This product is the levorotatory form of ofloxacin, and its antibacterial activity is about 2 times that of ofloxacin. Its main mechanism of action is to inhibit bacterial DNA gyrase activity and inhibit bacterial DNA replication. It has the characteristics of broad antibacterial spectrum and strong antibacterial effect. It has strong antibacterial activity against most Enterobacteriaceae, such as Klebsiella pneumoniae, Proteus, Salmonella typhi, Shigella, influenza bacillus, some Escherichia coli, Pseudomonas aeruginosa, gonococci, etc. It also has good antibacterial effect against some Staphylococci, Streptococcus pneumoniae, Chlamydia, etc.
