Mechanism of action

Poractant alfa is an extract of porcine lung surfactant containing phospholipids and surfactant-associated proteins that mimics endogenous pulmonary surfactant. It is administered intratracheally to replace deficient or dysfunctional surfactant in premature infants, thereby reducing alveolar surface tension, preventing alveolar collapse, and improving lung compliance and gas exchange.
