What is Amlodipine (Norvasc)?

Amlodipine, commonly known as Norvac, belongs to a class of medications called calcium channel blockers. It works by relaxing blood vessels, allowing blood to flow more smoothly, and thereby lowering blood pressure. This medication is primarily prescribed to treat high blood pressure (hypertension) and certain types of chest pain (angina).

How Amlodipine (Norvasc) Works

Amlodipine functions by inhibiting the influx of calcium ions into both smooth muscle cells and cardiac muscle cells during depolarization. This action prevents the contraction of these muscles, leading to vasodilation (widening of blood vessels) and reduced workload on the heart.
