根据本发明的具体实施例,所述制备阿哌沙班组合物的方法进一步包括:将填充剂、崩解剂和表面活性剂加入高剪切湿法制粒机中并进行预混处理;向预混处理后产物中喷射所述粘合剂溶液,以便获得湿颗粒;将所述湿颗粒加入流化床中进行干燥处理,以便获得干颗粒;将所述干颗粒进行整粒处理;以及向整粒后所得颗粒中加入润滑剂并进行总混处理。发明人发现,利用上述制备阿哌沙班组合物的工艺,相比于干法制粒工艺,所得产品具有更快的溶出速率及更高的溶出度,产品质量提高。
根据本发明的再一具体实施例,所述喷射是在喷液速度为5~60g/min的条件下进行的。发明人发现,喷液速度高于60g/min,加液过快,在粘合剂的作用下,物料易结块,干燥后粗颗粒偏多,可压性会变差,同时成品的含量均匀度也会受影响;而喷液速度低于5g/min,加液过慢,物料的润湿性受影响,从而制得颗粒细粉会偏多,可压性会变差,成品的含量均匀度也会受影响,同时,喷液速度过慢,加液时间会延长,影响生产效率。因此将喷液速度控制在5~60g/min,可进一步提高成粒性、可压性,制粒效率也会进一步提高。
根据本发明的具体实施例,所述方法还可以进一步包括对总混处理后产物进行压片和包衣处理。进行压片处理可避免组合物立即与胃肠接触而降低药效,进行包衣处理可有效将组合物隔绝空气,防潮避光,产品的稳定性进一步提高。
在本发明的第九方面,本发明提出了一种制备阿哌沙班组合物的方法。根据本发明的实施例,所述方法包括:(1)将阿哌沙班和粘合剂溶于润湿剂,以便获得粘合剂溶液,所述阿哌沙班的粒径D90大于89μm,所述润湿剂为乙酸或DMSO,所述粘合剂为聚维酮所述粘合剂在所述润湿剂中的含量为0.02g/mL-0.5g/mL;(2)将填充剂、崩解剂和表面活性剂加入流化床中并进行预热处理,预热处理后温度为35℃~50℃;(3)向预热处理后产物中喷射所述粘合剂溶液,所述喷射是在雾化压力为0.5-2.0bar,喷液速度为3.0-20.0g/min的条件下进行的,将喷射有所述粘合剂溶液的所述预热处理后产物进行干燥处理,以便获得干颗粒;(4)将所述干颗粒进行整粒处理;(5)向整粒后所得颗粒中加入润滑剂并进行总混处理;以及(6)对总混处理后产物进行压片和包衣处理。利用根据本发明实施例的方法制备阿哌沙班组合物,可大大克服小粒径阿哌沙班对规模生产的限制,更加适合工 业化规模生产,且组合物的颗粒成粒性、可压性更好,压片过程稳定可控,工艺重现性好,工艺更稳定。利用根据本发明实施例的方法制备所得阿哌沙班组合物,具有相比于现有阿哌沙班制剂的更快的溶出速率及更高的溶出度,且产品的稳定性更高的显著优势。
在本发明的第十方面,本发明提出了一种制备阿哌沙班组合物的方法。根据本发明的实施例,所述方法包括:(1)将阿哌沙班和粘合剂溶于润湿剂,以便获得粘合剂溶液,所述阿哌沙班的粒径D90大于89μm,所述润湿剂为乙酸或DMSO,所述粘合剂为聚维酮所述粘合剂在所述润湿剂中的含量为0.02g/mL-0.5g/mL;(2)将填充剂、崩解剂和表面活性剂加入高剪切湿法制粒机中并进行预混处理;(3)向预混处理后产物中喷射所述粘合剂溶液,所述喷射是在喷液速度为5~60g/min的条件下进行的,将喷射有所述粘合剂溶液的预混处理后产物进行制粒处理,所述质粒处理的时间为3~5min,以便获得湿颗粒;(4)将所述湿颗粒加入流化床中进行干燥处理,以便获得干颗粒;(5)将所述干颗粒进行整粒处理;(6)向整粒后所得颗粒中加入润滑剂并进行总混处理;以及(7)对总混处理后产物进行压片和包衣处理。利用根据本发明实施例的方法制备阿哌沙班组合物,可大大克服小粒径阿哌沙班对规模生产的限制,更加适合工业化规模生产,且组合物的颗粒成粒性、可压性更好,压片过程稳定可控,工艺重现性好,工艺更稳定。利用根据本发明实施例的方法制备所得阿哌沙班组合物,具有相比于现有阿哌沙班制剂的更快的溶出速率及更高的溶出度,且产品的稳定性更高的显著优势。

结论:从处方7~11的溶出结果来看,溶出曲线均相似,15min溶出均大于85%,溶出平台正常,均接近100%;因此,当粘合剂在润湿剂中含量为0.02~0.5g/mL范围内时,产品溶出快且溶出平台正常,符合质量标准。另外。发明人发现,当粘合剂在湿润剂中的浓度低于0.02g/mL时,粘合剂溶液用量过大,制粒时间明显延长,耗时耗能,不适合工业化大生产,但粘合剂浓度低于0.02g/mL并不影响所得产品的质量;当粘合剂浓度高于0.5g/mL时,受限于粘合剂,如聚维酮PVP的溶解度,此时部分粘合剂如PVP未溶解呈混悬状态。
实施例4API粒径的考察
1、API粒径对物料成本影响的考察
本申请所要求保护的阿哌沙班的固体组合物中的活性成份采用的是粒径D90大于89μm的阿哌沙班。而如果采用粒径D90小于或等于89μm的阿哌沙班制备阿哌沙班固体组合物,需要对阿哌沙班原料药进行粉碎,此时物料成本就会大幅增加,具体体现在:首先,需要采购粉碎机,一般选择万能粉碎机,其造价昂贵;如果要得到粒径非常小(如小于等于10μm)的原料药,则需要采购气流粉碎机进行微粉化,造价更昂贵。其次,粉碎工序对原料药的损耗较大,其收率一般在80%~90%之间,且粉碎后需要取样全检放行并同时考察稳定性,则需要消耗更多的原料药,因此会极大的增加生产成本;再次,粉碎工序需要消耗大量水、电、气,能耗过高,同时还需要多人操作,安装设备、清洗设备也需要大量时间,因此,需要更多的人力以及物力。最后,粉碎后的原料药一般容易结块,必须现粉现用,因此,不利于商业化的连续性生产。表8中列出了将不同粒径API粉碎时的损耗率:
表8:

360 58 万能粉碎机 10%
360 8 气流粉碎机粉碎机 18%
150 30 万能粉碎机 13%
150 4 气流粉碎机粉碎机 20%
每生产一批注册批产品需消耗原料药阿哌沙班2.88kg,生产药品时若使用粒径在10-89μm之间的原料药,则需先用万能粉碎机粉碎,原料药损耗率至少为10%,故至少需多预算0.32kg;又因为粉碎步骤中需取样进行检测,并适当留样,故又需多预算0.1kg~0.5kg(每次粉碎1-5批的用量,每次粉碎取样留样量为0.5kg),如果算上粉碎过程的能耗以及人耗,则原料药成本至少会增加17%~31%,还不算设备折旧费。同理可证,如果使用粒径小于10μm的原料药,则原料药成本更会陡增28%~42%。由此 可见,采用粒径D90大于89μm的阿哌沙班原料药进行制粒具有极大的成本优势。
2、API粒径对溶出速率影响的考察
在本实施例中,发明人在聚维酮/冰乙酸的用量为0.2g/mL的条件下,考察了不同粒径API对制剂的溶出速率的影响。
表9:处方2、3、6、8、12和13的API粒径、润湿剂及制粒工艺
Figure PCTCN2017070911-appb-000006
处方12和13的制备过程如下所述:
(1)配料:按照表1所示处方量,精密称定;
(2)粘合剂配制:按表9所示聚维酮/冰乙酸的用量量取冰乙酸,然后将称量好的阿哌沙班、聚维酮溶入冰乙酸中,搅拌至均匀的溶液,备用;
后续步骤同处方2制备方法中的步骤(3)-(7)或者同处方3制备方法中的步骤(3)-(8)。
溶出条件同实施例1,
其中,表10显示了处方2、3、6、8、12和13的溶出曲线(%),

由表10可以看出,在API粒径D90大于89μm的前提下,不管采用湿法制粒还是 流化床制粒工艺,成品溶出速率均达到快速溶出,溶出平台均接近100%。
实施例5稳定性考察
在本实施例中,发明人考察了利用本发明实施例的制备方法所得的阿哌沙班组合物的稳定性。具体方法如下所述:
