Answer

Endothelin Receptor Antagonists

These agents are used for pulmonary hypertension associated with sickle cell disease.

Bosentan (Tracleer)

Bosentan improves pulmonary arterial hemodynamics by competitively binding to ET-1 receptors endothelin-A and endothelin-B in pulmonary vascular endothelium and pulmonary vascular smooth muscle. This leads to a significant increase in cardiac index associated with a significant reduction in pulmonary artery pressure, pulmonary vascular resistance, and mean right atrial pressure.
