Problems solved by technology

Chinese patent application CN1425374A discloses the composition of acipimox and lovastatin, the disclosed ratio is that the weight ratio of acipimox and lovastatin is 25-50:1, and the preferred ratio is 25:1 or 37.5:1 , but the half-life of acipimox is short, only 2h, and its minimum effective plasma concentration is 0.2ug / ml
Ordinary immediate-release preparations and matrix-type sustained-release preparations are difficult to maintain effective blood drug concentrations during the dosing interval, and it is difficult to make compound drugs produce better synergy

Abstract

The invention relates to an osmotic pump preparation containing acipimox, lovastatin and other pharmaceutical excipients, wherein, the acipimox is the controlled-release part, the lovastatin is the rapid-release part; or the acipimox and the lovastatin are both the controlled-release parts. In addition, the invention further discloses a preparation method of an osmotic pump tablet of the composition, and the osmotic pump table which is prepared by applying the method can better bring the synergy of the acipimox and the lovastatin into play.

Description

technical field [0001] The invention belongs to the field of medicine, and in particular relates to an osmotic pump controlled-release formulation composition for treating hyperlipidemia containing two active ingredients of medicines. 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. Over the past ten years, the completion of several international large-scale coronary heart disease pre...
