液相色谱-质谱/质谱联用法测定苯唑西林浓度及其胶囊剂人体生物等效性的研究

目的:建立液相色谱-质谱/质谱联用法( LC-MS/MS)测定人血浆中苯唑西林的浓度,研究苯唑西林钠胶囊与参比制剂苯唑西林钠胶囊(奇菲)的生物等效性。方法:采用随机、单剂量、双交叉对照试验设计,20名男性健康志愿者空腹口服受试及参比制剂1000 mg,采用蛋白沉淀法处理血浆样品,使用LC-MS/MS法测定血浆中苯唑西林的浓度,并以DAS 2.0软件进行方差分析及双单侧t检验,判断2种制剂是否具有生物等效性。结果:口服受试及参比制剂后,血浆中苯唑西林峰浓度(Cmax)分别为(17.0±2.77)、(15.5±3.46)μg/ml;达峰时间(tmax)分别为(0.63±0.14)、(0.72±0....

OBJECTIVE:To determine human plasma concentration of oxacillin by liquid chromatography -mass spectrometry ( LC-MS/MS ) and study the bioequivalence of the tested and the standard preparations of oxacillin sodium capsules.METHODS:In a randomized, single dose and double crossover design, 20 healthy male volunteers were administered orally with tested and reference oxcillin sodium capsules ( 1 000 mg ) .The plasma samples were treated by of protein precipitation method, and the plasma concentrations of oxacillin within 6 hours after administration were determined by LC-MS/MS;DAS 2.0 software was employed for analysis of variance and two one-sided t-test for evaluation of the bioe
