Sinapultide（Cat No.:M111596）is a synthetic peptide mimicking the lung surfactant protein B, crucial for treating respiratory distress syndrome (RDS). By enhancing lung surface tension, it facilitates better gas exchange and prevents alveolar collapse. Sinapultide’s stability and efficacy make it a vital component in neonatal care, significantly improving outcomes in premature infants with underdeveloped lungs. Its precise formulation ensures reproducibility and reliable therapeutic results. Widely researched, Sinapultide continues to be a cornerstone in respiratory medicine, offering hope and improved quality of life for patients with RDS and other pulmonary conditions.
