在含有西洛他唑或其可药用盐作为有效成分的注射用西洛他唑水性药物制剂中加入环糊精化合物可以增加西洛他唑或其可药用盐的水溶解度,得到溶液状态下的历时稳定性得到改善的含有西洛他唑或其可药用盐的注射用水性药物制剂。
Description
技术领域
本发明涉及注射用水性药物制剂,含有西洛他唑(cilostazol)或其可药用盐作为有效成分。
发明背景
最近公布的厚生劳动省厚生科学研究班的治疗证明书的报告说,对于急性心肌梗塞或脑梗塞的急性期的患者来说,抗血小板药物是首选的疗法。但是,一个严重的问题是,市售的全部抗血小板药物均为口服使用,这使得例如对刚刚患上急性心肌梗塞或脑梗塞的患者,特别是正处在急性期的患者给用药物变得困难,另外也难以期待口服给用时具有速效性。
市售的全部抗血小板药物制剂均为口服使用的原因是这些制剂中所含的全部有效成分难以溶于水。西洛他唑作为一种通常使用的抗血小板药物也不例外,在水中极难溶解,常温下的溶解度低至约3μg/ml。
由于西洛他唑在水中仅稍微溶解,因此除JP-A1-H10-175864所述的以外,还几乎没有关于含有该药物作为有效成分的水性药物制剂的描述,该文献记载的是一种注射用水性药物制剂,其含有西洛他唑作为有效成分,并且含有聚乙二醇4000和聚氧乙烯山梨糖醇酐单油酸酯,但不含环糊精化合物。但是,这样的水性药物制剂是不现实的,因为这样的水性药物制剂的重现性未必好,并且即使可以得到这样的药物制剂,也可能导致在暂时放置时西洛他唑会析出。因此,需要一种更方便或有用的含有西洛他唑的注射用水性药物制剂。本发明人想要开发一种新的含有西洛他唑的水性药物制剂,它是现成的,即不必在使用时溶解,并且即使长时间储存后也保持稳定,不会析出西洛他唑沉淀。
发明的公开
本发明的目的是通过提高西洛他唑或其可药用盐的溶解度,提供一种含有西洛他唑、溶液状态下的历时稳定性得到提高的注射用水性药物制剂。
本发明人为实现其目的进行了深入细致的研究,结果发现,加入环糊精化合物会将西洛他唑或其可药用盐的水溶解度增加到出入意料的程度。他们还发现,环糊精化合物的加入不仅提高了西洛他唑或其可药用盐的水溶解度,而且增强了含有西洛他唑化合物为有效成分的注射用水性药物制剂在溶解状态下的历时稳定性,从而使得不仅可以提供通过在使用前溶解而使用的水性药物制剂,而且可以提供现成的药物制剂。因此,本发明提供的注射用水性药物制剂使得可以解决上述的事实带来的问题,即仅有口服制剂可用的问题,并且给例如急性心肌梗塞或脑梗塞患者提供易于给用且具有速效性的注射用水性药物制剂。
本发明人基于上面的发现进行了进一步的研究,完成了本发明。

(1)一种注射用西洛他唑水性药物制剂,含有西洛他唑或其可药用盐作为有效成分,并含有环糊精化合物;

实施发明的最佳方式
本发明的注射用水性药物制剂含有西洛他唑或其可药用盐作为有效成分。
西洛他唑为6-[4-(1-环己基-1,2,3,4-四唑-5-基)丁氧基]-3,4-二氢喹诺酮,化学结构如下所示。
式
西洛他唑的可药用盐可以通过让西洛他唑与药用容许的酸反应很容易地制备。作为这样的药用容许的酸,可以举出例如,无机酸如盐酸、硫酸、磷酸、氢溴酸等,以及有机酸如草酸、马来酸、富马酸、苹果酸、酒石酸、柠檬酸、苯甲酸等。
注射用水性药物制剂的特征是,所述的制剂除含有上述的有效成分外,还含有环糊精化合物。这里,环糊精化合物是指环糊精或环糊精衍生物或其可药用盐。
可用于本发明的环糊精化合物包括含有6-12个葡萄糖单元的环状低聚糖。可用于本发明的环糊精衍生物包括用任何其它官能团取代葡萄糖单元的2、3和6位上的部分或全部羟基得到的化合物。作为所述的环糊精或其衍生物的具体例子,可以举出由下面的通式表示的化合物:
式
(其中,n表示6-12的整数;各重复单元中的R1、R2和R3独立地表示氢、烷基、单羟基烷基、二羟基烷基、磺基烷基、羧基烷基或糖残基)。
上式中,作为由R1-R3表示的烷基,可以举出C1-4烷基,例如甲基、乙基、丙基等。作为由R1-R3表示的单羟基烷基,可以举出单羟基-C1-4烷基,例如羟甲基、2-羟基乙基、2-羟基丙基等。作为由R1-R3表示的二羟基烷基,可以举出二羟基-C1-4烷基,例如二羟基甲基、2,2-二羟基乙基、二羟基丙基等。作为由R1-R3表示的磺基烷基,可以举出磺基-C1-4烷基,例如磺甲基、2-磺基乙基、磺基丁基等。作为由R1-R3表示的羧基烷基,可以举出羧基-C1-4烷基,例如羧甲基、2-羧基乙基等。作为由R1-R3表示的糖残基,可以举出例如,葡糖基、麦芽糖基、4-α-葡糖基麦芽糖基等。
优选可用于本发明的环糊精化合物为由上面的通式表示,其中n=6的α-环糊精或其衍生物;由上面的通式表示,其中n=7的β-环糊精或其衍生物;由上面的通式表示,其中n=8的γ-环糊精及其衍生物;或由上面的通式表示,其中n=9的δ-环糊精及其衍生物。
作为上述的环糊精化合物的衍生物中更优选的例子,可以举出烷基衍生物、羟烷基衍生物、磺基烷基醚衍生物、附加有糖基的环糊精等。
作为上述的环糊精的烷基衍生物,可以举出,例如,二甲基-α-环糊精、二甲基-β-环糊精、二甲基-γ-环糊精等。
作为上述的环糊精的羟烷基衍生物,可以举出,例如,2-羟丙基-α-环糊精、2-羟丙基-β-环糊精、2-羟丙基-γ-环糊精等。
作为上述的环糊精的磺基烷基醚衍生物,可以举出,例如,磺基丁基醚-α-环糊精、磺基丁基醚-β-环糊精、磺基丁基醚-γ-环糊精等。
作为上述的附加有糖基的环糊精的例子,可以举出,例如,葡糖基-α-环糊精、葡糖基-β-环糊精、葡糖基-γ-环糊精、麦芽糖基-α-环糊精、麦芽糖基-β-环糊精、麦芽糖基-γ-环糊精等。
本发明中,从提高西洛他唑的水溶解度考虑,其中优选使用环糊精的磺基烷基醚衍生物,更优选使用磺基丁基醚-β-环糊精。这些化合物以碱金属盐如钠盐等的形式方便使用。
有时,环糊精的副作用如肾毒性和溶血可能成为讨论的问题,但在上述的磺基丁基醚-β-环糊精中,四取代(分子中的约4个位置被磺基丁基醚化)和七取代(分子中的约7个位置被磺基丁基醚化)的化合物适合使用,因为它们几乎没有副作用。其中,更优选七取代的化合物。
上述的环糊精及其衍生物可以根据已知的方法很容易地制备。另外,市售的环糊精及其衍生物,例如作为α-环糊精的Celdex A-100(商品名,日本食品化工有限公司制);作为β-环糊精的Celdex B-100(商品名,日本食品化工有限公司制);作为γ-环糊精的Celdex C-100(商品名,日本食品化工有限公司制);作为2-羟丙基-β-环糊精的CeldexHP-β-CD(商品名,日本食品化工有限公司制);和作为磺基丁基醚-β-环糊精的Captisol(商品名,CyDex Inc.制)可以适当使用。
本发明的注射用水性药物制剂可以含有上述的环糊精及其衍生物的可药用盐作为环糊精化合物。作为可药用盐,可以举出,例如,与无机酸(例如,盐酸、硫酸、硝酸等)、有机酸(例如,碳酸、重碳酸(bicarbonic acid)、琥珀酸、乙酸、丙酸、三氟乙酸等)、无机碱(例如,碱金属如钠或钾等;碱土金属如钙或镁等)或有机碱化合物(例如,有机胺如三乙胺等;碱性氨基酸如精氨酸等)的盐。
本发明中,注射用水性药物制剂是指上述的本发明的有效成分溶解于水或含水的溶剂中的制剂。作为水,通常可以使用无菌水、或更优选使用无热原质的无菌水,作为含水的溶剂,可以适当使用那些已知并用于制备药物的溶剂,例如生理盐水、PBS(磷酸盐缓冲盐水)或含乳酸的林格氏溶液(Ringer’s solution)。另外,本发明的注射用水性药物制剂可以通过利用已知的干燥方法如冷冻干燥或减压干燥将上述的溶液状态的注射用水性制剂干燥,得到粉末或颗粒,然后在使用时将该粉末或颗粒溶解于水或含水溶剂中这样的方式来制备。
在本发明的注射用水性制剂中,西洛他唑或其可药用盐的含量尽管由于其随制剂的使用目的等变化故难以一概而论,但上述有效成分的浓度为约0.01-10mg/mL,或优选约0.05-0.5mg/mL,或更优选约0.1-3mg/mL,或最优选约0.5-2mg/mL。另外,本发明的注射用水性药物制剂是上述的在使用时溶解的形式时,上述的西洛他唑或其可药用盐的浓度是指将该有效成分溶解于水或含水溶剂中时的浓度。
在本发明的注射用水性药物制剂中,环糊精化合物的含量尽管由于其随制剂的使用目的而变化故难以一概而论,但对于每1摩尔西洛他唑而言,其浓度为约1-4000摩尔,优选约1-200摩尔,更优选约1-100摩尔,最优选约30-50摩尔。
另外,当七取代的磺基丁基醚-β-环糊精钠盐用作环糊精化合物时,更优选将其在水性药物制剂中的浓度调节至约100-400mg/mL。
除上述的有效成分和环糊精化合物外,本发明的注射用水性药物制剂还可以含有添加剂。作为添加剂,任何通常用于注射用水性药物制剂技术领域的都可以适当使用。
作为所述的添加剂,可以具体举出张力调节剂、稳定剂、缓冲剂、防腐剂、螯合剂、抗氧剂、止痛剂、增溶剂等。作为张力调节剂,可以举出,例如,糖如葡萄糖、山梨糖醇、甘露醇等、氯化钠、甘油、丙二醇、聚乙二醇等。作为稳定剂,可以举出,例如,亚硫酸钠等。作为缓冲剂,可以举出,例如,硼酸盐缓冲剂、磷酸盐缓冲剂、柠檬酸盐缓冲剂、酒石酸盐缓冲剂、乙酸盐缓冲剂等。作为防腐剂,可以举出,例如,对羟基苯甲酸酯、苯甲醇、氯甲酚、苯乙醇、苄索氯铵(benzethonium chloride)等。作为螯合剂,可以举出,例如,乙二胺四乙酸钠盐、柠檬酸钠等。作为抗氧剂,可以举出,例如,亚硫酸钠、亚硫酸氢钠、抗坏血酸钠、硫代硫酸钠等。作为止痛剂,可以举出,例如,白蛋白、多元醇如甘油和丙二醇、利多卡因盐酸盐、苯甲醇等。作为增溶剂,可以举出,例如,葡聚糖、聚乙烯基吡咯烷酮、苯甲酸钠、乙二胺、水杨酰胺、烟酰胺、硬化蓖麻油聚氧乙烯醚衍生物等。其中,优选加入选自葡聚糖和聚乙烯基吡咯烷酮的至少一种增溶剂,因为这使得可以提高本发明的注射用水性药物制剂的溶解稳定性(沉淀物析出的防止)。对于加入的增溶剂的量没有特别的限制,其合适量根据使用的西洛他唑及环糊精化合物的量适当选择。
本发明的水性药物制剂可以含有通常用于该技术领域中的pH调节剂,以调节pH值。PH调节剂大致地分为两类:酸和碱。具体地,作为酸,可以举出,例如,抗坏血酸、盐酸、葡萄糖酸、乙酸、乳酸、硼酸、磷酸、硫酸、酒石酸、柠檬酸等;作为碱,可以举出,例如,氢氧化钾、氢氧化钙、氢氧化钠、氢氧化镁、单乙醇胺、二乙醇胺、三乙醇胺等。作为其它的pH调节剂,也可以举出氨基酸,如甘氨酸、组氨酸、ε-氨基己酸等。
本发明的注射用水性药物制剂可以根据通常的方法制备:例如,首先把将要包含在本发明的注射用水性药物制剂中的成分(以下称为“成分”)溶于水或含水溶剂中。
成分的混合顺序不重要。即,所有的成分可以同时混合,或某些成分可以先溶解在上述溶剂中,然后将剩余的成分溶于所得溶液中。或者,更优选将环糊精化合物先溶于上述溶剂中,然后在其中加入西洛他唑或其可药用盐。此时,如果需要,可以混合上述的添加剂,并且根据自身已知的方法确定混合顺序。
然后,优选将所得的溶液通过利用膜过滤器的过滤灭菌、利用高压灭菌器的加压热灭菌、分段灭菌法等进行灭菌处理。其中,优选进行过滤灭菌。这样得到的溶液的pH在约6-8范围内是合适的。
当本发明的注射用水性药物制剂以液体得到时,上述灭菌后得到的溶液可以填充入安瓿中,然后熔融密封。
根据本发明的方法,环糊精的加入增加了有效成分在水中的溶解度,与没有加入环糊精化合物时相比,这可以使制剂中以更高浓度含有有效成分。这导致的利点是:可以减少为给用有效量的有效成分必需的体积剂量。其结果是,例如,为给用有效量的有效成分,可以将本发明的注射用水性药物制剂作成10mL的一次使用的注射剂。
本发明的水性药物制剂被作成使用时溶解型制剂时,通过与上面同样的方式制备含有所有成分的溶液,如上所述进行灭菌,并根据常用的方法制成粉末或颗粒。作为从溶液制粉末或颗粒的方法,可以使用本身已知的方法:例如,优选使用冷冻干燥和减压干燥。其中,更优选使用冷冻干燥。
作为本发明的注射用水性药物制剂,可以更具体地举出,静脉注射剂、动脉内注射剂、皮下注射剂、皮内注射剂、肌内注射剂、脊髓内注射剂、腹膜内注射剂等。
对于本发明的注射用水性药物制剂的给用方法没有限制,可以通过根据病人年龄、性别、和其它条件、疾病的程度等对病人合适的方法给用。它们可以通过,例如,单独地静脉内、动脉内、肌肉、皮内、皮下、脊髓内或腹膜内给用。另外,本发明的注射用水性药物制剂可以与输液混合,以本发明的注射用水性药物制剂与输液的混合物的形式特别级静脉内给用。对可以使用的输液没有特别的限制,可以使用从商业上可以得到的那些。作为这样的输液的具体例子,可以举出葡萄糖注射液、木糖醇注射液、D-甘露醇注射液、果糖注射液、生理盐水、葡聚糖40注射液、葡聚糖70注射液、氨基酸注射液、林格氏溶液、乳酸-林格氏溶液等。
本发明的注射用水性药物制剂的给用量根据用法、患者的年龄、性别及其它条件、疾病的程度等适当选择。通常,优选选择西洛他唑或其可药用盐的量为约1μg~100mg/1kg体重这样的日剂量。
本发明的注射用水性药物制剂具有血小板凝集抑制作用、磷酸二酯酶(PDE)抑制作用、抗溃疡作用、降压作用及消炎作用,可以用作,例如,抗血栓药、脑血管扩张剂、消炎药、抗溃疡药、降压药、抗哮喘药或磷酸二酯酶抑制药。本发明的注射用水性药物制剂也可以用作慢性闭塞性肺病(COPD)的治疗剂。
