Tyvaso is a prescription drug approved by the Food and Drug Administration (FDA) to improve exercise capacity in cases of pulmonary arterial hypertension (PAH). Tyvaso may be referred to by its drug name, Treprostinil.

Tyvaso is a prostaglandin. Prostaglandins are hormone-like compounds made by the body. In cases of PAH, prostaglandins are believed to work in two ways. First, prostaglandins dilate the blood vessels of the lung, increasing the blood flow and the amount of oxygen the cells receive. Second, prostaglandins help slow scarring in the blood vessels of the lungs, slowing the progress of the disease and potentially even reversing some damage.
