Overview of Endothelin Receptor Antagonists

"Time to clinical worsening was significantly faster with endothelin receptor antagonist."

Excess endothelin has been found in people with pulmonary hypertension, causing constriction in the blood vessels in the lungs. Endothelin receptor antagonists are designed to block the excess endothelin by various means.

SSc-PAH Outcomes Worse With Initial ERA. Time to clinical worsening was significantly faster with an endothelin receptor antagonist (ERA) as primary therapy for systemic sclerosis-related pulmonary arterial hypertension compared with a phosphodiesterase-5 (PDE5) inhibitor, or the combination of a PDE5 inhibitor and an ERA, researchers reported.
