Before we begin: If lifestyle changes do not help to control or lower high blood pressure (hypertension), your health care provider may prescribe blood pressure medicines.
This tutorial walks you through everything you need to know about blood pressure medicines. We explain it in plain language, step by step, so whether you are a student, a patient, or simply curious, you will come away with a solid understanding.
We cover what it is, why it matters, how it is diagnosed, and what you can do about it. Key facts are called out along the way.
What is high blood pressure? High blood pressure, also called hypertension, is when blood puts too much pressure against the walls of your arteries. Almost half of American adults have high blood pressure, usually with no symptoms. But it can cause serious problems such as stroke, heart failure, heart attack, and kidney disease.
What lifestyle changes can help lower high blood pressure? Healthy lifestyle changes can help reduce high blood pressure:
Losing weight
Being physically active
Managing stress
Reducing sodium in your diet
Avoiding alcohol, tobacco, and illegal drugs
Getting enough sleep
What if lifestyle changes alone cannot lower blood pressure? Sometimes lifestyle changes alone cannot control or lower your high blood pressure. In that case, your health care provider may prescribe blood pressure medicines.
How do blood pressure medicines work? The most commonly used blood pressure medicines work in different ways to lower blood pressure:
Angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs) keep your blood vessels from narrowing as much and allows blood to move through them with less pressure.
Beta blockers help your heart beat slower and with less force. This means that your heart pumps less blood through your blood vessels. Beta blockers are typically used only as a backup option or if you also have certain other conditions.
Calcium channel blockers prevent calcium from entering the muscle cells of your heart and blood vessels. This allows the blood vessels to relax.
Diuretics remove extra water and sodium (salt) from your body. This lowers the amount of fluid in your blood. Diuretics are often used with other high blood pressure medicines, sometimes in one combined pill.
Often, two or more medicines work better than one. If these medicines do not lower your blood pressure enough, your provider may suggest that you take another type of blood pressure medicine.
While taking the medicines, it is still important to keep up with your healthy lifestyle changes. Doing both helps keep blood pressure lower than lifestyle changes or medicines alone.
