Brief summary
The purpose of this study is to determine the efficacy of switching to a combination tablet ezetimibe/simvastatin (10mg/20mg) versus rosuvastatin (10 mg) versus doubling the statin dose in those patients who have cardiovascular disease and diabetes mellitus not adequately controlled on simvastatin 20 mg or atorvastatin 10 mg.
Interventions
ezetimibe/simvastatin 10/20 mg tablets, taken once daily for six weeks.
simvastatin 40 mg or atorvastatin 20 mg tablets, taken once daily for six weeks.
rosuvastatin 10 mg tablets, taken once daily for six weeks.
All patients will take atorvastatin 10 mg tablets OR simvastatin 20 mg tablets, taken once daily in a 6-week screening/stabilization period prior to randomization.
