Poractant alfa
Poractant alfa
Poractant alfa (pronunciation: por-AK-tant AL-fa) is a type of pulmonary surfactant used in the treatment of respiratory distress syndrome (RDS) in premature infants.
Etymology
The term "poractant alfa" is derived from the Latin porcus meaning pig, and actant referring to an active substance. The alfa denotes the first version of this drug. It is so named because it is derived from the lung tissue of pigs.
Usage
Poractant alfa is used to treat or prevent respiratory distress syndrome (RDS) in premature infants. It is administered directly into the infant's lungs through a breathing tube. The drug works by lowering the surface tension of the lungs, which helps the infant to breathe more easily.
Related Terms
- Pulmonary surfactant: A substance that decreases surface tension within the alveoli in the lungs, preventing collapse and increasing the ability to exchange gases such as oxygen and carbon dioxide.
- Respiratory distress syndrome (RDS): A breathing disorder that affects newborns, especially those who are premature. RDS is caused by a lack of surfactant in the lungs.
- Premature birth: A birth that takes place more than three weeks before the baby's estimated due date. Premature infants are at higher risk of developing RDS.
