Description
本申请是申请号为201780000923.9,申请日为2017年01月23日,发明名称为“一种含有喹啉衍生物或其盐的药物组合物”的中国专利申请的分案申请。
技术领域
本发明属于药物制剂领域,具体涉及一种含有(R,E)-N-(4-(3-氯-4-(吡啶-2-基甲氧基)苯基氨基)-3-氰基-7-乙氧基喹啉-6-基)-3-(1-甲基吡咯烷基-2-基)-丙烯酰胺的或其药理学上可接受的盐的药物组合物,该组合物具有溶出迅速的特点。
背景技术
CN102471312B公开了一种小分子化合物(R,E)-N-(4-(3-氯-4-(吡啶-2-基甲氧基)苯基氨基)-3-氰基-7-乙氧基喹啉-6-基)-3-(1-甲基吡咯烷基-2-基)-丙烯酰胺,该化合物具有式I所示的结构,
已知其为小分子受体酪氨酸激酶抑制剂,抑制表皮生长因子受体(EGFR)和人表皮因子受体2(ERBB2)。其可以与细胞内EGFR和ERBB2的激酶区的ATP结合位点共价结合,阻止肿瘤细胞内EGFR和ERBB2的同质和异质二聚体形成,抑制其自身的磷酸化,阻断下游信号通路的激活,从而抑制肿瘤细胞生长。临床上可用于胃癌、肺癌、乳腺癌等多种肿瘤的治疗。
CN102933574B公开了式I化合物的马来酸盐形式,其相对于其他盐和式I化合物本身在溶解度以及生物利用度和药代动力学方面更具优势。
CN103974949B公开了式I化合物二马来酸盐的I型结晶。该晶型具有良好的晶型稳定性和化学稳定性,可用于制备治疗与EGFR受体酪氨酸激酶或HER-2受体酪氨酸激酶有关的疾病的药物。
但是,在将(R,E)-N-(4-(3-氯-4-(吡啶-2-基甲氧基)苯基氨基)-3-氰基-7-乙氧基喹啉-6-基)-3-(1-甲基吡咯烷基-2-基)-丙烯酰胺或其药学上可接受的盐制备成药物固体组合物时,由于活性成分溶解于水后在局部产生较大的粘性,不利于制成药物制剂,同时也造成了药物溶出度下降。
发明内容
本发明的目的在于提供一种溶出迅速的药物组合物,并且该药物组合物制备工艺简单,更适合工艺化大生产。
本发明提供的药物组合物包括活性药物成分和交联聚乙烯吡咯烷酮。活性药物成分为(R,E)-N-(4-(3-氯-4-(吡啶-2-基甲氧基)苯基氨基)-3-氰基-7-乙氧基喹啉-6-基)-3-(1-甲基吡咯烷基-2-基)-丙烯酰胺的或其药理学上可接受的盐,例如盐酸盐、马来酸盐、氢溴酸盐、对甲苯磺酸盐、甲磺酸盐、硫酸盐或乙磺酸盐,优选马来酸盐,更优选二马来酸盐。基于组合物的总重量,所述活性成分的含量范围可以是基于组合物总重量剂计5-70%,优选10-50%,更优选20-40%。交联聚乙烯吡咯烷酮的含量范围可以是基于组合物的总重量约2-20%;优选4-15%;更优选6-10%。
本发明提供的药物组合物还可以含有填充剂,例如微晶纤维素、磷酸氢钙、甘露醇、预胶化淀粉、乳糖等中的一种或多种。基于组合物的总重量,所述填充剂含量为约5-80%。
本发明提供药物组合物还可以含有粘合剂,例如羟丙甲纤维素、羟丙基纤维素、羧甲基纤维素钠、聚乙烯吡咯烷酮、甲基纤维素等中的一种或多种,基于组合物的总重量,所述粘合剂含量为约0.5-15%。
本发明提供药物组合物还可以含有其他崩解剂,例如交联羧甲基纤维素钠、羧甲基淀粉钠、淀粉、低取代羟丙基纤维素等中的一种或多种,基于组合物的总重量,所述崩解剂含量为约0-20%。
本发明提供的药物组合物还可包含一种或多种润滑剂,有助于灌装胶囊或压片。润滑剂包括滑石粉、硬脂酸镁、硬脂酸锌、山嵛酸甘油酯、月桂基硫酸钠、氢化植物油、胶体二氧化硅等。基于组合物的总重量,润滑剂的含量为约0.5-5%。
本发明还提供了一种药物组合物,包括:
1)5-70wt%的(R,E)-N-(4-(3-氯-4-(吡啶-2-基甲氧基)苯基氨基)-3-氰基-7-乙氧基喹啉-6-基)-3-(1-甲基吡咯烷基-2-基)-丙烯酰胺或其药理学上可接受的盐;
2)2-20wt%的交联聚乙烯吡咯烷酮;
3)5-80wt%的填充剂,所述填充剂选自乳糖和微晶纤维素中的一种或多种;
4)0.5-15wt%的粘合剂,所述粘合剂选自聚乙烯吡咯烷酮、羟丙基甲基纤维素及羟丙基纤维素中的一种或多种;
5)0.5-5wt%的润滑剂,所述润滑剂选自硬脂酸镁和滑石粉的一种或多种。
在溶出实验中可以看出,本发明的药物组合物由于加入了交联聚乙烯吡咯烷酮,使得活性药物的溶出度大大提升,溶出迅速且完全,有利于药物进入体内迅速起效,发挥药效。
本发明还提供了一种药物组合物,在制备药物组合物的过程中可加入润湿剂,所述润湿剂可包含至少一种有机溶剂,还可包含水,其中有机溶剂可以是低毒性的有机溶剂,优选乙醇、丙酮等,更优选乙醇。基于润湿剂的总重量,所述有机溶剂的含量可以是20~100%,优选50~95%,更优选50~80%。
由于在制备药物组合物的过程中加入的润湿剂包含了乙醇等低毒性有机溶剂,使得制备出的颗粒粒径分布较理想,活性药物溶出迅速完全,便于药物发挥药效。
本发明的药物组合物溶出迅速,起效显著,可用于胃癌、肺癌或乳腺癌等癌症的治疗。
本发明还提供了一种制备药物组合物的方法,包括混合(R,E)-N-(4-(3-氯-4-(吡啶-2-基甲氧基)苯基氨基)-3-氰基-7-乙氧基喹啉-6-基)-3-(1-甲基吡咯烷基-2-基)-丙烯酰胺或其药理学上可接受的盐以及交联聚乙烯吡咯烷酮,可采用本领域常见的方法制备成颗粒,例如湿法制粒,最终制备成片剂、胶囊剂等口服制剂。
