New Treatments & Clinical Trials for Hypertension

Hypertension affects about one in three adults in the United States and is treated with a wide range of medications, from ACE inhibitors and ARBs to calcium channel blockers and diuretics. Most people need two or more drugs to reach target blood pressure, and treatment aims to prevent heart attack, stroke, and kidney damage over decades.

What's actually going on in research

Trials are testing new drug combinations that work through different pathways, devices that modulate kidney nerves or stimulate the carotid body, and approaches to resistant hypertension that doesn't respond to standard drugs. Researchers are also studying how to lower blood pressure earlier in people at risk and whether tighter targets prevent more events in certain groups.

What to know before you search

Eligibility typically depends on your blood pressure level, number of current medications, cardiovascular history, and kidney function.

What types of trials are currently open

• Drug trials — Testing new blood pressure medications or combinations, often comparing them to standard treatments to see if they lower blood pressure more or with fewer side effects.
• Device trials — Testing procedures like renal denervation or carotid body modulation that aim to lower blood pressure without daily pills.
• Resistant hypertension trials — Focused on people whose blood pressure stays high despite three or more medications, testing intensive drug regimens or devices.
• Target trials — Comparing different blood pressure goals, such as under 130 versus under 140, to see which prevents more heart attacks and strokes.
• Prevention trials — Testing whether treating people with high-normal blood pressure or early hypertension can prevent cardiovascular events years later.
