People with PAH may not produce enough natural prostacyclin

Prostacyclin is essential for proper lung function. At normal levels, prostacyclin helps keep vessels in the lungs healthy and open, allowing blood to flow freely. Patients with PAH may not produce enough prostacyclin. Without enough prostacyclin, vessels in the lungs become narrow and blood doesn't flow as easily.

If your treatment plan does not include a medicine to address the prostacyclin pathway, learn more and talk to your doctor about how a prostacyclin analog may help

UT's PROSTACYCLIN ANALOGs mimic some of the effects of the body's natural prostacyclin

These medicines are considered prostacyclin analogs, man-made forms of prostacyclin that help address the body's lack of prostacyclin
