发明背景
US专利5,273,975一般性要求了(R)-5,6-二氢-5-(甲基氨基)-4H-咪唑并[4,5-ij]-喹啉-2(1H)-酮(Z)-2-丁烯二酸盐(1∶1),但没有具体公开。其中只是一般性公开了该化合物可用于治疗帕金森氏病。
US专利4,389,393要求了含有少于25.8%的羟丙基甲基纤维素的持续释放药物片剂。羟丙基甲基纤维素已被广泛用于制造持续释放(缓慢崩解)片剂。
US专利5,000,962公开了含有多于35-60%(重量)的羟丙基甲基纤维素和乳糖作为赋形剂的长效片剂。本发明不使用乳糖。
Dow’s 1995 Formulating for Controlled Release With MethocelPremium Cellulose Ethers在第21页图24中公开了使用淀粉和Methocel(羟丙基甲基纤维素)制备含茶碱的片剂。本发明的片剂不含茶碱但是含(R)-5,6-二氢-5-(甲基氨基)-4H-咪唑并[4,5-ij]-喹啉-2(1H)-酮(Z)-2-丁烯二酸盐(1∶1)。在第20页图20中公开了片剂大小和释放百分比与乳糖的关系。一般地,在直接释放片剂中淀粉的用量达到约15-20%。但是在持续释放制剂中不使用,因为考虑到它会加速崩解。Dow公开了使用淀粉(赋形剂)的量为52.6%。本发明片剂中淀粉的用量大于60%。
国际专利公开WO97/34932公开了药物片剂,它含有机械破坏的淀粉,该淀粉可提供延迟释放,控制释放和靶向释放制剂。本发明不使用机械破坏的淀粉。
国际专利公开WO97/37639公开了控释药物片剂,它含有交联直链淀粉和羟丙基甲基纤维素和10-30%的羟丙基甲基纤维素。本发明的片剂不使用交联的直链淀粉且含有30-40%的羟丙基甲基纤维素。
本发明公开了一种药物组合物,它是用于口服的持续释放片剂,它含有:
(a)(R)-5,6-二氢-5-(甲基氨基)-4H-咪唑并
[4,5-ij]-喹啉-2(1H)-酮(Z)-2-丁烯二酸盐(1∶1) 0.3%-16%

优选片剂含有硬脂酸镁,但它不是必须的。如果存在硬脂酸镁,其存在量应在约0.2%至约2.0%。
优选片剂含有胶体二氧化硅,但它不是必须的。如果存在胶体二氧化硅,其存在量应在约0.2%至约1.0%。
正如本领域技术人员已知的,其他添加剂如甜味剂,着色剂,包衣等也可加入片剂。
片剂可通过直接压片法或湿制粒法制备,这两种方法都是本领域技术人员已知的。如果使用直接压片法,先将活性组分(R)-5,6-二氢-5-(甲基氨基)-4H-咪唑并[4,5-ij]-喹啉-2(1H)-酮(Z)-2-丁烯二酸盐(1∶1),淀粉和羟丙基甲基纤维素(和胶体二氧化硅,如果使用的话)分别过筛,然后在合适尺寸的容器或搅拌器内混合。如果使用硬脂酸镁,也先将其过筛然后与容器或搅拌器中的一部分物质混合,然后将所有物质一起充分混合。用本领域技术人员已知的方法将该经润滑混合物压成所需重量和物理规格的药片。
如果使用湿制粒法,使用羟丙基纤维素或聚乙烯吡咯烷酮(PVP)制备粘合剂溶液。将粘合剂溶液喷淋到药物活性组分(R)-5,6-二氢-5-(甲基氨基)-4H-咪唑并[4,5-ij]-喹啉-2(1H)-酮(Z)-2-丁烯二酸盐(1∶1)和一部分除润滑剂(硬脂酸镁)外其他组分的混合物上。湿颗粒应在干燥器如流化床中干燥。然后应将干混合物与润滑剂和其余组分混合形成最终混合物,用本领域技术人员已知的方法将它压成所需重量和物理规格的药片。
(R)-5,6-二氢-5-(甲基氨基)-4H-咪唑并[4,5-ij]-喹啉-2(1H)-酮(Z)-2-丁烯二酸盐(1∶1)用于治疗帕金森氏病。它以片剂或胶囊的形式每天口服给药两次,优选使用片剂。由于帕金森氏病是老年人的疾病,不涉及儿童,药物不用mg/kg表示,而是用每天的量表示。优选(R)-5,6-二氢-5-(甲基氨基)-4H-咪唑并[4,5-ij]-喹啉-2(1H)-酮(Z)-2-丁烯二酸盐(1∶1)的给药量为约2mg-约112mg/天,更优选约3mg-约70mg/天。由于持续释放片剂一天给药两次时足够维持血液水平,因此日剂量优选分两次等量给药。
给药的准确剂量和频率依赖于具体患者的病情严重程度,体重,一般身体条件,以及患者可能服用的其他药物,这些都是本领域技术人员已知的,而且可通过检测血液水平或(R)-5,6-二氢-5-(甲基氨基)-4H-咪唑并[4,5-ij]-喹啉-2(1H)-酮(Z)-2-丁烯二酸盐(1∶1)的游离碱在患者血中的浓度和/或患者对具体处理的应答而更准确地确定。
