Tyvaso is a prescription drug approved by the U.S. Food and Drug Administration (FDA) to improve exercise capacity in cases of pulmonary arterial hypertension (PAH) and pulmonary hypertension associated with interstitial lung disease. Tyvaso may be referred to by its drug name, treprostinil.
Tyvaso is a prostaglandin. Prostaglandins are hormone-like compounds made by the body. Lower levels of prostaglandins are associated with narrowing of blood vessels in the lungs. Prostaglandins are believed to work in two ways. First, prostaglandins dilate the blood vessels of the lungs, increasing the blood flow and the amount of oxygen the cells receive. Second, prostaglandins help slow scarring in the blood vessels of the lungs, delaying the progress of the disease.
How do I take it?
Prescribing information states that Tyvaso is taken four times a day by inhalation.
Tyvaso comes in the form of ampules administered via the specialized Tyvaso inhalation system. The inhalation system must be newly assembled each day.
