Patient Medication Information: uses, side effects, how to take - Mar-Amlodipine
What is MAR-AMLODIPINE used for?
MAR-AMLODIPINE is used in adults and children 6 years of age and older to:
- Treat high blood pressure (hypertension), or

How does MAR-AMLODIPINE work?
MAR-AMLODIPINE belongs to a group of drugs called “calcium channel blockers”.
MAR-AMLODIPINE relaxes your blood vessels, which lets your blood flow more easily. This helps to lower your blood pressure.
MAR-AMLODIPINE controls chest pain by improving the supply of blood and oxygen to the heart. This reduces the amount of work that your heart has to do.
