Description
技术领域
本发明涉及中药技术领域,尤其涉及一种治疗冠心病心绞痛的药物及其制备方法和用途,具体涉及一种治疗冠心病心绞痛的内服纯中药胶囊剂及其制备方法,特别是一种用于气阴两虚、心血淤阻所致的胸痹心痛,胸闷、胸部刺痛或隐痛、心悸气短、倦怠懒言、头晕目眩、面色少华等症,冠心病心绞痛见上述证候者。
背景技术
随着老龄化进程的加速,疾病谱的改变,我国冠心病的患病率和死亡率正在呈快速上升趋势,成为严重危害人民健康的主要慢性非传染性疾病。
冠心病全称冠状动脉粥样硬化性心脏病,冠心病心绞痛是在冠状动脉血管发生动脉粥样硬化病变而引起血管腔狭窄或阻塞,冠状动脉供血不足、造成心肌急性、短暂性缺血、缺氧或坏死所引起的临床综合症。中医称冠心病心绞痛为胸痹,胸痹一证早在《内经》已有记述,《灵枢·五邪》篇曾指出:“邪在心,则病心痛”,属于中医学“胸痹”、“心痛”范畴。
目前西医治疗本病的方法主要分为药物治疗、介入治疗和外科治疗。药物治疗如扩冠、抗凝、抗血小板、调脂等。对重度不稳定型心绞痛一般能迅速控制病情,防止急性心肌梗死的发生。对药物治疗不能控制病情或容易发生冠心病突发事件的患者,介入治疗和冠脉搭桥术为其提供了新手段。但药物治疗有耐药、易复发、远期效果较差之弊。介入治疗和冠脉搭桥术存在技术要求高,费用昂贵等问题。外科治疗如冠状动脉搭桥术则存在着创伤大、康复慢等缺点和低心排综合征等术后并发症。激光心肌血管重建术,远期效果亦不确切。而中医中药治疗本病具有广泛的适应性及很大的可挖掘潜力,其优势在于辩证论治,整体调节注重气血的关系,调理阴阳,使之建立新的平衡为治疗目的。
综上所述,西医学以辨病为主,重视局部的器官和功能变化,借用精密仪器和多种先进手段,能揭示病变的具体部位及性质,诊断明确。辨证论治是中医学的特点,通过四诊合参,辨清病因、病位、病机以及邪正的关系。在防治冠心病心绞痛方面,中西医结合可以发挥其协同作用,标本兼治,以期进一步提高临床疗效,解除患者病痛。
发明内容
本发明是基于针对冠心病心绞痛的患病率和死亡率正在呈快速上升趋势,提供一种安全性高、副作用小,适合应用于轻、中度冠心病心绞痛,效果显著的药物及其制备方法。
本发明采用如下技术方案:
本发明的治疗冠心病心绞痛的药物包括以下重量份的原料:红景天1000-1500份、冬虫夏草65-95份、手参250-375份。
本发明的治疗冠心病心绞痛的药物还包括辅料,辅料含量为5-8份,所述的辅料为淀粉、糊精、羟丙纤维素中的任意一种。
作为优选的技术方案之一:本发明的治疗冠心病心绞痛的药物是由下列重量份的原料组成:红景天1000份、冬虫夏草65份、手参250份、辅料5份。
作为优选的技术方案之二:本发明的治疗冠心病心绞痛的药物是由下列重量份的原料组成:红景天1500份、冬虫夏草95份、手参375份、辅料8份。
作为优选的技术方案之三:本发明的治疗冠心病心绞痛的药物是由下列重量份的原料组成:红景天1312份、冬虫夏草82份、手参328份;、辅料7份。
本发明的治疗冠心病心绞痛的药物的剂型为片剂、胶囊剂、汤剂、丸剂、滴丸剂、颗粒剂、注射剂或口服液,优选的剂型为胶囊剂。
制备本发明的治疗冠心病心绞痛的中药胶囊剂的方法的具体步骤如下:
(1)按配比称取各种经除杂质的净药材原料,备用;
(2)冬虫夏草净药材在50-60℃环境下烘干,置洁净粉碎机中,进行粉碎操作,使粉末≥100目(细粉),进行灭菌处理后,密闭保存,备用;
(3)手参净药材在50-60℃环境下烘干,置洁净粉碎机中,进行粉碎操作,使粉碎成粗粉,置洁净回流提取罐内,用80%乙醇回流提取二次,每次1小时,滤过,药渣弃去,滤液合并密闭置阴凉处,备用;
