OBJECTIVE To compare the efficacy and tolerability of a fixed combination of 0.3% gatifloxacin and 1% prednisolone(ZypredH) versus the individual components used separately (Zymar® and Predfort® ) for infection prophylaxis and inflammation control after cataract surgery with intraocular lens implantation [corrected]. METHODS A prospective, randomized, double-blind, parallel-group study of 108...
Limited evidence suggests that broad-spectrum fluoroquinolones such as gatifloxacin and moxifloxacin are more likely to cause Clostridium difficile-associated disease than levofloxacin. In a population-based case-control study of outpatients prescribed fluoroquinolones, we found no increased risk of C. difficile-associated disease requiring hospitalization among patients prescribed gatifloxacin...
Previous studies have demonstrated that fluoroquinolone area under the curve (AUC)/MIC ratios of 30 to 50 are sufficient to eradicate pneumococci from in vitro pharmacokinetic models (IVPMs). However, more systematic studies of the impact of AUC/MIC ratios on the antipneumococcal activities of fluoroquinolones are needed. In the present study, a two-compartment IVPM was used to evaluate the imp...
BACKGROUND Drug resistant typhoid fever is a major clinical problem globally. Many of the first line antibiotics, including the older generation fluoroquinolones, ciprofloxacin and ofloxacin, are failing. OBJECTIVES We performed a randomised controlled trial to compare the efficacy and safety of gatifloxacin (10 mg/kg/day) versus azithromycin (20 mg/kg/day) as a once daily oral dose for 7 day...
BACKGROUND We aimed to investigate whether gatifloxacin, a new generation and affordable fluoroquinolone, is better than chloramphenicol for the treatment of uncomplicated enteric fever in children and adults. METHODS We did an open-label randomised superiority trial at Patan Hospital, Kathmandu, Nepal, to investigate whether gatifloxacin is more effective than chloramphenicol for treating un...
CLINICAL PHARMACOLOGY Pharmacokinetics: Gatifloxacin ophthalmic solution 0.3% or 0.5% was administered to one eye of 6 healthy male subjects each in an escalated dosing regimen starting with a single 2-drop dose, then 2 drops 4 times daily for 7 days and finally 2 drops 8 times daily for 3 days. At all time points, serum gatifloxacin levels were below the lower limit of quantification (5 ng/mL)...
This study evaluated cross-resistance of Mycobacterium tuberculosis strains to ofloxacin, moxifloxacin, and gatifloxacin and investigated the presence of mutations in gyrA and gyrB. Fluoroquinolone susceptibilities were determined for 41 M. tuberculosis strains by the proportion method on 7H11, and MICs were determined by the resazurin microtiter assay. Forty strains shared the same resistance ...
In order to improve the frequent dosing regimen reported for the commercial aqueous gatifloxacin eye drops, two new ophthalmic mucoadhesive formulations based on high molecular weight sodium hyaluronate were prepared. The pharmacokinetic profiles outlined showed a strong bioavailability increase for gatifloxacin-hyaluronate formulations with respect to aqueous conventional eye drop. Gatifloxaci...
OBJECTIVES To compare the fluoroquinolones gatifloxacin and moxifloxacin with ciprofloxacin for post-exposure prophylaxis of systemic anthrax in a BALB/c mouse model. METHODS Treated mice and controls were inoculated subcutaneously with 5 x 10(4) spores/mouse of Bacillus anthracis Ames strain and observed for 37 days after challenge. Treated mice were given 100 mg/kg of antibiotic orally twic...
A single 400 mg oral dose of gatifloxacin was given to each of nine healthy male volunteers and the concentrations of the drug in plasma, cantharidine-induced inflammatory fluid and urine were measured over the following 24 h. The mean peak concentration in plasma of 4. 1 mg/L was attained at a mean time of 1.8 h post dose. The mean peak concentration in inflammatory fluid was 3.6 mg/L and was ...
