Amvasc (Amlodipine Besylate) is a calcium channel blocker used to treat high blood pressure (hypertension) and chest pain (angina). Amlodipine works by relaxing blood vessels, allowing the heart to pump blood more easily, reducing strain on the heart muscle. This medication helps lower blood pressure and improve blood flow, reducing the risk of heart attacks and strokes. Amlodipine is commonly prescribed to manage hypertension and certain types of angina. It is important to follow your healthcare provider's instructions when taking Amvasc to achieve optimal results.
