Quinolone antibacterial drugs inhibit bacterial DNA helicase and have a broad-spectrum antibacterial effect. They have strong antibacterial activity against Enterobacter bacteria such as Escherichia coli, Klebsiella, Proteus, Shigella, Salmonella typhi, etc., as well as influenza bacillus and Neisseria. They also have certain antibacterial effects on Staphylococcus aureus and Pseudomonas aeruginosa. They have only mild effects on pneumococci, various groups of streptococci and enterococci.

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. This product has the characteristics of a broad antibacterial spectrum and strong antibacterial effect. It has strong antibacterial activity against most Enterobacteriaceae, such as Klebsiella pneumoniae, Proteus, Salmonella typhi, Shigella, and some Escherichia coli. It also has good antibacterial effects on some Staphylococci, Streptococcus pneumoniae, Haemophilus influenzae, Pseudomonas aeruginosa, Neisseria gonorrhoeae, Chlamydia, etc.

Combined with pyrophosphate in the body to form a coenzyme. It participates in the oxidative decarboxylation reaction of pyruvate and α-ketoglutarate in sugar metabolism and is necessary for sugar metabolism. When it is deficient, oxidation is blocked to form pyruvate, lactic acid accumulates, and affects the body's energy supply. Its symptoms are mainly manifested in the nervous and cardiovascular systems, with multiple peripheral neuritis affecting both sensory nerves and motor nerves, manifested as paresthesia, neuralgia, limb weakness, muscle soreness and atrophy. In terms of cardiovascular, due to the increase of acetone and lactic acid in the blood, the small arteries are dilated, the diastolic pressure is reduced, and the myocardial metabolism is disturbed, so it is easy to have symptoms of heart failure such as palpitations, shortness of breath, chest tightness, cardiac hypertrophy, liver and lung congestion and peripheral edema. In terms of the digestive tract, it is manifested as weakness and weight loss caused by decreased appetite.
