摘 要 目的 评价健康受试者餐后口服两种双醋瑞因胶囊的生物等效性。方法 共纳入24名成年健康受试者,随机分为两组,
每组12名。采用随机、开放、双周期交叉试验设计,两组患者于每周期试验首日早晨进食标准餐30 min后,分别口服受试制剂(国
产双醋瑞因胶囊)和参比制剂(安必丁 )50 mg,清洗期为1周。分别于服药前后不同时间点采集血样,用甲醇沉淀蛋白进行样品

ABSTRACT OBJECTIVE To evaluate the postprandial bioequivalence of two kinds of Diacerein capsules in healthy volunteers
with oral administration. METHODS A total of 24 adult healthy subjects were included and randomly divided into two groups,
with 12 subjects in each group. A randomized,open,double-cycle cross-over trial design was adopted. Both groups took 50 mg of
the test preparation(domestic Diacerein capsules)or the reference preparation(Ambridine )respectively at 30 min after eating the
®
standard meal in the morning of the first day of each cycle of the trial. The cleaning period was one week. Blood samples were
collected at different time points before and after taking the medicine and the protein was precipitated with methanol for sample
pretreatment. The concentration of active metabolite rhein was determined by LC-MS/MS using emodin as internal standard. The
pharmacokinetic parameters were calculated with DAS 3.2.9 software,and the bioequivalence of test and reference preparation were
evaluated. RESULTS After the subjects took the test preparation and the reference preparation after meal, the main
pharmacokinetic parameters of rhein were as follows:cmax were(3 517±1 121)and(3 225±755)ng/mL;AUC0-24 h were
(25 764±6 134)and(24 316±5 856)ng·h/mL;AUC0-∞ were(26 679±6 409)and(25 170±6 415)ng·h/mL;tmax were 3.50
(0.67,12.00)and 4.00(1.50,7.00)h;t1/2 were(4.26±1.12)and(4.19±1.05)h,respectively. The 90% confidence intervals of the
geometric mean ratios of cmax,AUC0-24 h and AUC0-∞ were 100.8%-113.9%,103.1%-109.4% and 103.2%-109.9%,respectively.
CONCLUSIONS The test preparation and reference preparation are bioequivalent in the postprandial state of healthy subjects.
