How it works

Amlodipine belongs to a class of drugs called calcium channel blockers. A class of drugs is a group of medications that work in a similar way. These drugs are often used to treat similar conditions.

Amlodipine blocks calcium from entering certain tissues and arteries. This makes it easier for them to relax so that blood can flow more easily to your heart.

If you’re taking amlodipine for chest pain, this drug reduces your risk of hospitalization and surgeries due to chest pain.
