目的:评价在中国人群中单次和多次给药后西格列汀的药代动力学特征。方法用开放、平行试验设计。16名健康受试者口服西格列汀100 mg,采集系列血、尿样本。用 LC -MS/MS 法测定西格列汀在血浆和尿液中的浓度,用WinNonlin非房室模型计算药代动力学参数。结果100mg单次给药后西格列汀的主要药代动力学参数如下:tmax为3 h(0.5~5 h),AUC0-t为(2.9±0.4)μg? mL-1? h,AUC0-∞为(3.2±0.5)μg? mL-1? h, Cmax 为(0.4±0.1)μg? mL-1,CL/F为(32.2±4.5) L? h-1, Vz/F 为(496.0±109.0) L, t1/2为(10.8±2.4)h;24 h尿液累积排泄率为(66.3±6.1)%。多次给药达到稳态后西格列汀的主要药代动力学参数如下:tmax为3 h (0.5~6 h), AUC0-t为(3.4±0.5)μg? mL-1? h, AUC0-∞为(3.4±0.5)μg? mL-1? h, Cmax 为(0.4±0.1)μg? mL-1,CL/F为(29.8±3.7) L? h-1,Vz/F为(445.0±81.2) L, t1/2为(10.4±1.7) h, RAUC为1.08, RCmax为1.02;24 h 尿液累积排泄率为(73.4±6.0)%。结论中国人西格列汀100 mg单次和多次给药的药代动力学特征与高加索人、日本人相似。

Objective To evaluate the pharmacokinetics characters of single-dose and multiple-dose of sitagliptin in Chinese.Methods An open -labelled, parallel study was designed.16 healthy males and females received sitagliptin tablet 100 mg.Blood and urine samples were collected.Sitagliptin in plasma and urine was analyzed by LC-MS/MS. WinNonlin non-compartment model was used to calculate the pharmaco-kinetics parameters.Results Following single administrating of sitaglip-tin:tmax was 3 ( 0.5 -5 ) h, AUC0-t was ( 2.9 ±0.4 )μg? mL-1? h, AUC0-∞ was ( 3.2 ±0.5 ) μg? mL-1 ? h, Cmax was ( 0.4 ±0.1 )μg? mL-1, CL/F was(32.2 ±4.5)L? h-1, Vz/F was(496.0 ±109.0) L, t1/2 was(10.8 ±2.4) h; urine excretion percentage during 24 h was (66.3 ±6.0 )%.Following multiple administrating of sitagliptin: tmax was 3(0.5-6)h, AUC0-t was(3.4 ±0.5)μg? mL-1? h, AUC0-∞was (3.4 ±0.5)μg? mL-1? h, Cmax was(0.4 ±0.1)μg? mL-1, CL/F was( 29.8 ±3.7 ) L? h-1 , Vz/F was ( 445.0 ±81.2 ) L, t1/2 was (10.4 ±1.7)h, RAUC was 1.08, RCmax was 1.02; urine excretion percentage during 24 h was(73.4 ±6.0 )%.Conclusion The pharmacokinetics parameters of sitagliptin in Chinese healthy volunteers were equivalent to historical data from Caucasian and Japanese.
