The quinolones are synthetic antibiotics chemically related to nalidixic acid. Since its introduction, several structural analogues have been synthesized. A fundamental breakthrough was the addition of a fluorine atom. The quinolones interfere with bacterial DNA transcription by inhibiting the enzyme DNA gyrase, that so far has only been found in ...

The fluoroquinolones are a new class of antimicrobial agents structurally related to nalidixic acid. They have a broad spectrum of activity against pathogens, including Pseudomonas aeruginosa, other multiresistant gram-negative bacteria, and methicillin-resistant Staphylococcus aureus but not anaerobes. They are well absorbed after oral administration,

International Journal of Antimicrobial Agents, 1992
Fluoroquinolones have broad antibacterial spectra and are active against most Gram-negative and many Gram-positive species. They exhibit excellent oral bioavailability, extensive tissue penetration, low protein binding, and a long elimination half-life.

Quinolone pharmacokinetics in the elderly
The American Journal of Medicine, 1992As a class, quinolones undergo both renal excretion and hepatic metabolism. The dominant elimination pathway is usually renal, where secretion by the proximal tubule results in renal clearances 1.5-4 times greater than creatinine clearance. The benefit of this two-pathway elimination is protection from excessive accumulation in patients with single ...

Fluorinated quinolones — new quinolone antimicrobials
1992Paul Ehrlich started his research, called experimental chemotherapy, in 1902, and discovered Trypanrot in 1904 and Salvarsan in 1909. This was the first success of chemotherapy using man-made chemotherapeutic agents against microorganisms. Since the original observation by Fleming in 1929 of the effect of Penicillium notatum on a culture plate in his ...

Clinical Pharmacokinetics, 1992
The fluoroquinolones represent a relatively new class of antibiotics with outstanding therapeutic potential, attributable to their broad spectrum of antimicrobial activity and favourable tissue distribution. They are highly active against most Gram-negative pathogens, as well as Staphylococcus aureus and coagulase-negative staphylococci.

Use of the Quinolones in Paediatrics
Drugs, 1993For many years, quinolone-induced cartilage toxicity observed in experiments involving immature animals has represented an indisputable contraindication for the use of these promising antimicrobials in prepubertal patients. Clinical, magnetic resonance imaging and histopathological monitoring of patients receiving ciprofloxacin at the University of ...

Mechanisms of quinolone phototoxicity
Toxicology Letters, 1998We examined the mechanisms of quinolone phototoxicity in vivo and in vitro. Simultaneous p.o. administration of a quinolone and ultraviolet-A (UVA) irradiation for 4 h induced auricular skin inflammation in BALB/c mice, including edema and neutrophil infiltration in the dermis.
