Direct Renin Inhibitors for High Blood Pressure
How It Works
Direct renin inhibitors block the enzyme renin from triggering a process that helps regulate blood pressure. As a result, blood vessels relax and widen, making it easier for blood to flow through the vessels, which lowers blood pressure.
Direct renin inhibitors, angiotensin-converting enzyme (ACE) inhibitors, and angiotensin II receptor blockers (ARBs) all target the same process that narrows blood vessels. But each type of medicine blocks a different part of the process.

Medicine is one of the many tools your doctor has to treat a health problem. Taking medicine as your doctor suggests will improve your health and may prevent future problems. If you don't take your medicines properly, you may be putting your health (and perhaps your life) at risk.
