Ambrisentan
An endothelin receptor antagonist that blocks endothelin-1, a potent constrictor of blood vessels in the lungs, used to treat pulmonary arterial hypertension (PAH) by relaxing and widening the pulmonary arteries. It improves exercise capacity and slows disease progression in patients with PAH, reducing the strain on the right side of the heart.
