Description
Solid
Sitaxentan is a member of benzodioxoles.|Sitaxentan was marketed under the trade name Thelin for the treatment of pulmonary arterial hypertension (PAH) by Encysive Pharmaceuticals until Pfizer purchased Encysive in February 2008. In 2010, Pfizer voluntarily removed sitaxentan from the market over concerns of hepatotoxicity.
Drug Information
Investigated for use/treatment in pulmonary hypertension, connective tissue diseases, hypertension, and congestive heart failure.
Sitaxentan belongs to a class of drugs known as endothelin receptor antagonists (ERAs). Patients with PAH have elevated levels of endothelin, a potent blood vessel constrictor, in their plasma and lung tissue. Sitaxentan blocks the binding of endothelin to its receptors, thereby negating endothelin's deleterious effects.
Compounds and drugs that bind to and inhibit or block the activation of ENDOTHELIN RECECPTORS. (See all compounds classified as Endothelin Receptor Antagonists.)

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.
