An antimicrobial agent of broad-spectrum, fluoroquinolone. Has a bactericidal effect. Levofloxacin does DNK-girazu (topoisomerase II) and topoisomerase IV, violates supercoiling and cross-linking of DNA breaks, inhibits DNA synthesis, causes profound morphological changes in cytoplasm, cell walls and membranes of bacterial cells.

Active against Acinetobacter anitratus, Acinetobacter baumannii, Acinetobacter calcoaceticus, Bordetella pertussis, Citrobacter diversus, Citrobacter freundii, Clostridium perfringens, Chlamydia pneumonia, Enterococcus faecalis, Enterobacter cloacae, Enterobacter aerogenes, Enterobacter agglomerans, Enterobacter sakazakii, Escherichia coli, Haemophilus influenzae, Haemophilus parainfluenzae, Klebsiella pneumoniae, Klebsiella oxytoca, Legionella pneumophila, Moraxella catarrhalis, Mycoplasma pneumoniae, Morganella morganii, Proteus mirabilis, Pseudomonas aeruginosa, Pseudomonas fluorescens, Proteus vulgaris, Providencia rettgeri, Providencia stuartii, Serratia marcescens, Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pneumoniae, Streptococcus pyogenes and Streptococcus agalactiae, Streptococcus spp. the viridians group.

Pharmacokinetics

After instillation into the eyes of levofloxacin is well maintained in the tear film. In studies in healthy volunteers have shown that the average concentration of levofloxacin in the tear film, measured after 4 and 6 h after topical application were 17 mcg/ml and 6.6 µg/ml, respectively. Five of the six volunteers the concentration of levofloxacin was 2 µg/ml and above after 4 h after instillation. In four of six volunteers this concentration remained after 6 h after instillation. The average concentration of levofloxacin in the application of eye drops in watery moisture is statistically significantly higher mean concentration of ofloxacin (p=0.0008). In fact it is approximately twice higher than average concentration of ofloxacin (1139.9±717.1 ng/ml, 621.7±368.7 ng/ml, respectively).

The average levofloxacin concentration in plasma 1 hour after application – 0.86 ng/ml at day 1 to 2.05 ng/ml Cmax of levofloxacin in plasma, equal to 2.25 ng/ml detected on day 4 after two days of the drug every 2 hours up to 8 times/day. Cmax of levofloxacin achieved on the 15th day, more than 1000 times lower than those concentrations which are observed after ingestion of standard doses of levofloxacin.
