Fleroxacin is a drug from the group of quinolone antibiotics , more precisely the fluoroquinolone antibiotics . It was the first time in 1981 by Kyorin patented and is in the form of mono hydrochloride used. In Germany, the drug was on the market from 1995 to 2003 under the name Quinodis .
properties
The antimicrobial spectrum includes a number of gram-negative germs, including Enterobacteriaceae such as Klebsiella , E. coli , Salmonella , Shigella and Yersinia as well as Haemophilus and Neisseria , and Fleroxacin is also very effective against many staphylococci . It is less effective against Pseudomonas , but largely ineffective against streptococci and enterococci .
use
Fleroxacin is one of the fluoroquinolones with a wide range of indications. It can be administered either orally or parenterally, with a single dose usually being sufficient. It can be used to treat infections of the lower urinary tract, respiratory tract, and skin, among other things. Compared to other antibiotics, the use of Fleroxacin led to an increased incidence of undesirable effects after the market launch , which led to the drug being withdrawn from the market.
Pharmacokinetics
After oral administration, the substance is rapidly and almost completely absorbed ; maximum plasma levels occur after 1 to 2 hours. The half-life is 10 to 12 hours, which is why a single dose per day is sufficient. Most of the excretion is renal , i.e. H. through the kidneys.
