Amlodipine & Atorvastatin

Amlodipine/atorvastatin is a prescription medicine used to treat people with high blood pressure and high cholesterol. It is a single tablet containing two medications, amlodipine and atorvastatin.

Amlodipine belongs to a group of medications called calcium channel blockers. It works by relaxing blood vessels so the heart does not need to pump as hard. Atorvastatin belongs to a group of medications called statins (or HMG-CoA reductase inhibitors). It works by blocking an enzyme that affects the rate of production of cholesterol in the body.

Amlodipine/atorvastatin comes in a tablet form and is taken by mouth, once a day, with or without food.

Amlodipine/atorvastatin is a prescription medication used to treat people who have both high blood pressure and high cholesterol.
