Angiotensin II Receptor Blockers (ARBs) for High Blood Pressure
How It Works
These medicines block the action of a Reference hormone Opens New Window that causes blood vessels to narrow. As a result, blood vessels may relax and open up. This makes it easier for blood to flow through the vessels, which reduces blood pressure. Also, these drugs increase the release of sodium and water into the urine, which also lowers blood pressure.
