摘要: 目的:研究不同厂家生产的厄贝沙坦片的生物等效性。方法:18 名健康男性志愿者随机交叉单剂量口服不同厂家生产的厄贝沙坦片剂300 mg, 进行药代动力学和相对生物利用度研究。血药浓度采用高效液相色谱仪测定。结果:受试片剂和参比片剂的主要药代动力学参数Cmax 分别为(3147±922)、(2856±652) ng/mL;tmax 分别为(1.6±0.7)、(1.9±1.1) h;AUC0→t 分别为(17559±7482)、(17366±5498) ng°mL-1°h, AUC0→∞分别为(18276±7710)、(18284±5336) ng°mL-1°h;各参数间比较差异无统计学意义(P>0.05)。结论:以AUC0→∞计算平均相对生物利用度(F) 为101%±32%, 统计学结果显示两制剂生物等效。

Abstract: AIM: To study the pharmacokinetics and relative bioavailability of irbesartan tablets.METHODS: A single oral dose of 300mg irbesartan of reference or test tablet was given to each of 18 male healthy volunteers according to an open randomized crossover design.The concentrations of irbesartan in plasma were determined by HPLC.RESULTS: The main pharmacokinetic parameters of irbesartan showed that Cmax were (3147±922) and (2856±652) ng/mL, tmax were (1.6±0.7) and (1.9±1.1) h, AUC0→t were (17559±7482) and (17366± 5498) ng°mL-1°h, AUC0→∞ were (18276±7710) and (18284±5336) ng°mL-1°h for reference or test tablet respectively.There was no significant difference between the parameters of two tablets.CONCLUSION: The relative bioavailability of test tablet to reference tablet is 101%±32%.The results of statistical analysis show that two formulations are bioequivalent.
