It achieves its antibacterial effect by inhibiting the activity of bacterial DNA gyrase and hindering bacterial replication. It has good antibacterial effects on most Enterobacteriaceae, some Gram-positive bacteria, Legionella, Mycoplasma, Chlamydia, etc., but has poor effects on anaerobic bacteria and enterococci.

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, and only has moderate antibacterial activity against Streptococcus pneumoniae, hemolytic Streptococcus and Enterococcus faecalis. It has good antimicrobial effect 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.

Proton pump inhibitor. This product is a fat-soluble weakly alkaline drug that is easily concentrated in an acidic environment. Therefore, after oral administration, it can be specifically distributed in the secretory tubules of the gastric mucosal parietal cells and converted into the active form of sulfenamide in this high-acid environment. It then irreversibly combines with the sulfhydryl group of the H,K-ATPase (also known as the proton pump) in the secretory membrane of the parietal cells through a disulfide bond to form a complex of sulfenamide and the proton pump, thereby inhibiting the activity of the enzyme and blocking the final step of gastric acid secretion. Therefore, this product has a strong and lasting inhibitory effect on gastric acid secretion caused by various reasons.
