A comparative study with rosuvastatin in subjects with metabolic syndrome: results of the COMETS study.

AIMS The efficacy and safety of rosuvastatin, atorvastatin, and placebo were compared in patients with the metabolic syndrome. METHODS AND RESULTS Patients with the metabolic syndrome with low-density lipoprotein cholesterol (LDL-C) > or =3.36 mmol/L (130 mg/dL) and multiple risk factors conferring a 10-year coronary heart disease risk score of >10% were randomized (2:2:1) to receive rosuvastatin 10 mg, atorvastatin 10 mg, or placebo for 6 weeks. Subsequently, the rosuvastatin 10 mg and placebo groups received rosuvastatin 20 mg and the atorvastatin 10 mg group received atorvastatin 20 mg for 6 weeks. LDL-C was reduced significantly more in patients receiving rosuvastatin 10 mg when compared with those receiving atorvastatin 10 mg at 6 weeks [intention-to-treat (ITT) population by randomized treatment: 41.7 vs. 35.7%, P < 0.001; ITT population by as-allocated treatment: 42.7 vs. 36.6%, P < 0.001]. Significant LDL-C reductions were also observed in patients receiving rosuvastatin when compared with those receiving atorvastatin at 12 weeks (48.9 vs. 42.5%, P < 0.001). More patients achieved LDL-C goals with rosuvastatin when compared with atorvastatin. Rosuvastatin increased high-density lipoprotein cholesterol significantly more than atorvastatin. Treatments were well tolerated. CONCLUSION At equivalent doses, rosuvastatin had a significantly greater effect than atorvastatin in lowering LDL-C and improving the lipid profile and was well tolerated in patients with the metabolic syndrome.
