    Fluoroquinolone use and chloroquine resistance development


    According to legend it was first brought to Europe by a Countess who had been treated with it in Peru in the 1600s. In 1820, two French chemists isolated quinine from the cinchona bark and quinine became a treatment of reference for intermittent fever throughout the world. Quinine remains an important and effective treatment for malaria today, despite sporadic observations of quinine resistance.

    Introduction. Quinolones have been a widely used class of synthetic antimicrobials. 1, 2 The initial member of the class, nalidixic acid, was identified as a byproduct of chloroquine synthesis in 1962 and had limited clinical use because it was only sufficient for treatment of urinary tract infections and because of the early emergence of resistance. 3 Chemical modifications of the core. S typhimurium with decreased susceptibility to fluoroquinolones and Campylobacter resistant to fluoroquinolones have been isolated from animals and retail poultry. 10,11 For these reasons the use of fluoroquinolones in veterinary medicine has caused concern, as such strains can infect man. A fluoroquinolone is often the drug of choice for. Fluoroquinolones also have been associated with the development of bacterial resistance and Clostridium difficile-associated diarrhea. The benefits of the fluoroquinolones e.g. broad spectrum of activity and high oral bioavailability and the risks of potential undesired side effects must be considered at the point of prescribing.

    These compounds belonged to a new class of antimalarials, the four-amino quinolines. Research by German scientists to discover a substitute for quinine led to the synthesis in 1934 of Resochin (chloroquine) and Sontochin (3-methyl-chloroquine).

  6. Because the use of broad-spectrum antibiotics encourages the spread of multidrug-resistant strains and the development of Clostridium difficile infections, treatment guidelines often recommend minimizing the use of fluoroquinolones and other broad-spectrum antibiotics in less severe infections and in those in which risk factors for multidrug resistance are not present.

    The discovery of nalidixic acid in 1962, and its introduction for clinical use in 1967, marks the beginning of five decades of quinolone development and use. The notion that fluoroquinolone therapy can be “targeted” for an indication requires challenge as fluoroquinolone therapy will always result in systemic drug levels. Evidence does not indicate that the use of two fluoroquinolones, such as ciprofloxacin and moxifloxacin, minimizes fluoroquinolone resistance. Resistance to quinolones has been a problem ever since nalidixic acid was introduced into clinical medicine 40 years ago. For a time, the greater potency of the fluoroquinolones, compared with that of older quinolones, permitted complacency regarding their use, but successful treatment outcomes led to increased use, which, in turn, led to an escalating rate of resistance.
