Abstract

The invention provides a new osmotic pump controlled release pharmaceutical composition used for treating hyperlipoidemia and a preparation method thereof, the pharmaceutical composition has a nicotinic acids medicine such as acipimox and the other one estatina medicine such as simvastatin; wherein, the nicotinic acids medicine such as acipimox is a controlled release part, and the estatina medicine such as simvastatin is a quick release part; or both the acipimox and the simvastatin are the controlled release part. The compound osmotic pump preparation of the invention has the advantages of comprehensive action, low toxicity and side effects and convenient use.

Description

technical field [0001] The invention belongs to the field of medicine, and relates to an osmotic pump controlled-release preparation containing niacin and a statin and a preparation method thereof, in particular to a compound osmotic pump controlled-release preparation containing acipimox and simvastatin and its preparation method. Background technique [0002] With the continuous development of medical science, people realize that the high content of cholesterol and fat is the basic cause of cardiovascular disease, and hyperlipidemia is the main risk factor of coronary heart disease and hypertension. Therefore, people began to focus on the development of blood lipid regulating drugs as the prevention and treatment of cardiovascular diseases. Since the late 1980s, a large number of blood lipid-lowering drugs have been launched, among which statins have been well received by people, and their clinical efficacy is unmatched by other types of blood lipid regulating drugs. Ove...
