Ambrisentan, sold under the brand name Letairis among others, is a drug used for the treatment of pulmonary hypertension. It is an endothelin receptor antagonist.

The peptide endothelin constricts muscles in blood vessels, increasing blood pressure. Ambrisentan, which relaxes those muscles, is an endothelin receptor antagonist, and is selective for the type A endothelin receptor (ETA). Ambrisentan significantly improved exercise capacity (6-minute walk distance) compared with placebo in two double-blind, multicenter trials (ARIES-1 and ARIES-2). Like all endothelin receptor antagonists, Ambrisentan is contraindicated in pregnant women as well as those who are trying to become pregnant, due to the potential for teratogenic effects on the fetus.
