Overview
DESCRIPTION SURVANTA ® contains beractant, a pulmonary surfactant, which is a natural bovine lung extract containing phospholipids, neutral lipids, fatty acids, and surfactant-associated proteins (SP) to which colfosceril palmitate (dipalmitoylphosphatidylcholine), palmitic acid, and tripalmitin are added to standardize the composition and to mimic surface-tension lowering properties of natural...
Mechanism of Action
CLINICAL PHARMACOLOGY 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. Activity 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 surfactant-deficient.
Indications
- INDICATIONS AND USAGE SURVANTA is indicated for prevention and treatment (“rescue”) of Respiratory Distress Syndrome (RDS) (hyaline membrane disease) in premature infants.
Common Doses
- 100 mg
- 4 mL
Dosage
DOSAGE AND ADMINISTRATION Important Administration Instructions For intratracheal administration only. SURVANTA should be administered by or under the supervision of clinicians experienced in intubation, ventilator management, and general care of premature infants. The administration of SURVANTA is facilitated if one person administers the dose while another person positions and monitors the infant. Before administering SURVANTA, assure proper placement and patency of the endotracheal tube.
Contraindications
- CONTRAINDICATIONS None
Side Effects
- ADVERSE REACTIONS The most commonly reported adverse experiences were associated with the dosing procedure. In the multiple-dose controlled clinical trials, each dose of SURVANTA was divided into four quarter-doses which were instilled through a catheter inserted into the endotracheal tube by briefly disconnecting the endotracheal tube from the ventilator. Transient bradycardia occurred with 11.9% of doses . Oxygen desaturation occurred with 9.8% of doses .
Interactions
- No major interactions listed on the FDA label. Always consult a healthcare professional.
