摘要: |
针对连翘酯苷稳定性较差,限制了药物制剂制备及临床应用的问题,采用环糊精包合技术研制连翘酯苷注射剂,利用研磨法制备连翘酯苷-羟丙基-β-环糊精包合物。表征分析表明包合物光谱和熔点发生变化,对光稳定性和热加速实验稳定性明显增加。高效液相色谱分析鸡静脉注射给药血药浓度,表明连翘酯苷包合物与连翘酯苷药物动力学差异较小,血液中包合态药物能较快发生脱包合作用。 |

Preparation of Forsythiaside-Hydroxypropyl-β-Cyclodextrin Inclusion Complex and Its Character |
|
(Beijing University of Agriculture) |
Abstract: |
To overcome the chemical unstablity of forsythiaside, the forsythiaside-hydroxypropyl-β-cyclodextrin inclusion complex was prepared by triturating. The inclusion complex was confirmed by the change of UV spectrum and melt temperature point. The inclusion complex has a higher stability to UV light and temperature than forythiaside itself. The inclusion complex has little effect on pharmacokinetics after injection to chickens vein. |
Key words: forsythiaside hydroxypropyl-β-cyclodextrin inclusion complex stability |
