摘要:
Objective To evaluate the pharmacokinetic changes of Picika oral solution in healthy subjects after single dose.Methods This study taken random , three cross experiment design , 12 subjects were randomly divided into 6 groups, each group was 2 cases, then they were respec-tively given single oral doseof Picika oral solution (60, 90, 120 mL) in each cycle.Before and after administration , biological samples were col-lected for detection of blood drug concentration and urine drug concentra-tion, furthermore, calculation of blood and urine drug pharmacokinetic parameters.Results After single oral dose of 60, 90, 120 mL Picika oral solution, the main pharmacokinetic parameters of plasma CKL -A03, Cmax were (3.08 ±0.92), (3.63 ±0.75), (4.29 ±1.00)μg· L-1, tmax were (57.50 ±17.90 ), (52.50 ±20.73 ), (56.25 ±19.32 ) min, t1/2 were (197.51 ±106.35 ), (233.86 ±196.75 ), (141.34 ±65.16 ) min, AUC0-t were ( 383.28 ± 86.42 ) , ( 479.00 ± 136.25 ) , (540.59 ±102.87)μg · L-1 · min, AUC0-∞ were (710.06 ±233.03 ), (916.59 ±378.62 ), (782.65 ±130.40 )μg· L-1 · min, respectively. The main pharmacokinetic parameters of urine CKL -A03, t1/2 were (1.29 ±0.33), (1.23 ±0.20), (1.11 ±0.11) h, total urine discharge rates were (0.28 ±0.22)%, (0.20 ±0.11)%, (0.18 ±0.09)%, urine discharge amount were (74486.02 ±57923.42 ), (80015.14 ±43379.01 ), (93017.33 ±46658.61 ) mg.Conclusion The maximum oral absorption amount of Picika oral solution is possible 90 mL.And there is no apparent proportional relationship between the total urine discharge rate , urine discharge amount and the increased doses.%目的:评价谱圣康口服液单次给药在健康受试者体内的药代动力学变化。方法用随机、三交叉试验设计。将12例受试者随机分为6组,每组2例,分别于3个周期口服谱圣康口服液60,90,120 mL各1次,洗脱期为1周。给药前后按时间点采集生物样本以检测血药浓度和尿药浓度,并计算血药及尿药的主要药代动力学参数。结果单次口服谱圣康口服液60,90,120 mL 后,血浆中CKL-A03的主要药代动力学参数:Cmax分别为(3.08±0.92),(3.63±0.75),(4.29±1.00)μg · L-1;tmax 分别为(57.50±17.90),(52.50±20.73),(56.25±19.32)min;t1/2分别为(197.51±106.35),(233.86±196.75),(141.34±65.16) min;AUC0-t分别为(383.28±86.42),(479.00±136.25),(540.59±102.87)μg · L-1· min;AUC0-∞分别为(710.06±233.03),(916.59±378.62),(782.65±130.40)μg· L-1· min。尿液中CKL-A03的主要药代动力学参数:t1/2分别为(1.29±0.33),(1.23±0.20),(1.11±0.11)h;总尿排率分别为(0.28±0.22)%,(0.20±0.11)%,(0.18±0.09)%;尿排总量分别为(74486.02±57923.42),(80015.14±43379.01),(93017.33±46658.61) mg。结论谱圣康口服液最大吸收量可能为90 mL,且随剂量增加,总尿排率与尿排总量变化无明显比例关系。
