摘 要:目的:建立高效液相色谱荧光法(HPLC-FLU)测定人血浆中坎地沙坦浓度并对其口服制剂进行生物等效性研究。方法:采用随机自身对照双周期交叉实验设计,19名健康受试者口服受试制剂和参比制剂后,用HPLC-FLU法测定人血浆中坎地沙坦浓度,用非房室模型估算坎地沙坦的药动学参数。结果:受试制剂和参比制剂的药动学参数如下:AUC_(0~t)分别为(1378.86±293.90)和(1338.33±324.76)μg·h·L^(-1);AUC_(0~∞)分别为(1451.48±299.56)和(1398.80±338.82)μg·h·L^(-1);C_(max)分别为(139.01±36.56)和(141.17±36.69)μg·L^(-1);t_(max)分别为(3.03±0.82)和(3.26±1.63)h;t_(1/2)分别为(8.30±2.06)和(8.17±1.43)h。受试制剂的相对生物利用度为(104.20±11.90)%。结论:经统计学分析,两种国产坎地沙坦酯片剂具有生物等效性。Objective: To study the pharmacokinetics and relative bioavailability of compound candesartan ester tablets by HPLCFLU in healthy volunteers. Method : Nineteen male healthy volunteers received tested and reference tablets orally in a random crossover design. Drug concentrations in plasma were determined by HPLC-FLU and the pharmaeokinetic parameters were estimated by non-compartment model. Result: The main pharmacokinetic parameters of tested and reference tablets were as follows:AUCo-1 of (1 378.86 ± 293.90) and (1 338.33±324.76) μg.h.L^-1, AUCo-∞ of (1 451.48±299.56) and (1 398.80±338.82) μg·h.L^-1, Cmax of (139.01 ±36.56) and (141.17±36.69) μg·L^-1, tmax of (3.03 ±0.82) and (3.26± 1.63) h, and t1/2 of (8.30 ±2.06) and (8. 17 ± 1.43) h, respectively. The relative bioavailability of the tested tablets was ( 104. 20 ±11.90) %. Conclusion: The results demonstrate that the two tablets are bioequivalent.
