| Description | Beractant is a pulmonary surfactant made from natural bovine lung extract. |
| Indication/Disease | Beractant is indicated for Respiratory Distress Syndrome (RDS) in premature infants. |
| Pharmacodynamics | Endogenous pulmonary surfactant lowers surface tension on alveolar surfaces during respiration and stabilizes the alveoli against collapse at resting transpulmonary pressures. Deficiency of pulmonary surfactant causes Respiratory Distress Syndrome (RDS) in premature infants. SURVANTA replenishes surfactant and restores surface activity to the lungs of these infants. |
| Mechanism of Action | In vitro, SURVANTA reproducibly lowers minimum surface tension to less than 8 dynes/cm as measured by the pulsating bubble surfactometer and Wilhelmy Surface Balance. In situ, SURVANTA restores pulmonary compliance to excised rat lungs artificially made surfactantdeficient. In vivo, single SURVANTA doses improve lung pressure-volume measurements, lung compliance, and oxygenation in premature rabbits and sheep. |
| Toxicity | NA |
| Metabolism | In surfactant-deficient premature rabbits and lambs, alveolar clearance of radio-labelled lipid components of beractant is rapid. Most of the dose becomes lung-associated within hours of administration, and the lipids enter endogenous surfactant pathways of reutilization and recycling. Limited animal experiments have not found effects of beractant on endogenous surfactant metabolism. |
| Absorption | Beractant is administered directly to the target organ, the lungs, where biophysical effects occur at the alveolar surface. |
