Abstract
Parenteral prostacyclin therapy is first-line for Group 1 pulmonary arterial hypertension patients with severely limited functional status. There are two current pharmacologic options in this realm, intravenous epoprostenol and intravenous or subcutaneous treprostinil. In this chapter, we will discuss similarities and differences between the two formulations, present practical knowledge for prescribing these therapies, and outline the current indications and the data supporting those recommendations. We will dissect the components of the clinical trials that exist in this realm and controversies therein. Lastly, we will discuss the timing of initiation of therapy, as well as patient-focused concerns and challenges with parenteral therapy.
