Can bosentan reverse lung artery thickening? small study investigates

This study looked at whether bosentan (Tracleer) can reduce the thickness of lung artery walls in people with a type of high blood pressure in the lungs (pulmonary arterial hypertension, or PAH). Eleven adults with PAH took bosentan for 6 months. Researchers measured artery wall thickness and how well small blood vessels in the lungs responded to natural chemicals. The goal was to see if the drug could improve artery structure and function.
