Abstract
Two prostacyclins (prostaglandin E1 and prostaglandin I2) are potent vasodilators. Aerosolized prostacyclins reduce pulmonary artery pressure, improve right heart function, and increase arterial oxygenation by improving ventilation/perfusion matching. This report describes aerosolized prostacyclins and compares them to inhaled nitric oxide. I review the types of inhalable prostacyclins and their indications, evidence of efficacy, delivery, and adverse effects.
