    • PURPOSE: An arrhythmic treatment material having a pH independent elution form is provided to maintain the dronedaron in a molten state or very fine particle even when the condition changes from acid to basic, thereby improving lower bio-availability of salt or the dronedaron. CONSTITUTION: An arrhythmic treatment material having a pH independent elution form comprises an ethylene glycol / vinyl caprolactam / vinyl acetate graft polymer and dronedaron or pharmaceutically-acceptable salt thereof. The dronedaron and the ethylene glycol / vinyl caprolactam / vinyl acetate graft polymer are contained at a weight ratio of 1:0.1-1:5 based on 1 part by weight of the dronedaron. The solid dispersion or the solid liquid having a coprecipitate form contains the ethylene glycol / vinyl caprolactam / vinyl acetate graft polymer and dronedaron or the pharmaceutically-acceptable salt thereof. The solid dispersion or the solid liquid having a coprecipitate form contains the dronedaron and the ethylene glycol / vinyl caprolactam / vinyl acetate graft polymer at a weight ratio of 1:0.1-1:5 based on 1 part by weight of the dronedaron. The dronedaron or the pharmaceutically allowable salt within the ethylene glycol / vinyl caprolactam / vinyl acetate graft polymer is contained in a dispersion form. A manufacturing method of the dronedaron contained solid dispersion or the solid liquid comprises the following steps: melting the dronedaron or the salt which is pharmaceutically allowable and the ethylene glycol / vinyl caprolactam / vinyl acetate graft polymer in an organic solvent; and removing the organic solvent by freeze-drying, figure forming drying, compression drying or spray drying.
    • 目的:提供具有pH独立洗脱形式的心律失常治疗材料,以使即使条件从酸变为碱性,从而改善盐或降糖剂的较低的生物利用度,也可将维生素d维持在熔融状态或极细颗粒。 构成:具有pH独立洗脱形式的心律失常治疗材料包括乙二醇/乙烯基己内酰胺/乙酸乙烯酯接枝聚合物和dronedaron或其药学上可接受的盐。 以1重量份的dronedaron为单位,重量比为1:0.1-1:5,含有癸二醛和乙二醇/乙烯基己内酰胺/乙酸乙烯酯接枝聚合物。 具有共沉淀物形式的固体分散体或固体液体含有乙二醇/乙烯基己内酰胺/乙酸乙烯基酯接枝聚合物和dronedaron或其药学上可接受的盐。 具有共沉淀物形式的固体分散体或固体液体以1重量份的dronedaron为单位含有重量比为1:0.1-1:5的倍他龙和乙二醇/乙烯基己内酰胺/乙酸乙烯酯接枝聚合物。 乙二醇/乙烯基己内酰胺/乙酸乙烯酯接枝聚合物内的dronedaron或药学上允许的盐以分散形式包含。 含有固体分散体或固体液体的制造方法包括以下步骤:将有机溶剂中的丹参酮或其药学上允许的盐和乙二醇/乙烯基己内酰胺/乙酸乙烯酯接枝聚合物熔融; 并通过冷冻干燥,图形干燥,压缩干燥或喷雾干燥除去有机溶剂。
