How Tyvaso Works

Tyvaso is an inhaled prostacyclin analogue used to treat pulmonary arterial hypertension (PAH) (WHO Group 1). People with PAH have too little prostacyclin in their bodies. Tyvaso mimics some of the effects of natural prostacyclin in the body. It opens up pulmonary arteries, allowing blood to flow more easily. Prostacyclin also helps to keep pulmonary arteries open and working properly, so there is less stress on the heart.

How it works

  1. Tyvaso is inhaled directly into the lungs.
  2. It dilates, or opens up, the arteries between the lungs and heart.
  3. It prevents blood platelets from clumping together.
  4. It allows the heart to pump blood more easily into the lungs.
