Tracleer® (bosentan) is a prescription medicine approved to treat a type of high blood pressure called pulmonary arterial hypertension (PAH). Tracleer helps treat this condition by preventing the blood vessels in the lungs from constricting (narrowing).
Clinical studies showed that people who took Tracleer were able to walk farther over a six-minute period than people who did not take bosentan (the six-minute walk test is a commonly used test to assess how much a person's PAH symptoms are limiting their ability to exercise). The medication also slows down how quickly the condition and symptoms get worse.
