossover design. Results The main pharmacokinetic parameters of the domestic product calculated by practical pharmacokinetics program 87 were Vd =6.88 ±1.36 L; αT1/2 =4.24 ±4.06 h; βT1/2 =170.31 ±73.80 h; CL =0.067±0.023 ng/ml; Tpeak =1.00 ±0.53 h; Cmax =1.25 ±0.17 ng/ml; AUC =162.97±48.57 ng/ml·h-1, while the parameters of the i mport ed product were Vd =6.40 ±3.07 L; αT1/2 =1.31 ±0.91 h; βT1/2 =156.02 ±120.74 h; CL =0.079±0.045 ng /ml; Tpeak =1.00 ±0.53 h; Cmax =1.08 ±0.19 ng/ml; A UC =173.46 ±114.66 ng/ml·h-1. The relative bioavailability of the domestic suspension was 90.5%. Conclusion No significant pharmacokinetic difference has been found between the domestic and the imported as temizole suspensions.
