摘要: 目的:研究2种盐酸二甲双胍缓释片在中国健康受试者中的生物等效性。方法:采用随机、开放、两周期、交叉设计,空腹试验36名、餐后试验23名健康受试者单次口服盐酸二甲双胍缓释片(0.5 g)试验制剂(T)与参比制剂(R),采用液相色谱-串联质谱(LC-MS/MS)法测定血浆中二甲双胍的血药浓度,应用WinNonlin 7.0软件计算药动学参数,SAS9.4软件进行统计分析。结果:空腹试验中试验制剂与参比制剂中二甲双胍的主要药动学参数,Cmax分别为(700.6±191.1)和(694.5±169.2)ng/mL,AUC0-t分别为(4 858.7±1 134.3)和(4 809.3±1 188.6)ng·h·mL-1,AUC0-∞分别为(5 010.9±1 114.5)和(4 962.5±1 184.1)ng·h·mL-1。餐后试验中试验制剂与参比制剂中二甲双胍的主要药动学参数Cmax分别为(738.4±121.9)和(738.0±128.7)ng/mL,AUC0-t分别为(7 558.3±1 271.8)和(7 761.5±1 486.0)ng·h·mL-1,AUC0-∞分别为(7 713.7±1 275.5)和(7 924.3±1 506.3)ng·h·mL-1。空腹试验二甲双胍受试制剂/参比制剂Cmax、AUC0-t和AUC0-∞几何均数的比值(GMR)分别为101.40%、101.77%、101.64%,其90%置信区间(90%CI)分别为92.16%~111.56%、93.36%~110.93%、93.58%~110.39%;餐后试验二甲双胍受试制剂/参比制剂Cmax、AUC0-t、AUC0-∞的GMR分别为100.83%、98.27%和98.28%,其90%CI分别为96.74%~105.10%,94.94%~101.71%,95.00%~101.68%。均完全落在80.00%~125.00%之间。结论:两种盐酸二甲双胍缓释片剂具有生物等效性。

Abstract: AIM: To study the bioequivalence of two metformin hydrochloride sustained-release tablets in Chinese healthy subjects.  METHODS: A randomized, open-label, two-period, crossover study design was adopted in the study. In fasting test 36 and in fed test 23 healthy subjects were given a single oral dose of metformin hydrochloride sustained-release tablet (0.5 g). The concentration of metformin in plasma was measured by HPLC-MS/MS. The pharmacokinetic parameters were calculated by WinNonlin 7.0 program, and statistical analysis were performed by using SAS9.4 statistics software. RESULTS: In the fasting test, the pharmacokinetic parameters of metformin of the test (T) and reference(R) preparation were as follow: Cmax were (700.6±191.1) and (694.5±169.2) ng/mL, AUC0-t were (4 858.7±1134.3) and (4 809.3±1 188.6) ng·h·mL-1, AUC0-∞ were (5 010.9±1 114.5) and (4 962.5±1 184.1) ng·h·mL-1. In the fed test, the pharmacokinetic parameters of T and R were as follow: Cmax were (738.4±121.9) and (738.0±128.7) ng/mL, AUC0-t were (7 558.3±1 271.8) and (7 761.5±1 486.0) ng·h·mL-1, AUC0-∞ were (7 713.7±1 275.5) and (7 924.3±1 506.30) ng·h·mL-1. In fasting condition, the 90% confidence interval (90%CI) of Cmax, AUC0-t and AUC0-∞ of metformin were 92.16%-111.56%, 93.36%-110.93% and 93.58%-110.39%. In fed condition, the 90%CI of Cmax, AUC0-t and AUC0-∞ of metformin were 96.74%-105.10%, 94.94%-101.71% and 95.00%-101.68%. All datas were in the area of 80.00%-125.00%. CONCLUSION: The two metformin hydrochloride sustained-release tablets were bioequivalent.
