Tyvaso Inhalation System

Direct-to-the-lungs Delivery

TYVASO is delivered noninvasively, directly to the lungs.1 Ultrasonic nebulizers deliver treprostinil directly to distal airspaces that are in close proximity to pulmonary arterioles affected in PAH.2

The TYVASO Inhalation System uses uniform particle size (mean 2.0 μm) for treprostinil delivery.2-4
