Description

一种用于护肝的药物组合物及其制备方法
技术领域
本发明涉及一种医用配制品,具体涉及以中药为原料制备的中成药。
背景技术
慢性乙型肝炎是我国常见病、多发病,危害各年龄层人群的健康,肝病时肝功能有不同程度的损害,肝脏解毒、排泄功能及贮备和再生能力降低,肝血流量减少,各种进入肝脏的药物使代谢负荷加重,从而发生内环境紊乱,进而造成肝损伤,长期的肝损伤可以导致肝硬化甚至肝癌。
目前,临床上普遍采用干扰素治疗慢性乙肝,虽然使用范围广,但疗效却越来越令人失望,同时干扰素治疗乙肝有适应症,有明显不良反应,与我国的肝病特点不符;另外一个常用药拉米夫定在其应用初期,以抑制病毒迅速,乙肝病毒DNA转阴率高,不良反应较轻、较少,价格相对低廉等优点,得到医生和患者的青睐,随着治疗时间的延长,问题慢慢浮现出来;如诱导乙肝病毒的变异,先喜后忧的现实,较窄的适应证,有限的治疗效果,遥遥无期的疗程,停药后的“反弹”,并且可能使病情明显加重,甚至恶化。
我国是肝炎高发大国,现有各类型肝病患者已超过2亿,大多需要具有肝脏保护作用的药物,代医学对肝损伤的研究比较深入,已从多方面探讨了肝损伤的发生机制,并研制开发出多种保肝药物,但疗效尚难尽人意;中药有着多靶点、多环节综合作用的特点,在治疗肝损伤方面有独特的优势。
发明内容
本发明目的就是按照中医药理论科学组方,采用现代提取、制剂工艺研制出一种具有改善肝功能、降低转氨酶的药物。
本发明实现上述目的的技术方案为:
一种用于护肝的药物组合物,该药物组合物由有效成分和药学上可接受的辅料组成,其特征在于,所述的有效成分由以下重量份的原料药制成:女贞子1.5~2.5份,五味子0.5~1.5份,淫羊藿1~1.5份,虎杖2~3份,紫河车1~1.5份,刺五加1~2份,黄芪1~1.5份,丹皮1~2份,板蓝根1~2份,黄芩0.5~1.5份,桑寄生0.5~1.5份,柴胡0.5~1.5份。
上述药物组合物中有效成分由以下重量份的原料药制成:女贞子2份、五味子1份、淫羊藿1.3份、虎杖2.5份、紫河车1.3份、刺五加1.5份、黄芪1.3份、丹皮1.5份、板蓝根1.5份、黄芩1.1份、桑寄生1.1份、柴胡1份。
上述药物组合物由以下方法制成:取女贞子、五味子、虎杖和黄芩采用乙醇提取,回收乙醇后得浸膏A;取淫羊藿、刺五加、黄芪、板蓝根、桑寄生、柴胡、紫河车采用水煎煮提取,提取液浓缩成浸膏后,加入乙醇至醇浓度大于50%,滤除沉淀,上清液浓缩得浸膏B;丹皮采用水蒸汽蒸馏提取得到丹皮酚;将浸膏A和B混匀,加入药用淀粉和/或糊精干燥后与丹皮酚混匀粉碎,再采用常规工艺制成片剂或胶囊剂。
本发明所述的药物组合物,方中以桑寄生、淫羊藿为君,滋肾养肝;再以黄芪益气固本,女贞子、紫河车滋阴养血,五味子、刺五加养肝降酶,共为臣药;佐以虎杖、板蓝根、丹皮清热凉血解毒;醋柴胡疏肝解郁、引药入肝为使药。现代药理研究表明:板蓝根、虎杖、黄芩、柴胡对乙肝病毒有抑制作用;五味子、刺五加具有降低转氨酶作用;黄芪、女贞子、淫羊藿可以增强机体免疫功能。因此,不但中医传统理论与临床实践,抑或现代药理研究均表明本处方组方法度严谨,依据充分。
具体实施方式
药物制剂的制备:取女贞子20千克、五味子10千克、淫羊藿13千克、虎杖25千克、紫河车13千克、刺五加15千克、黄芪13千克、丹皮15千克、板蓝根15千克、黄芩11千克、桑寄生11千克、柴胡10千克。按照如下工艺,女贞子、五味子、虎杖、黄芩四味中药混合后采用乙醇提取两次,每次加70%乙醇6倍量回流提取1小时,回收乙醇后得浸膏A;淫羊藿、刺五加、黄芪、板蓝根、桑寄生、柴胡、紫河车7味中药,采用水煎煮提取两次,每次加水10倍量提取两次,提取液浓缩成相对密度约在1.20的浸膏后,加入乙醇至醇浓度为60%,滤除沉淀,上清液浓缩得浸膏B;丹皮采用水蒸汽蒸馏的方法提取得到丹皮酚;将浸膏A和B混匀,加入药用淀粉和/或糊精干燥后与丹皮酚混匀粉碎,装入胶囊,即得。
临床应用研究:慢性乙型肝炎诊断按1990年第6次全国肝病会议制定的慢性乙型肝炎诊断标准。120例分为治疗组80例,对照组40例。治疗组80例中男52例,女28例;年龄最小18岁,最大62岁,平均31.71±8.12岁;病程1-8年,平均3.31±2.53年。对照组40例中男25例,女15例;年龄最小19岁,最大63岁,平均3.25±7.93岁。病程1-9年,平均3.35±2.71年。根据卫生部1993年10月制定的《中药新药治疗病毒性肝炎的临床研究指导原则》作辨证分型。湿热薰蒸证:治疗组19例,对照组9例;瘀毒内结证:治疗组25例,对照组13例;气滞血瘀证:治疗组36例,对照组18例。以上两组资料经统计学处理无显著性差异(P>0.05)。
治疗方法治疗组用该方制剂口服,每次3粒,1日3次。对照组采用联苯双酯滴丸15mg,维生素C200mg,肝泰乐0.2g,每日3次口服。4周为一个疗程,可连续治疗2-3个疗程,治疗结束后作疗效评定。
疗效标准根据卫生部1993年10月制定《中药新药治疗病毒性肝炎(慢性肝炎)的临床研究指导原则》中的标准作疗效评定。
基本治愈:自觉症状消失;肝脾肿大稳定不变或缩小,无压痛及叩痛;肝功能检查正常;以上各项指标稳定1年以上者。
有效:主要症状消失,或基本消失;肝脾肿大稳定不变,且无明显压痛及叩痛;肝功能检查正常或原值下降50%以上,并持续3个月者。
无效:疗程结束后,SGPT不下降者。
治疗结果治疗组80例,基本治愈26例,显效28例,有效20例,无效6例,总有效率为92.5%。对照组40例,其中治愈7例,显效9例,有效9例,无效15例,总有效率为62.5%,两组临床疗效比较,有显著性意义(卡方检验P<0.01)。
不良反应:治疗前后对血常规、肝、肾功能检测未发现损害现象。
