Amlodipine maleate is primarily used in the treatment of hypertension and angina. It works by relaxing blood vessels, which helps to lower blood pressure and improve blood flow to the heart. This makes it effective in managing high blood pressure, reducing the risk of strokes, heart attacks, and kidney problems. Additionally, it is used to treat chronic stable angina and vasospastic angina, providing relief from chest pain by enhancing oxygen supply to the heart. Its long-acting nature allows for once-daily dosing, improving patient compliance. It is often prescribed as part of a comprehensive treatment plan that includes lifestyle changes and other medications.
