Antihypertensives are medications used to lower high blood pressure, also known as hypertension. They help reduce the risk of serious health issues, such as heart attacks and strokes, by relaxing blood vessels, reducing heart rate, or decreasing blood volume. Common classes of antihypertensives include diuretics, ACE inhibitors, and beta-blockers. These medications are often prescribed based on individual health needs and may be used alone or in combination. Regular monitoring of blood pressure is essential to ensure the effectiveness of treatment and to adjust dosages as necessary. Lifestyle changes, such as diet and exercise, can also support antihypertensive therapy.
