Treprostinil Dry Powder Inhaler (DPI)

What is this medication?

TREPROSTINIL (tre PROST in il) treats pulmonary arterial hypertension (PAH), a condition that causes high blood pressure in the lungs. It works by relaxing the blood vessels and lowering the blood pressure in the lungs, which makes it easier for the heart to pump blood to the rest of the body. It can help you breathe easier and be more active.
