Problems solved by technology

[0005] A disadvantage of rosuvastatin calcium is that it degrades easily under certain conditions, such as higher temperature or higher humidity environments, forming the main The products are (3R, 5S) lactone degradation products and oxidation products, which makes it difficult to prepare the product, and the prepared pharmaceutical composition cannot meet the storage period requirements
Although the fluidized bed drying method can speed up the drying speed and reduce the exposure time of the composition particles under hot and humid conditions, the fluidized bed equipment is very expensive, and it also needs to be equipped with a large-scale compressed air system, and the particles are lost during the drying process. bigger
High production costs limit the large-scale popularization and use of this method in China

Abstract

The invention relates to a stable oral pharmaceutical composition, particularly to a pharmaceutical composition comprising rosuvastatin calcium, micropowder silica gel and pharmaceutically-acceptable adjuvants, and a preparation method and an application thereof.

Description

technical field [0001] The present invention relates to a stable pharmaceutical composition, in particular to rosuvastatin calcium: bis[(E)-7-[4-(4-fluorophenyl)-6-isopropyl-2-[formazan A stable pharmaceutical composition of (methylsulfonyl)amino]pyrimidin-5-yl]-(3R,5S)-3,5-dihydroxyhept-6-enoic acid]calcium salt (as shown in formula I). [0002] [0003] Formula I Background technique [0004] Rosuvastatin calcium is a potent 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCoA reductase) inhibitor, which can be used in the treatment of hypercholesterolemia, hyperlipoproteinemia and atherosclerosis It is better than other statins on the market in reducing low-density lipoprotein (LDL-C) and increasing high-density lipoprotein (HDL-C), and it is well tolerated and safe. For "super statin". [0005] One disadvantage of rosuvastatin calcium is that it is easily degraded under certain circumstances, such as in a higher temperature or higher humidity environment, and th...
