Effectiveness

How Bosentan Affects PatientsBosentan is a drug that helps treat pulmonary arterial hypertension (PAH) by blocking endothelin, a chemical that causes blood vessels to narrow. Blocking endothelin helps prevent the harmful effects of PAH.

How Bosentan works in the bodyEndothelin-1 (ET-1) is a hormone that affects the body by binding to receptors in the blood vessels and muscles. It seems to have a stronger effect on ET-A receptors than on ET-B receptors. People with pulmonary arterial hypertension have more ET-1 in their lungs and bloodstream. Bosentan works by blocking the effects of ET-1 at the ET-A and ET-B receptors.
