摘 要:采用单剂量随机交叉实验设计,评价8只比格犬口服受试或参比醋酸艾司利卡西平片的相对生物利用度。用UPLC-MS/MS法测定血浆中的艾司利卡西林浓度,艾司利卡西平的线性范围为:1.0~1000.0ng/ml;定量下限可达1.0ng/ml;受试和参比制剂的主要药动学参数分别为:T_(max)(1.72±1.2)和(1.50±0.9)h;C_(max)(31300±14104)和(40088±18156)ng/ml,AUC_(0-t)(133121±60209)和(146 926±61 557)ng·h/ml,AUC_(0-∞)(133 171±60 207)和(147 028±615 93)ng·h/ml,t_(1/2)(5.84±2.0)和(5.80±1.1)h。受试制剂艾司利卡西平的相对生物利用度为(106.1±102.6)%。结果显示:两制剂平均药动学参数无统计学差异。The relative bioavailability of eslicarbazepine acetate tablets in eight Beagle dogs was evaluated by a randomized single-dose cross-over design.The concentration of eslicarbazepine in plasma was determined by UPLC-MS/MS.The calibration curve for eslicarbazepine was linear in the range of 1.0~1 000.0 ng/ml with the lower limit of quantification 1.0ng/ml.The main pharmacokinetic parameters for test and reference preparations were as follows:T_(max)(1.72±1.2) and(1.50±0.9)h;C_(max)(31 300±14 104) and(40 088±18 156) ng/ml,AUC_(0-t)(133 121±60 209) and(146 926±61 557) ng·h/ml,AUC_(0-∞)(133 171±60 207) and(147 028±61593) ng-h/ml,t_(1/2)(5.84±2.0) and(5.80±1.1) h.The relative bioavailability of eslicarbazepine acetate tablets for test preparations was(106.1±102.6)%.The results showed that these two preparations had no significant difference in the average pharmacokinetic parameters.
