Description
技术领域:
本发明属于药物制剂领域,公开穿心莲内酯浓缩型液体组方及其医药用途。
背景技术:
穿心莲内酯(Andrographolide)为爵床科植物穿心莲中提取得到的二萜内酯类化合物,是中药穿心莲的主要有效成分之一,具有清热解毒,凉血消肿等功能,对细菌性与病毒性上呼吸道感染及痢疾有特殊疗效,被誉为天然抗生素药物。其药理作用主要包括以下几方面:
(1)抗病原微生物作用
动物实验表明:穿心莲内酯及新穿心莲内酯均有抑制和延缓肺炎双球菌或溶血性乙型链球菌所引起的体温升高作用,但穿心莲内酯比新穿心莲内酯的作用较强。
体外实验表明:穿心莲有一定抗HIV作用。
(2)解热作用
穿心莲内酯对家兔内毒素发热、肺炎球菌或溶血性链球菌所致发热有不同程度的解热作用。穿心莲甲、乙、丙、丁素对伤寒、副伤寒菌苗所致发热家兔或2,4-二硝基苯酚所致发热大白鼠的解热作用依次减弱。
(3)抗炎作用
穿心莲甲、乙、丙、丁素均有不同程度的抗炎作用,1g/kg灌服能抑制二甲苯或醋酸所致小鼠皮肤或腹腔毛细血管通透性的增高,减少Selye肉芽囊中巴豆油所致急性渗出液量,但对肉芽组织增生无明显影响。能抑制蛋清性大鼠脚肿的发展,但切除肾上腺后作用消失。丁素的抗炎作用最强,丙素、甲素、乙素次之。
(4)对机体免疫功能的影响
有报道认为,穿心莲可能对细胞免疫的某些环节有作用。其水煎剂在体外能提高人白细胞吞噬金黄色葡萄球菌的能力,口服穿心莲能使人对旧结核菌素所致的皮肤延缓型超敏反应增强。穿心莲制剂新炎得平(内含酯和酮),可提高小鼠血清溶菌酶水平,增强腹腔巨噬细胞和中性粒细胞的吞噬能力。连续给家兔或小鼠以穿心莲内酯磺化物,可明显增加外周血吞噬细胞对肺炎球菌或金黄色葡萄球菌的吞噬能力,穿心莲甲素注射液及喜炎平注射液亦能增强吞噬细胞功能。脱水穿心莲内酯琥珀酸半酯对2,4-二硝基氯苯所致小鼠迟发型超敏反应也有抑制作用。
(5)抗生育作用
穿心莲有明显的中止妊娠作用。穿心莲口服能使小鼠避孕、孕兔流产。水煎剂腹腔注射对小鼠的着床、早孕、中孕、晚孕等不同时期均有显著的中止作用。肌注、皮下注射、灌服、腹腔注射、静脉注射及宫腔内注射均能产生抗早孕效果,其中以腹腔、静脉和宫内注射效果最好。宫腔内注射,用量既小,效果又佳。若将外源性孕酮或黄体生成素释放、激素(LH-RH)与穿心莲同时注射,则可防止流产,这提示,穿心莲可能有对抗体内孕酮的作用,从而引起流产。有人认为,穿心莲对体外培养的胎盘绒毛滋养层细胞的生长有一定的抑制作用。研究表明:穿心莲内酯的一些半合成衍生物亦有不同程度的抗早孕效果,脱水穿心莲内酯衍生物-穿-4对小鼠和大鼠均有良好的抗早孕作用,是值得进一步研究的一个避孕新药,该药对胎盘滋养叶细胞有显著的影响,可使胎盘绒毛萎缩、细胞数目减少,合体细胞和朗罕细胞消失、间质水肿出血。
(6)利胆保肝作用
穿心莲对大鼠有利胆作用,并可增加大鼠肝重,缩短环己巴比妥钠所致之睡眠时间。穿心莲内酯预先给药能对抗四氯化碳、D-半乳糖胺和乙酰胺基酚造成的肝毒性作用,能分别显著降低SGPT、SGOT、SALP、HTG水平。有报道指出,穿心莲的甲醇浸膏有毒性,可促进肝损伤大鼠的死亡。
(7)抗肿瘤作用
脱水穿心莲内酯琥珀酸半酯对W256移植性肿瘤有一定的抑制作用。脱水穿心莲内酯二琥珀酸半酯氢钾制成精氨酸复盐(简称穿琥氨酸),不论大、中、小剂量对肿瘤细胞均有抑制作用,且随剂量的增加而作用增强,抑瘤效果确实、稳定。体外实验证明:穿心莲对培养的乳腺癌细胞DNA合成有抑制作用。
(8)其他作用
炎琥宁及穿琥宁注射液有明显镇静作用,能缩短戊巴比妥钠对小鼠麻醉的潜伏期、延长麻醉时间,并能使阈下量的戊巴比妥钠引起麻醉。
穿心莲内酯可增加肾上腺皮质功能,穿心莲甲、乙、丙、丁素在较大剂量时可使幼年小鼠胸腺萎缩。
目前穿心莲内酯在临床上主要用于菌痢、钩端螺旋体病、脑膜炎、肺炎、增强肾上腺皮质功能、上呼吸道感染。针对临床上病毒感染急症的需求,将该品内酯结构中引入不同的亲水基团,增强其水溶性,提高疗效。由此已制成了多种穿心莲内酯的针剂,目前临床上应用较为广泛的穿琥宁针、炎琥宁针、莲必治针是本类的代表性药物,已被卫生部及国家中医药管理局列为急诊科必备药品之一。
现有穿心莲内酯的上市剂型为片剂、胶囊和滴丸,它们普遍存在载药量小、辅料用量大、服用剂量大的缺陷,截至目前,未见将穿心莲内酯制备成浓缩型液体组方的研究或报道。
发明内容:
发明人经过深入研究,提供了穿心莲内酯浓缩型液体组方及其医药用途。
本发明所提供的穿心莲内酯浓缩型液体组方,其特征在于:该浓缩型液体组方包括活性化合物穿心莲内酯、增溶剂、混合溶媒、抗氧剂和pH调节剂,其中:

本发明所提供的穿心莲内酯浓缩型液体组方,其特征在于:穿心莲内酯选自穿心莲总内酯、穿心莲内酯、新穿心莲内酯、脱水穿心莲内酯、去氧穿心莲内酯穿心莲甲素、穿心莲乙素、穿心莲丙素、穿心莲丁素、脱水穿心莲内酯琥珀酸半酯中的一种,缩型液体组方中穿心莲内酯的浓度为5~50mg/mL。
本发明所提供的穿心莲内酯浓缩型液体组方,其特征在于:所述的穿心莲内酯浓缩型液体组方可以用灭菌注射用水、葡萄糖注射液、0.9%氯化钠注射液及0%~20%的F68溶液稀释后口服或注射给药,也可以与填充剂和(或)冻干保护剂混合,经过喷雾干燥或冷冻干燥技术制备成粉末制剂或冻干制剂,所得的粉末制剂或冻干制剂可以用来制备成药学上可接受的片剂、胶囊剂、颗粒剂、散剂、软膏剂、混悬剂、糖浆剂、口服液、栓剂、滴鼻剂或注射用粉针剂,以适当的方式给药。

与现有技术相比,本发明带来了明显的技术效果,主要体现在:
(1)本发明所提供的穿心莲内酯浓缩型液体组方使得穿心莲内酯制剂以浓缩、稳定的形式存在,显著提高了穿心莲内酯在单位体积制剂中的浓度,减小了治疗剂量所需制剂的体积,进而降低了治疗剂量下制剂的包装体积,使得制剂在储存和运输过程中所需的人力、物力和财力显著降低,另外,由于治疗剂量的制剂体积及数量显著降低,方便了医生和患者的使用。
(2)本发明所提供的穿心莲内酯浓缩型液体组方可保证活性化合物穿心莲内酯以分子形式稳定的存在,特别有利于防止药物在储存过程中析出。
需要特别强调的是:本发明提供的穿心莲内酯浓缩型液体组方,重点是在“浓缩型”上,虽然组方中有相对多的增溶剂来增溶穿心莲内酯,但是本发明提供的增溶剂与穿心莲内酯的比例必须是在浓缩液中的比例,若单独以本发明所述的增溶剂与穿心莲内酯的比例来制备穿心莲内酯非浓缩液制剂,所制备的制剂稳定性极差,室温放置1小时就会析出大量的药物,这直接限制了用此方法制备的穿心莲内酯注射液的应用,就算是将其勉强用于口服给药,但其生物利用度势必会大打折扣。
具体实施方式:
为了更清楚的理解本发明,以下通过实施例和试验例来对本发明做进一步的详细说明,但不仅限于此。

表4pH对穿心莲内酯浓缩型液体组方稳定性的影响
结果表明,将不同pH值的制剂于60℃下放置5天之后,在pH值大于7时穿心莲内酯含量均有明显的下降,而pH值在2.0~6.0时穿心莲内酯的含量无明显变化。因此,为保证本发明提供的穿心莲内酯浓缩型液体组方的稳定性,应将该浓缩型液体组方的pH值维持在2.0~6.0的范围内。
