Uses

Bosentan is used to treat high blood pressure in the lungs (pulmonary arterial hypertension). This condition is thought to be caused by increased levels of a certain natural substance (endothelin-1). This medication blocks the effects of endothelin-1, which helps lower blood pressure in the lungs, slow the worsening of symptoms from the disease, and improve your ability to exercise.
