Efficacy and safety of rosuvastatin compared with pravastatin and simvastatin in patients with hypercholesterolemia: A randomized, double-blind, 52-week trial

Objective The primary objective of this trial was to compare the efficacy of rosuvastatin with that of pravastatin and simvastatin for lowering low-density lipoprotein cholesterol (LDL-C) levels. Methods In this randomized, double-blind, multicenter trial, lipid levels were measured in 477 patients (baseline LDL-C greater than or equal to 160 and <250 mg/dL) who received fixed doses of 5 mg of rosuvastatin, 10 mg of rosuvastatin, 20 mg of pravastatin, or 20 mg of simvastatin for 12 weeks. For an additional 40 weeks, individual daily doses were sequentially doubled to a maximum of 80 mg of rosuvastatin, 40 mg of pravastatin, and 80 mg of simvastatin, according to investigator discretion and if National Cholesterol Education Program Adult Treatment Panel II (ATP II) LDL-C goals were not achieved. Results At 12 weeks, percent LDL-C reductions after both 5-mg and 10-mg rosuvastatin treatment, which were 39.1% and 47.4%, respectively, were significantly different (P <.05) from LDL-C reductions after 20-mg pravastatin (26.5%) and 20-mg simvastatin (34.6%) treatment. After 52 weeks, more rosuvastatin-treated patients remained at their starting dose than did simvastatin or pravastatin patients. After dose titration, 88% and 87.5% of the rosuvastatin 5-mg and 10-mg groups, respectively, achieved their ATP 11 LDL-C goals, compared with 60% for pravastatin and 72.5% for simvastatin. All study treatments were well tolerated. Conclusion Rosuvastatin reduced LDL-C levels more than pravastatin or simvastatin in patients with hypercholesterolemia in a 52-week close-titration study.
