Description

一种治疗痛经的复方中药颗粒剂的研制
技术领域:
本发明涉及医药技术领域,确切的说是它是一种治疗原发性痛经的复方中药颗粒剂的制备方法。
背景技术:
总所周知,痛经是一种女性多发病,分为原发性痛经和继发性痛经,原发性痛经常见于年轻妇女,多项流行病学调查结果表明原发性痛经是目前妇科最常见的疾病之一,严重影响了女性的身心健康与工作质量。继发性痛经主要与子宫器质性病变有关,而原发性痛经的病因复杂,疼痛的发生不仅与子宫内膜前列腺素的分泌有关,也与神经、内分泌以及免疫遗传等因素有关。
而在痛经的治疗方面,西药主张止痛、镇静以及使用前列腺素抑制剂,虽然达到了一定疗效,但作用难以持久。目前临床上公认的治疗痛经有效的药物是非甾体抗炎药和口服避孕药,这些药物都具有难以完全避免的消化道、中枢神经系统以及肝肾等不良反应。手术治疗虽然也具有一定疗效,但因其局限性不易被患者接受。而中药治疗痛经则可因症治疗,标本兼治,充分发挥其疗效好、副作用少的优点,而越来越被人们所认可。
乳癖消颗粒是复方纯中药制剂,是治疗乳腺小叶增生的经典药物,临床疗效确切。临床研究中发现,乳癖消颗粒在治疗乳腺小叶增生时,能够缓解原发性痛经患者的临床症状。方中鸡血藤具有活血补血,调经止痛,舒筋活络之功效,用于月经不调,痛经,经闭等;红花活血通经,去瘀止痛,是为活血通经药;木香行气止痛;调中导滞,与丹皮、赤芍合用又能增强其活血散瘀、调经止痛之功效;昆布、海藻性味寒咸,软坚散结,与夏枯草、玄参、连翘同用增强其散结消肿之功效。蒲公英清热解毒,消肿散结,与漏芦、连翘、天花粉配伍能增强功效。牡丹皮、玄参、赤芍为清热凉血药,其中牡丹皮归心、肝、肾经,清热凉血,活血化瘀;玄参又能滋阴解毒;赤芍归肝经,具有养阴、行瘀、止痛、凉血、消肿之效。三药合用,可相互增强活血通经,散瘀消癥,行滞止痛的功效。鹿角补血壮阳益精,主治治疮疡肿毒,瘀血作痛;三七能止能行,具有散瘀止血,消肿定痛之功效。方中十五味中药配伍使用,通过处方优化及筛选,采用适合有效成分提取的新工艺对药材进行提纯,使有效成分含量显著提高,从而得到的本发明复方中药颗粒可达到清热凉血、软坚散结、活血止痛、调理冲任的目的,使得活血消淤,痛经症状得以好转。
发明内容:
本发明所要解决的技术问题是克服现有乳癖消颗粒部分组方未完仝提取所存在的不足,制备了针对原发性痛经治疗的复方中药颗粒剂。
本发明所需解决的技术问题是通过以下技术途径来实现的:
一种治疗原发性痛经的复方中药颗粒剂,药物的重量配比为:鹿角50~80重量份、蒲公英25~75重量份、昆布150~225重量份、天花粉10~30重量份、鸡血藤25~75重量份、三七25~75重量份、赤芍6~22重量份、海藻60~120重量份、漏芦20~45重量份、木香22~60重量份、玄参25~75重量份、丹皮50~80重量份、夏枯草25~75重量份、连翘10~30重量份、红花20~45重量份。
其中优选的原料配比为:鹿角66.8重量份、蒲公英44.5重量份、昆布173.5重量份、天花粉17.8重量份、鸡血藤44.5重量份、三七44.5重量份、赤芍13.4重量份、海藻86.8重量份、漏芦26.7重量份、木香35.6重量份、玄参44.5重量份、丹皮62.3重量份、夏枯草44.5重量份、连翘17.8重量份以及红花26.7重量份。
所述的复方中药颗粒剂的优选制剂是由下述制备方法制成的:
蒲公英、昆布、天花粉、鸡血藤、赤芍、海藻、漏芦、木香、牡丹皮、夏枯草、连翘以及红花加水煎煮两次,第一次加入8~12倍量的水,沸后煎煮2~4h,第二次加6~14倍量沸后煎煮1~3h,合并煎液,滤过,浓缩至相对密度为1.30~1.35;另取三七、鹿角以及玄参粉加60~80%乙醇提取两次,每次加入8~12倍量60~80%乙醇,沸后煎煮1~3h,合并煎液,滤过,浓缩至相对密度为1.30~1.35,混合后即得乳癖消提取物,将所得的乳癖消提取物,加入适当的辅料,按照常规工艺制备颗粒剂。
本发明颗粒剂在制剂成型过程中,采用溶剂提取法将三七、玄参以及鹿角中治疗痛经的有效成分尽可能多的提取出来,使其进入人体快速起效,有利于提高生物利用度,从而能提高临床疗效,更好地治疗痛经。
本发明颗粒剂的各项检查项目符合国家有关中药质量标准制定的要求,检验方法可行,经对10批样品20个检验数据的考察,符合专属性、重现性、稳定性的要求;药品的长期稳定性试验结果表明,本发明颗粒剂的外观形状及内在质量均稳定。总之,本发明颗粒剂的制备工艺合理可行,质量标准符合规范化的要求,适合于目前的生产设备和工业化大生产。
本发明所要解决的另一个技术问题是提供一种本发明颗粒剂的质量控制方法。
本发明所要解决的另一个技术问题是通过以下技术途径来实现的:
一种治疗原发性痛经的颗粒剂的质量控制方法,包括以下内容:
1.性状:本品为淡棕色颗粒,气微,味微甜;
2.粒度:取本品,照粒度测定法(《中国药典》2010年版一部附录XIB第二法,双筛分法)测定,应符合规定。
3.水分:取本品,照水分测定法(附录IXH)测定,应符合规定。
4.溶化性:取本品1袋,加热水200ml,搅拌5min,立即观察,应全部融化。
5.采用高效液相色谱法对颗粒中人参皂苷Rg1和哈巴俄苷的含量进行测定:人参皂苷Rg1不得少于8.0mg,哈巴俄苷不得少于0.40mg。
本发明复方中药颗粒剂比乳癖消颗粒在抗痛经药效上有了较大的提高,且本发明中的复方中药颗粒剂的质量标准增加了含量测定,质量标准的提高将更好的控制药品的质量。
本发明颗粒剂的用法与用量:每袋重8g,口服给药,一次1袋。
