Abstract

The invention relates to a tablet composition containing ezetimibe and atorvastatin calcium and a preparation method of the composition. According to the method, the stability of atorvastatin calcium in a pharmaceutical composition can be effectively improved, and the in-vivo bioavailability of the medicine is improved. Moreover, the method has the advantages that the process is simple and feasible to operate, the requirement on preparation equipment is low, and the production cost is reduced. The solid oral preparation is used for treating or preventing cardiovascular and cerebrovascular diseases.

Description

technical field [0001] The invention relates to a tablet for treating dyslipidemia, in particular to its prescription composition and preparation process, and belongs to the technical field of medicine. Background technique [0002] Coronary heart disease (CHD) is an important cause of disability and death in developed and developing countries, and it is also the main cause of late heart failure. Dyslipidemia has been recognized as a risk factor for cardiovascular disease and is one of the main risk factors for coronary heart disease. Low density lipoprotein cholesterol (LDL-C) is the most important pathogenic factor of CHD, and its plasma concentration Elevation was positively correlated with the risk of coronary heart disease. For high-risk groups with CHD and its equivalent risk diseases (diabetes), the optimal lipid-lowering target should be LDL-C ≤ 2.6mmol L-1, and for extremely high-risk groups (such as CHD complicated with diabetes, acute coronary syndrome) should be...
