Abstract

The injection preparation for treating acute lung injury and acute respiratory distress syndrome is bacteria-free freeze dried powder for injection with Sivelestat as active component, stuffing frame agent, co-solvent and pH regulator. It has improved water solubility of Sivelestat and improved medicine stability.

Description

Technical field [0001] The invention relates to an injection for the treatment of acute lung injury and acute respiratory distress syndrome, specifically the English name is sivelestat Sodium Hydrate and the chemical name is N-[2-[4-(2,2-dimethylpropionic acid Yl)benzenesulfonamido]benzoyl]aminoacetate·tetrahydrate, the structural formula is The molecular formula is C 20 H 21 N 2 NaO 7 S·4H 2 O, a sterile freeze-dried powder injection with a molecular weight of 528.51 and the Chinese name of sivelestat. technical background [0002] Acute lung injury (ALI) / Acute Respiratory Distress Syndrome (ALI / ARDS) refers to acute and progressive hypoxic respiratory failure caused by various pathogenic factors inside and outside the lungs other than cardiogenic. ALI and ARDS have the same pathophysiological changes, and severe ALI or the final severe stage of ALI is defined as ARDS. The main pathological feature of ALI / ARDS is the formation of protein-rich pulmonary edema and hyaline membran...
