Can a heart drug spray help lung blood vessels?
NCT ID NCT07214129
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether breathing in nitroglycerin (a medicine that opens blood vessels) is safe and effective for people with pulmonary arterial hypertension (PAH), a condition where lung blood vessels narrow. Twenty adults with PAH took part. The goal was to see if the spray could widen lung arteries and improve blood flow. This was a small, early-stage study focused on safety and how the body responds.
