Tezosentan is a non-selective ET_A and ET_B receptor antagonist.^[1] It acts as a vasodilator and was designed as a therapy for patients with acute heart failure. Recent studies have shown however, that tezosentan does not improve dyspnea or reduce the risk of fatal or nonfatal cardiovascular events.^[2]
