The present invention provides a composition for treating hyperlipemia, which comprises the first active component acipimox, and the second active component atorvastatin, or the pharmaceutically acceptable salt, ester or solvate thereof. Weight ratio of the first to the second active component is (10-80):l. The composition is in the form of tablets, capsules, granules, pills or dropping pills. The combination of acipimox and atorvastatin is shown to have remarkably synergistic effect in decreasing serum total cholesterol, serum triglyceride and low density lipoprotein-cholesterol. Furthermore, in comparison with the combination of acipimox and pravastatin or the combination of acipimox and lorvastatin, the combination of acipimox and atorvastatin is shown to have more remarkable lipid decreasing effect, and have more advantageous effect of increasing high density lipoprotein-cholesterol.
