Efficacy and safety of rosuvastatin versus atorvastatin in high-risk Chinese patients with hypercholesterolemia: a...

To evaluate and compare the efficacy and safety of rosuvastatin versus atorvastatin in a high-risk Chinese population with hypercholesterolemia.

This 6 week, prospective, multicenter, double-blind, three-arm, parallel-group, active-controlled study randomized adult Chinese patients (low-density lipoprotein cholesterol [LDL-C] ≥ 130-<250 mg/dL statin-naive and ≥100-<160 mg/dL in statin treated) to receive rosuvastatin (5 mg or 10 mg) or atorvastatin 10 mg. Patients not achieving National Cholesterol Education Program (NCEP) Adult Treatment Panel (ATP) III LDL-C targets in the randomized phase were administered rosuvastatin 10 mg and 20 mg in the open-label phase.

In total 414 patients (mean age: 59.5 ± 9.51 years, 59.4% females, mean LDL-C: 4.242 ± 0.676 mmol/L (rosuvastatin 5 mg), 4.13 ± 0.682 mmol/L (rosuvastatin 10 mg) and 4.213 ± 0.662 mmol/L (atorvastatin 10 mg) were analyzed. Compared with atorvastatin 10 mg, rosuvastatin 5 mg (-41.70% vs. -38.67%, p = .132) and rosuvastatin 10 mg showed greater LDL-C reduction (-46.28% vs. -38.67%, p = .0002). LDL-C target achievement rates with rosuvastatin 5 mg, rosuvastatin 10 mg and atorvastatin 10 mg were 61.0%, 79.1% and 58.3% in the randomized phase. In the open-label phase, LDL-C target achievement occurred in >40% with both doses of rosuvastatin. The rate of ≥1 adverse event was similar with rosuvastatin 5 mg (12.4%), 10 mg (11.7%) and atorvastatin 10 mg (8.9%).

Rosuvastatin 5 mg demonstrated non-inferiority and rosuvastatin 10 mg demonstrated superiority to atorvastatin 10 mg for lowering LDL-C in high-risk Chinese patients with dyslipidemia, which was maintained through the open-label phase.
