Background: This double-blind, multicenter, randomized trial compared rosuvastatin and atorvastatin for reducing low-density lipoprotein cholesterol (LDL-C) in adults with hypercholesterolemia and a high risk of coronary heart disease.
Methods: After a 6-week dietary lead-in period, patients with LDL-C levels > or =160 and <250 mg/dL and triglyceride levels < or =400 mg/dL were randomly assigned to 24 weeks' treatment in 1 of 3 groups, each with forced dose titrations at 12 and 18 weeks. Starting and titrated doses for each group were rosuvastatin 5, 20, and 80 mg (n = 127); rosuvastatin 10, 40, and 80 mg (n = 128); and atorvastatin 10, 40, and 80 mg (n = 128).
Results: At 24 weeks, LDL-C was reduced significantly more with 80 mg rosuvastatin (combined rosuvastatin group) than with atorvastatin 80 mg (60% vs 52% [P <.001]). At 12 weeks, rosuvastatin 5 and 10 mg reduced LDL-C significantly more than atorvastatin 10 mg (40% [P <.01], 47% [P <.001] vs 35%). At 18 weeks, LDL-C reductions were also significantly greater in both rosuvastatin groups than in the atorvastatin group (52% [P <.01], 59% [P <.001] vs 47%). Consequently, more patients receiving rosuvastatin achieved LDL-C goals. Total cholesterol, high-density lipoprotein cholesterol (HDL-C), non-HDL-C, apolipoproteins B and A-I, and all lipid ratios were more favorably modified by rosuvastatin at 24 weeks (P <.01). Effects of the 2 agents on triglycerides were similar.
Conclusions: Rosuvastatin was more efficacious than atorvastatin in modifying lipids in patients with hypercholesterolemia and a high coronary heart disease risk.
