摘要: 目的 研究头孢克罗泡腾片在健康志愿者体内的相对生物利用度。方法 采用双交叉试验,12名健康志愿者口服单剂量头孢克罗泡腾片和胶囊两种制剂0.75g,RP-HPLC法测定人血浆中头孢克罗浓度,药-时数据用ATPK拟合,按一室模型计算药物动力学参数。结果 泡腾片和胶囊Tmax分别为(0.58±0.12)和(0.73±0.17)h,Cmax分别为(31.27±5.81)和(30.56±5.25)μg·ml-1,AUC0~4分别为(35.5±4.65)和(35.9±2.90)μg·h·ml-1。试验品的相对生物利用度为(98.6±7.5)%。结论 头孢克罗泡腾片与胶囊生物等效。

Abstract: Aim To study relative bioavailablity of cefacloreffervescent tablets in healthy volunteers.Methods According to the crossover design, Avolunteers wereeach orally g iven a sing le does of the 0.75 g cefacloreffervescent tablets and cefaclor capsules with an interval of 5 days between the twoformulations.The plasma concentrations of the drug weredetermined by RP-HPLC.Pharmacokinetic parameters wereobtained by A TPK programe, and calculated on the basis of open sing le compartment model.Results After a single oral dose, the peak levels in plasma averaged Cmax(31.27±5.81) μg·ml-1 and(30.56±5.25) μg·ml-1 at (0.58±0.12) h and(0.73±0.17) h and AUC0~4(35.48±4.65) μg·h·ml-1 and (35.89±2.90) μg·h·ml-1 for tablet and capsule, respectively.Conclusion Theresult show s that twoformulations arebioequivalence.
