Sitaxentan 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, Sitaxentan decreases pulmonary vascular resistance. Sitaxentan has a higher affinity for ET-A than ET-B.
Investigated for use/treatment in pulmonary hypertension, connective tissue diseases, hypertension, and congestive heart failure.
