Review: Surfactant respiratory therapy using Surfaxin/sinapultide

Respiratory distress syndrome (RDS) is a leading cause of mortality and morbidity in preterm infants. Surfactant replacement therapy has been widely used to prevent and treat RDS in these newborns and has now become a standard of care. First-generation synthetic surfactants such as Exosurf did not contain any surfactant protein. This disadvantage was overcome with animal-derived surfactant preparations which contain specific proteins but has the limitation of being derived from animal sources. This has led to development of newer synthetic surfactants such as lucinactant (Surfaxin, Discovery Laboratories, Philadelphia) which contains the protein B mimic synthetic peptide, sinapultide. Recent phase 3 clinical trials with Surfaxin show promising results with similar efficacy as animal derived surfactants and yet avoiding the disadvantage associated with animal products. The purpose of this paper is to summarise results of recent clinical trials of Surfaxin use in newborns with RDS.
