Caduet (Amlodipine and Atorvastatin) - Oral

What Is Caduet?

Caduet is an oral pill that combines two prescription medications: Norvasc (amlodipine) and Lipitor (atorvastatin). It is used in people for whom treatment with both amlodipine and atorvastatin is needed.

Amlodipine belongs to a group of drugs called calcium channel blockers and works by relaxing blood vessels. Amlodipine can be used to lower blood pressure or treat chest pain (angina). Atorvastatin is a statin medicine, also called an HMG-CoA reductase inhibitor, that decreases cholesterol by limiting how much cholesterol your liver makes.

Caduet is available as a tablet to be taken by mouth.

What Is Caduet Used For?

Your healthcare provider may prescribe Caduet if you need treatment with both amlodipine and atorvastatin.

Amlodipine is used to treat:

Atorvastatin helps:

  • Lower cholesterol or triglycerides (fat) levels in the blood 
  • Decrease the risk of heart attack, stroke, or other heart problems in people with heart disease or risk factors for heart disease

In clinical trials, once-daily treatment with amlodipine and atorvastatin effectively reduced systolic blood pressure and low-density lipoprotein cholesterol (LDL-C, also known as "bad" cholesterol). When used along with diet and exercise, medications that lower blood pressure and cholesterol can help decrease your chances of developing a heart attack and stroke.
