Mechanism of action

Ambrisentan is an endothelin receptor antagonist (ERA) that preferentially binds to endothelin type-A (ETA) receptors. By blocking ETA receptors, it prevents endothelin-1-mediated vasoconstriction and smooth muscle proliferation in pulmonary blood vessels, thereby reducing pulmonary vascular resistance and improving hemodynamics in pulmonary arterial hypertension.
