Pharmacological properties
Pharmacodynamics
Levofloxacin is a synthetic broad-spectrum antibacterial drug that belongs to the group of fluoroquinolones. The active substance is the levorotatory isomer of ofloxacin. The drug inhibits the synthesis of deoxyribonucleic acid (DNA), disrupts supercoiling and stitching of DNA breaks, inhibits topoisomerase IV and DNA gyrase, promotes the development of deep morphological changes in the membranes, cytoplasm and cell wall of bacteria. Shows activity against most strains of microorganisms in vitro and in vivo.
In vitro sensitivity to Levofloxacin-VERTEX is shown by the following microorganisms [in the zone of inhibition ≥ 17 mm, minimum inhibitory concentration (MIC) ≤ 2 mg / L]:
- Gram-negative aerobes: Acinetobacter spp., Citrobacter freundii, Acinetobacter baumannii, Aggregatibacter (formerly Actinobacillus) actinomycetemcomitans, Enterobacter aerogenes, Eikenella corrodens, Escherichia coli, Enterobacter Rugilis spp., Enterobacter vaginus cloacae, Enterobacter influenza cloacae ampicillin-susceptible / -resistant), Klebsiella oxytoca, Klebsiella spp., Helicobacter pylori, Klebsiella pneumoniae, Haemophilus parainfluenzae, Moraxella catarrhalis β + / β- (producing and non-producing PPr-lactamase non-beta-lactamase), Morganella Nephi producing and non-producing penicillinase), Pasteurella dagmatis, Pasteurella canis, Neisseria meningitidis, Pasteurella spp., Pasteurella multocida, Proteus vulgaris, Proteus mirabilis, Providencia spp., Providencia stuartii,Providencia rettgeri, Pseudomonas aeruginosa, Pseudomonas spp., Serratia marcescens, Salmonella spp., Serratia spp.;
- aerobes gram-positive: Corynebacterium jeikeium, Bacillus anthracis, Enterococcus faecalis, Listeria monocytogenes, Corynebacterium diphtheriae, Enterococcus spp., Staphylococcus coagulase-negative methi-S (I) (moderately sensitive, methi-S (I) (coagulasesensitive / sensitive) Staphylococcus aureus methi-S (methicillin-sensitive), Staphylococcus spp. CNS (coagulase negative), Streptococcus agalactiae; Streptococci groups C and G, Streptococcus pneumoniae peni I / S / R (penicillin-moderately sensitive / -sensitive / -resistant), Viridans streptococci peni-S / R penicillin-sensitive / -resistant);
- anaerobes: Bifidobacterium spp., Bacteroides fragilis, Clostridium perfringens, Veillonella spp., Propionibacterium spp., Peptostreptococcus, Fusobacterium spp.;
- other microorganisms: Chlamydia psittaci, Chlamydia pneumoniae, Bartonella spp., Chlamydia trachomatis, Legionella spp., Legionella pneumophila, Mycobacterium tuberculosis, Mycobacterium spp., Mycoplasma hominalyumis.
The following microbes exhibit moderate sensitivity to Levofloxacin-VERTEX (inhibition zone 16–14 mm, MIC = 4 mg / l):
- gram-negative aerobes: Campylobacter coli, Campylobacter jejuni;
- gram-positive aerobes: Enterococcus faecium, Corynebacterium xerosis, Corynebacterium urealyticum; Staphylococcus haemolyticus methi-R and Staphylococcus epidermidis methi-R (methicillin-resistant);
- anaerobes: Porphyromonas spp., Prevotella spp.
In vitro resistance to Levofloxacin-VERTEX is shown by the following microorganisms (zone of inhibition ≤ 13, MIC ≥ 8 mg / l):
- gram-negative aerobes: Alcaligenes xylosoxidans;
- gram-positive aerobes: Staphylococcus coagulase-negative methi-R (coagulase-negative methicillin-resistant), Staphylococcus aureus methi-R (methicillin-resistant);
- anaerobes: Bacteroides thetaiotaomicron;
- other microorganisms: Mycobacterium avium.
Resistance in strains of infectious pathogens to the action of levofloxacin arises as a result of the stepwise process of the formation of mutations in genes that encode both type II topoisomerases - DNA gyrase and topoisomerase IV. Also, mechanisms such as the effect on the penetration fences of the microbial cell (characteristic of Pseudomonas aeruginosa) and efflux (active excretion of the antibacterial agent from the microbe cell) can also contribute to the increase in the resistance of microorganisms to Levofloxacin-VERTEX.
As a rule, cross-resistance between levofloxacin and other antimicrobial drugs is not observed, which is explained by the mechanism of action of this active substance.
In the course of clinical studies, the efficacy of Levofloxacin-VERTEX in the treatment of infectious lesions excited by the following microorganisms was established:
- gram-negative aerobes: Haemophilus influenzae, Citrobacter freundii, Escherichia coli, Haemophilus parainfluenzae, Enterobacter cloacae, Klebsiella pneumoniae, Morganella morganii, Moraxella (Branhamella) catarrhalis, Pseudomonas aerugilis, Proteces marns;
- gram-positive aerobes: Staphylococcus aureus, Enterococcus faecalis, Streptococcus pyogenes, Streptococcus pneumoniae;
- other microorganisms: Legionella pneumophila, Chlamydia pneumoniae, Mycoplasma pneumoniae.
Pharmacokinetics
After oral administration of Levofloxacin-VERTEX, the active substance is rapidly and almost completely absorbed. Food intake has little effect on its absorption. Absolute bioavailability is 99-100%. The maximum concentration (C max) of levofloxacin in the blood plasma after taking it at a dose of 500 mg is fixed after 1-2 hours and is 5.2 ± 1.2 μg / ml. After taking doses in the range of 50-1000 mg, the pharmacokinetics of the antimicrobial agent is linear. The equilibrium state of the plasma content of levofloxacin when taken orally at a dose of 500 mg 1-2 times / day is achieved within 48 hours.
On the 10th day of treatment with levofloxacin at a dose of 500 mg 1 time / day, its C max was 5.7 ± 1.4 μg / ml, and the minimum plasma concentration (C min), the level before the next dose, was 0.5 ± 0, 2 μg / ml. On the 10th day of taking 500 mg 2 times / day, C max was 7.8 ± 1.1 μg / ml, C min - 3.0 ± 0.9 μg / ml.
The agent binds to serum proteins by 30-40%. With single and repeated use at a dose of 500 mg, the volume of distribution (V d) of the active substance is on average 100 liters, which indicates a wide distribution in organs and tissues.
After oral administration 1 time / day at a dose of 500 mg in the fluid of the epithelial lining and bronchial mucosa, C max of levofloxacin was observed for 4 or 1 h, respectively, and amounted to 10.8 μg / ml and 8.3 μg / g, with penetration coefficients in epithelial lining fluid and bronchial mucosa compared with plasma levels in the blood - 0.8-3 and 1.1-1.8, respectively. On the sixth day of treatment at the same dose, 4 hours after the last use of Levofloxacin-VERTEX, its mean concentrations in alveolar macrophages and epithelial lining fluid were 97.9 and 9.94 μg / ml, respectively.
In lung tissue after oral administration of the active substance at a dose of 500 mg, C max was approximately 11.3 μg / g and was fixed after 4–6 hours, with penetration coefficients of 2–5 when compared with plasma levels.
In the alveolar fluid, 3 days after the start of administration, 1 or 2 times / day, 500 mg Cmax of levofloxacin was reached 2–4 hours after administration and amounted to 4 and 6.7 μg / ml, respectively, with a penetration coefficient of 1, compared to plasma level. In the tissue of the prostate gland after taking 1 time / day for 3 days, the content of the agent was 8.7 μg / g, the ratio of prostate / blood plasma concentrations was approximately 1.84.
8–12 hours after oral administration of levofloxacin at doses of 150, 300, or 600 mg, its mean urinary concentrations were 44, 91, or 162 μg / ml, respectively.
The drug does not penetrate well into the cerebrospinal fluid. It is well distributed in cancellous and cortical bone tissue, including the proximal and distal femur, with a penetration coefficient (bone tissue / blood plasma) of 0.1–3. In the cancellous bone tissue of the proximal femur, after taking 500 mg after 2 hours, the C max of levofloxacin averaged 15.1 μg / g.
The active substance is biotransformed very weakly, at the level of 5% of the dose received. In the process of metabolism of levofloxacin, N-oxide levofloxacin and desmethyl levofloxacin are formed, excreted by the kidneys. Due to stereochemical stability, the starting material is not subject to chiral transformations.
Levofloxacin is excreted slowly from plasma after oral administration, half-life (T 1/2) is 6–8 hours. More than 85% of the dose taken is eliminated in the urine, total clearance after administration of 500 mg is 175 ± 29.2 ml / min.
Oral administration and intravenous (IV) administration of levofloxacin are interchangeable, as indicated by the absence of significant differences in its pharmacokinetics after oral and parenteral use.
Pharmacokinetic parameters of levofloxacin do not differ in women and men.

Overdose
The main symptoms of an acute overdose of Levofloxacin-VERTEX may include the following reactions: impaired consciousness (including confusion), tremors, convulsions, hallucinations. It is also possible the appearance of nausea, erosive defects of the mucous membrane of the gastrointestinal tract (GIT), prolongation of the QT interval.
In this condition, the patient requires careful observation, including monitoring the electrocardiogram, conducting symptomatic therapy. Against the background of an acute overdose, gastric lavage and antacids are necessary in order to protect the gastric mucosa. Levofloxacin-VERTEX is not excreted from the body using peritoneal dialysis, hemodialysis, and continuous ambulatory peritoneal dialysis (CAPD). There is no specific antidote.
special instructions
It is not recommended to use Levofloxacin-VERTEX for the treatment of diagnosed / suspected infections caused by methicillin-resistant Staphylococcus aureus, since this pathogen is characterized by insensitivity to fluoroquinolones, including to levofloxacin.
Combination therapy may be necessary for the treatment of nosocomial infections with Pseudomonas aeruginosa (Pseudomonas aeruginosa).
When treating severe infections or insufficient effect of the course, confirmation of the diagnosis is required by the results of a microbiological test, including the identification of the pathogen and determination of the degree of its sensitivity to levofloxacin.
The use of fluoroquinolones (including levofloxacin) has been associated in some cases with disability and irreversible severe complications. While taking the drug, the development of such adverse events as arthralgia, myalgia, tendon rupture (including the Achilles tendon), tendinitis, peripheral neuropathy, reactions from the central nervous system (depression, hallucinations, confusion) can be observed. These side effects can manifest themselves in people of any age, both in the presence and absence of risk factors, after the first administration of Levofloxacin-VERTEX for a period from 2-3 hours to 14 days or more. If the initial symptoms of any adverse severe adverse reactions develop, the pill should be stopped immediately.
Since the use of an antimicrobial agent, especially during a long course of treatment, can cause increased reproduction of bacteria and fungi resistant to it, and thereby lead to a change in the normal composition of microflora and the subsequent development of superinfection, during therapy it is necessary to re-evaluate the patient's condition.
Fluoroquinolones, as a result of the activity inhibiting neuromuscular conduction, can aggravate muscle weakness against the background of pseudoparalytic myasthenia gravis. During the post-marketing period, such side effects as respiratory failure (requiring mechanical ventilation) and death associated with the use of fluoroquinolones in patients with pseudoparalytic myasthenia gravis were reported. If this diagnosis has been confirmed, therapy with Levofloxacin-VERTEX is contraindicated.
In patients receiving levofloxacin, false positive results may be obtained when determining opiates in urine. Also, similar results due to the suppression of the growth of Mycobacterium tuberculosis by the drug can be recorded during the subsequent bacteriological diagnosis of tuberculosis.
Influence on the ability to drive vehicles and complex mechanisms
Due to the possible development of drowsiness, dizziness / vertigo or visual impairment during the period of taking Levofloxacin-VERTEX, patients are advised to refrain from driving and servicing other complex moving machines and mechanisms.
Application during pregnancy and lactation
For pregnant and lactating women, therapy with Levofloxacin-VERTEX is contraindicated, since when using the drug during pregnancy and lactation, there is a threat of damage to the epiphyseal plate, which is responsible for the growth of bones in the fetus / child.
Pediatric use
The antimicrobial agent is not prescribed for children and adolescents due to incomplete growth of the skeleton, since in this age category, the risk of damage to the cartilaginous growth zones cannot be completely excluded against the background of taking Levofloxacin-VERTEX.
With impaired renal function
As the impairment of renal function aggravates, the renal clearance (CLR) decreases and the renal elimination of levofloxacin decreases, and its T 1/2 increases.
Pharmacokinetics of Levofloxacin-VERTEX in patients with renal insufficiency after a single oral dose of 500 mg (CC in ml / min):
- CC <20: CLR - 13 ml / min, T 1/2 - 35 h;
- CC - 20–49: CLR - 26 ml / min, T 1/2 - 27 h;
- CC - 50-80: CLR - 57 ml / min, T 1/2 - 9 hours.
Patients with nephrological pathology (CC ≤ 50) require mandatory monitoring of renal function and a change in the dosage regimen, set depending on the CC values and the recommended dose of Levofloxacin-VERTEX for patients with normal or moderately reduced renal function.
Recommended correction of the dosage regimen, at the required dose of 250 mg / 24 h, if CC> 50 (CC in ml / min):
- CC - 50–20: 1st dose - 250 mg, further - 125 mg / 24 h;
- CC - 19–10: 1st dose - 250 mg, further - 125 mg / 48 h;
- CC <10, including hemodialysis and CAPD *: 1st dose - 250 mg, further - 125 mg / 48 hours.
Recommended correction of the dosage regimen, at the required dose of 500 mg / 24 h, if CC> 50:
- CC - 50–20: 1st dose - 500 mg, further - 250 mg / 24 h;
- CC - 19-10: 1st dose - 500 mg, further - 125 mg / 24 h;
- CC <10, including hemodialysis and CAPD *: 1st dose - 250 mg, then 125 mg / 24 hours.
Recommended correction of the dosage regimen, at the required dose of 500 mg / 12 h, if CC> 50:
- CC - 50–20: 1st dose - 500 mg, further - 250 mg / 12 h;
- CC - 19–10: 1st dose - 500 mg, further - 125 mg / 12 h;
- CC <10, including hemodialysis and CAPD *: 1st dose - 500 mg, further - 125 mg / 24 h.
* After hemodialysis and CAPD, there is no need to take additional doses.
When prescribing the drug in a dose of 125 mg, Levofloxacin-VERTEX 250 mg tablets with a dividing line should be used.
For violations of liver function
Patients with functional disorders of the liver do not need individual dose selection, since in the liver the drug is metabolized to an insignificant extent.
Use in the elderly
In elderly patients, the pharmacokinetics of Levofloxacin-VERTEX does not differ from that in younger patients, except for differences associated with changes in CC. Elderly patients with CC> 50 ml / min do not need to change the dosage regimen.
Drug interactions
- sucralfate (an agent that protects the gastric mucosa): there is a pronounced decrease in the effect of levofloxacin; it is recommended to use sucralfate 2 hours after the administration of levofloxacin;
- calcium salts: there is a minimal effect of calcium salts on the absorption of levofloxacin;
- fenbufen, theophylline or similar medicinal substances from the group of non-steroidal anti-inflammatory drugs (NSAIDs), which help to reduce the seizure threshold of the brain: there is no pharmacokinetic interaction of levofloxacin with theophylline, but it has been established that quinolones can increase the ability of these NSAIDs to reduce the seizure threshold; when combined with fenbufen, the concentration of levofloxacin increases by 13%;
- agents containing bivalent / trivalent cations, including iron or zinc salts (drugs for the treatment of anemia), magnesium and / or aluminum-containing drugs (antacids); dosage forms of didanosine containing magnesium / aluminum as a buffer: it is recommended to take levofloxacin at least 2 hours before or after oral administration of these agents;
- GCS: the threat of tendon rupture is aggravated;
- cyclosporine: there is an increase in T 1/2 of this substance by 33%, but since this increase is clinically insignificant, no dose adjustment of cyclosporine is required;
- cimetidine, probenecid (substances that disrupt renal tubular secretion): there is a slowdown in the excretion of levofloxacin under the action of probenecid and cimetidine by 34 and 24%, respectively; with this combination, care must be taken, especially in patients with renal insufficiency;
- indirect anticoagulants (vitamin K antagonists), including warfarin: there is an increase in the international normalized ratio (INR) or prothrombin time, and / or the occurrence of bleeding, including severe; requires regular monitoring of blood clotting indicators;
- glibenclamide, digoxin, warfarin, ranitidine: do not show a clinically significant effect on the pharmacokinetics of levofloxacin;
- antihistamines (terfenadine, ebastine, astemizole), tricyclic and tetracyclic antidepressants, class IA and III antiarrhythmics, antipsychotics, macrolides, antifungals, imidazole derivatives (drugs that prolong the QT interval): Levofloxacin should be used with these agents with caution.
