    • PURPOSE: A method for manufacturing a sustained release granule containing theobromine is provided to effectively relieve or treat cough by administering once a day. CONSTITUTION: A sustained release granule of theobromine comprises a water insoluble polymer, an inner layer formed of lubricant, and an external layer formed of hydrophilic polymers and pharmaceutically acceptable additives. A method for manufacturing the granule comprises: a step of inputting 800 weight parts of theobromine powder into a coating device; a step of spraying a primary coating solution containing 100-200 weight parts of water insoluble polymers, 8-16 weight parts of lubricant, and 1700-3200 weight parts of dispersion solvent to coat the inner layer; and a step of spraying a secondary coating solution containing 30-50 weight parts of hydrophilic polymers, 1500-1700 weight parts of pharmaceutically acceptable additives, and 600-700 weight parts of dispersion solvent to coat the external layer.
    • 目的:提供含有可可碱的持续释放颗粒的制备方法,通过每天施用一次以有效缓解或治疗咳嗽。 构成:可可碱的缓释颗粒包括水不溶性聚合物,由润滑剂形成的内层,以及由亲水聚合物和药学上可接受的添加剂形成的外层。 一种制造颗粒的方法包括:将800重量份的可可碱粉末输入涂布装置的步骤; 喷涂含有100-200重量份水不溶性聚合物,8-16重量份润滑剂和1700-3200重量份分散溶剂的初级涂层溶液以涂覆内层的步骤; 以及喷涂含有30-50重量份亲水性聚合物,1500-1700重量份药学上可接受的添加剂和600-700重量份分散溶剂的二次涂布溶液以涂覆外层的步骤。
