摘  要
目的:對丹參酮ⅡA緩釋固體脂質(zhì)納米粒凝膠骨架片的制備方法、處方及其體外釋放進行研究,為丹參酮ⅡA新制劑的開發(fā)提供思路和方法。
方法: 采用正交設(shè)計實驗方法,以載藥量和包封率為指標(biāo)優(yōu)選丹參酮ⅡA固體脂質(zhì)納米粒的處方,并采取單因素方法考察吸附介質(zhì)(乳糖、蔗糖的甘露醇),HPMC類型(K4M,K15M和K100M)及其用量(4%,7%和10%),PEG類型(PEG-400 ,PEG-400和PEG-10000)對丹參酮ⅡA緩釋固體脂質(zhì)納米粒凝膠骨架片緩釋性能的影響。
結(jié)果:丹參酮ⅡA固體脂質(zhì)納米粒的最佳處方為:丹參酮ⅡA 60 mg、單硬脂酸甘油酯100 mg、PEG-4000 200 mg、吐溫-80 400 mg、硬脂酸 200 mg。體外釋放速度:PEG-4000>PEG-400>PEG-10000;甘露醇>蔗糖≈乳糖;HPMC類型K4M > K15M > K100M;HPMC K15M含量4% > 7% > 10%。丹參酮ⅡA緩釋固體脂質(zhì)納米粒凝膠骨架片在0.5h─11h的最佳擬合模型為零級模型。
結(jié)論:經(jīng)優(yōu)選處方后,丹參酮ⅡA緩釋固體脂質(zhì)納米粒凝膠骨架片的載藥量和包封率顯著性提高,其體外釋放符合緩釋制劑藥物釋放設(shè)計要求。

A study on the sustained release Solid lipid nanoparticles hydrophilic matrix tablets of TanshinoneⅡA
Abstract
Objectives: Study on the preparation, formula and in-vitro release behavior of solid lipid nanoparticles hydrophilic matrix tablets of TanshinoneⅡA, which will provide some useful data for the development of the new dosage form of TanshinoneⅡA.
Methods: The formula of the solid nanoparticles has been studied by using orthogonal design with the entrapment efficiency and the percentage of drug loading as the index. The formula of the solid nanoparticles hydrophilic matrix tablet has been studied on the drug release behavior by using the single factor exploration method. It included the influence of the type and amount of the HPMC (K4M, K15M and K100M), the molecular weight of PEG (400, 4000 and 10000) and absorptive agent (Mannitol, sucrose and lactose).
Results: The best formula of the solid nanoparticle was tanshinone ⅡA 60 mg, glyceryl monostearate 100 mg, PEG4000 200 mg, Tween 80 400 mg and stearic acid 200 mg. The drug release rate of drug from the hydrophilic matrix tablet altered with the alteration of PEG, absorptive agent and the type and weight percentage of HPMC in the tablet. The drug release rates followed the following order: PEG-4000 > PEG-400 > PEG-10000, Mannitol > sucrose ≈ lactose,K4M > K15M > K100M,4% > 7% > 10% (K15M). Drug released from the tablet is following Zero-order mold between 0.5~11h.
Conclusion: Tanshinone ⅡA solid nanoparcles of the best formula owns good drug loading percentage and entrapment efficiency. Drug can be continuously released from the solid nanoparcles hydrophilic matrix tablet for a long time.
