    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.

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. 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.

    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).

    The European Medicines Agency’s EMA Pharmacovigilance Risk Assessment Committee has recommended restricting the use of fluoroquinolone and quinolone antibiotics used by mouth, injection or inhalation following a review of disabling and potentially long-lasting side effects reported with these review incorporated the views of patients, healthcare professionals and academics. For this analysis we included three different strains of P. falciparum in order to assess for cross-resistance to existing antimalarials. D6 is sensitive to the action of chloroquine and moderately resistant to mefloquine while Dd2 is resistant to multiple drugs including chloroquine, mefloquine, quinine, pyrimethamine and sulfadoxine. Thus, fluoroquinolone use is typically reserved for cases in which the benefits clearly outweigh the risks. The spectrum of activity, mechanisms of action and resistance, important resistance patterns, and adverse effects of commonly available fluoroquinolones ie, ciprofloxacin, levofloxacin, moxifloxacin, delafloxacin will be reviewed here.
