Mechanism of action

Endothelin-1 is a potent vasoconstrictor that plays a key role in the pathophysiology of pulmonary hypertension. By selectively antagonizing endothelin receptors, SCH-58235 promotes vasodilation and reduces the proliferation of pulmonary vascular smooth muscle cells. This mechanism helps restore normal pulmonary hemodynamics and improve exercise capacity in patients with pulmonary hypertension.
