摘 要:目的 研究中国健康受试者单/多次口服盐酸头孢卡品酯片的药动学.方法 将30例受试者随机分为3组,每组10例,男女各半,一组进行盐酸头孢卡品酯片低剂量(100 mg)的单/多次给药人体药动学试验,受试者每天服药3次,每次100 mg,一共服药12次;一组进行盐酸头孢卡品酯片中剂量(200 mg)的单次给药人体药动学试验;一组进行盐酸头孢卡品酯片高剂量(300 mg)的单次给药人体药动学试验.采用高效液相色谱-串联质谱(HPLC-MS/MS)法测定活性代谢产物头孢卡品的血浓度,采用DAS 2.0版软件计算其主要药动学参数,采用SPSS 17.0版软件对主要参数进行统计分析.结果 单次空腹口服盐酸头孢卡品酯片100,200和300 mg后主要药动学参数:tmax分别为(1.42±0.54),(1.80±0.59)和(2.10±0.81) h;t1/2分别为(1.45±0.17),(1.60±0.22)和(1.44±0.18) h;MRT0-12 h分别为(2.75±0.42),(2.99±0.33)和(3.31±0.57) h;Cmax分别为(1 419±384),(2 128±366)和(2 438±655) μg·L-1;AUC0-12 h分别为(4 369±1 078),(7 477±1 616)和(9 091±3 735) μg·h·L-1;AUC0-∞分别为(4 389±1 080),(7 528±1 640)和(9 146±3 749) μg·h·L-1;V/F分别为(52.13±21.81),(63.60±14.78)和(76.06±23.29) L;CL/F分别为(24.27±7.06),(27.61±5.42)和(36.49±10.31) L·h-1.多次口服盐酸头孢卡品酯片100 mg后主要药动学参数:tmax为(1.90±0.70) h;t1/2为(1.63±0.16) h;MRT0-12 h为(2.87±0.52) h;Cssmax为(1 133±200) μg·L-1;AUCss为(3 607±730) μg·h·L-1;AUC0-12 h为(3 731±775) μg·h·L-1;AUC0-∞为(3 757±785) μg·h·L-1;V/F为(66.15±20.29) L;CL/F为(27.85±6.66) L·h-1,Cssmin为(105.4±57.17) μg·L-1;Cav为(450.9±91.2) μg·L-1;DF为(2.33±0.47);观察蓄积比Ro为(0.870±0.131).结论 盐酸头孢卡品酯片在剂量为100~300 mg范围内呈线性药动学特征,口服盐酸头孢卡品酯片,每日3次,每次1Objective To assess the pharmacokinetics of single and multiple-dose of cefcapene pivoxil hydrochloridetablets in healthy Chinese subjects. Methods Thirty healthy subjects were divided into three groups (each group consisting of 5 males and 5 females) by arandomized blind design. Two groups were administered with 200 mg and 300 mg cefcapene pivoxilhydrochloride tablets, respectively for a single dose test of pharmacokinetics profile. The third group was enrolled for a multiple-dose study, in which patients received cefcapene pivoxil hydrochloride tablets at 100 mg three times daily for 4 days. Pharmacoki-netics profile was assessed by determining concentrations of cefcapene acid with a validated HPLC-MS/ MS method. The pharma-cokinetic parameters were calculated by DAS 2. 0 and analyzed by SPSS 17. 0. Results After a single dose of oral administra-tion,the main pharmacokinetic parameters for cefcapene acid at doses of 100,200 and 300 mg were as follow: tmax as (1. 42±0. 54),(1. 80±0. 59) and (2. 10±0. 81) h; t 1/2 as (1. 45±0. 17),(1. 60±0. 22) and (1. 44±0. 18) h; MRT0鄄12 h as (2. 75±0. 42),(2. 99±0. 33) and (3. 31±0. 57) h; Cmax as (1 419±384),(2 128±366) and (2 438±655) 滋g·L-1 ; AUC0鄄12 h as (4 369±1 078),(7 477±1 616) and (9 091±3 735) 滋g·h·L-1 ; AUC0鄄肄as (4 389±1 080),(7 528±1 640) and (9 146±3 749) 滋g·h·L-1 ; V / F as (52. 13±21. 81),(63. 60±14. 78) and (76. 06±23. 29) L; CL/ F as (24. 27±7. 06),(27. 61±5. 42) and (36. 49±10. 31) L·h-1 ,respectively. The main pharmacokinetic parameters for cefcapene acid at 100 mg from the amulti-dose study were that: tmax as (1. 90±0. 70) h, t1/2 as (1. 63±0. 16) h, MRT0-12 h as (2. 87±0. 52) h, Cssmax as (1 133±200) μg·L-1 , AUCss as (3 607±730) μg·h·L-1 , AUC0-12 h as (3 731±775) μg·h·L-1 , AUC0-∞ as (3 757±785)μg·h·L-1 , V / F as (66. 15±20. 29) L, CL/ F as (27. 85±6.
