Rosuvastatin demonstrates greater reduction of low-density lipoprotein cholesterol compared with pravastatin and simvastatin in hypercholesterolaemic patients: a randomized, double-blind study

Abstract

Background: Rosuvastatin (Crestor), a new, highly efficacious statin, has demonstrated dose-dependent low-density lipoprotein cholesterol (LDL-C) reductions of up to 65% in a dose-ranging programme with doses of 1 to 80 mg.

Design: A randomized, double-blind multicentre trial compared rosuvastatin with commonly used starting doses of pravastatin and simvastatin to determine relative efficacy in LDL-C reduction and impact on other lipid parameters in primary hypercholesterolaemia.

Methods and results: A total of 502 patients (greater-than-or-equal 18 years; LDL-C greater-than-or-equal 4.14 mmol/l [160 mg/dl] and < 6.50 mmol/l [250 mg/dl] and triglycerides less-than-or-equal 4.52 mmol/l [400 mg/dl]) were randomized to 12 weeks of rosuvastatin 5 mg (n = 120) or 10 mg (n = 115), pravastatin 20 mg (n=]137) or simvastatin 20 mg (n = 130). Rosuvastatin 5 and 10 mg reduced LDL-C by 42 and 49%, respectively, compared with 28% for pravastatin (P < 0.001 versus both rosuvastatin doses) and 37% for simvastatin (P < 0.01 versus rosuvastatin 5 mg; P < 0.001 versus 10[?]mg). National Cholesterol Education Program Adult Treatment Panel II (NCEP ATP II) goals were achieved by 87% of rosuvastatin 10[?]mg patients, 71% of rosuvastatin 5[?]mg patients, 53% of pravastatin patients, and 64% of simvastatin patients; similar proportions of patients achieved NCEP ATP III goals. European Atherosclerosis Society (EAS) goals were achieved by 83, 63, 20 and 50% of patients, respectively. All study treatments were well tolerated.

Conclusions: Both doses of rosuvastatin were more effective than pravastatin and simvastatin in meeting NCEP ATP II and EAS LDL-C targets. Rosuvastatin 10 mg was more effective than pravastatin and simvastatin in meeting NCEP ATP III targets.
