摘要: 目的 研究口服国产青霉素V 钾分散片在健康志愿者体内药代动力学和相对生物利用度。方法 12名健康志愿者双交叉口服单剂量国产青霉素V 钾分散片和进口片剂0.75 g, 用RP-HPLC 法测定人血浆中青霉素V 浓度, 药-时数据用ATPK 程序拟合,按一室模型计算药物动力学参数。结果 国产分散片和进口片剂t1/2(ke) 分别为(0.75 ±0.10) 和(0.70±0.14) h, tmax 分别为(0.56 ±0.11) 和(0.63±0.17) h, cmax分别为(8.44 ±2.40) 和(8.75±3.04)mg·L-1, AUC0~4 分别为(9.68 ±2.91) 和(10.62±2.71) mg·h·L-1。国产制剂的相对生物利用度为(90.5 ±8.8) %。结论 国产青霉素V 钾分散片与进口片剂具有生物等效性。

Abstract: Aim To study pharmacokinetics and bioavailablity of domestic penicillin V dispersion tablet in healthy volunteers. Methods According to the crossover design, each volunteer in two groups was orally given a single dose (0.75 g) of domestic penicillin V dispersion tablet or imported penicillinV tablet alternately and the plasma concentrations were determined by RP-HPLC. The pharmacokinetic parameters were obtained by using ATPK program and calculated on the basis of open single compartment model. Results After a single oral dose (0.75 g), the t1/2(ke) was (0.75 ±0.10) h and (0.70 ±0.14) h, the cmax was (8.44 ±2.40) mg·L-1 and (8.75 ±3.04) mg·L-1 at (0.56 ± 0.11) h and (0.63 ±0.17) h and AUC0~4 was (8.44 ±2.40) mg·h·L-1 and (8.75 ±3.04) mg·h·L-1 for two formulations, respectively. Relative bioavailability of domestic penicillin V dispersion tablet was (90.50 ±8.84) %.Conclusion The result shows that the two formulations are bioequivalent.
