Brief summary: The purpose of this study is to determine whether ezetimibe/atorvastatin 10 mg/20 mg combination tablet is equivalent to the coadministration of ezetimibe 10 mg and atorvastatin 20 mg in lowering low-density-lipoprotein-cholesterol (LDL-C) after 6 weeks of treatment.


Eligibility criteria: Inclusion criteria:

* At low, moderate, or moderately high cardiovascular risk (according to National Cholesterol Education Program adult treatment panel III \[NCEP ATP III\] guidelines) and either statin-naïve with LDL-C ≥130 mg/dL for low risk or ≥100 mg/dL for moderate or moderately high risk OR on an allowable statin with on-therapy LDL-C ≥100 mg/dL in acceptable range and can safely discontinue and switch to study medication.
* Is willing to maintain a cholesterol-lowering diet throughout the study.
* Female of reproductive potential agrees to remain abstinent or to use (or have their partner use) 2 acceptable methods of birth control throughout the study.
* Female receiving non-cyclical hormone therapy, if maintained on a stable dose and regimen for at least 8 weeks prior to the study and if willing to continue the same regimen throughout the study.
* Off-therapy LDL-C levels are: for low risk patients, ≥130 mg/dL and ≤300 mg/dL; for moderate risk patients, ≥100 mg/dL and ≤300 mg/dL; for moderately high risk patients, ≥100 mg/dL and ≤275 mg/dL.
* Has liver transaminases ≤2 X upper limit of normal (ULN) with no active liver disease.
* Has creatine kinase (CK) levels ≤3 X ULN.
* Has triglyceride (TG) concentrations ≤400 mg/dL.

Exclusion criteria:

* Hypersensitivity or intolerance to ezetimibe, atorvastatin, the ezetimibe/atorvastatin combination tablet, or any component of these medications, or a history of myopathy or rhabdomyolysis with ezetimibe or any statin.
* Routinely consumes more than 2 alcoholic drinks per day (average \>14 alcoholic drinks per week).
* Is pregnant or lactating.
* Has been treated with any other investigational drug within 30 days of the study.
* Has any condition or situation that might pose a risk to the participant or interfere with participation in the study.
* Is high risk (according to NCEP ATP III guidelines), including but not limited to one or more of the following: diabetes mellitus (Type I or II), myocardial infarction, coronary artery bypass surgery, angioplasty, stable or unstable angina.
* Has any of the following medical conditions: congestive heart failure; uncontrolled cardiac arrhythmias or recent significant changes in electrocardiogram (ECG); homozygous familial hypercholesterolemia or has undergone LDL apheresis; partial ileal bypass, gastric bypass, or other significant intestinal malabsorption; uncontrolled hypertension; kidney disease; disease known to influence serum lipids or lipoproteins; hematologic, digestive, or central nervous systems disorder; known to be human immunodeficiency virus (HIV) positive; history of malignancy ≤5 years prior to the study, except for adequately treated basal cell or squamous cell skin cancer or in situ cervical cancer; mental instability; drug/alcohol abuse within the past 5 years, or major psychiatric illness not adequately controlled and stable on pharmacotherapy.
* Taking prohibited medications/foods including: systemic azole antifungals (e.g., fluconazole, ketoconazole), erythromycin or clarithromycin, and cyclosporine; ritonavir and saquinavir or lopinavir; \>5 cups of grapefruit juice per day; combination therapies of ezetimibe + simvastatin (10/80 mg), ezetimibe + atorvastatin (10/40 mg or 10/80 mg), ezetimibe + rosuvastatin (10/10 mg, 10/20 mg, or 10/40 mg), ezetimibe + pitavastatin (10/4 mg); non-statin lipid-lowering agents including fish oils containing \>900 mg/day of eicosapentaenoic acid and docosahexaenoic acid (EPA+DHA), red yeast extract, Cholestin™, bile acid sequestrants, other cholesterol-lowering agents, niacin (\>200 mg/day), or fibrates; systemic corticosteroids; psyllium, other fiber-based laxatives, phytosterol margarines, and/or over the counter (OTC) therapies known to affect serum lipid levels; orlistat or other anti-obesity medications and not maintained on a stable dose; any cyclical hormones; warfarin treatment without a stable dose or a stable International Normalized Ratio (INR).
