Description

一种不含防腐剂的固体剂型氨己烯酸药物组合物 技术领域
该发明涉及一个新型不含防腐剂的药物组合物,可复溶成溶液并多次使用。
背景技术
氨己烯酸是在美国的上市产品,商品名为
Figure PCTCN2019090465-appb-000001
由灵北制药公司研发用于治疗顽固性复杂性部分发作癫痫和婴儿痉挛症。
Figure PCTCN2019090465-appb-000002
目前在市场上只有两种剂型,口服片剂和散剂。由于儿童和婴幼儿的患者人群的特点,需要调节给药剂量,因此仅散剂可用于这部分人群患者。然而
Figure PCTCN2019090465-appb-000003
散剂在服用前,需要用水配制成溶液,并且该药液是一次性使用。这可能导致给药错误,剂量浪费,或由于非医疗专业人员(例如患者和监护人)配制错误药液浓度而给予不正确的剂量。给予错误剂量的氨己烯酸可能是致命的,因其可能导致视力损害,该上市药品需要采取REMS风控计划。考虑到经济和安全的原因,剂量浪费也需要引起重点关注,一些患者可能将未使用的粉末或溶液储存以备将来使用,这是目前批准的标签所不支持的。
Vigabatrin是一种氨基酸,在酸性或碱性环境下不稳定。在大多数可多次使用的口服溶液中,会添加防腐剂以抑制微生物生长和污染以及生物降解,并确保药物产品安全有效。虽然防腐剂在口服液多次使用过程中可保持容器或包装无菌,然而,它们可能诱导或增加某些个体的不良反应,尤其是在儿科和婴儿中使用。
发明内容
本发明涉及的多剂量,即用型的氨己烯酸产品降低了给药剂量错误的风险并改善了患者的依从性。此外,该发明对于需要长期治疗的癫痫患者,无防腐剂的可多次使用的药物递送系统是绝佳的选择。
本发明涉及一种无防腐剂,可复溶成口服溶液的氨己烯酸固体剂型。该剂型和其溶液基本不含例如对羟基苯甲酸酯,山梨酸钾,苯甲酸钠,有机溶剂或其它的常用于稳定药物,可耐受,同时保持药物功效防腐剂体系。意想不到的是,不含任何防腐剂的该氨己烯酸溶液,在较长时间内无超限的降解和或者微生物生长或污染,可多次使用。
本发明包括不含防腐剂的氨己烯酸口服溶液用粉末,其复溶的溶液为无色透明,口感良好。所得溶液在合适的pH范围和所需的浓度范围内,可以多次使用。
这个固体剂型或者组合物盛装在合适的容器内,其用于将所述固体剂型或组合物制备溶液的工具也包含在本发明的范围内。同时,该工具也可用于给药和药物处理及治疗。
本发明的另一个目的是提供了可制备溶液的稳定干混粉末或颗粒,所制得的溶液包含氨己烯酸或其药学上等同的衍生物,该溶液具有良好化学稳定性的。
本发明还提供了治疗CNS疾病的方法,其包括向有需要的受试者服用由本文所述的固体剂型组合物复溶的溶液。
详细的发明

该固体剂型组合物可含有适用于本发明的任何药学上可接受的辅料。在一些实施方案中,组合物包含糖和糖醇中的至少一种,和可选的其他组分如缓冲剂,甜味剂和香精。在一些实施方案中,固体剂型组合物为粉末形式。
糖和糖醇是指但不限于蔗糖,乳糖,果糖,葡萄糖,甘露醇,山梨醇和木糖醇中的一种或多种。该组合物可为含有糖和/或糖醇的任何组合。根据本发明的糖和/或糖醇还可以在用作可复溶成口服溶液的固体剂型组合物的甜味剂。基于固体剂型组合物的总重量, 本发明中固体剂型组合物中使用的糖和/或糖醇的量范围从约占10%至99%w/w。在一些实施方案中,固体剂型组合物中使用的糖和/或糖醇量占组合物的总重量的范围从约20%至约99%,或从约30%至约99%,或从约40%至约99%,或从约50%至约99%,或从约60%至约99%,或从约70%至约99%,或从约80%至约99%,或从约60%至约90%,或从约60%至约80%。
可在该组合物中加入缓冲剂。合适的缓冲剂的实例包括但不限于:柠檬酸钠,柠檬酸,富马酸,酒石酸,柠檬酸钾,碳酸氢钠,碳酸氢钾,磷酸二氢钠,磷酸氢二钠,氢氧化钠和磷酸二氢钾。当使用来自具有不同pH范围的不同来源的水复溶粉末成口服溶液时,缓冲剂应具有足够的缓冲能力以确保复溶的溶液仍在预期的pH范围内。复溶后的缓冲液浓度范围约为10mM至200mM,优选10mM至50mM。
甜味剂可包括例如蔗糖,葡萄糖,山梨醇,三氯蔗糖,阿斯巴甜,糖精钠和任何其他药学上可接受的甜味剂或任意其他组合。用于口服溶液组合物的粉末中的甜味剂的量通常为口服溶液粉末总重量的约0.1%至约99%,优选0.1%-10%w/w。在一些示例性实施方案中,甜味剂是蔗糖,葡萄糖,山梨醇,三氯蔗糖,阿斯巴甜,糖精钠,任何其他药学上可接受的甜味剂或其任意组合。
矫味剂可选自,例如,石榴香精,浆果香精,草莓香精,香蕉香精,橙味和薄荷香精。口服溶液用粉末中的香精量占口服溶液用粉末的总重量为约0.1%至约5%w/w。
前述列表中具体提及的合适的糖,糖醇,缓冲剂,甜味剂和矫味剂旨在阐述可用于实施本发明的具体辅料的示例,而非穷举性的。还应进一步理解,任何特定类型的辅料中,其可能不止一种用于本文所述的可复溶成口服溶液的组合物粉末中。例如,组合物可包含一种以上的糖,甜味剂等。此外,单一辅料也可能具有多种功能。
本文还提供了含有本发明所述固体剂型组合物的装置或工具包。该装置或工具包含有复溶组合物和如何给药的说明。
可复溶成口服溶液的固体剂型可通过本领域已知的一般方法制备。实例包括干粉混合,湿法制粒,干法制粒,喷雾干燥,热熔挤出,挤出滚圆和流化床造粒。
本发明的另一方面提供了由本文所述的固体剂型组合物复溶的口服溶液。通常,可复溶成口服溶液的固体剂型组合物在复溶于溶质(例如水)之前储存在合适的容器中。该溶液可以由药剂师根据固体剂型组合物的说明书制备。在一个示例性实施方案中,通过向装有粉末的瓶子中加入准确量的水,然后摇动瓶子以使水与粉末混合直至所有固体已经溶解来制备溶液。因此,不含防腐剂的该口服溶液就是患者可多次使用的实际剂型。 口服给药注射器可根据处方吸取合适的药液量来给予病人。
在将固体剂型的组合物复溶成口服溶液后,该溶液可为接受治疗的受试者提供便利和准确的剂量滴定,包括例如婴幼儿患者和由于吞咽困难而不能吞咽片剂的患者。
在一些实施方案中,固体剂型的组合物用水复溶后用于口服溶液为每约10ml液体含有约500mg药物的溶液。固体剂型的组合物在储存时是稳定的,并且当用水复溶后给药时,相应的液体溶液在治疗期间使用时也是稳定的。在一些实施方案中,溶液中的药物浓度高于约10mg/ml。在一些实施方案中,溶液中的药物浓度为约10至约100mg/ml,约20至约100mg/ml,约30至约100mg/ml,约40至约100mg/ml,约40至约90mg/ml,约40至约80mg/ml,约40至约70mg/ml,或约40至约60mg/ml。
溶液的pH范围为约5.0至约8.0。在一些实施方案中,溶液的pH范围为约5.5至约7.5,约6.0至约7.5或约6.0至约7.0。
溶液中糖和/或糖醇的含量为40-80%(重量比)。在一些实施方案中,溶液中糖和/或糖醇的重量比为约50%至约70%,约55%至约65%,或约60%至约70%重量。
该溶液可多次使用。在多次使用的整个期间,溶液的质量仍在质量标准范围内。在一些实施方案中,由本文所述的固体组合物制备的溶液在其第二,第三,第五,第十,第十一,第十四,第二十,第三十,第四十,第五十,六十,八十或第九十天的可通过在USP<51>项下抑菌试验测试(AET)。溶液中的药物在多次使用的整个期间仍能保持其功效,其中至少约70%,至少约80%,至少约85%,至少约90%,至少约95%或,至少约98%的药物保持稳定或未分解。在一些实施方案中,该药物是氨己烯酸。
本发明的另一方面提供治疗中枢神经系统(CNS)疾病的方法,包括向有需要的受试者施用本文所述的口服溶液。该溶液给药间隔至少约30分钟,至少约1小时,至少约5小时,至少约10小时,至少24小时,至少2天,至少5天,至少7天,至少15天,至少20天,至少30天,至少50天,至少60天,或上述间隔的任何组合。例如,在初次给药后,第二次给予部分该溶液可以在8小时内给药,第三次给予部分该溶液可以在第二次给药后24小时内给药。随后的部分该口服溶液可以以合适的间隔进行给药。在一些实施方案中,间隔至少为1周。在一些实施方案中,间隔为约1周至约3个月,约1周至约2个月或约2周至约2个月。每个单独部分的剂量可以由本领域普通技术人员根据有此需要的受试者的具体疾病状况来确定。当然,组合物的容器或装置上的说明也会为患者提供指导以给予适当量的溶液。在一些实施方案中,CNS疾病可为婴儿痉挛症,复杂难治性癫痫发作,妥瑞氏综合征,难治性自身免疫性脑炎,可卡因依赖性,结 节性硬化症引起的婴儿痉挛症。
具体实施方式
提供以下实施例是为了使本领域技术人员能够实施本发明,并且仅是对本发明的说明。这些实施例不应理解为限制本发明中权利要求所定义的范围。
如下表1中所述制备不含防腐剂的粉末组合物,用于制备口服溶液
表1 250ml瓶装用于制备口服溶液的粉末组合物处方
成分 g/250ml %(w/w) 功能
氨己烯酸 12.5 5.6% 活性成分
蔗糖 212.5 94.4% 填充剂/甜味剂
将112.5g水加入到瓶中的粉末,制成250ml溶液。剧烈摇动瓶子直至所有固体溶解并形成浓度为50mg/ml的无色透明溶液。
以单一的API作为对照,按照USP<51>要求对复溶的API溶液和API+蔗糖溶液进行了抑菌试验测试(AET)。在两个不同的瓶子上对每种溶液都进行测试。
在不同的瓶子复溶的API+蔗糖溶液全部通过AET测试,而单一的API溶液在14天时未通过测试,因为B.cepacian不符合要求。结果显示在表2和表3中
