Bosentan

Uses

Bosentan is used in the treatment of pulmonary arterial hypertension (PAH).

How it Works

How Bosentan works Bosentan is an endothelin receptor blocker that inhibits the action of endothelin, a natural substance that causes blood vessels to constrict. This constriction increases the pressure in the blood vessels of the lungs. Bosentan helps relax these blood vessels and enhances the blood supply to the lungs.

Side Effects

Common side effects of Bosentan include respiratory tract infection, headache, flushing (a sense of warmth in the face, ears, neck, and trunk), and fluid retention.
