Why is it prescribed?
Ambrisentan is used in adults to treat high blood pressure in the pulmonary arteries (pulmonary arterial hypertension).
Side effects may include:
- nasal congestion (runny or blocked nose), red and sore throat, sinusitis
- constipation, abdominal pain, nausea, vomiting flushing (redness of the skin),
- fluid retention (edema)
- feeling tired or weak
- palpitations (fast or irregular heartbeat)
- vision changes, (blurry or other changes to vision) ringing in the ears (tinnitus)
- symptoms related to low blood pressure, like dizziness or fainting.
Ambrisentan is a specific, competitive endothelin receptor antagonist, with ETA receptor selectivity. It reduces high blood pressure by relaxing the pulmonary arteries. This makes it easier for the heart to pump blood to the lungs.
Ambrisentan should not be used in anyone less than 18 years of age. At this time, safety and effectiveness have not been established in this age group.
Do not take ambrisentan if you:
- are allergic to ambrisentan or any ingredients in the tablet
- have liver disease or abnormal liver test results.
- have a lung condition called idiopathic pulmonary fibrosis (IPF)
Talk to your doctor or pharmacist if you:
- have or ever had liver problems
- have a low number of red blood cells (anemia)
- have swelling (edema)
