【摘要】 目的:总结近年壳聚糖及衍生物在药物制剂中的应用现状。方法:由作者应用计算机检索维普数据库,检索时限1999-01/2010-10。检索关键词:壳聚糖,缓释,药物,应用。纳入有关壳聚糖的制备方法及其在药物制剂中应用的文章,排除较陈旧文献。共保留相关文献20篇进入结果分析。结果:壳聚糖具有良好的生物相容性、可生物降解性、无毒性和易成膜性,在国内外药学领域,壳聚糖应用于缓释、控释制剂的研究颇受人们关注。利用壳聚糖特有的物理化学性质,如遇酸膨胀形成凝胶、有良好成膜性及促进多肽类、蛋白质药物的透黏膜吸收等特点,人们一般将壳聚糖以片剂、成膜材料及微球、微囊等形式,作为缓释、控释制剂的骨架材料。结论:用壳聚糖所开发的缓控释制剂,均衡了释药速率,减少了药物对正常组织细胞的毒副作用。更多还原

【Abstract】 OBJECTIVE:To summarize the application status of chitosan and derivant in pharmaceutical preparation.METHODS:VIP database was retrieved by computer,the time was limited to 1999-01/2010-10.The index words were "chitosan,release,drug,application" in Chinese.Articles about the application status of chitosan and derivant in pharmaceutical preparation were included,outdated literatures were excluded.Totally 20 documents were involved for analysis.RESULTS:Chitosan has a good biocompatibility,biodegradation,avirulent,and easily film-forming.In the field of pharmacy at home and abroad,chitosan was used to the research of release and controlled release preparation attracted people’s attention.The unique physical and chemical properties of chitosan,such as chitosan encounter acid expansion form a gel,have good film-forming and promote the polypeptide,transdermal absorption of protein drugs.Chitosan generally in the form of tablet,film-former,microsphere and microcapsule served as skeleton materials of release and controlled release preparation.CONCLUSION:Controlled release preparations developed by chitosan can balance the drug release rate and reduce drug side effects of normal tissue cells.更多还原
