摘要: 目的:以泮托拉唑钠肠溶片为对照药,评价左旋泮托拉唑钠肠溶片在健康受试者体内的药动学和药效学。方法:采用随机、开放、阳性药对照试验设计,30名健康受试者分为3组,分别单次和多次给予20 mg、40 mg左旋泮托拉唑钠和40 mg泮托拉唑钠肠溶片,采用LC-MS/MS法测定左旋泮托拉唑血药浓度,计算其药代动力学参数;监测胃内24 h pH值,评价药物的量效关系。 结果:单次给药20 mg、40 mg左旋泮托拉唑钠和40 mg泮托拉唑钠肠溶片后左旋泮托拉唑的主要药动学参数Cmax分别为(1 635±410)、(2 756±1 024)和(1 536±615)ng/mL,t1/2分别为(1.41±0.31)、(1.55±0.64)和(1.35±0.22)h,AUC0-t 分别为(3 623±1 322)、(7 383±3 785)和(3 276±1 302)h·ng·mL-1;多次给药后主要药动学参数:Cmax分别为(1 704±239)、(3 297±743)和(1 832±557)ng/mL,t1/2分别为(1.41±0.40)、(1.58±0.64)和(1.45±0.22) h,AUC0~t分别为(3 587±1 040)、(8 189±3 399)和(3 878±1 272)h·ng·mL-1。单次给药后pH>4.0的时间百分比分别为(32.98±10.7)%、(45.37±9.61)%、和(32.63±14.63)%;多次给药后pH>4.0的时间百分比分别为(45.12±11.97)%、(50.76±10.63)%和(41.67±7.1)%。结论:健康受试者单次和多次给药后左旋泮托拉唑呈线性动力学特征,而40 mg左旋泮托拉唑钠组的药效优于其他剂量组,健康受试者对药物的耐受性良好。

Abstract: AIM: To evaluate the pharmacokinetics and pharmacodynamics of (S)-pantoprazole sodium enteric-coated tablets in healthy subjects by using pantoprazole sodium enteric-coated tablets as a control drug.  METHODS: Thirty healthy Chinese subjects were enrolled in a randomized, open and positive control trial. The subjects were given 20 and 40 mg (S)-pantoprazole sodium enteric-coated tablets and 40 mg pantoprazole sodium enteric-coated tablets, respectively. The concentration of (S)-pantoprazole in the human plasma was determined by LC-MS/MS and the pharmacokinetic parameters were calculated by WinNonlin 6.4 software. The intragastric pH was monitored for 24 hours. The dose-effect relationship of drugs was evaluated. RESULTS: The main pharmacokinetic parameters of (S)-pantoprazole after single administration of 20 and 40 mg (S)-pantoprazole sodium and 40 mg pantoprazole sodium enteric-coated tablets were as follows: The Cmax were (1 635±410), (2 756±1 024) and (1 536±615) ng/mL, the t1/2 were (1.41±0.31), (1.55±0.64) and (1.35±0.22) h, the AUC0-t  were (3 623±1 322), (7 383±3 785) and (3 276±1 302) h·ng·mL-1; The main pharmacokinetic parameters of multiple administration were as follows: The Cmax were (1 704±239), (3 297±743) and (1 832±557) ng/mL, the t1/2 were (1.41±0.40), (1.58±0.64) and (1.45±0.22) h, the AUC0-t  were (3 587±1 040), (8 189±3 399) and (3 878±1 272) h·ng·mL-1. After the treatment, the time of pH>4.0 as a percentage of total time (%) after single administration were (32.98±10.7)%, (45.37±9.61)% and (32.63±14.63)%; and the time of pH>4.0 as a percentage of total time (%) after multiple administration were (45.12±11.97)%, (50.76±10.63)% and (41.67±7.1)%. CONCLUSION: Healthy subjects have linear kinetic characteristics of (S)-pantoprazole after single and multiple administrations, and the 40 mg (S)-pantoprazole sodium group has better efficacy than other dose groups. Healthy subjects were well tolerated.
