Fine Gran),采用单次口服、单中心、随机、开放、双周期、交叉设计,用HPLC-MS/MS法检测血浆中对乙酰氨基酚浓度,使用Phoenix WinNonlin 8.1软件及SAS 9.4软件分析生物等效性(BE)。结果:空腹组26例健康受试者分别单次空腹服用对乙酰氨基酚干混悬剂(受试制剂)和对乙酰氨基酚细粒剂(参比制剂)后,C_(max),AUC_(0~t)及AUC_(0~∞)的几何均数比值及其90%置信区间分别为100.72%(90.88%,111.63%),96.55%(92.80%,100.46%),95.58%(92.78%,98.48%),均落在等效区间80.0%~125.00%范围内。餐后组26例健康受试者在餐后口服对乙酰氨基酚干混悬剂(受试制剂)和对乙酰氨基酚细粒剂(参比制剂)后,C_(max),AUC_(0~t)及AUC_(0~∞)的几何均数比值及其90%置信区间分别为96.69%(89.52%,104.43%),98.27%(95.63%,100.98%),98.59%(96.01%,101.24%),均落在等效区间80.0%~125.00%范围内。结论:2种制剂在空腹和餐后条件下具有生物等效性。展开更多
