The name of the product is Ambrisentan film-coated tablets (called Ambrisentan throughout this leaflet). These tablets contain 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, adolescents and children aged 8 years and over. 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.
Talk to your doctor or pharmacist before taking Ambrisentan if you have:

Your doctor may need to adjust your dose of Ambrisentan if you start taking cyclosporine A (a medicine used after transplant or to treat psoriasis).
If you are taking rifampicin (an antibiotic used to treat serious infections), your doctor will monitor you when you first start taking Ambrisentan.
If you are taking other medicines to treat PAH (e.g. iloprost, epoprostenol, sildenafil) your doctor may need to monitor you.
Ambrisentan may harm unborn babies conceived before, during or soon after treatment.
If you are a woman who could become pregnant, your doctor will ask you to take a pregnancy test before you start taking Ambrisentan and regularly while you are taking this medicine.
