This product has a broad-spectrum antibacterial effect, especially high antibacterial activity against aerobic Gram-negative bacilli. It has good antibacterial activity in vitro against the following bacteria: most bacteria of the Enterobacteriaceae family, including Citrobacter, Enterobacter cloacae, Enterobacter aerogenes, Escherichia coli, Klebsiella, Proteus, Salmonella, Shigella, Vibrio, Yersinia, etc. It often has antibacterial activity against multi-drug resistant bacteria. It has high antibacterial activity against penicillin-resistant Neisseria gonorrhoeae, enzyme-producing Haemophilus influenzae and Moraxella. It has antibacterial activity against most strains of Pseudomonas such as Pseudomonas aeruginosa. This product has antibacterial activity against methicillin-sensitive Staphylococcus aureus, and only moderate antibacterial activity against Streptococcus pneumoniae, hemolytic Streptococcus and Enterococcus faecalis. It has good antimicrobial activity against Chlamydia trachomatis, Mycoplasma, Legionella, and also has antibacterial activity against Mycobacterium tuberculosis and atypical mycobacteria. Poor antibacterial activity against anaerobic bacteria. Ofloxacin is a bactericide that acts on the A subunit of bacterial DNA helicase, inhibiting DNA synthesis and replication, leading to bacterial death.

The antibacterial property is similar to that of erythromycin. It has a strong antibacterial effect on Gram-positive bacteria, and is effective against Staphylococcus, Streptococcus pyogenes, Streptococcus viridans, Streptococcus pneumoniae, Diphtheria bacillus, Tetanus bacillus, and anthrax bacillus. It also has antibacterial effects on Gram-negative bacteria such as gonococci and pertussis bacillus. It is also effective against Leptospira, Rickettsia, and Mycoplasma. It can be used as a substitute for erythromycin for infections of the oropharynx, respiratory tract, skin and soft tissue, and bile duct caused by the above-mentioned sensitive bacteria.
