- Known hypersensitivity or any contraindication to atorvastatin (LIPITOR®).
- Pregnant or lactating women.

- Unstable angina pectoris.
- Disorders of the hematologic, digestive or central nervous systems including cerebrovascular disease and degenerative disease that would limit study evaluation or participation.
- Uncontrolled or newly diagnosed (within 1 month of study entry) diabetes mellitus.
- Uncontrolled endocrine or metabolic disease known to influence serum lipids or lipoproteins.
- Known impairment of renal function (plasma creatinine \>2.0 mg/dL), dysproteinemia, nephrotic syndrome or other renal disease.
- Active or chronic hepatobiliary or hepatic disease.
- Participants who are known to be Human Immunodeficiency Virus (HIV) positive.

- Lipid-altering agents, other than study drugs for the whole duration of the study.

- Cardiovascular drugs such as: beta blockers, calcium channel blockers, ACE inhibitors, nitrates or α-adrenergic blockers or thiazide diuretics will be allowed, provided the dose remains constant for the duration of the study and the participant has received a stable dose for at least 8 weeks before the initial qualifying LDL-C level is drawn. Aspirin up to 325 mg/day is permitted. In addition, aspirin is allowed as a as needed (prn) concomitant medication.
- Treatment with psyllium or other fiber-based laxatives unless treated with a stable regimen for at least 4 weeks before initial qualifying lipid determination. Dose must remain constant throughout the study period.
- Treatment with troglitazone (Rezulin®) unless treated with a stable regimen for at least 6 weeks before initial qualifying lipid determination. Dose must remain constant throughout the study period.
- Treatment with cyclosporine.
- Use of any investigational drugs within 30 days of study entry.
- Treatment with agents with known drug interaction with atorvastatin including antifungal azoles (itraconazole and ketoconazole), macrolide antibiotics (erythromycin and clarithromycin), and nefazodone.
