Method for preparing glycyrrhizinate lipid ligand for injection

The invention belongs to the technical field of preparation of medicines and aims to provide a method for preparing a glycyrrhizinate lipid ligand for injection. The method has the characteristics of simple technology and stable and reliable quality of obtained products. The method for preparing the glycyrrhizinate lipid ligand for injection comprises the following steps: (1) preparing a colloidal dispersion system; (2) adding active carbon into the prepared colloidal dispersion system to adsorb pyrogen and decolorize, filtering and removing the active carbon, filtering filter liquor by a microporous filter film till medicine liquid is clear; (3) normally sterilizing the filtered glycyrrhizinate lipid ligand for injection and preparing and obtaining injection or infusion or freeze-dried powder injection according to a normal technology.
