Used primarily as a calcium channel blocker to manage high blood pressure and angina. It works by relaxing blood vessels, improving blood flow, and reducing the heart's workload. Often administered intravenously in hospital settings for rapid control of hypertension, especially during surgeries or emergencies. Also prescribed in oral form for long-term management of chronic conditions. Helps prevent complications associated with high blood pressure, such as strokes or heart attacks. Requires careful monitoring to avoid side effects like dizziness or low blood pressure.
