Description
本申请是中国专利申请号为2019800027541,发明名称为“包含第三代小分子EGFR抑制剂的药物组合物及其制备方法”,申请日为2019年5月13日的进入中国的PCT专利申请的分案申请。
技术领域
本发明属于药物制剂领域,具体涉及一种包含第三代小分子EGFR抑制剂的药物组合物及其制备方法。
背景技术
EGFR(Epidermal Growth Factor Receptor)是跨膜蛋白酪氨酸激酶erbB受体家族的一员。通过与其配体-例如表皮生长因子(EGF)的结合,EGFR在细胞膜上可以形成同源二聚体,或者与家族中其他的受体(比如erbB2,erbB3,或erbB4)形成异源二聚体。这些二聚体的形成,可引起EGFR细胞内关键的酪氨酸残基磷酸化,从而激活细胞内多个下游的信号通路。这些细胞内信号通路在细胞增殖、生存及抗凋亡中起重要作用。EGFR信号传导通路失调,包括配体及受体的表达增高、EGFR基因扩增以及突变等,可促进细胞向恶性转化,并在肿瘤细胞的增殖、侵袭、转移以及血管形成中起重要作用。因此,EGFR是抗癌药物开发的合理靶点。

发明人通过大量的研究发现,N-(5-((4-(1-环丙基-1H-吲哚-3-基)嘧啶-2-基)氨基)-2-((2-(二甲氨基)乙基)(甲基)氨基)-4-甲氧苯基)丙烯酰胺作为第三代小分子EGFR化合物,其溶解度受pH影响较大,具有pH依赖性,为低渗透性药物。而本发明制备的药物组合物,在不同的溶出介质下均有很好的溶出,并且溶出一致。
具体实施方式
关于填充剂:
通过表1可以发现,当填充剂包含乳糖时,可制备得到高含量的式I化合物的药物组合物,同时得到的药物组合物可压性好。
表1填充剂筛选
1注:活性成分以甲磺酸盐计,下同。
进一步提高片剂中活性成分的载药量,当活性成分的含量为43.3%时,片剂仍具有非常好的可压性,制备得到的素片光洁,无粘冲现象,已制备片剂形状完整、外观良好,合格率为100%。
表2填充剂种类及用量
此外,素片的硬度也是影响溶出度的因素之一,硬度不均可能导致溶出不均匀进而影响药效,下表3给出了本发明处方在不同硬度时对应的溶出度情况,对比表中内容可知,本发明处方在不同素片硬度条件下能够消除素片硬度变化对溶出结果的影响,使产品保持良好的溶出度,因此,本发明处方可以解决不同素片硬度带来的不利影响。
表3本发明处方在不同硬度下的溶出度检测
关于崩解剂:
在本发明药物组合物体系中,崩解剂的添加同样会影响片剂的溶出度,发明人发现,崩解剂的用量在1-30%的范围内时溶出度优良,具体参见表4,当选择羧甲淀粉钠作为崩解剂时,能够保证片剂良好的崩解和制备,优选的用量为10%~20%。
