Patient Education

Macitentan


Macitentan is used to manage the symptoms of pulmonary arterial hypertension (PAH; high blood pressure in the vessels that carry blood to the lungs). Macitentan is in a class of medications called endothelin receptor antagonists. It works by stopping the action of endothelin, a natural substance that causes blood vessels to narrow and prevents normal blood flow in people who have PAH.
