Amlodipine

Key points

• Stops calcium ions from entering smooth muscle cells in the vessel wall, so blood vessels relax and widen.
• Also increases oxygen delivery to the heart muscle by widening the arteries, which can ease angina-related chest pain.
• Grapefruit juice can raise the amount absorbed into the bloodstream, potentially strengthening its blood-pressure-lowering effect.

What is Amlodipine?

Amlodipine is a pharmaceutical active that belongs to the calcium-channel blocker class. Several brands and forms exist because different manufacturers produce generic versions alongside the original, expanding access to this widely used heart medication.

What Amlodipine is used for

Doctors primarily use Amlodipine to treat Hypertension by relaxing blood vessels, which reduces the force against vessel walls. The medication also addresses Angina Pectoris by improving blood supply to the heart, easing the chest pain that occurs when the heart works harder.

How does Amlodipine work?

Amlodipine stops calcium from entering the muscle cells lining your blood vessels. This action allows those vessels to relax and widen, meaning your heart does not have to pump as hard to push blood through. The widened arteries also deliver more oxygen to the heart muscle, which reduces the frequency of angina attacks.

Amlodipine brands and forms

Brand options for Amlodipine include well-known names like Sevikar, Istin and Amlong. The available products come as a film-coated tablet or a standard tablet, which offer the same active compound with slightly different outer layers for swallowing ease. Combination products like Azor and Tribenzor mix Amlodipine with other blood pressure medications for broader control in the Heart & Blood Pressure category.
