What is blood pressure lowering medicine used for?
There are several different types of medicine that can treat high blood pressure. High blood pressure makes the heart work harder and can weaken the blood vessels. If it is not treated, high blood pressure increases the risk of heart attack, heart failure, stroke, and kidney failure.
Sometimes lifestyle changes are all you need to lower your blood pressure. The changes may include weight loss, having less salt in your diet, and more physical activity. If these changes don’t lower your blood pressure enough, your healthcare provider may prescribe one or more types of blood pressure medicine.
How does it work?
The different types of blood pressure medicine lower blood pressure in different ways.
- Diuretics help your body get rid of extra salt (sodium) and water. They are also called water pills.
- Beta blockers slow the heart rate. Some beta blockers also relax and open up blood vessels, which helps blood flow more easily.
- Vasodilators, ACE inhibitors, ARBs, and calcium channel blockers relax and open up narrowed blood vessels.
