Gatifloxacin is a recently developed antibacterial agent differing from earlier fluoroquinolones by the presence of a methoxy group at the C-8 position. The presence of the methoxy group has conferred improved antibacterial activity against both Gram-positive and Gram-negative organisms, making gatifloxacin a broad-spectrum antimicrobial agent applicable in many clinical settings. Gatifloxacin is sold under the brand Zymar and is indicated for the treatment of bacterial conjunctivitis caused by susceptible strains of the following organisms: Aerobic Gram-Positive Bacteria: Cornyebacterium propinquum, Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus mitis, Streptococcus pneumoniae and Aerobic Gram-Negative Bacteria: Haemophilus influenza. The antibacterial 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. In addition, Gatifloxacin inhibits bacterial topoisomerase IV. This enzyme is an enzyme known to play a key role in the partitioning of the chromosomal DNA during bacterial cell division. The mechanism of action of fluoroquinolones including gatifloxacin is different from that of aminoglycoside, macrolide, and tetracycline antibiotics. Therefore, gatifloxacin may be active against pathogens that are resistant to these antibiotics and these antibiotics may be active against pathogens that are resistant to gatifloxacin. There is no cross-resistance between gatifloxacin and the aforementioned classes of antibiotics. Cross-resistance has been observed between systemic gatifloxacin and some other fluoroquinolones.

Gatifloxacin was synergic with the beta-lactams piperacillin, cefepime and meropenem, and with gentamicin against some drug-resistant pathogens. It was investigated in vitro interaction of gatifloxacin in combination with these drugs against clinical isolates of Stenotrophomonas maltophilia, Pseudomonas aeruginosa, Burkholderia cepacia, extended-spectrum beta-lactamase (ESBL)-producing Klebsiella pneumoniae, vancomycin-resistant Enterococcus faecium (VRE) and methicillin-resistant Staphylococcus aureus (MRSA). Synergy was demonstrated with the following combinations at achievable serum concentrations: gatifloxacin/piperacillin for 80% and gatifloxacin/cefepime for 60% of S. maltophilia; gatifloxacin/gentamicin for 60%, and gatifloxacin/cefepime for 50% of ESBL-producing K. pneumoniae, and in all drug combinations for 50-70% of P. aeruginosa. Indifference was noted for the majority of B. cepacia and VRE isolates. Antagonism at therapeutic serum levels was observed with gatifloxacin/piperacillin against a single isolate of B. Cepacia. MIC50 and MIC90 values represent the concentrations at which 50% and 90% of strains, respectively, were inhibited. The gatifloxacin MICs for S. maltophilia ranged from 0.5 to 4 mg/L, the lowest values of the agents tested. Gatifloxacin at 2 mg/L in combination with cefepime at 8 mg/L, and gatifloxacin at 2 mg/L in combination with piperacillin at 64 mg/L, resulted in at least a 2 log10 decrease in viable colonies, and by definition were synergic.
