Ambristar 5 Tablet is used to manage pulmonary arterial hypertension (PAH) in adults, a serious condition in which high blood pressure develops in the arteries supplying the lungs. It is a single-ingredient medicine containing ambrisentan, and belongs to a class of medicines called endothelin receptor antagonists.
This medicine works by blocking endothelin, a natural substance that narrows blood vessels, which relaxes the blood vessels in the lungs, improves breathing, increases exercise capacity and helps slow the progression of PAH. Take it as prescribed, swallow it whole, with or without food. Regular blood tests are needed during treatment.
Keeping to your monitoring appointments, avoiding over-exertion and following your doctor's lifestyle advice support your treatment alongside this medicine.
Before taking this medicine, tell your doctor if you may be pregnant or are planning pregnancy, as it must not be used in pregnancy, and tell them about any liver problems and other medicines you take. Regular blood tests check your liver. Report worsening breathlessness, swelling, or any possibility of pregnancy.
