Description

一种治疗盆腔炎的药物组合及其制剂
所属技术领域:
本发明涉及中药技术领域,具体涉及一种治疗盆腔炎的药物组合及其制剂。
背景技术:
盆腔炎是妇科常见病,多发病,其特点是病程长,反复发作,久治难愈,近年发病又有明显增多的趋势,并严重威胁着女性的健康。化学药物对此病疗效不佳,而中药治疗有一定的优势。根据本病的临床特点,中医药常将其归属于“痛经”、“癥瘕”、“带下”、“崩漏”等病范畴进行治疗,目前市售治疗慢性盆腔炎的中药成方制剂尚少,特别是针对慢性盆腔炎湿热瘀结证开发的中药复方制剂更少。
本病多因房事不节,不注意经、产期调摄,以及个人卫生习惯不良,而致湿热、湿毒之邪内侵,与气血互结,蕴积胞脉胞络,气滞血瘀,火毒湿热,郁滞下焦,气血渐耗,阴阳失调,迁延难愈。临床出现以湿热郁结型最为常见。多因内蕴或外感湿热,留连冲任、胞宫,或感邪毒湿热,病后邪气虽除,但局部病变未愈,或邪未除尽而留连,局部气血流通受阻,因而发生疼痛,或因盆腔癥瘕压迫,瘀阻气血而痛,或因久坐、久站、久负重,损气而血迟滞不畅,瘀于盆腔而腹痛及腰骶,或因情志伤肝,累及冲任气血失调,湿热瘀结,致发本病证。
由此可见,慢性盆腔炎湿热瘀结型当采用清热利湿,活血化瘀之法。现在也有制剂采用白花蛇舌草清热利湿,败酱草行气祛瘀止痛,二者合用具有清热解毒消痈止痛之功效。但功效上偏重于清热解毒利湿作用,而行气祛瘀稍弱。因此现有技术存在的问题是疗效不很理想。
发明内容:
本发明要提供一种治疗盆腔炎的药物组合及其制剂,以克服现有技术存在的疗效不很理想的问题。
为克服现有技术存在的问题,本发明的技术方案是:一种治疗盆腔炎的药物组合,包括下述重量份数计的原料制备而成,丹参2~6份;苦参2~6份;蒲公英3~5份;延胡索3~5份;薏苡仁1~3份。
上述中药还包括下述重量份数计的原料制备而成:鸡冠花3~5份漏芦1~3份。疗效更优。
上述中药的优选方案是:丹参4~6份;苦参4~6份;蒲公英4~5份;延胡索4~5份;薏苡仁2~3份;鸡冠花4~5份;漏芦2~3份。
一种治疗盆腔炎的药物组合的制剂,包括任何一种形式的药物制剂。
方义解释:
历代医家的论述可知,中医学认为以上病症的病因不外乎湿热、寒凝、气滞、痰结、血瘀诸症,病性或实或虚,或虚实夹杂,病机特点为胞宫脉络瘀滞内阻,故治疗上或清热利湿,或温经散寒,或理气行滞,或除痰逐湿,或活血化瘀,或扶正固本,但活血祛瘀之法常贯穿始末。本发明的主要功效是:活血化瘀,清热利湿,主治慢性盆腔炎,症见下腹胀痛或刺痛,痛处固定;腰骶胀痛;带下量多,色黄质稠,神疲乏力,经期腹痛加重,月经量多或伴经期延长,小便黄,大便干燥或溏而不爽,舌质红或暗红,或见边尖瘀点或瘀斑,苔黄腻或白腻,脉弦滑或弦涩等属湿热瘀结证者。
它的作用机理是:针对本证湿热蕴结的病机,方中用丹参活血祛瘀,止痛通经;苦参清热燥湿,二者合为君药。用元胡助君药加强活血止痛之效;蒲公英清热解毒,消肿散结;薏苡仁健脾以祛湿,用在方中可使脾气健运,湿浊顿消,三药共为臣药。再佐以鸡冠花收敛止血,止带;漏芦清热解毒。综观全方,选药精当,切中病机,标本兼治,诸药合用,共奏活血化瘀,清热利湿之效,经临床验证,确为治疗慢性盆腔炎的有效良药。
与其它药物相比,本发明重用丹参,祛瘀止痛,活血通经,用于月经不调,经闭痛经,癥瘕积聚,胸腹刺痛。针对主要病症理调理气血,再加苦参清热燥湿,切中湿热之病因,药力适中,配合诸药,自然在疗效上更胜一筹。
与现有技术相比,本发明的优点是:
本发明采用随机双盲,阳性药物妇炎康片平行对照的原则,运用双盲双模拟方法进行,总有效率大于93%。观察治疗前后,血液流变学多项指标均有显著改善,治疗前后全血高低切粘度,血浆粘度均有明显差异。动物实验表明,本发明具有抗渗出和抗增殖性炎症的作用,能增强小鼠单核细胞、巨噬细胞的吞噬功能。使盆腔瘀血减轻,促进增生性病变软化与吸收,提高免疫功能,达到治疗目的。针对慢性盆腔炎湿热瘀结所致者疗效更突出。
具体实施方式:
下面将通过具体实施例对本发明作进一步描述:
实施例1:丹参2份;苦参6份;蒲公英5份;延胡索3份;薏苡仁1份;
实施例2:丹参6份;苦参2份;蒲公英3份;延胡索5份;薏苡仁3份;
实施例3:丹参3份;苦参4份;蒲公英4份;延胡索4份;薏苡仁2份;鸡冠花4份;漏芦2份。
实施例4:丹参6份;苦参6份;蒲公英5份;延胡索3份;薏苡仁3份;鸡冠花5份;漏芦3份。
实施例5:丹参6份;苦参6份;蒲公英5份;延胡索5份;薏苡仁3份;鸡冠花3份;漏芦1份。
由于配伍更合理,实施例3~5优于实施例1和2,其中又以实施例5为最佳实施例。
将它们制备成片剂、颗粒剂、软胶囊、硬胶囊等口服制剂。
药效学实验:将实施例5制备成片剂进行了临床前主要药效学的实验研究。本发明的药效学试验的剂量采用大鼠:4g/kg、2g/kg、1g/kg,相当于临床拟用剂量的53倍、27倍、13倍。小鼠:8g/kg、4g/kg、2g/kg。阳性药妇炎康片大鼠采用3.75g/kg,相当于人用剂量50倍。扶他林以0.01g/kg灌胃给予大鼠,相当于人用剂量8倍,以0.015g/kg灌胃给予小鼠,相当于人用剂量12倍。实验结果总结如下:
(一)本发明制剂对子宫内注射混合菌液致大鼠慢性盆腔炎模型的治疗作用:
试验结果显示:采用混合菌悬液注入划伤的子宫内造成大鼠慢性盆腔炎,造模30天,灌胃给药28天,模型组大鼠子宫粘膜上皮明显坏死变性,肌层和固有层均有明显结缔组织增生和炎细胞浸润,肌层排列紊乱,管腔有一定粘连阻塞,浆膜层有散在炎细胞浸润;血液流变学指标中全血粘度、流阻、卡森应力、红细胞压积、红细胞电泳时间等指标均显著升高;体外血栓的长度、湿重和干重显著增加。本发明制剂大、中、小三个剂量及阳性药与模型组比较,子宫粘膜上皮、肌层和固有层结缔组织增生、浆膜层炎细胞浸润程度均显著的得到可不同程度改善;部分血液流变学指标有显著性改善;血栓长度显著减小。综合上述结果可见采用混合菌悬液注入划伤的子宫内造成大鼠慢性盆腔炎的模型是成功和可行的。本发明制剂对混合菌悬液致大鼠慢性盆腔炎有显著的治疗作用,并有一定的量效关系。
(二)本发明制剂对双侧输卵管内注射苯酚胶浆致大鼠输卵管炎症模型的治疗作用:
试验结果显示:采用苯酚胶浆注入双侧子宫内造成大鼠慢性盆腔炎,造模7天,灌胃给药28天,模型组大鼠子宫粘膜上皮明显坏死变性,肌层和固有层均有明显结缔组织增生和炎细胞浸润,肌层排列紊乱,管腔有一定粘连阻塞,浆膜层有散在炎细胞浸润;血液流变各指标中多项指标均显著升高;体外血栓的长度、湿重和干重显著增加;子宫卵巢脏体比值显著增加,输卵管通畅率显著减小。本发明制剂大、中、小剂量及阳性药与模型组比较,子宫粘膜上皮、肌层和固有层结缔组织增生均可不同程度显著的得到改善;大鼠血液流变学有显著的改善的作用,本品的大、中个剂量的血栓湿重、长度显著减小;本品的大、中二个剂量和妇炎康的子宫卵巢脏体比值显著减小,本品的大剂量输卵管通畅率显著增加。综合上述结果可见采用苯酚胶浆注入双侧子宫内造成大鼠慢性盆腔炎的模型是成功和可行的。本发明制剂对苯酚胶浆致大鼠慢性盆腔炎有显著的治疗作用,并有一定的量效关系。
(三)本发明制剂对异物置入大鼠子宫致子宫炎症模型的治疗作用
试验结果显示:采用单侧子宫内放置塑料环造成大鼠慢性盆腔炎的模型,造模3天,灌胃给药28天,模型组大鼠部分子宫有包块、明显肿张,大量积液,子宫粘膜上皮明显坏死变性,肌层和固有层均有明显结缔组织增生和炎细胞浸润,肌层排列紊乱,管腔有一定粘连阻塞,浆膜层有散在炎细胞浸润;血液流变学多项指标均显著升高;体外血栓的长度、湿重和干重显著增加;子宫卵巢的肿胀度显著增加。本发明制剂大、中、小剂量及阳性药组大鼠子宫粘膜上皮、肌层和固有层结缔组织增生、浆膜层炎细胞浸润程度均显著的得到可不同程度改善,管腔未见粘连阻塞或扩张;血液流变学有一定的改善作用,本品的大剂量的血栓长度显著减小;本品的三个剂量子宫卵巢的肿胀度显著减小。综合上述结果可见采用单侧子宫内放置塑料环造成大鼠慢性盆腔炎的模型是成功和可行的。本发明制剂对子宫内放置异物致大鼠慢性盆腔炎有显著的治疗作用,并有一定的量效关系。
(四)抗炎作用
1、对大鼠棉球肉芽肿形成的影响
大鼠腋下置入经无菌处理的棉球后,灌胃给药15天,实验结果显示:本发明制剂三个剂量组和妇炎康的肉芽肿的重量与对照组比较显著降低(P<0.001),故本发明制剂具有抑制大鼠棉球肉芽肿形成的作用。
2、对大鼠足跖肿胀的影响
大鼠足跖注射角叉菜胶后,灌胃给药15天,实验结果显示:与对照组比较,本发明制剂的三个剂量组在角叉菜胶致炎后3、4、5、6h均具有显著的抑制足肿胀的作用(P<0.01-P<0.001),阿斯匹林组在致炎后1、3、4、5h均显示出较强的抑制足跖肿胀的作用(P<0.05-P<0.001),扶他林在致炎后1、2、3、4、5、6h均显示出较强的抑制足跖肿胀的作用(P<0.05-P<0.001)。结果提示:本发明制剂对角叉菜胶致大鼠的足跖肿胀具有显著的抑制作用。
3、对小鼠耳肿胀的影响
实验结果显示:灌胃给药5天,与对照组比较,本发明制剂8g/kg能显著抑制二甲苯致小鼠的耳肿胀程度(P<0.05),扶他林0.015g/kg亦能显著抑制二甲苯致小鼠的耳肿胀程度(P<0.01)。
(五)活血化瘀作用:
1、本发明制剂对血瘀模型大鼠的血液流变学及血栓形成的影响:
大鼠皮下注射肾上腺素加冰水刺激,形成血瘀模型,实验结果显示:①、对血瘀模型大鼠血液流变学的影响:模型组与水对照组比较,全血粘度、流阻、卡森应力、红细胞电泳时间、血沉等指标均显著升高(P<0.05、P<0.01);各给药组与模型组比较,本发明制剂的大、中剂量部分血液流变学指标有显著性差异(P<0.05、P<0.01)。大剂量组的作用较中剂量组强,起效剂量2g/kg。川芎嗪对血液流变学部分指标亦有显著的降低作用,妇炎康无明显影响。②、对体外血栓形成的影响:模型组与水对照组比较,体外血栓的长度、湿重和干重显著增加(P<0.001),各给药组与模型组比较,本品的三个剂量和妇炎康的血栓的湿重显著减小(P<0.05、P<0.01),大、中二个剂量和妇炎康的血栓干重显著减少(P<0.05)。因此本品具有降低血瘀模型大鼠血液粘度,降低血栓形成重量的作用。
2、本发明制剂对小鼠微循环障碍的改善作用:
实验结果:①、对耳廓毛细血管管径的影响:本发明制剂的大、中2个剂量组、川芎嗪注射液和妇炎康药后,毛细血管动脉管径和静脉管径显著增加,与水对照组比较,有显著性差异(P<0.05-0.01),本发明制剂的起效剂量为4g/kg,起效时间为60分。②对耳廓毛细血管血液流速的影响:本发明制剂的大、中2个剂量组、川芎嗪注射液和妇炎康给药后,毛细血管动脉血流速度和静脉血流速度显著增加,与水对照组比较,有显著性差异(P<0.05-0.01),本发明制剂的起效剂量为4g/kg,起效时间为60分。因此本品具有改善正常小鼠微循环的作用,起效剂量4g/kg,起效时间为60分。
(六)镇痛作用:采用冰醋酸致小鼠腹痛和热刺激致小鼠疼痛,本发明制剂具有非常显著减少动物扭体次数(P<0.001)和延长小鼠甩尾潜伏期(P<0.05)的作用,对冰醋酸致小鼠腹痛镇痛作用较热刺激致小鼠疼痛的作用强。
(七)小鼠体外抑菌作用:
结果显示,本发明制剂提取液对金黄色葡萄球菌、表皮葡萄球菌和乙型溶血性链球菌有明显的抑制和杀灭作用,其MIC和MBC分别为3.125mg/ml和12.5g/ml,3.125mg/ml和12.5mg/ml及3.125mg/ml和6.5mg/ml。对绿脓假单胞菌和白色念珠菌有较强的抑制和杀灭作用,其MIC和MBC分别为6.25mg/ml和25mg/ml,12.5mg/ml和25mg/ml,对大肠埃希氏菌和变形杆菌也有一定的作用。表明本发明制剂能够有效地抑制和灭活常见妇科致病菌。
实验结果显示:本发明制剂对混合菌悬液、苯酚胶浆和子宫内放置异物致大鼠慢性盆腔炎有显著的治疗作用,并有一定的量效关系;具有抑制大鼠棉球肉芽肿形成的作用;对角叉菜胶致大鼠的足跖肿胀具有显著的抑制作用;能显著抑制二甲苯致小鼠的耳肿胀程度;具有降低血瘀模型大鼠血液粘度,降低血栓形成重量的作用;具有改善正常小鼠微循环的作用;对冰醋酸致小鼠腹痛具有显著的镇痛作用和对热刺激致小鼠疼痛本发明制剂具有明显的抑制作用;能够有效地抑制和灭活常见妇科致病菌。
毒理实验研究:
1、本发明制剂的急性毒性试验:
给ICR小鼠以最大浓度50%灌胃本发明制剂药粉混悬液,未测出LD50,故作最大给药量测试。测得其最大给药量为60g药粉/kg,相当于280g生药/kg,相当于人用量的800倍,故本发明制剂灌胃给予小鼠无急性毒性作用。
2、大鼠的长期毒性试验:
本发明制剂具有活血化瘀,清热利湿之功效,主治慢性盆腔炎血瘀兼湿热证。以10g/kg、5g/kg和2.5g/kg(分别相当于成人日用剂量的133、66、33倍)灌胃给于大鼠13周。处死部分动物进行病理学、毒理学、血液学、血液生化指标及尿液等项目的检查,部分动物停药恢复4周后,重复上述检查。实验结果显示:在本实验条件下,本发明制剂对大鼠的一般情况、体重、饮食饮水、血液学、血液生化学、系统解剖、脏器系数和组织病理学及尿液均无明显影响,未发现长期毒性反应,恢复期亦无延迟性毒性反应,提示:大鼠无毒反应剂量为10g药粉/kg/日。
总之,药效学的实验研究支持其功能主治,毒理学的研究表明本品用于临床具有有效性和安全性。
