Patient leaflet - Ambrisentan Axunio 10 mg film-coated tablets

1. What Ambrisentan is and what it is used for

Ambrisentan contains the active substance ambrisentan. It belongs to a group of medicines called other antihypertensives (used to treat high blood pressure).

It is used to treat pulmonary arterial hypertension (PAH) in adults. PAH is high blood pressure in the blood vessels (the pulmonary arteries) that carry blood from the heart to the lungs. In people with PAH, these

arteries get narrower, so the heart has to work harder to pump blood through them. This causes people to feel tired, dizzy and short of breath.

Ambrisentan widens the pulmonary arteries, making it easier for the heart to pump blood through them. This lowers the blood pressure and relieves the symptoms. Ambrisentan may also be used in combination with other medicines used to treat PAH.

2. What you need to know before you take Ambrisentan

Do not take Ambrisentan:

  • if you are allergic to ambrisentan, soya, or any of the other ingredients of this medicine (listed in section 6)
  • if you are pregnant, if you are planning to become pregnant, or if you could become pregnant because you are not using reliable birth control (contraception). Please read the information under ‘Pregnancy’
  • if you are breast-feeding. Read the information under ‘Breast-feeding’
