摘要:以两步乳匀法制备氟比洛芬酯(FA)脂微球,采用动态光散射法、超速离心法测得FA脂微球粒径为(168.6±9.3)nm,Zeta电位为(-34.8±1.4)mV,包封率为(99.4±0.9)%;用高效液相色谱法检测兔体内FA代谢产物氟比洛芬(FP),FA脂微球静脉给药后,FP主要药物动力学参数分别如下:t1/2β为(0.83±0.13)h,AUC0→24h为(16.10±1.56)μg·h/mL,CL为(0.41±0.02)L/(h·kg)。制得的FA脂微球包封率高,稳定性好,在兔体内的FP药物动力学过程符合二室模型。
Flurbiprofen axetil (FA) loaded lipid microspheres (LM) were prepared by two-step emulsification method. Their mean size was (168.6 ± 9.3) nm as determined by dynamic light scattering and uhracentrifugation. The zeta potential was (--34. 8± 1. 4) mV, and entrapment efficiency was (99.4±0.9)%. A high-performance liquid chromatography (HPLC) method was established to detect flurbiprofen (FP) concentration of the FA loaded LM in rabbits after intravenous injection. Pharmacokinetic parameters were t1/2β: (0.83 ± 0.13) h, AUC0-24h:( 16. 10 ± 1.56) μg·h/mL, CL: (0.41± 0.02) L/(h ·kg), respectively. The obtained LM showed high entrapment efficiency of FA with high stability. The plasma concentration of FP showed that the pharmacokinetics of FA loaded LM was well fitted by two-compartments model.
