    Abstract:
    POLARIS investigated the efficacy and safety of rosuvastatin 40 mg and atorvastatin 80 mg in high-risk patients with hypercholesterolemia. Patients (n=871) were randomized to rosuvastatin 40 mg/day or atorvastatin 80 mg/day for 26 weeks. The primary endpoint was percentage change in LDL-C levels at 8 weeks. Secondary assessments included safety and tolerability, NCEP ATP III LDL-C goal achievement, change in other lipids and lipoproteins at 8 and 26 weeks, and health economics. Mean LDL-C levels were reduced significantly more with rosuvastatin 40 mg than with atorvastatin 80 mg at 8 weeks (-56% versus -52%, p<0.001). The proportion of patients achieving the NCEP ATP III LDL-C goal at 8 weeks was significantly higher in the rosuvastatin 40 mg group (80% versus 72%, p<0.01). Significant differences in the change from baseline in high-density lipoprotein cholesterol (HDL-C) (+9.6% versus +4.4%) and apolipoprotein (Apo)A-I levels (+4.2 versus -0.5) were observed between rosuvastatin and atorvastatin (all p<0.05). Both treatments were well tolerated. Based on a US analysis, rosuvastatin used fewer resources and delivered greater efficacy. Intensive lipid-lowering therapy with rosuvastatin 40 mg/day provided greater LDL-C-lowering efficacy than atorvastatin 80 mg/day, enabling more patients to achieve LDL-C goals. Rosuvastatin may therefore improve LDL-C goal achievement in high-risk patients with hypercholesterolemia.
