Levoflocin Pharmacological properties

The drug has a wide range of antimicrobial action. Rapid bactericidal effect is provided due to inhibition by levofloxacin of the bacterial enzyme DNA gyrase, which belongs to type II topoisomerases. As a result, the volumetric structure of the DNA of bacteria is disrupted and their division is blocked.

The spectrum of activity of levofloxacin includes the following microorganisms.

Gram-positive aerobes: Enterococcus faecalis, Staphylococcus aureus methi-S, Staphylococcus haemolyticus methi-S, Staphylococcus saprophyticus, Streptococci group C, G, Streptococcus agalactiae, Streptococcus pneumoniae penige Seni – S /.

Gram-negative aerobes: Acinetobacter baumannii, Citrobacter freundii, Eikenella corrodens, Enterobacter agglomerans, Enterobacter cloacae, Escherichia coli, Haemophilus influenzae ampi-S / R, Haemophilus para-influenzae, Klebsiella morxalalia, Klebsiella oxytola, Moria Pasteurella multocida, Proteus mirabilis, Proteus vulgaris, Providencia rettgeri, Providencia stuartii, Pseudomonas aeruginosa, Serratia marcescens.

Anaerobes: Bacteroides fragilis, Clostridium perfringens, Peptostreptococcus.

Others: Chlamydia pneumoniae, Chlamydia psittaci, Legionella pneumophila, Mycoplasma pneumoniae, Ureaplasma, H. pylori.

The following are constantly sensitive to the drug:

gram-positive aerobes: Stphylococcus haemolyticus methi-R;
gram-negative aerobes: Burkholderia cepacia;
anaerobes: Bacteroides ovatus, Bacteroides thetaiiotamicron, Bacteroides vulgaris, Clostridium difficile.
Resistant to the drug:

gram-positive aerobes: Staphylococcus aureus methi – R.
Like other fluoroquinolones, levofloxacin is inactive against spirochetes.

Species that may become resistant

Gram-positive aerobes: Enterococcus faecalis, Staphylococcus aureus methicillin-sensitive, coagulase-negative Staphylococcus spp.

Gram-negative aerobes: Acinetobacter baumannii, Citrobacter freundii, Enterobacter aerogenes, Enterobacter cloacae, Escherichia coli, Klebsiella pneumoniae, Morganella morganii, Proteus mirabilis, Providencia stuartii, Pseudomonas aerucescea, Serrati.

Anaerobes: Bacteroides fragilis.

Naturally resistant strains

Gram-positive aerobes: Enterococcus faecium.

Mechanism of resistance development

Resistance to levofloxacin develops as a stepwise mutation of the target site in both types of topoisomerase II, DNA gyrase and topoisomerase IV. Other mechanisms of resistance, such as permeability (characteristic of Pseudomonas aeruginosa), and outflow mechanisms may also affect sensitivity to levofloxacin.

There is cross-resistance between levofloxacin and other fluoroquinolones. Due to the mechanism of action, there is no cross-resistance between levofloxacin and other classes of antibacterial agents.
