Description

一种治疗新型冠状病毒肺炎的药物组合物及其制备方法和 用途
技术领域
本发明属于药物领域,具体涉及一种治疗新型冠状病毒肺炎的药物组合物及其制备方法和用途。
背景技术
新型冠状病毒肺炎,简称“新冠肺炎”, 是一类新型病毒肺炎,目前已成全球流行趋势,被列为全球突发的公共卫生事件。新型冠状病毒肺炎传染性极强,人群普遍易感。
目前针对新型冠状病毒肺炎,推荐使用的药物有洛匹那韦/利托那韦(成人200mg/50mg/粒,每次2粒,每日2次),或磷酸氯喹(18岁-65岁成人,体重大于50公斤者,每次500mg,每日2次;体重小于50公斤者,第一二天每次500mg,每日2次,第三日至第七天,每次500mg,每日1次),或阿比多尔(成人200mg,每日3次)。但是,这些药物治疗有效率低,死亡率高;而且副作用大,致使临床应用受限。
新型冠状病毒肺炎属于中医“疫病”、“瘟疫”范畴,而中医药防治疫病已有数千年的历史,且取得了很好的疗效,尤其是在2003年的SARS防治中,中医药再次发挥了巨大作用。 因此,亟需研究出一种能够有效治疗新型冠状病毒肺炎的中药组合物。
发明内容
本发明的目的在于提供一种治疗新型冠状病毒肺炎的药物组合物及其制备方法和用途。
本发明提供了一种药物组合物,所述药物组合物是由下述重量配比的原料药组成的:麻黄2~4份,杏仁3~5份,生石膏7~9份,炙甘草5~7份,地龙5~7份,北五味7~9份,制附片3~5份,生姜2~4份,白术7~9份,白芍9~11份,茯苓9~11份,人参2~4份,桃仁5~7份,红花5~7份,三棱5~7份,莪术5~7份,红景天9-11份。
进一步地,所述药物组合物是由下述重量配比的原料药组成的:麻黄3份,杏仁4份,生石膏8份,炙甘草6份,地龙6份,北五味8份,制附片4份,生姜3份,白术8份,白芍10份,茯苓10份,人参3份,桃仁6份,红花6份,三棱6份,莪术6份,红景天10份。
本发明还提供了一种治疗新型冠状病毒肺炎的药物,所述药物是以上述的药物组合物为活性成分,加上药学上可接受的辅料制成的制剂。
进一步地,所述制剂为口服剂。
进一步地,所述口服剂为滴丸剂、软胶囊剂、汤剂、口服液、颗粒剂、散剂或片剂。
本发明还提供了一种制备上述药物组合物的方法,所述方法包括以下步骤:按重量配比称取原料药,打粉,混合均匀,即得。
本发明还提供了另一种制备上述药物组合物的方法,所述方法包括以下步骤:
(1)取生石膏、制附片,煎制;
(2)将除生石膏、制附片之外的其余所有原料药在水中浸泡,然后将浸泡后的原料药和水加入步骤(1)所得体系中,加热煎煮,过滤;在滤渣中再次加入水,加热煎煮,过滤;合并滤液,浓缩或干燥,即得。
进一步地,步骤(1)中,所述煎制时间为20~40min,优选为30min。
进一步地,步骤(2)中,所述浸泡时加入的水与麻黄的体积重量比为(400~600):1ml/g,优选为500:1 ml/g;所述再次加入的水与浸泡时加入的水的体积比为3:(2~3);所述浸泡时间为20~40min,优选为30min;所述加热煎煮的条件为:在水烧开的条件下煎煮20~30min。
本发明还提供了上述药物组合物在制备治疗新型冠状病毒肺炎的药物中的用途。
本发明中,“熟地”即熟地黄;“炙甘草”为甘草的炮制加工品,制法同中国药典中记载一致;“生石膏”为石膏生用; “北五味”为主产于东北的木兰科多年生落叶木质藤本植物五味子的成熟果实;“制附片”为白附子的炮制加工品,制法同中国药典中记载一致。
新型冠状病毒属于中医 “疫病”、“瘟疫”范畴,正如《素问·刺法论》中讲:“五疫之至,皆相染易,无问大小,病状相似。”“避其毒气,天牝从来。”因此,新型冠状病毒肺炎是病位在肺的疫病,温热浊毒、痰瘀互结为其病理因素。故本病的治疗首当清肺平踹,恢复肺的升降功能,化痰解毒、活血化瘀,清除病理产物,其次更重要的是恢复气血阴阳的平和。正如《黄帝内经》所言:“谨守病机,各司其属,...,令其条达,以致平和”。
本发明提供的药物组合物能够抑制新型冠状病毒肺炎普通型转重型/危重型的趋势,服用本发明的药物组合物后,重型/危重型患者治愈出院率高达79.7%,总治愈出院率高达80.1%。本发明的药物组合物还能够缩短患者发热病程,缩短患者住院天数,降低总体费用。本发明的药物组合物在制备治疗新型冠状病毒肺炎的药物中具有非常好的应用前景。
本发明药物组合物的制备工艺简单,适合工业生产。
