Resistance to levofloxacin develops as a result of a phased process of mutations of genes encoding both topoisomerases of type II: DNA-gyrase and topoisomerase IV.
Other resistance mechanisms, such as the mechanism of influence on the penetration barriers of the microbial cell (the mechanism characteristic of Pseudomonas aeruginosa) and the mechanism of efflux (active excretion of the antimicrobial from the microbial cell), can also reduce the sensitivity of microorganisms to levofloxacin.
Due to the peculiarities of the mechanism of action of levofloxacin, there is usually no cross-resistance between levofloxacin and other antimicrobial agents.



After oral administration, levofloxacin is rapidly and almost completely absorbed from the small intestine.
Food intake has little effect on the speed and completeness of absorption. Bioavailability of levofloxacin in a dose of 500 mg after oral administration is almost 100%. After taking a single dose of 500 mg C max levofloxacin is 5.2 В± 1.2 Ојg / ml,
Time to reach C max - 1.3 h.


Binding to plasma proteins - 30-40%.
Well penetrates into organs and tissues: lungs, bronchial mucosa, organs
genitourinary system, bone tissue, cerebrospinal fluid, prostate gland, polymorphonuclear leukocytes and alveolar macrophages.

Metabolism and excretion

In the liver, a small portion is oxidized and / or deacetylated.

It is excreted from the body mainly by the kidneys through glomerular filtration and tubular secretion.
T 1/2 - 6-8 hours. After oral administration, approximately 87% of the dose is excreted for 48 hours by the kidneys in unchanged form, less than 4% within 72 hours through the intestine.
Pharmacokinetics in specific patient groups

In renal failure, the decrease in clearance of levofloxacin and its excretion by the kidneys depends on the degree of decrease in the clearance of creatinine (CC).
With KK 50-80 ml / min T 1/2 is 9 hours, the renal clearance is 57 ml / min; with KK 20-49 ml / min T 1/2 is 27 hours, the renal clearance is 26 ml / min; when the SC is less than 20 ml / min T 1/2 is 35 hours, the renal clearance is 13 ml / min.

to the elderly. In the treatment of elderly patients, it should be borne in mind that they often suffer from impaired renal function.

The prevalence of acquired resistance of microorganisms can vary depending on the geographical region and over time, and therefore it is necessary to determine the sensitivity of the pathogen to levofloxacin.

There is a high probability that Staphylococcus aureus (methicillin-resistant strains) will be resistant to fluoroquinolones, including levofloxacin.
Therefore, levofloxacin is not recommended for treatment of established
or suspected of infections caused by Staphylococcus aureus (methicillin-resistant strains) if the laboratory tests did not confirm the sensitivity of the microorganism to levofloxacin.
Tendonitis rarely observed in the application of quinolones, including levofloxacin, may lead to rupture of the tendon, including the Achilles tendon. This side effect may occur within 48 hours after the start of treatment and may be bilateral. Elderly patients are more likely to develop tendinitis. Risk of tendon can be increased while taking corticosteroids. If tendinitis is suspected, immediately discontinue drug treatment and start appropriate therapy of the affected tendon, for example, to provide him with adequate immobilization.
Levofloxacin can cause serious, potentially fatal hypersensitivity reactions (angioneurotic edema, anaphylactic shock), even after the first dose. In the case of development, patients should stop taking the drug and seek emergency medical attention.
When receiving levofloxacin bullous observed cases of severe skin reactions such as Stevens-Johnson syndrome or toxic epidermal necrolysis. In the case of any reaction on the part of the skin or mucous membranes of the patient should seek medical advice immediately and not continue to treat his advice.
It reported cases of liver necrosis, including the development of fatal liver failure when using levofloxacin, mainly in patients with serious underlying diseases, such as sepsis. Patients should be warned about the need to stop treatment and urgent referral to a physician in case of signs and symptoms of liver damage, such as anorexia, jaundice, dark urine, itching, and abdominal pain.
Levofloxacin is excreted primarily through the kidneys, in patients with impaired renal function requires mandatory monitoring of renal function, as well as the correction of dosing regimen. In the treatment of elderly patients should be aware that patients in this group are often marked renal dysfunction.
As with other antibiotics, the use of levofloxacin, particularly during a long time may lead to an increased reproduction insensitive thereto microorganisms (bacteria and fungi), which may cause changes in the microflora, which is normally present in humans. As a result, may develop superinfection. Therefore, in the course of treatment required to reassess the patient's condition and in the case of superinfection during treatment should take appropriate measures.
It reported very rarely QT prolongation in patients receiving fluoroquinolones, including levofloxacin.
In applying fluoroquinolones, including levofloxacin, caution in patients with known
risk factors for QT interval elongation: Patients with uncorrected electrolyte disturbances (with hypokalemia, hypomagnesemia); congenital long QT interval syndrome; heart disease (heart
failure, myocardial infarction, bradycardia); while taking drugs capable of lengthening QT interval, such as antiarrhythmics of Class IA and III, tricyclic antidepressants, macrolides, antipsychotics. Elderly patients and female patients may be more sensitive to the drug, prolongs the QT interval. It should therefore be used with caution in these fluoroquinolones, including levofloxacin.
Despite the fact that the photosensitivity during treatment with levofloxacin observed infrequently, it is recommended to patients not exposed to strong sunlight or artificial UV radiation during treatment and for 48 hours after treatment.
Evolved during or after treatment with levofloxacin diarrhea, particularly severe, persistent and / or blood, can be a symptom of pseudomembranous colitis caused by Clostridium difficile. If you suspect a pseudomembranous
colitis should be lifted immediately levofloxacin and begin appropriate treatment (vancomycin, teicoplanin or
metronidazole inside). Contraindicated the use of drugs that suppress peristalsis.
As with other quinolones, levofloxacin should be used with caution in patients with a predisposition to the development of seizures: patients with previous CNS lesions (stroke, severe head injury), patients concurrently treated with drugs that reduce the seizure threshold of the brain activity, such as fenbufen and other NSAIDs or other drugs, such as theophylline. In the event of seizures of the drug should be discontinued.
Patients with a deficiency of glucose-6-phosphate dehydrogenase (an inherited metabolic disorder) can respond to fluoroquinolones destruction of erythrocytes (hemolysis). In connection with this, treatment with levofloxacin should be performed with caution.
As with other quinolones, when using levofloxacin observed cases of hyperglycemia and hypoglycemia, usually in diabetic patients receiving concomitant treatment with oral hypoglycemic agents (e.g. glibenclamide) or insulin preparations. Reported cases of hypoglycemic coma. In patients with diabetes require blood glucose concentration monitoring.
In patients receiving fluoroquinolones, including levofloxacin, marked sensory and sensory-motor peripheral neuropathy, the beginning of which can be rapid. If the patient has symptoms of neuropathy, the use of levofloxacin should be discontinued. This minimizes the possible risk of irreversible changes.
In the application of quinolones, including levofloxacin, it reported on the development of psychotic reactions, which in rare cases progressed to the development of suicidal thoughts and behavior disorders with self-harm (sometimes after a single dose of levofloxacin). With the development of these reactions should discontinue treatment levofloxacin and prescribe appropriate therapy. Caution should be prescribed to patients with psychosis or patients with a history of psychiatric illness.
With the development of any impairment need immediate consultation of the ophthalmologist.
With simultaneous use of anticoagulants and levofloxacin requires regular monitoring of blood coagulation parameters.
In patients treated with levofloxacin, determination of opiates in urine may lead to false-positive results, which should be confirmed by a more specific methods.
Levofloxacin can inhibit the growth of Mycobacterium tuberculosis and subsequently lead to false negative results bacteriological diagnosis of tuberculosis.
Fluoroquinolones, including levofloxacin, characterized by blocking neuromuscular activity holding and may enhance muscle weakness in patients with gravis.Observed adverse reactions, including pulmonary failure, requesting a ventilator, and death that was associated with the use of fluoroquinolones in patients with gravis. The use of levofloxacin in patients with an established diagnosis of gravis is not recommended.
Impact on the ability to drive vehicles and manage mechanisms

During the treatment should refrain from driving and classes of potentially hazardous activities that require high concentration and psychomotor speed reactions.

Symptoms of an overdose of the drug levofloxacin are shown on the central nervous system level (confusion, dizziness, impairment of consciousness, and seizures). In addition, it can be marked gastrointestinal symptoms (eg, nausea, vomiting) and erosive lesions of the mucous membranes of the gastrointestinal tract. In studies using ultrahigh doses of levofloxacin were shown lengthening the interval QT.
Treatment: gastric lavage and symptomatic therapy. Levofloxacin is output by hemodialysis or peritoneal dialysis.
There is no specific antidote.

There are reports of marked decrease in the seizure threshold, while the use of quinolones and substances that reduce the cerebral seizure threshold. This also applies to the simultaneous reception of quinolones and theophylline, as well as NSAIDs - propionic acid derivatives.
Pharmacokinetic interactions of levofloxacin with theophylline is not revealed.
Oral administration together with preparations containing divalent and trivalent cations such as zinc or iron salts (drugs for the treatment of anemia) of magnesium and / or aluminum-containing preparations (such as antacids), didanosine (only formulations containing as buffer aluminum or magnesium), resulting in decreased absorption and levofloxacin weakening effect, so it should be given 2 hours before or 2 hours after administration of the above drugs.
Calcium salts have a minimal effect on the absorption of levofloxacin when taken orally.
Action levofloxacin significantly attenuated while the use of sucralfate (the means to protect the gastric mucosa). Patients receiving levofloxacin and sucralfate, sucralfate advised to take 2 hours after receiving levofloxacin.
Levofloxacin concentration while taking fenbufen increased by only 13%.
With simultaneous use of vitamin K antagonists requires monitoring of blood coagulation parameters.
Patients treated with levofloxacin in combination with indirect anticoagulants (eg, warfarin), there was an increase in prothrombin time / INR and / or the development of bleeding, including heavy.
Therefore, while the use of anticoagulants and levofloxacin requires regular monitoring of blood coagulation parameters.
With simultaneous use of drugs that violate renal tubular secretion, such as probenecid and cimetidine, and levofloxacin, caution, especially in patients with renal insufficiency. Excretion (renal clearance) of levofloxacin slows down under the action of cimetidine on probenecid and 24% - 34%. It is unlikely that this could be of clinical importance in the normal renal function.
Levofloxacin while the use of antiarrhythmic drugs IA and Class III, tricyclic antidepressants, macrolides, antipsychotics may cause lengthening of the interval QT. Levofloxacin increases T 1/2 33% of cyclosporin.
Because this increase is clinically insignificant, cyclosporin dose correction at its simultaneous application of levofloxacin is required.
GCS increases the risk of tendon rupture.
Levofloxacin pharmacokinetics while the use of digoxin, glibenclamide, ranitidine, warfarin does not change sufficiently that it had clinical significance.
