The endothelin receptor antagonists were discovered in the late 1980s, with the first in class being bosentan (Tracleer), a mixed antagonist of endothelin receptors (ET A and ET B), which entered clinical development in 1993 and was approved as orphan drug for the treatment of pulmonary arterial hypertension in 2001 [23,195]. Generally, from its pharmacology, bosentan was believed to be a promising candidate for the management of clinical disorders associated with vasoconstriction.

Following oral administration, bosentan attains peak plasma Bosentan, a dual endothelin receptor antagonist, is indicated for the treatment of patients with pulmonary arterial hypertension (PAH). Following oral administration, bosentan attains peak plasma concentrations after approximately 3 hours. The absolute bioavailability is about 50%.
