It has high activity against protozoa and anaerobic bacteria, and can inhibit most anaerobic bacteria; microaerophilic bacteria and Helicobacter pylori are sensitive to it; the mechanism of anti-amoeba is to inhibit its redox reaction, break the nitrogen chain of the protozoa, and thus kill the protozoa. Its nitro group is reduced to a cytotoxin, which acts on the DNA metabolism process of bacteria and promotes the death of bacteria.

This product is a quinolone antibacterial drug, which has strong antibacterial effect on Gram-negative bacteria, including Escherichia coli, Klebsiella pneumoniae, Proteus, Salmonella typhi, Salmonella paratyphi, Shigella, Enterobacter cloacae, Enterobacter aerogenes, Citrobacter, Serratia marcescens, Pseudomonas aeruginosa, Neisseria meningitidis, Haemophilus influenzae, Moracata, Legionella pneumophila, Neisseria gonorrhoeae, etc. It also has moderate antibacterial effect on Gram-positive cocci such as Staphylococcus and hemolytic Streptococcus. The mechanism of action of this product is to inhibit the bacterial DNA gyrase and thus kill the bacteria.

It has a direct inhibitory effect on respiratory syncytial virus (RSV) and a direct inactivation effect on influenza virus A1 and A3. It has no local irritation and hemolysis in vivo. The LD50 of intravenous injection in mice is 122.14±41.44mg/kg; the LD50 of oral gavage in mice is 147.0g/kg; the LD50 of intramuscular injection is 55g/kg; the maximum tolerance and minimum lethal dose in mice are 48 and 49g/kg respectively. No accumulation effect is observed after six consecutive days of medication.

This product is a brain metabolism improving drug, which is a cyclic derivative of г-aminobutyric acid. It has the effect of resisting brain function damage caused by physical and chemical factors. It can promote the generation of ATP in the brain, promote the synthesis of acetylcholine and enhance the conduction of nerve excitement, and has the effect of promoting brain metabolism. It can resist brain function damage caused by physical and chemical factors. It has an improving effect on retrograde amnesia caused by hypoxia. It can enhance memory and improve learning ability.
