Please note, this OEL/ADE monograph also applies to bosentan hydrate (CAS RN 157212-55-0), bosentan sodium (CAS RN 150726-52-6), bosentan potassium (CAS RN Not Available), bosentan citrate (CAS RN Not Available), bosentan calcium (CAS RN Not Available), bosentan oxalate (CAS RN Not Available), bosentan hydrogensulphate (CAS RN Not Available), bosentan tartarate (CAS RN Not Available), and bosentan hydrochloride (CAS RN Not Available). Bosentan is used to treat pulmonary arterial hypertension (PAH, high blood pressure in the vessels that carry blood to the lungs). Bosentan may improve the ability to exercise and slow the worsening of symptoms in patients with PAH. Bosentan is in a class of medications called endothelin receptor antagonists. It works by stopping the action of endothelin, a natural substance that causes blood vessels to narrow and prevents normal blood flow in people who have PAH. 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.
