Brief Summary

Participants currently taking atorvastatin 20 mg will be switched to either atorvastatin 40 mg or ezetimibe/simvastatin 10 mg/40 mg (10/40). After 6 weeks of treatment, the percent reduction in low-density lipoprotein cholesterol (LDL-C) will be assessed and compared between the two treatment groups.
