Description

一种缓解便秘的中药纳米饮片及其制备方法
技术领域
本发明涉及中药纳米饮片技术领域,尤其涉及一种缓解便秘的中药纳米饮片及其制备方法。
背景技术
近年来现代中药如滴丸、注射剂、透皮吸收剂等相继出现,但与化学药等相比,现代中药剂型数量仍相对较少、品种较为单一。纳米中药粒径小、选择吸附性强,有更强的穿透力。利用纳米技术和纳米材料无疑是丰富中药剂型,促进中药现代化发展的有效途径。纳米技术对中药领域的影响是多方面的,涉及中药制剂、中药化学等众多学科。纳米技术在中药研究中的应用,提高了药物的制剂水平,同时也为纳米中药的研制提供了一定的基础,这将给中医药带来革命性的发展。采用纳米技术加工中药,使药物颗粒达到超细粉末的水平,比表面积和黏附性显著增大,药物在胃肠道里的溶解度明显增加,与肠壁接触时间延长,从而增加药物的生物利用度。何军等采用大鼠对不同粒径的水飞蓟素固体脂质纳米粒口服吸收进行了比较研究,发现150 nm固体脂质纳米粒的生物利用度明显高于粒径为500 nm和1000 nm两种制剂,粒径大小对水飞蓟素的口服吸收有显著影响。采用纳米技术加工中药,可使植物的细胞壁破碎,易于有效成分的渗出。高压均质法是利用高压均质机造成的空化和气穴效应,将微粉化的药物颗粒进一步粉碎为纳米尺寸的粒子,同时降低药物粒径的多分散性。该法适用范围广且制备过程简单,无需使用有机试剂,适用于既难溶于水也难溶于油的药物,而且工艺的重现性较好,易于大规模工业化生产,从而被认为是纳米混悬剂最理想的制备方法。为了得到稳定的纳米混悬剂,避免纳米粒子发生凝聚,在制备过程中需要加入一些表面活性剂。
然而传统中药纳米化后,其理化特性、生物活性等方面有可能发生改变,原有药物功效有可能增强,也有可能减弱或消失,甚至出现新的不良反应。中药成分极其复杂,不同成分作用的部位、靶点不同,产生的作用机制不同,制备的纳米粒也应不同,因此纳米中药的研究尚待突破。郭静静在《基于纳米混悬技术的中药难溶性有效成分给药系统的研究》中将纳米混悬技术应用到中药难溶性有效成分给药系统的研宄,拟选中药波棱瓜子的难溶性有效成分为模型药,采用先进的纳米混悬技术,通过工艺蹄选、处方优化等制备纳米混悬剂,并对其进行体外理化性质和体内药代动力学评价,为其它中药难溶性有效成分给药系统的研宄提供依据,以改善中药难溶性有效成分的体外溶出度和体内生物利用度。
