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.
