Levofloxacin Hydrochloride Eye Drops

Levofloxacin is the levorotatory form of ofloxacin, and its antibacterial activity is about twice that of ofloxacin. Its main mechanism of action is to inhibit the activity of bacterial topoisomerase IV and DNA gyrase (both are type II topoisomerases), hindering the replication of bacterial DNA to achieve antibacterial effects. Levofloxacin has the characteristics of a broad antibacterial spectrum and strong antibacterial effect. It has strong antibacterial activity against most Enterobacteriaceae, such as Escherichia coli, Klebsiella, Serratia, Proteus, Shigella, Salmonella, Citrobacter, Acinetobacter, and Gram-negative bacteria such as Pseudomonas aeruginosa, Haemophilus influenzae, and Neisseria gonorrhoeae. It also has good antibacterial effects on some methicillin-sensitive Staphylococci, Streptococcus pneumoniae, Streptococcus pyogenes, hemolytic Streptococci, and Legionella, Mycoplasma, and Chlamydia, but has poor effects on anaerobic bacteria and enterococci.
