Remodulin

Treprostinil injection is used to treat certain kinds of pulmonary arterial hypertension (PAH; high blood pressure in the vessels carrying blood to the lungs, causing shortness of breath, dizziness, and tiredness). Treprostinil injection is also used to treat PAH when another medication (epoprostenol) did not help or could not be tolerated. Treprostinil may improve the ability to exercise and slow the worsening of symptoms in patients with PAH. Treprostinil is in a class of medications called vasodilators and platelet-aggregation inhibitors. It works by relaxing the blood vessels, including those in the lungs, and improving blood flow.
