Beractant
Beractant, also known by the trade name of Survanta, is a modified bovine pulmonary surfactant containing bovine lung extract (phospholipids, neutral lipids, fatty acids, and bovine surfactant proteins), to which synthetic DPPC, tripalmitin and palmitic acid are added. The composition provides 25 mg/mL phospholipids, 0.5 to 1.75 mg/mL triglycerides, 1.4 to 3.5 mg/mL free fatty acids, and <1.0 mg/mL total surfactant proteins. As an intratracheal suspension, it can be used for the prevention and treatment of neonatal respiratory distress syndrome.
