Why is this medication prescribed?

Orenitram (generic name: treprostinil) is a medication that is prescribed for the treatment of pulmonary arterial hypertension (PAH). PAH is a condition characterized by high blood pressure in the arteries of the lungs, which can lead to various symptoms such as shortness of breath, fatigue, chest pain, and difficulty exercising. Orenitram belongs to a class of medications called prostacyclin analogs, which help to dilate the blood vessels and improve blood flow in the lungs.

Orenitram is typically prescribed to adults with PAH who are classified as World Health Organization (WHO) functional class II-III. It is used to improve exercise capacity and delay disease progression. It is not a cure for PAH, but it can help manage the symptoms and improve quality of life.
