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.

DRUGsimvastatin 40 mg or atorvastatin 20 mg

simvastatin 40 mg or atorvastatin 20 mg tablets, taken once daily for six weeks.

DRUGRosuvastatin

rosuvastatin 10 mg tablets, taken once daily for six weeks.

DRUGatorvastatin 10 mg or simvastatin 20 mg

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.

Inclusion criteria

* Patient has not taken common statins or ezetimibe within 6 weeks of study screening or patient is currently taking a daily dose of the following statins for 6 weeks prior to study screening: simvastatin, atorvastatin, pravastatin, fluvastatin, ezetimibe, lovastatin, or ezetimibe + fluvastatin * Patient is willing to go on a cholesterol and glucose lowering diet for the duration of the study * Patient is willing to remain abstinent or use birth control for the duration of the study * Patient has Diabetes Mellitus with cardiovascular disease
