摘 要:目的建立超高效液相色谱-串联质谱(UHPLC-MS/MS)法测定人血浆中塞来昔布的浓度,研究两种塞来昔布胶囊的药动学及在中国健康人体内的生物等效性。方法采用随机、开放、两周期、两序列、双交叉设计,空腹试验和餐后试验各36例健康受试者,单剂量口服塞来昔布胶囊受试制剂和参比制剂0.2 g。采用UHPLC-MS/MS法测定血浆中塞来昔布浓度,色谱柱Kinetex C18 100A (50 mm×2.1 mm,2.6μm);0.2%甲酸的水溶液(A)-含0.2%甲酸的乙腈溶液(B)为流动相,梯度洗脱,流速0.3 m L·min^-1;电喷雾电离源,负离子多反应离子监测(MRM),塞来昔布与内标(塞来昔布-d7)的离子对m/z分别为380.0/315.9和387.2/323.0。经Win Non Lin 8.0软件统计,非房室模型法计算药动学参数,并判定两制剂是否等效。结果空腹试验中受试制剂和参比制剂的主要药动学参数cmax分别为(552±251)、(571±324)μg·L^-1,tmax分别为3.00(1.00,5.00)、2.50 (1.00,5.00) h;t1/2分别为(11.40±4.71)、(15.78±18.17) h;AUC0-t分别为(6 096.45±3 529.51)(5 718.79±3 227.17)μg·h·L^-1;AUC0-∞分别为(6 350.34±3 765.24)、(6 223.45±3 455.96)μg·h·L^-1。餐后试验中受试制剂和参比制剂的主要药动学参数cmax分别为(1 610±554)、(1 460±476)μg·L^-1;tmax分别为5.00 (1.50,5.50)、5.00 (1.50,5.50)h;t1/2分别为(5.61±1.80)、(5.54±1.74) h;AUC0-t分别为(9 816.87±3 094.32)、(9 518.57±2 983.02)μg·h·L^-1;AUC0-∞分别为(9 870.43±3 104.96)μg·h·L^-1、(9 574.63±2 998.23)μg·h·L^-1。受试制剂与参比制剂的AUC0-t、AUC0-∞和cmax几何均值比值的90%置信区间均在80%-125%之间。结论本研究建立的UHPLC-MS/MS法能快速、准确测定人血浆中塞来昔布的浓度,两种塞来昔布胶囊生物等效。AIM To establish a UHPLC-MS/MS method for the determination of the concentration of celecoxib in human plasma,and evaluate the pharmacokinetics and the bioequivalence of two celecoxib capsules in Chinese healthy volunteers.METHODS In a random,open,2 periods,2 sequence,self-crossover study,thirty-six healthy volunteers in fasting test and thirty-six healthy volunteers in fed test were given single oral dose of celecoxib capsule 0.2 g.The concentrations of celecoxibin plasma were determined by a UHPLC-MS/MS method.The column was Kinetex C18 100A(50mm×2.1 mm,2.6μm) and the mobile phase consisted of 0.2%formic acid in water (A) and 0.2%formic acid in acetonitrile(B) with gradient elution;the flow rate was set as 0.3 m L·min^-1.Electrospray ionization source with negative ion multiple reactive ion monitoring (MRM) were used,and ion pair m/z of celecoxib and internal standard (celecoxib-d7) were 380.0/315.9 and 387.2/323.0,respectively.The pharmacokinetic parameters of celecoxib were calculated with non-compartmental analysis method using Win Non Lin 8.0,and the bioequivalence was assessed.RESULTS In fasting test,the pharmacokinetic parameters of celecoxib of the test(T) and reference(R) preparation were as follow:the cmax were (552±251)μg·L^-1and (571±324)μg·L^-1,the tmax were 3.00 (1.00,5.00) h and 2.50 (1.00,5.00) h,the t1/2 were (11.40±4.71) h and(15.78±18.17) h,the AUC0-t were (6 096.45±3 529.51)μg·h·L^-1 and (5 718.79±3 227.17)μg·h·L^-1,the AUC0-∞were (6 350.34±3 765.24)μg·h·L^-1 and (6 223.45±3 455.96)μg·h·L^-1.In fed test,the pharmacokinetic parameters of celecoxib of T and R were as follow:the cmax were (1 610±554)μg·L^-1 and (1 460±476)μg·L^-1,the tmax were 5.00(1.50,5.50) h and 5.00 (1.50,5.50) h,the t1/2 were (5.61±1.80) h and (5.54±1.74) h,the AUC0-t were (9 816.87±3 094.32)μg·h·L^-1 and (9 518.57±2 983.02)μg·h·L^-1,AUC0-∞were (9 870.43±3 104.96)μg·h·L^-1 and(9 574.63±2 998.23)μg·h·L^-1.The 90%confidence intervals of geometric mean ratio for AUC0-t,AUC
