摘要: 目的: 比较研究BAPTA-AM脂质体注射液在大鼠和Beagle犬体内的药动学过程。方法: 通过LC-MS/MS方法测定大鼠、Beagle犬血浆中BAPTA-AM的浓度,采用非房室模型计算BAPTA-AM注射液在大鼠、Beagle犬体内的药动学参数。结果: 大鼠尾静脉注射 1.5、3.0、6.0 mg/kg BAPTA-AM脂质体注射液后,体内消除半衰期分别为(255±140)、(290±260)、(376±257)min,AUC0-∞分别为(831±251)、(1467±528)、(3650±1664) μg·L-1·min;Beagle犬静脉注射 0.5、1.0、2.0 mg/kg BAPTA-AM脂质体注射液后,体内3个剂量的消除半衰期分别为(362±305)、(347±278)、(432±292) min,AUC0-∞分别为(400±118)、(569±139)、(1185±640) μg·L-1·min。结论: 静脉注射给药后,BAPTA-AM脂质体注射液在大鼠和Beagle犬体内代谢较快,分布较广,在两种动物内的药动学过程无统计学差异。

Abstract: AIM: To compare the pharmacokinetics of BAPTA-AM liposome injection in rats and Beagle dogs. METHODS: The concentration of BAPTA-AM in plasma was quantified by LC-MS/MS after intravenous injection. The pharmacokinetic parameters were calculated by the non-compartment model. RESULTS: The elimination half-life in rats after intravenous injection 1.5, 3.0 and 6.0 mg/kg BAPTA-AM liposome were (255±140), (290±260)and (376±257)min respectively, and the AUC0-∞ were(831±251), (1467±528)and(3650±1664) μg·L-1·min, respectively. The elimination half-life in dogs after intravenous injection 0.5, 1.0 and 2.0 mg/kg BAPTA-AM liposome were (362±305), (347±278)and (432±292)min respectively, and the AUC0-∞ were (400±118), (569±139)and (1185±640) μg·L-1·min, respectively. CONCLUSION: After intravenous injection, BAPTA-AM liposome is metabolized rapidly and distributed abroad in rat and Beagle dog. There is no difference in the pharmacokinetic between rats and dogs.
