摘  要:目的评价盐酸安妥沙星片在中国健康受试者空腹和餐后多剂给药的药代动力学。方法按随机、开放、多剂量(200,400,600 mg)空腹和餐后多次口服给药的方法进行设计。每个剂量组各有8名受试者(男4例、女4例)在空腹和餐后条件下连续7 d口服规定剂量的盐酸安妥沙星片。第1天和第7天给药后收集不同时间点的血、尿样本,用HPLC法测定浓度。结果3个剂量组空腹和餐后连续7 d口服盐酸安妥沙星片200,400,600 mg的主要药代动力学参数如下:第1天空腹口服的C_(max)分别为(2.23±0.38),(4.59±1.40),(5.03±0.77)mg·L^(-1),t_(1/2β)分别为(11.99±3.31),(10.97±5.33),(14.39±1.63)h,t_(max)分别为(1.37±0.78),(2.04±1.42),(2.90±2.02)h,AUC_(0-t)分别为(27.61±6.14),(51.77±22.09),(73.62±10.14)mg·L^(-1)·h,AUC0-∞分别为(38.28±13.49),(72.28±42.80),(108.91±13.26)mg·L^(-1)·h,V/F(92.84±12.98),(91.90±14.55),(116.28±22.62)L,CL/F(5.73±1.71),(7.67±4.65),(5.58±0.66)L·h^(-1);第1天餐后口服的C_(max)分别为(2.36±0.43),(4.11±1.53),(5.60±1.00)mg·L^(-1),t_(1/2β)分别为(14.37±4.34),(11.25±5.39),(15.53±2.94)h,t_(max)分别为(2.69±1.62),(2.40±1.50),(2.65±1.29)h,AUC_(0-t)分别为(33.69±4.00),(48.07±22.19),(78.01±17.18)mg·L^(-1)·h,AUC0-∞分别为(50.71±8.86),(67.37±41.98),(121.31.66±33.54)mg·L^(-1)·h,V/F分别为(81.04±16.35),(106.32±34.33),(114.08±20.00)L,CL/F分别为(4.07±0.82),(8.28±5.29),(5.23±1.18)L·h^(-1);第7天稳态后空腹口服的C_(max)分别为(3.69±1.39),(7.54±2.95),(8.50±0.93)mg·L^(-1),t_(1/2β)分别为(25.22±3.34),(19.56±12.47),(15.95±2.85)h,t_(max)分别为(1.64±1.29),(1.31±0.79),(1.60±1.07)h,AUC_(0-t)分别为(72.29±24.00),(142.96±67.20),(180.81±35.33)mg·L^(-1)·h,AUC0-∞分别为(75.90±25.46),(148.26±69.86),(183.30±35.11)mg·L^(-1)·h,V/F分别为(184.77±52.51),(119.22±53.92),(118.91±30.13)L,CL/F分别为(5.06±1.18),(4.75±1.72),(5.15±0.72)L·h^(-1);第7天稳态后餐后口服的C_(max)分别为(3.53±1.06),(6Objective To evaluate the pharmacokinetics of multiple dose of antofloxacin hydrochloride tablet under fast and food state in Chinese healthy subjects. Methods A randomized,open and multiple dose study was conducted. Three dose groups with 16 subjects per group were given the dose of 200,400 and 600 mg antofloxacin hydrochloride tablet,once daily for 7 days respectively. 8 subjects( 4 male and 4 female) were administrated under fast state and 8 subjects( 4 male and 4 female) under food state in each dose. The concentrations of antofloxacin in plasma and urine were determined by HPLC method. Results The main pharmacokinetics parameters of three dose( 200,400 and600 mg) under fast at first day were as follows: C_(max)were( 2. 23 ± 0. 38),( 4. 59 ± 1. 40),( 5. 03 ± 0. 77) mg·L^(-1),t_(1/2β)were( 11. 99 ± 3. 31),( 10. 97 ± 5. 33),( 14. 39 ± 1. 63) h,t_(max)were( 1. 37 ± 0. 78),( 2. 04 ± 1. 42),( 2. 90 ± 2. 02) h,AUC_(0-t)were( 27. 61 ± 6. 14),( 51. 77 ± 22. 09),( 73. 62 ± 10. 14) mg·L^(-1)·h,AUC0-∞were( 38. 28 ± 13. 49),( 72. 28 ± 42. 80),( 108. 91 ± 13. 26) mg · L^(-1)· h, V/F were( 92. 84 ± 12. 98),( 91. 90 ± 14. 55),( 116. 28 ± 22. 62) L,CL/F were( 5. 73 ± 1. 71),( 7. 67 ± 4. 65),( 5. 58 ± 0. 66) L·h^(-1),respectively; under food state at first day,C_(max)were( 2. 36 ± 0. 43),( 4. 11 ± 1. 53),( 5. 60 ± 1. 00) mg·L^(-1),t_(1/2β)were( 14. 37 ± 4. 34),( 11. 25 ± 5. 39),( 15. 53 ± 2. 94) h, t_(max)were( 2. 69 ± 1. 62),( 2. 40 ± 1. 50),( 2. 65 ± 1. 29) h,AUC_(0-t)were( 33. 69 ± 4. 00),( 48. 07 ± 22. 19),( 78. 01 ± 17. 18) mg·L^(-1)·h,AUC0-∞were( 50. 71 ± 8. 86),( 67. 37 ± 41. 98),( 121. 31. 66 ± 33. 54) mg · L^(-1)· h,V/F were( 81. 04 ± 16. 35),( 106. 32 ± 34. 33),( 114. 08 ± 20. 00) L,CL/F were( 4. 07 ± 0. 82),( 8. 28 ± 5. 29),
