Überblick

Gatifloxacin is a monocarboxylic acid that is 4-oxo-1,4-dihydroquinoline-3-carboxylic acid which is substituted on the nitrogen by a cyclopropyl group and at positions 6, 7, and 8 by fluoro, 3-methylpiperazin-1-yl, and methoxy groups, respectively. Gatifloxacin is an antibiotic of the fourth-generation fluoroquinolone family, that like other members of that family, inhibits the bacterial topoisomerase type-II enzymes. It has a role as an antimicrobial agent, an antiinfective agent and an EC 5.99.1.3 [DNA topoisomerase (ATP-hydrolysing)] inhibitor. It is a quinolone, a quinolinemonocarboxylic acid, an organofluorine compound, a N-arylpiperazine and a quinolone antibiotic.

Toxikologische Informationen

Treatment · 1 Eintrag

In the event of acute oral overdose, the stomach should be emptied by inducing vomiting or by gastric lavage. The patient should be carefully observed (including ECG monitoring) and given symptomatic and supportive treatment. Adequate hydration should be maintained. (L1712)

Health EffectsAntibiotic resistance
Exposure RoutesOphthalmic. Well absorbed from the gastrointestinal tract after oral administration with absolute bioavailability of gatifloxacin is 96%
Toxicity SummaryThe bactericidal action of Gatifloxacin results from inhibition of the enzymes topoisomerase II (DNA gyrase) and topoisomerase IV, which are required for bacterial DNA replication, transcription, repair, and recombination.
Signs and SymptomsThe most common side effects from antibiotics are diarrhea, nausea, vomiting. Fungal infections of the mouth, digestive tract and vagina can also occur with antibiotics
Carcinogen ClassificationNo indication of carcinogenicity to humans (not listed by IARC).

Pharmacodynamics · 1 Eintrag

Gatifloxacin is a synthetic broad-spectrum 8-methoxyfluoroquinolone antibacterial agent for oral or intravenous administration. is bactericidal and its mode of action depends on blocking of bacterial DNA replication by binding itself to an enzyme called DNA gyrase, which allows the untwisting required to replicate one DNA double helix into two. Notably the drug has 100 times higher affinity for bacterial DNA gyrase than for mammalian. Gatifloxacin is a broad-spectrum antibiotic that is active against both Gram-positive and Gram-negative bacteria. It should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria.

Mechanism of ActionThe bactericidal action of Gatifloxacin results from inhibition of the enzymes topoisomerase II (DNA gyrase) and topoisomerase IV, which are required for bacterial DNA replication, transcription, repair, and recombination.
