What is the proper dosage for Infasurf?

Infasurf, a natural pulmonary surfactant derived from porcine lung fluid, is used primarily for the treatment of neonatal respiratory distress syndrome. The proper dosage for Infasurf is 3 ml/kg, which is based on clinical guidelines for administering surfactant therapy to neonates, particularly those who are preterm and have developed this condition.

The dosage of 3 ml/kg is established to optimize lung function by improving alveolar stability, thereby reducing surface tension in the alveoli and preventing collapse. Administering the correct dosage is crucial for effective treatment and minimizing potential side effects. Excessive dosing can lead to complications, while underdosing may not provide the intended therapeutic effect. Hence, the 3 ml/kg guideline is supported by clinical studies that focus on the balance of efficacy and safety in treating respiratory distress syndrome in neonates.
