Description
技术领域
本发明涉及一种中药外用制剂,具体涉及一种具有抗肿瘤作用的外用制剂及其制备方法。
背景技术
中国恶性肿瘤死亡抽样回顾调查显示:在恶性肿瘤死亡率中,前三位的恶性肿瘤类型依次为:肺癌、肝癌和胃癌。流行病学研究提示,我国不仅肿瘤死亡率呈明显上升趋势,而且兼有发展中国家和发达国家高发谱并存的特点。究其原因主要有四点:第一个原因是人口的老年化,第二个原因是工业化发展,第三个原因是农村的城市化,第四个原因就是人们不良的生活习惯。
目前市场上广泛用于恶性肿瘤治疗的药物多是化学药品和生物制品,这些一线肿瘤用药不仅价格昂贵,而且对人体均存在不同程度的不良反应。中医和中药是我们中华民族的国粹,是中华民族几千年与疾患斗争的历史,更是人类的医学思想和药物的宝库,努力开发具有我国独立自主知识产权的,疗效确切的抗肿瘤新药一直是我国医药学者们孜孜不倦努力研究的重要方向。现有的抗肿瘤药物大多是采用口服的方式给药,但是这种服用方式经过肝脏的代谢,不仅对肝脏产生较大的毒副作用,且由于首关效应导致活性成分不能发挥抗肿瘤的疗效,降低抗肿瘤的效果。
因此,开发出具有抗肿瘤效果的外用制剂,不仅可防止肝脏代谢,提高活性成分抗肿瘤效果,并且可降低对肝脏等器官的毒副作用,具有重要的意义。
发明内容
发明目的:本发明的目的是解决现有技术的不足,提供一种配比科学合理,疗效确切,临床使用安全,不良反应更低,吸收好,具有明显的抗肿瘤作用的外用制剂。
技术方案:为了实现以上目的,本发明采取的技术方案为:
一种具有抗肿瘤作用的外用制剂,它由西洋参40~50份、蟾酥0.25~0.30份、天门冬140~160份、土贝母180~200份、倒卵叶五加550~650份、猕猴桃根800~1000份、沙棘果300~330份和佛手140~160份的提取物和药学上可接受的载体制备成外用制剂。
作为优选方案,以上所述的具有抗肿瘤作用的外用制剂,它由西洋参50g、蟾酥0.25g、天冬167g、土贝母200g、倒卵叶五加599g、猕猴桃根1000g、沙棘果333g、佛手167g的提取物和药学上可接受的载体制备成外用制剂。
作为优选方案,以上所述的具有抗肿瘤作用的外用制剂,所述的外用制剂为凝胶剂、软膏剂或栓剂。
作为优选方案,以上所述的具有抗肿瘤作用的外用制剂,所述的抗肿瘤作用为抗皮肤癌、肠癌、胃癌、肺癌、皮肤癌、肝癌或宫颈癌。
本发明所述的中药组合物的制备方法,包括以下步骤:
步骤1、取沙棘果,干燥,粉碎,过40目筛;
步骤2、取西洋参加6至10倍量的乙醇超声提取3至4次,每次1至1.5小时,合并提取液,静置,滤过;
步骤3、取佛手、天冬、土贝母和倒卵叶五加,加6至12倍量的乙醇加回流提取1至3次,每次1至3小时,合并提取液,滤过;上大孔吸附树脂柱,先用水洗脱,然后依次用30%乙醇、50%乙醇和60%乙醇洗脱,收集50%乙醇洗脱液,浓缩;
步骤4、取猕猴桃根,先浸泡30至40分钟,然后加水煎煮2至3次,每次1至2小时,合并煎液,滤过,浓缩;
步骤5、取蟾酥,干燥,粉碎过80目筛;
步骤6、取步骤1至步骤5制备得到的各药材提取物和粉末混合均匀,加入药学上可接受的载体制备成凝胶剂、软膏剂或栓剂。
作为优选方案,以上所述的具有抗肿瘤作用的外用制剂的制备方法,所述的软膏剂由:聚丙烯酸钠800~1000份、交联聚维酮600~800份、聚乙烯吡咯烷酮350~500份、甘羟铝25~50份、依地酸二钠6~10份、甘油4000~5000份、L-酒石酸35~50份的重量分数原料制成。
有益效果:本发明提供的具有抗肿瘤作用的外用制剂及其制备方法和现有技术相比具有以下优点:
本发明根据中医药理论,采用辨证论治的理论进行中药组方筛选,饼通过大量实验筛选制备得到外用制剂。本发明提供的外用制剂,吸收率高,可避免首关效应,促进有效成分直达治疗靶点,疗效好,且可大大降低对肝脏等器官的不良反应,安全性更高。
具体实施方式
下面结合具体实施例进一步阐明本发明,应理解这些实施例仅用于说明本发明而不用于限制本发明的范围,在阅读了本发明之后,本领域技术人员对本发明的各种等价形式的修改均落于本申请所附权利要求所限定的范围。
