PAH

WHAT CAUSES PAH? WHAT IS PROSTACYCLIN? HOW TYVASO CAN HELP

What Causes PAH and Its Symptoms?

People with pulmonary arterial hypertension (PAH) have an imbalance of one or more of 3 natural substances in the body:

When these 3 substances are out of balance, blood vessels in the lungs narrow, requiring the right side of the heart to work even harder to pump blood to the lungs.

This can cause symptoms like shortness of breath and fatigue, which may make it difficult to do daily activities. Because PAH is a progressive disease, you may find yourself becoming less active over time.

Healthy vessel: Blood can be pumped easily from the heart to the lungs.

Side by side: healthy vessel, vessel with PAH.

Vessel with PAH: Narrow vessels slow down the flow of blood and make the heart work harder to pump blood to the lungs.

Side by side: healthy vessel, vessel with PAH.

There are medicines that treat each of those 3 imbalances, or pathways, associated with PAH. Each PAH medicine targets only one of those pathways.

What Is Prostacyclin? [pra·stuh·si·klin]

Prostacyclin is one of the 3 pathways associated with PAH that helps ensure blood vessels are healthy and stay open. People with PAH may not produce enough prostacyclin in their lungs.

What Is the Function of Prostacyclin?

The function of prostacyclin is to help keep blood flowing through your lungs by:

  • Widening or opening narrow blood vessels
  • Preventing clotting
  • Slowing down the thickening of blood vessels

TYVASO helps replace and mimics the effects of the natural prostacyclin you may be missing.
