Antihypertensive medications are drugs used to lower high blood pressure, also known as hypertension. High blood pressure can lead to serious health issues, including heart disease and stroke. These medications work by relaxing blood vessels, reducing blood volume, or blocking certain hormones that can raise blood pressure. There are several classes of antihypertensive drugs, including diuretics, ACE inhibitors, beta-blockers, and calcium channel blockers. Each class works differently to help manage blood pressure levels. Doctors often prescribe these medications based on individual patient needs and health conditions to ensure effective treatment.
