Direct prostacyclin transition in pediatric patients with pulmonary hypertension

Abstract

AbstractPediatric patients with pulmonary arterial hypertension (PAH) are commonly treated with the prostacyclin analog treprostinil in IV, SQ, inhaled or oral form, or the prostacyclin receptor agonist selexipag. Patients who transition between these medications often follow recommendations for gradual up‐ and down‐titrations that take place over several days in the hospital or several weeks as an outpatient. However, hospital resources are limited, and long transitions are inconvenient for patients and families. We report a case series of eight pediatric patients with PAH transitioned directly between prostacyclins with no overlapping doses. Direct medication transitions occurred in the cardiac intensive care unit (CICU), at home and in cardiology clinic. Equivalent doses for selexipag were estimated using information extrapolated from experience, published materials and selexipag study guidelines. All patients completed direct transition as planned and remained on transition dose for at least 1 week. In most cases selexipag was up‐titrated at home after establishing initial transition dose. In select patients, direct prostacyclin transition in pediatric patients with PAH is safe, effective, convenient for families and reduces the use of hospital resources.
