Treprostinil inhalation solution
Generic Name: treprostinil (tre-PROST-i-nil)
Brand Name: Tyvaso
Treprostinil inhalation solution is used for:
Treating pulmonary arterial hypertension (PAH) (high blood pressure in the arteries of the lungs) in certain patients to increase walk distance. It may also be used for other conditions as determined by your doctor.
Treprostinil inhalation solution is a prostacyclin vasodilator. It works by relaxing blood vessels and increasing the supply of blood to the lungs in patients with high blood pressure in the lungs. This decreases how hard the heart must work to pump blood to the lungs. It also prevents the platelets in your blood from clotting to prevent unwanted blood clots.
