Abstract

The present invention relates to a container-holding mesylate pazufloxacin aqueous solution. The mesylate pazufloxacin aqueous solution is stored in a container with a seal, and is characterized in that the pH of the aqueous solution is in the range of 1-4, the concentration of mesylate pazufloxacin in the aqueous solution is 0.001-0.01 g / ml, the container is sealed by complex membrane or a coating film rubber stopper, and the film used by the complex membrane or the coating film rubber stopper is fluoro-polymer film, poly-p-xylene-containing film or composite polyethylene glycol terephthalate film. The present invention solves the problem that visible foreign matter appears in the mesylate pazufloxacin injection products during placement.
