Azithromycin lactobionateinjection solution packaged by double-cavity bag and preparation method

The invention discloses an azithromycin lactobionateinjection injection solution packaged by double-cavity bag. The medicinal composition of the injection solution comprises the following raw materials: 0.1-0.3 parts by weight of azithromycin lactobionateinjection in a powder cavity, and 4-11 parts by weight of glucose injection solution with 100 parts by volume of glucose or 0.8-1 parts by weight of sodium chloride injection solution with 100 parts by volume of sodium chloride in a solution cavity. The azithromycin lactobionateinjection injection solution is packaged by a double-cavity bag; sterilized azithromycin lactobionateinjection powder and solvent (sodium chloride injection solution or glucose injection solution) are filled in two cavities separated by pseudo soldering separations respectively; and when the azithromycin lactobionateinjection injection solution is used, pseudo soldering isolating bars can be connected by extruding a medicine bag only, and the sterilized azithromycin lactobionateinjection powder and the solvent are quickly solved and mixed under the sealed and sterilized condition to form a total medicine treatment mixed solution which can be directly applied to the patient.
