2018 International PH Conference and Scientific SeAbstract presented at the 2018 International PH Conference and Scientific Sessions in Orlando, Fla., June 28-July 1, 2018.


Pulmonary arterial hypertension (PAH) is a progressive, incurable disease with a rapidly progressing number of treatment options. Traditionally, prostacyclin therapies have been underutilized (1). Now with oral formulations available such as treprostinil, increased access to this important therapeutic pathway may improve patient outcomes, inclusive of quality of life and cost. (2,3) One strategy has been to transition patients from parenteral to oral prostacyclin therapy through a 5 day inpatient hospitalization regimen in 33 patients (4). We seek to describe our experience through a more rapid inpatient or outpatient based transition.


We retrospectively reviewed charts for those transitioned from parenteral to oral treprostinil within St. Vincent Medical Group in Indianapolis, IN between in 2017-18. Charts were extensively analyzed for baseline data, including transthoracic echocardiogram and hemodynamics, along with outcome analysis before and after treprostinil transition.


Six patients were transitioned from parenteral to oral prostacyclin therapy within a rapid 2-5 day observation admission or outpatient setting. Table 1 illustrates our 3 patients that have Group 1 pulmonary arterial hypertension on double or triple therapy with the prostacyclin. Transitions were safe and successful in all patients.


Based on our limited experience, it is safe to rapidly transition patients from parenteral to oral treprestinil in an outpatient fashion while maintaining functional status, ease of administration, cost and quality of life for the patient and health system.
