High doses of rosuvastatin are superior to low doses of rosuvastatin plus fenofibrate or n-3 fatty acids in mixed dyslipidemia

Abstract

The aim of the study was to compare the efficacy of high-dose rosuvastatin, low-dose rosuvastatin plus fenofibrate and low-dose rosuvastatin plus omega-3 fatty acids with regard to the lipid profile in patients with mixed hyperlipidemia. The primary endpoint was changes in non-high density lipoprotein-cholesterol (non-HDL-C) levels. Study participants were randomly allocated to receive rosuvastatin 40 mg (n = 30, R group), rosuvastatin 10 mg plus fenofibrate 200 mg (n = 30, RF group) or rosuvastatin 10 mg plus n-3 fatty acids 2 g (n = 30, RN group). Non-HDL-C levels were reduced in all groups: in R group by 54%, in RF group by 42% and in RN group by 42%. Significant reductions in total cholesterol (TC), low density lipoprotein (LDL)-C and triglyceride levels were observed in all groups. The reductions in total and LDL-C were greatest in the R group while a more pronounced reduction of triglycerides in the RF group compared with that in the R and the RN group was observed. HDL-C levels were significantly increased only in the RF group. In conclusion, high doses of rosuvastatin and small doses of rosuvastatin plus either fenofibrate or n-3 fatty acids exhibit favorable effects on both LDL-C and non-HDL-C levels. However, rosuvastatin monotherapy more potently reduces these parameters. The combination of rosuvastatin plus fenofibrate leads to a greater decrease in triglyceride levels and a greater increase in HDL-C levels compared with the other two treatments. While awaiting the results of ongoing trials high doses of rosuvastatin may represent the treatment of choice in individuals with mixed dyslipidemia.
