Description

六味地黄滴丸的制备方法
技术领域
本发明属于中药领域,具体涉及一种六味地黄滴丸的制备方法。
背景技术
六味地黄滴丸由熟地黄、山茱萸、山药、泽泻、茯苓、牡丹皮六味中药材组成,源于宋代医学家钱乙的《小儿药证直诀》,是滋补肾阴的基础方剂,配伍组方上具有“三补三泻”的特点。 六味地黄滴丸是中医滋阴补肾的代表方剂,历经数百年医家的运用,其疗效确切,组方严谨合理,成为滋补肾阴的代表名方。滴丸采用固体分散技术,以无任何毒副作用的聚乙二醇为基质,以甲基硅油为冷却剂,制成滴丸,具有药物在胃肠道表面分布面积增大,可减少刺激性,提高生物利用度,不受胃排空因素影响,药物体内吸收均匀,个体差异小,有效成份高,是一般中成药的10~20倍,保证药物稳定性,掩盖不良味道,圆整度高,硬度高,载药量高、颗粒均匀等特点。但其在生产过程中,存在工艺不稳定,产品批间差异很大等问题。
超微粉碎技术目前在各个领域得到了广泛应用,但是在中药生产中应用还不多见。药材和浸膏通过无尘超微粉碎,可以大大提高有效成分的释放,可以提高有效成分的吸收,提高患者用药水平。大量研究表明,经过超微粉碎的药材或者浸膏,大约原药材1/2-1/3的服用量即可以达到普通粉碎的药材。而且安全性研究也表明,通过超微粉碎,用药的安全性没有任何降低。无尘超微粉碎还可以大大 减少粉碎损耗,避免环境污染。
发明内容
本发明为了解决现有技术存在的问题,采用水提醇沉、醇提等技术提取有效药用成分,提取液经浓缩、减压干燥后,进行超微粉碎。通过现代固体分散制剂技术滴制,显著提高浸膏粉收率、改善口感、减少有效成分损失,提高产品质量、提高药效。
本发明提供如下技术方案:
本发明提供一种六味地黄滴丸制备方法,该方法包括步骤1、将熟地黄1408份,牡丹皮528份,山药704份,山茱萸704份,泽泻528份和茯苓528份用乙醇提取两次,水沉,浓缩至相对密度为1.30的浸膏;
步骤2、将步骤1所得的浸膏减压干燥,用贝利微粉机将干浸膏进行超微粉碎,细度10~50um;
步骤3、将提取物采用固体分散技术,加入分散基质中,以甲基硅油为冷却剂,制成滴丸,所述的基质为PEG6000、甘油、水。
进一步的,上述制备方法中,所述的步骤(2)中的超微粉粹细度为10-25um。
进一步的,上述制备方法中,所述的步骤(3)中的提取物:PEG6000:甘油:水=1:1.55:0.1:0.2。
本发明有益效果
六味地黄滴丸具有更好的生物利用度、起效迅速,有利于患者服用。滴丸与六味地黄丸相比,具有以下优点:采用超微粉粹技术和固体分散制剂技术,有利于提高生物利用度,起效迅速,有利于患者服用;独特的固体分散释放基质,可以舌下含服,起效迅速。其中采用固体分散技术,以无任何毒副作用的聚乙二醇为基质,以甲基硅油为冷却剂,制成滴丸,具有药物在胃肠道表面分布面积增大,可减少刺激性,提高生物利用度,不受胃排空因素影响,药物体内吸收均匀,个体差异小,有效成份高,是一般中成药的10~20倍,保证药物稳定性,掩盖不良味道,圆整度高,硬度高,载药量高、颗粒均匀等特点。
