Usage / Indications

Ambrisentan (Plumonext) includes ambrisentan, an ETA receptor antagonist that is used to manage patients with pulmonary arterial hypertension (PAH, WHO Group 1) in adults. PAH is the term that is used to refer to abnormally high blood pressure levels in the arteries carrying blood from the right side of the heart into the lungs.

The drug inhibits endothelin type A (ETA) receptors, which play a major role in the narrowing of the arteries. By blocking the action of endothelin-1, the main natural compound causing constricted blood vessels, ambrisentan allows relaxation of the lungs' blood vessels and reduction of vascular resistance. As a result, therapy helps to improve exercise capacity and to prevent worsening of the symptoms. The drug can also be administered in combination with tadalafil to prevent progression of the disease, hospital admission for worsening of PAH and to improve exercise tolerance.

Ambrisentan has an important warning concerning its safety for embryos and fetuses and cannot be used in pregnant women.

Discuss with your healthcare provider if your condition does not improve or the improvement is slower than expected.
