Neem Overview
Ambrisentan Overview
-
Ambrisentan is used alone or in combination with tadalafil (Adcirca, Cialis) to treat pulmonary arterial hypertension (PAH, high blood pressure in the vessels that carry blood to the lungs). Ambrisentan may improve the ability to exercise and slow the worsening of symptoms in people with PAH. Ambrisentan 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.
