Rosuvastatin Alone or With Extended‐Release Niacin: A New Therapeutic Option for Patients With Combined Hyperlipidemia

Abstract

Combination therapy with a statin and niacin may provide optimal therapy for patients with combined hyperlipidemia and low levels of high-density lipoprotein (HDL) cholesterol. The authors assessed the efficacy and safety of rosuvastatin monotherapy, extended-release (ER) niacin monotherapy, or rosuvastatin and ER niacin combined therapy in patients with atherogenic dyslipidemia. In a 24-week, open-label, multicenter trial, men and women aged > or =18 years with fasting levels of total cholesterol > or =200 mg/dL, HDL cholesterol > or =45 mg/dL, triglycerides 200-800 mg/dL, and apolipoprotein B > or =110 mg/dL were randomly assigned to one of four treatment groups: rosuvastatin 10-40 mg, ER niacin 0.5-2 g, rosuvastatin 40 mg plus ER niacin 0.5-1 g, or rosuvastatin 10 mg plus ER niacin 0.5-2 g. Daily doses of rosuvastatin 40 mg monotherapy reduced low-density lipoprotein (LDL) cholesterol and non-HDL cholesterol levels significantly more than did either ER niacin 2 g monotherapy or rosuvastatin 10 mg combined with ER niacin 2 g. Addition of ER niacin 1 g to rosuvastatin 40 mg did not further reduce total or non-HDL cholesterol. Triglyceride reductions were similar among the four treatment groups. ER niacin mono- and combined therapy produced significantly greater rises in HDL cholesterol and apolipoprotein A-1 than did rosuvastatin monotherapy. Rosuvastatin monotherapy was better tolerated than ER niacin taken either alone or with rosuvastatin. In this study, rosuvastatin very effectively improved the three major lipoprotein-lipid abnormalities of combined hyperlipidemia.
