Comparison of the efficacy and safety of rosuvastatin 10 mg and atorvastatin 20 mg in high-risk patients with hypercholesterolemia--Prospective study to evaluate the Use of Low doses of the Statins Atorvastatin and Rosuvastatin (PULSAR).

BACKGROUND: Many patients at high risk of cardiovascular disease do not achieve recommended low-density lipoprotein cholesterol (LDL-C) goals. This study compared the efficacy and safety of low doses of rosuvastatin (10 mg) and atorvastatin (20 mg) in high-risk patients with hypercholesterolemia. METHODS: A total of 996 patients with hypercholesterolemia (LDL-C > or = 3.4 and < 5.7 mmol/L [130 and 220 mg/dL]) and coronary heart disease (CHD), atherosclerosis, or a CHD-risk equivalent were randomized to once-daily rosuvastatin 10 mg or atorvastatin 20 mg. The primary endpoint was the percentage change from baseline in LDL-C levels at 6 weeks. Secondary endpoints included LDL-C goal achievement (National Cholesterol Education Program Adult Treatment Panel III [NCEP ATP III] goal < 100 mg/dL; 2003 European goal < 2.5 mmol/L for patients with atherosclerotic disease, type 2 diabetes, or at high risk of cardiovascular events, as assessed by a Systematic COronary Risk Evaluation (SCORE) risk > or = 5% or 3.0 mmol/L for all other patients), changes in other lipids and lipoproteins, cost-effectiveness, and safety. RESULTS: Rosuvastatin 10 mg reduced LDL-C levels significantly more than atorvastatin 20 mg at week 6 (44.6% vs. 42.7%, p < 0.05). Significantly more patients achieved NCEP ATP III and 2003 European LDL-C goals with rosuvastatin 10 mg compared with atorvastatin 20 mg (68.8% vs. 62.5%, p < 0.05; 68.0% vs. 63.3%, p < 0.05, respectively). High-density lipoprotein cholesterol was increased significantly with rosuvastatin 10 mg versus atorvastatin 20 mg (6.4% vs. 3.1%, p < 0.001). Lipid ratios and levels of apolipoprotein A-I also improved more with rosuvastatin 10 mg than with atorvastatin 20 mg. The use of rosuvastatin 10 mg was also cost-effective compared with atorvastatin 20 mg in both a US and a UK setting. Both treatments were well tolerated, with a similar incidence of adverse events (rosuvastatin 10 mg, 27.5%; atorvastatin 20 mg, 26.1%). No cases of rhabdomyolysis, liver, or renal insufficiency were recorded. CONCLUSION: In high-risk patients with hypercholesterolemia, rosuvastatin 10 mg was more efficacious than atorvastatin 20 mg at reducing LDL-C, enabling LDL-C goal achievement and improving other lipid parameters. Both treatments were well tolerated.

Comparison of the efficacy of rosuvastatin versus atorvastatin, simvastatin, and pravastatin in achieving lipid goals: results from the STELLAR trial.

In the Statin Therapies for Elevated Lipid Levels compared Across doses to Rosuvastatin (STELLAR) trial, the efficacy of rosuvastatin calcium (Crestor) was compared with that of atorvastatin (Lipitor), simvastatin (Zocor), and pravastatin (Pravachol) for lowering plasma low-density lipoprotein cholesterol (LDL-C) after 6 weeks of treatment. In this multicenter, parallel-group, open-label trial, adults with hypercholesterolemia were randomized to treatments with rosuvastatin 10, 20, 40, or 80 mg, atorvastatin 10, 20, 40, or 80 mg, simvastatin 10, 20, 40, or 80 mg, or pravastatin 10, 20, or 40 mg. Efficacy and safety results from this trial have been previously published. The additional analyses included in this report show that 53% (83/156) to 80% (125/157) of patients in the rosuvastatin 10- to 40-mg groups achieved LDL-C levels < 100 mg/dl (< 2.6 mmol/l), compared with 18% (28/158) to 70% (115/165) of patients who received atorvastatin, 8% (13/165) to 53% (86/163) of patients who received simvastatin, and 1% (1/160) to 8% (13/161) of patients who received pravastatin. Other additional analyses showed that more patients in the rosuvastatin 10- to 40-mg groups than in the comparator groups who were at high risk of coronary heart disease according to National Cholesterol Education Program Adult Treatment Panel (ATP) III, Joint European Societies, or Canadian guidelines achieved the LDL-C goals of < 100 mg/dl (< 2.6 mmol/l) (55% to 77% compared with 0 to 64%), < 3.0 mmol/l (< 116 mg/dl) (76% to 94% compared with 6% to 81%), and < 2.5 mmol/l (< 97 mg/dl) (47% to 69% compared with 0 to 53%), respectively. Results favoring rosuvastatin versus the comparators were also reported for patients: (a) who had triglycerides > or = 200mg/dl (> or = 2.3 mmol/l), and achieved both ATP III LDL-C and non-high-density lipoprotein cholesterol (non-HDL-C) goals (80% to 84% versus 15% to 84%); (b) overall who achieved the Canadian LDL-C goals of < 2.5 (< 97 mg/dl) to < 5.0 mmol/l (< 193 mg/dl) (85% to 91% versus 44% to 86%); and (c) who achieved all 3 Canadian goals for LDL-C, triglycerides (< 3.0 mmol/l [< 266 mg/dl] to < 2.0 mmol/l [< 177 mg/dl]), and the total cholesterol/high-density lipoproteincholesterol ratio (< 4 to < 7) (70% to 83% versus 35% to 79%).
