摘要

制备了基于脂质包裹中空介孔二氧化硅纳米粒的姜黄素递药系统 (CUR-HMSN@lip),对其处方工艺参数进行优化, 并考察了在大鼠体内的药动学行为。采用 TEM、PXRD、ζ 电位和热重分析法对 CUR-HMSN@lip 进行表征,结果说明负载 姜黄素的中空介孔二氧化硅纳米粒 (CUR-HMSN) 成功被磷脂包裹。口服给予大鼠 CUR-HMSN@lip 后,tmax 为 (1.83±0.41)h, AUClast 为 (570.82±48.07)h·ng·mL–1 ,MRTlast 为 (5.68±1.21)h;与 CUR-HMSN 处理组相比,CUR-HMSN@lip 处理组的药 - 时曲线未出现双峰现象;CUR-HMSN@lip 的相对生物利用度为 203.8%。该研究表明,CUR-HMSN@lip 递药系统能提高姜 黄素的生物利用度,改善 CUR-HMSN 的突释现象。

Abstract

A drug delivery system of lipid-coated hollow mesoporous silica nanoparticles for curcumin (CUR-HMSN@lip) was constructed. Its formulation and process parameters were optimized, and its pharmacokinetic behavior in rats was investigated. The obtained CUR-HMSN@lip was characterized by TEM, PXRD, ζ potential, and thermogravimetric analyses, and the results indicated that the curcumin-loaded hollow mesoporous silica nanoparticles (CUR-HMSN) were successfully encapsulated by phospholipids. After orally administered of CUR-HMSN@lip to rats, the pharmacokinetic parameters of curcumin were determined and calculated. The results were as follows: tmax was (1.83±0.41)h, AUClast was (570.82±48.07)h·ng·mL–1 , and MRTlast was (5.68±1.21)h. Compared with the CUR-HMSN treatment group, the plasma concentration-time curve of the CUR-HMSN@lip treatment group did not show a double peak phenomenon. The relative bioavailability of CUR-HMSN@lip was 203.8% . It was concluded that the CUR-HMSN@lip delivery system increased the bioavailability of curcumin and improved the burst release of CUR-HMSN.
