商品名：Noroxin
Fluoroquinolone antibacterial drug. Norfloxacin acts via inhibition of DNA gyrase in bacteria to inhibit DNA and RNA synthesis. It is a bactericidal with a broad spectrum of activity. Sensitive bacteria include Staphylococcus, Escherichia coli, Proteus, Klebsiella, and Pasteurella. Pseudomonas aeruginosa is moderately sensitive. However, norfloxacin is not as active as other drugs in the fluoroquinolone group.
Norfloxacin has been replaced by other veterinary fluoroquinolones because they have more favorable pharmacokinetics and improved spectrum of activity. However, it has been used to treat a variety of infections, including respiratory, urinary tract, skin, and soft tissue infections.
