Quick Summary

Fluoroquinolones are a group of fluorinated derivatives of quinolone used as antibacterial drugs. They were first developed in 1984.

Fluoroquinolones work by interfering with bacterial DNA synthesis, which is a crucial step in bacterial reproduction. This mechanism makes them effective against a range of bacterial infections, including those of the respiratory and urinary tracts, skin, eyes, and bone and joints. Examples of fluoroquinolones include ciprofloxacin and norfloxacin.1

It is important to note that bacteria can develop resistance to antibiotics, including fluoroquinolones, which can make infections harder to treat.1

Thus, fluoroquinolones such as ciprofloxacin, the aminocyclitol antibiotic spectinomycin, and cephalosporins such as cefoxitin became increasingly used as alternatives for eliminating N. gonorrhoeae. Some strains of the bacteria, however, later developed resistance to fluoroquinolones, and eventually multidrug-resistant strains appeared. In the early 2000s, evidence
