Why is it prescribed?
Ambrisentan is used in adults to treat high blood pressure in the pulmonary arteries (pulmonary arterial hypertension). It can be used as an initiation therapy in combination with tadalafil.
Ambrisentan can be taken with or without food.
If you forget to take a dose, take as soon as you remember, then continue with the next dose at your usual time. Don’t take two tablets at the same time to make up for a forgotten dose.
Ambrisentan may increase liver enzymes or cause anemia (reduction in red blood cells). Your doctor will do regular blood tests to check for any changes in your liver function and for anemia.
