Orenitram
What is Orenitram?
Orenitram is an oral prostacyclin-class medicine that has been shown to help slow down the progression of PAH. It also helps improve exercise ability and decrease the symptoms of PAH. With Orenitram, there is information available for your healthcare team about how patients stable on pump therapy (treprostinil) transitioned to oral therapy. It is not known if Orenitram is safe and effective in children under 18 years of age.
Similar medicine as in a pump, but in a tablet
Orenitram is the only pill that gives you the same type of medicine (active ingredient) that is available in pump therapy. In a small study,† patients in the hospital stable on pump therapy (treprostinil) successfully switched to Orenitram while maintaining their 6-minute walk distance and right heart catheterization results.
†An open-label, uncontrolled (no placebo) study of 33 hospitalized patients with PAH.
Orenitram may help you reach your goals
Because Orenitram is an oral option, you may enjoy activities like being in the pool or taking a bath. Adding Orenitram has been shown to improve many measures of PAH symptoms and function, including:
- Helping to slow down the worsening of PAH
- Improving the ability to walk farther, as measured by six-minute walk distance
- Improving heart function (in the right ventricle)
- Improving the ability to do more physical activity, as measured by functional class
- Reducing shortness of breath
- Decreasing the risk of PAH getting worse (ie, improving risk status)
If you have been diagnosed recently or have had PAH for some time, Orenitram may be right for you.

Expectations
Pulmonary Arterial Hypertension is a serious condition. The medications designed to fight the disease typically show benefit slowly, over months, with most needing 4 to 6 months for maximum effect. The adverse effects (Side-effects) of these medications, however happen upfront. Your body typically will get used to them either with time, or with additional natural remedy or drugs. This may also take 2 to 3 months. It is necessary that you have patience, and talk to your doctor or nurses about dealing with them. Sometimes slowing the planned increase or cutting down on medication for a while will allow your body to adjust. Discuss matters with your doctors’ office before taking action of your own. Patience is a virtue!
