Letairis (ambrisentan) is a prescription medication used to treat pulmonary arterial hypertension (PAH). It is a type of drug known as an endothelin receptor antagonist (ERA). It works by blocking the action of endothelin, a substance in the body that can cause the blood vessels in the lungs to narrow. This narrowing can lead to high blood pressure in the lungs, which can cause shortness of breath, fatigue, and other symptoms. Letairis is used to reduce the symptoms of PAH and improve exercise capacity. Letairis is marketed by Gilead Sciences, Inc. in the United States and by Actelion Pharmaceuticals Ltd. in Europe. It is available in tablet form and is taken orally once a day. It is usually taken with food. The Letairis market is a subset of the larger cardiovascular drugs market. It is a relatively small market, but it is growing due to the increasing prevalence of PAH. Some companies in the Letairis market include Gilead Sciences, Inc., Actelion Pharmaceuticals Ltd., GlaxoSmithKline, Bayer AG, and Novartis AG. Show Less Read more
