Abstract
Description
technical field
[0001] The invention belongs to the technical field of biomedical engineering, and in particular relates to a prescription of a recombinant human brain natriuretic peptide injection preparation and a preparation method thereof. Background technique
[0002] Protein instability mainly includes chemical instability and physical instability. Chemical instability leads to protein modification through bond formation or breakage, mainly including deamidation, racemization, hydrolysis, oxidation, β-elimination and binary Sulfur bond breaking or exchange, etc. Physical instability will not lead to covalent changes in proteins, but changes in higher-order structures (secondary structures and above) of proteins, mainly including denaturation, adsorption, aggregation, and precipitation. The purpose of research on the prescription of protein drug preparations is to stably prolong the storage time of protein drugs on the basis of maintaining the natural and pharmaceutical...
