Abstract

The present invention offers an anti-hyperlipemia composition, containing Acipimox and Pitavastatin, or their salts, esters and solvates, the proportion by weight is (50-800): 1, preferably (100-400): 1, more preferably 200:1. The effect of anti-hyperlipemia is better than the single drug prescription with same dose, which represents the two medicaments have cooperation effect, also have not apparent toxicity effect.

Description

Technical field [0001] The invention relates to a new composition for treating hyperlipidemia, especially a composition containing acipimox, pitavastatin calcium and pharmaceutical auxiliary materials. 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 prevention and treatment trials has ...
