Calfactant, also known as Infasurf,[1] is an intratracheal suspension derived from the natural surfactant in calf lungs. It is used in premature infants with lung surfactant deficiency that causes infant respiratory distress syndrome (IRDS).[2]

Mechanism of action
Lung surfactant is essential for effective ventilation as it modifies alveolar surface tension.[3] IRDS is caused by a lung surfactant deficiency. Calfactant serves as a substitute for the natural surfactant.[2]
