Bosentan (BOZENTAN) is a dual endothelin receptor antagonist important in the treatment of   pulmonary artery hypertension (PAH). It is licensed in the United States, the European Union and other countries by Actelion Pharmaceuticals for the management of PAH under the trade nameTracleer.

Bosentan is a competitive antagonist of endothelin-1 at the endothelin-A (ET-A) and endothelin-B (ET-B) receptors. Under normal conditions, endothelin-1 binding of ET-A or ET-B receptors causes pulmonary vasoconstriction. By blocking this interaction, bosentan decreases pulmonary vascular resistance. Bosentan has a slightly higher affinity for ET-A than ET-B.

Clinical uses 

Bosentan is indicated mainly for the treatment of pulmonary hypertension. In 2007, Tracleer (bosentan) was approved in the European Union also for reducing the number of new digital ulcers in patients with systemic sclerosis and ongoing digital ulcer disease.

In the United States, Tracleer® is indicated for the treatment of pulmonary arterial hypertension (WHO Group I) in patients with WHO Class II-IV symptoms, to improve exercise capacity and decrease the rate of clinical worsening.^[1]
