摘  要:目的:研究复方去甲斑蝥素(NECT)胃内滞留漂浮型缓释片在犬体内的药动学过程。方法:采用高效液相色谱法,测定Beagle犬血浆药物浓度。双周期交叉实验设计,8只健康Beagle犬分别服用漂浮型缓释片或普通片,检查药动学参数。结果:复方NECT胃内漂浮型缓释片与NECT普通片在犬体内的药动学规律均符合二室模型,tmax分别为(3.01±0.02)、(2.02±0.03)h,Cmax分别为(58.3±4.4)、(56.6±3.90)μg·mL,AUC0~24分别为(536.4±33.8)、(232.50±10.63)μg·h·L^-1,MRT分别为(8.3±0.4)、(3.3±0.05)h,复方NECT胃内漂浮型缓释片的相对生物利用度为230.71%。结论:复方NECT胃内漂浮型缓释片可以提高NECT的生物利用度。OBJECTIVE: To study the pharmacokinetic process of Compound norcantharidin sustained release tablets remaining floating in stomach in dogs. METHODS: Plasma drug concentration was determined by HPLC. By twoperiod crossover experiment design, 8 healthy beagle dogs were assigned to receive Compound norcantharidin sustained release tablets remaining- floating in stomach or common norcantharidin tablets, with pharmacokinetic parameters determined. RESULTS: The pharmacokinetics of both Compound norcantharidin remaining- floating sustained release tablets and common norcantharidin tablets fitted two- compartment model, their pharmacokinetic parameters were stated as follows: tmax: (3.01 ± 0.02) h vs.(2.02±0.03) h; Cmax: (58.3±4.4) μg·mL^-1 vs.(56.6±3.90) μg·mL^- 1 AUC0-24: (536.4±33.8) μg· h· L^-1 vs. (232.50 ± 10.63) μg · h · L^- 1; MRT : (8.3 ± 0.4) h vs. (3.3 ± 0.05) h. The relative bioavailability of Compound norcantharidin remaining- floating sustained release tablets was 230.71%. CONCLUSION: The Remaining- floating (in stomach) property of Compound norcantharidin sustained release tablets contributed to higher bioavailability as compared with the common tablets of norcantharidin.
