In a 0.125 mol/L phosphate (pH 6.6)/2.5 x 10(-4) mol/L 2-iodoacetamide solution, lomefloxacin yields a response of a polarographic catalytic current. The second-order derivative peak current of the catalytic wave of lomefloxacin is proportional to its concentration in the range of 1.0 x 10(-8)-1.0 x 10(-6) mol/L (r = 0.998). The sensitivity of the catalytic wave is 25-times higher than that of ...
The binding of lomefloxacin to bovine lactoferrin (BLf) in a dilute aqueous solution was studied using fluorescence spectra. The binding constant (K) and the number of binding sites (n) were obtained by a fluorescence quenching method. The binding distance (r) and energy-transfer efficiency (E) between lomefloxacin and bovine lactoferrin were also obtained according to the mechanism of Foörster...
The bacteriologic and clinical efficacies of 3 days of lomefloxacin therapy were compared with those of 3 days of norfloxacin therapy for the treatment of acute uncomplicated urinary tract infections in a prospective, randomized, double-blind study. One hundred sixty-four subjects were enrolled at five Canadian centers; 84 received lomefloxacin, and 80 received norfloxacin. Escherichia coli (84...
BACKGROUND Lomefloxacin is a potent bactericidal antibiotic. The use of this drug in treatment of various infections is accompanied by serious adverse effects on pigmented tissues. The exact mechanisms of lomefloxacin side effects have not been well established yet. The aim of this study was to characterize the interaction between lomefloxacin and melanin, and to examine how this interaction af...
The evaluation of eye and skin irritation potential is essential to ensuring the safety of human in contact with a wide variety of substances. Despite this importance of irritation test, little is known with respect to the irritation potency of lomefloxacin, a fluoroquinolone antibiotic, which has been known to cause phototoxicity with an abnormal reaction of the skin. Thus, to investigate the ...
Lomefloxacin is a broad-spectrum fluoroquinolone antibiotic used for the treatment of bacterial extraocular disease. This study investigated the efficacy and safety of lomefloxacin eye drops for bacterial extraocular disease in horses. Lomefloxacin ophthalmic solution (0.3%) was instilled three times daily for 2-5 days in 65 horses diagnosed with bacterial extraocular disease based on clinical ...
Oral doses of 400 mg of lomefloxacin were administered once daily prior to breakfast to 10 middle-aged to elderly hospitalized patients with chronic obstructive pulmonary disease during treatment for bronchopulmonary infections. Serial plasma and sputum samples and fractional urine samples were obtained over a steady-state dosing interval. Lomefloxacin concentrations were determined in duplicat...
An in vitro model simulating two-compartment pharmacokinetics was used to study the antibacterial activity of lomefloxacin after single oral doses of 200 and 400 mg. Lomefloxacin produced reliable bactericidal activity against gram-negative aerobic bacteria and staphylococci. Bacterial strains for which MICs were less than 0.5 microgram/ml were inhibited with both dosing schedules. Doubling the...
Fluoroquinolones (FQs) are extensively used in bacterial keratitis and other intraocular infections. Since eye is constantly exposed to light, incidence of ocular phototoxicity due to commonly used FQs is of great interest for their safe use. Phototoxicity of commonly used FQs (ciprofloxacin, lomefloxacin, pefloxacin, ofloxacin, sparfloxacin and gatifloxacin), has been evaluated by using HET-CA...
Single-dose plasma pharmacokinetics of theophylline (6 mg/kg intravenously) and renal excretion of theophylline and its metabolites, resulting from 8-oxidation and N-demethylation, were investigated in eight healthy volunteers before and at day 3 of concomitant oral administration of the quinolone derivative lomefloxacin (400 mg twice daily). Plasma samples were collected until 24.5 h, and urin...
