Abstract

Introduction: Pulmonary arterial hypertension is an increasingly recognized heterogeneous disease with significant morbidity and mortality, requiring a multimodal approach to treatment. Inhalation administration of treprostinil sodium (Tyvaso®) permits higher local drug concentration without some of the side effects of parenteral prostanoids. Areas covered: After a broad discussion centering on available prostacyclins, a thorough literature review of treprostinil is undertaken, focusing on the timeline of clinical studies, specifically highlighting the major trials that shape current indications and usage. The literature search was undertaken via multiple search engines and strategies with review of cited and associated articles to provide a comprehensive discussion on the topic. Expert opinion: While safe and well tolerated, inhaled treprostinil sodium should be limited, based on available data, to use as add-on therapy for patients with Group I pulmonary hypertension not effectively controlled on oral therapy. Despite documented safety for the conversion from inhaled iloprost to inhaled treprostinil, the transition of patients stable on parenteral agents to inhaled treprostinil should be cautioned due to the potential for clinical decompensation. © 2014 Informa UK, Ltd.

Dr. Richard Krasuski is Director of the Adult Congenital Heart Center at Duke University Medical Center, the Director of Hemodynamic Research, and the Medical Director of the CTEPH Program. He is considered a thought leader in the fields of pulmonary hypertension and congenital heart disease. His research focus is in epidemiologic and clinical studies involving patients with pulmonary hypertension and patients with congenital heart disease. He is involved in multiple multicenter studies through the Alliance for Adult Research in Congenital Cardiology (AARCC). He has also helped to develop multiple research databases in these patient populations. He is Co-PI in the upcoming EPIPHANY Study examining the impact of medical and transcatheter interventions on RV-PA coupling in patients with chronic thromboembolic pulmonary hypertension. Over his career he has mentored over 80 students, residents and fellows and has published over 300 peer reviewed publications, book chapters and meeting abstracts. He is also the Chief Editor of Advances in Pulmonary Hypertension and on the editorial boards of several leading medical journals.
