Abstract

The invention relates to a rosuvastatin calcium sustained-release preparation and a preparation method thereof. The rosuvastatin calcium sustained-release preparation basically contains 5 to 10mg of rosuvastatin calcium, and the balance of sustained-release framework material and other pharmaceutical excipients. The preparation method is simple; and all the materials are proportioned and the preparation is prepared by the preparation method for common tablets, granules or capsules. The rosuvastatin calcium sustained-release preparation prepared by the method avoids adverse reactions such as rhabdomyolysis, proteinuria, nephrosis, kidney failure, hepatotoxicity and the like caused by overdosage of medicaments; meanwhile, due blood concentration and time for treating diseases after the medicaments are taken can be maintained, and the peak valley phenomenon of the blood concentration is effectively avoided.

Description

technical field [0001] The invention relates to a drug sustained-release preparation, in particular to a sustained-release preparation of rosuvastatin calcium and a preparation method thereof. Background technique [0002] In recent years, diseases of the cardiovascular system have ranked among the top three causes of death in my country. Atherosclerosis is the main pathological basis of cardiovascular and cerebrovascular diseases. Prevention and treatment of atherosclerosis is an important measure to prevent and treat cardiovascular and cerebrovascular diseases. Some blood lipids or lipoproteins are higher than the normal range and become hyperlipidemia. It is generally believed that hyperlipidemia can promote the formation and development of atherosclerotic lesions. Epidemiological survey The plasma levels of total cholesterol (TC) and low-density lipoprotein (LDL) are closely related to the morbidity and mortality of coronary heart disease and cerebrovascular disease. Th...
