Description
Lafrax Pharmacodynamics
A broad-spectrum antimicrobial of the group of fluoroquinolones, it acts on the bacterial enzyme DNA-gyrease, which provides superspiralization and thus stability of DNA bacteria (destabilization of DNA chains leads to their death). It has a bactericidal effect. It is active against beta-lactamase-producing microorganisms and fast-growing atypical mycobacteria. Sensitive: Staphylococcus aureus (including strains), Staphylococcus epidermidis, Streptococcus pneumoniae, Streptococcus pyogenes, Enterococcus faecalis, Corynebacterium spp, Micrococcus spp, Bacillus spp, Enterobacteriaceae (Escherichia coli, Citrobacter, Enterobacter spp, Klebsiela spp, Proteus spp., Salmonella spp., Serratia spp., Shigella spp.), Pseudomonas aeruginosa and Pseudomonas species, Haemophilus influenza, Haemophilus ducreyi, Branhamella catarhalis, Neisseria gonorrhoeae, Neisseria menengitidis, Acinetobacter spp, Campylobacter spp., Gardenerella vaginalis, Helicobacter pylori, Brucella spp. The drug also shows activity against Chlamydia trachomatis, Chlamydia pneumoniae, Mycoplasma pneumoniae and some other mycoplasmas.
Clostridium species, Bacteroides species and Peptococcus species are resistant. The resistance of Pseudomonas aeruginosa varies between 15-20% and the resistance of Staphylococcus aureus between 5-10%.

2 times a day for 14 days. - Children from 1 to 11 years of age
