Two prostacyclins (prostaglandin E(1) and prostaglandin I(2)) 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.

Despite advances in therapy, asthma continues to be the chronic condition most responsible for school absenteeism and pediatric hospitalizations. This is especially true for inner-city children. We operate an inner-city Pediatric Asthma Compliance and Technique (PACT) clinic in which physicians and respiratory therapists collaborate to improve metered-dose inhaler (MDI) technique and outcomes among asthmatic children. ⋯ In our PACT clinic asthmatic children showed sustained improvement in MDI technique, and some of the patients improved in pulmonary function and overall asthma severity score.
