    • PROBLEM TO BE SOLVED: To providea method for manufacturing a highly drug elution-controlled particulate preparation, which can simply manufacture the particulate preparation by multilayer-coating drug particles through a spray-drying technique without using such a complicated method as simultaneous spraying of two different spray liquids from different nozzles.SOLUTION: The method for manufacturing the particulate preparation includes : a step of forming a first coating layer on drug particles through a spray-drying technique after dissolving and/or suspending the drug particles in a first coating solution containing a cellulose-based enteric polymer; and a step of forming a second coating layer on the drug particles through the splay-drying technique after suspending the drug particles in a second coating solution containing a water-insoluble polymer different from the cellulose-based enteric polymer.
    • 解决问题的方案:提供一种制备高药物洗脱控制的颗粒制剂的方法,其可以通过喷雾干燥技术多次涂覆药物颗粒来简单地制备颗粒制剂,而不使用如同时喷雾的这种复杂的方法 来自不同喷嘴的两种不同喷雾液体。 解决方案:制备颗粒制剂的方法包括:通过喷雾干燥技术在将药物颗粒溶解和/或悬浮在含有纤维素基的第一涂层溶液中之后在药物颗粒上形成第一涂层的步骤 肠溶性聚合物 以及在将药物颗粒悬浮在含有不同于纤维素类肠溶性聚合物的水不溶性聚合物的第二涂布溶液中之后,通过喷雾干燥技术在药物颗粒上形成第二涂层的步骤。 版权所有(C)2013,JPO&INPIT
