The present invention provides a composition of Pefloxacin Mesylate For Injection freeze-dried powder, involving drugs and drug manufacturing technology, contains the following ingredients: weight of pefloxacin mesylate was 7.26 ~ 9.17, 5.45 ~ 6.84 chitosan nanoparticles, 83.99 to 89.29 parts of water for injection. The invention has the advantages that: 1) the composition can significantly increase the antibacterial activity of pefloxacin mesylate to Klebsiella, Enterobacter and Sarre. 2) chitosan nanoparticles are small in size and can overcome the biological barrier through the finest capillaries to avoid rapid clearance of macrophages. Therefore, the duration of the composition in the blood is greatly prolonged. 3) chitosan nanoparticles can replace mannitol as a freeze-dried matrix for freeze-dried powder, thus eliminating the effect of mannitol on human body.
