Ambrisentan 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 drug is controlled through a special program. A program worker will call you each month to make sure that you have gotten a pregnancy test if you are a woman who may become pregnant. See also Warning and Precautions sections.
