New hope for stubborn high blood pressure: drug targets blood vessels

This study is for people with resistant hypertension, meaning their blood pressure stays high even with three or more medications. Researchers want to see if a drug that blocks endothelin-1, a substance that tightens blood vessels, can improve blood vessel function and lower blood pressure over 8 weeks. About 24 adults aged 30-80 will take part. The goal is to find a better way to control this serious condition and reduce heart risks.
