Problems solved by technology

[0005] Rosuvastatin calcium also has defects. For example, it is easily degraded in a higher temperature or higher humidity environment, and the main products formed are (3R, 5S) lactone degradation products and oxidation products, which makes the preparation of products difficult to operate, and The prepared pharmaceutical composition does not meet the storage period requirements
However, the addition of a large amount of alkaline agent is not conducive to the formulation of the pharmaceutical composition. After entering the body, the alkaline agent may also cause a variety of unexpected side effects, and may even lead to a decrease in bioavailability.

Abstract

The invention discloses a solid preparation containing rosuvastain calcium liposome and particularly relates to the solid preparation containing rosuvastain calcium liposome and a preparation method thereof. The rosuvastain calcium liposome mainly comprises 1 part of rosuvastain calcium, 2-25 parts of soyabean lecithin, 0.5-10 parts of cholesterol, 0.5-12 parts of tween 80 and 0.05-10 parts of sodium desoxycholate. The rosuvastain calcium solid preparation prepared from the liposome not only increases the dissolution, but also improves the stability and the bioavilability. The quality of preparation products is improved and the toxic or side effects are reduced.

Description

technical field [0001] The invention relates to a rosuvastatin calcium liposome solid preparation and a preparation method thereof, in particular to an amorphous rosuvastatin calcium liposome solid preparation and a preparation method thereof, belonging to the technical field of medicine. Background technique [0002] Cardiovascular disease is a kind of disease that seriously endangers human health. In recent years, its morbidity and mortality have remained high all over the world, and it is currently the number one killer of human beings. According to the statistics of the World Health Organization, about 15 million people die of cardiovascular and cerebrovascular diseases in the world every year. With the improvement of people's living standards in my country, the growth of the elderly population (the elderly population over 60 years old has accounted for 10.7% of the national population at present, reaching as many as 130 million). With the accelerated pace of life, eati...
