摘 要:目的考察赖诺普利对盐酸马尼地平在大鼠体内药动学行为的影响。方法将大鼠随机分为单用盐酸马尼地平0.9 mg·kg^-1组和联用盐酸马尼地平0.9 mg·kg^-1+赖诺普利0.9 mg·kg^-1组,于灌胃给药后0-12.0 h内取静脉血,采用LC-MS/MS法测定血浆中盐酸马尼地平的质量浓度,以DAS 2.0计算药动学参数,SPSS 17.0进行统计分析。结果单用组与联用组盐酸马尼地平的药动学参数结果为:ρmax分别为(144.6±24.39)μg·L^-1和(150.2±24.63)μg·L^-1,AUC0-t分别为(489.4±190.5)μg·h·L^-1和(573.3±196.4)μg·h·L^-1,AUC0-∞分别为(566.7±233.4)μg·h·L^-1和(666.4±283.0)μg·h·L^-1,tmax分别为(0.8±0.21)h和(1.05±0.57)h,Vz/F分别为(1.84±0.82)L·kg^-1和(1.56±0.65)L·kg^-1,Cl/F分别为(7.90±3.67)L·h^-1·kg^-1和(6.28±1.69)L·h^-1·kg^-1。两组tmax、AUC0-t、Cl/F、ρmax、AUC0-∞、Vz/F和Cl/F均无显著性差异(P〉0.05)。结论赖诺普利对盐酸马尼地平在大鼠体内药动学行为无影响,提示临床联合给药无需调整马尼地平给药剂量及时间间隔。Objective To investigate the effect of lisinopril on pharmacokinetics of manidipine in rats plasma. Methods Rats were randomly divided into single drug group ( manidipine 0. 9 mg·kg^-1, i. g. ) and drug combination group ( manidipine 0. 9 mg·kg^-1 + lisinopril 0. 9 mg·kg^-1, i. g. ). The blood samples were collected within 0 - 12. 0 h after oral administration. The plasma concentrations of manidipine were determined by LC-MS/MS. Pharmacokinetic parameters were calculated with DAS 2. 0 software, and statistically analyzed with SPSS 17.0 software. Results The main pharmacokinetic parameters of 2 groups were as follows: Pmax = ( 144.6 ±24. 39 ) μg·L^-1 vs. ( 150. 2 ± 24.63 )μg·L^-1 , AUC0-t (489.4 ± 190. 5 ) p.g·h·L^-1 vs. (573.3±196. 4 ) mg·h. L^-1, AUC0-∞ = ( 566.7± 233.4 ) μg·h·L^-1 vs. (666.4±283.0)μg·h·L^-1 ,tmax = (0. 8 ±0. 21)h vs. (1.05±0. 57)h,Vz/F = (1.84±0. 82)L·kg^-1 vs. ( 1.56±0. 65 ) L. kg^-1, Cl/F = (7.90±3.67 ) L·h^-1·kg^-1 vs. ( 6.28±1.69 ) L·h^-1. kg^-1. No significant difference( P 〉 0.05 ) in the pharmacokinetic parameters of tmax, AUC0-t, Cl/F,Pmax, AUC0-∞, Vz/F, Cl/F were founded. Conclusions No significant effect of lisinopril on pharmacokinetics of manidipine in rats plasma, prompting that administration without dose adjustment manidipine and time interval in clinical.
