Fluoroquinolone, a broad-spectrum antimicrobial bactericide.
It blocks DNA-gyrase (topoisomerase II) and topoisomerase IV, disrupts supercoiling and cross-linking of DNA gaps, inhibits DNA synthesis, causes profound morphological changes in the cytoplasm, cell wall and bacterial membranes.

After IV infusion, 500 mg for 60 min C max is about 6 Ојg / ml.
With iv in a single and repeated administration, the apparent V d after administration of the same dose is 89-112 liters.
The connection with plasma proteins is 30-40%.
It penetrates well into organs and tissues: lungs, bronchial mucosa, sputum, organs of the genitourinary system, polymorphonuclear leukocytes, alveolar macrophages.
In the liver, a small portion is oxidized and / or deacetylated.

Kidney clearance is 70% of the total clearance.
T 1/2 - 6-8 hours. Excreted mainly by the kidneys through glomerular filtration and tubular secretion. Less than 5% of levofloxacin is excreted as metabolites. In unchanged form, 70% are excreted by the kidneys within 24 hours and 87% in 48 hours.

Infectious-inflammatory diseases caused by susceptible to levofloxacin microorganisms:

- infections of the lower respiratory tract (exacerbation of chronic bronchitis, community-acquired pneumonia);

acute acute maxillary sinusitis;

uncomplicated urinary tract infections;

- Complicated urinary tract infections (including acute pyelonephritis);

- skin and soft tissue infections (festering atheromas, abscess, boils);

- septicemia / bacteremia;

- chronic bacterial prostatitis;

- intra-abdominal infection;

- complex therapy of drug-resistant forms of tuberculosis.


Solution for infusion is injected / drip.
The duration of IV infusion of 500 mg of levofloxacin (100 ml of infusion solution) should be at least 60 minutes. Doses are determined by the nature and severity of the infection, as well as the suspected pathogen susceptibility.
Patients with normal renal function (creatinine clearance> 50 ml / min) are recommended the following dosing regimen:

Exacerbation of chronic bronchitis: 250-500 mg of levofloxacin 1 time per day for 7-10 days;

Community-acquired pneumonia: 500 mg of levofloxacin 1-2 times a day for 7-14 days;

Acute maxillary sinusitis: 500 mg of levofloxacin 1 time per day for 10-14 days;

Uncomplicated urinary tract infections: 250 mg levofloxacin 1 time per day for 3 days;

Complicated urinary tract infections (including acute pyelonephritis): 250 mg of levofloxacin 1 time per day for 7-10 days;

Infections of the skin and soft tissues: 500 mg of levofloxacin 2 times a day for 7-14 days;

Septicemia / bacteremia: 500 mg of levofloxacin 1-2 times a day for 10-14 days;

Chronic bacterial prostatitis: 500 mg of levofloxacin 1 time per day for 28 days;

Intra-abdominal infection: 500 mg levofloxacin 1 time per day for 7-14 days (in combination with antibacterial drugs acting on anaerobic flora);

Complex therapy of drug-resistant forms of tuberculosis: 500 mg of levofloxacin 1-2 times a day for up to 3 months.

Patients with impaired renal function (creatinine clearance <50 mL / min) are recommended the following dosing regimen:

Creatinine clearance ml / min Dose for intravenous administration

250 mg / 24 h 500 mg / 12h 500 mg / 24 h

Initial dose 250 mg Initial dose 500 mg Initial dose 500 mg

50-20 Further 125 mg / 24 hours Further 250 mg / 24 hours Further 250 mg / 12 h

19-10 Further 125 mg / 48 h Further 125 mg / 24 h Further 125 mg / 12 h

<10 (including hemodialysis and permanent ambulatory peritoneal dialysis) Further 125 mg / 48 h Further 125 mg / 24 h Further 125 mg / 24 h

After hemodialysis or permanent ambulatory peritoneal dialysis (CAPD), no additional doses are required.

If there is a violation of the liver, dosage adjustment is not required, since levofloxacin is metabolized to a small extent in the liver.

Depending on the patient's condition after a few days of treatment, you can go from / in the drip to receive the same dose of the drug in a form intended for oral administration.

On the part of metabolism: hypoglycemia (increased appetite, increased sweating, trembling, nervousness), hyperglycemia.

From the side of the nervous system: headache, dizziness, weakness, drowsiness, insomnia, anxiety, paresthesia, fear, hallucinations, confusion, depression, movement disorders, convulsions.

From the senses: visual, hearing, smell, taste and tactile sensitivity.

From the musculoskeletal system: arthralgia, muscle weakness, myalgia, tendon rupture, tendonitis, rhabdomyolysis.

From the urinary system: hypercreatininaemia, interstitial nephritis, acute renal failure.

On the part of the organs of hematopoiesis: eosinophilia, hemolytic anemia, leukopenia, neutropenia, agranulocytosis, thrombocytopenia, pancytopenia, hemorrhages.

Hypersensitivity to levofloxacin, any other component of the drug or other drugs from the group of fluoroquinolones, epilepsy, tendon lesions with previously treated quinolones, pregnancy, lactation, children and adolescence (up to 18 years).

With caution: in the elderly due to the high likelihood of concomitant decline in kidney function, with a deficiency of glucose-6-phosphate dehydrogenase.


Contraindicated: pregnancy, lactation.


Patients with impaired renal function (creatinine clearance <50 mL / min) are recommended dose adjustment.


If there is a violation of the liver, dosage adjustment is not required, since levofloxacin is metabolized to a small extent in the liver.


Contraindicated: children and adolescence (up to 18 years).


With caution: in the elderly due to the high likelihood of concomitant decline in kidney function.


After normalization of body temperature, it is recommended to continue treatment for at least 48-72 hours. During treatment, sun and artificial UV irradiation should be avoided to avoid damage to the skin (photosensitivity).

When there are signs of tendinitis, pseudomembranous colitis, allergic reactions, levofloxacin is immediately canceled.

It should be borne in mind that the development of seizures is possible in patients with a history of brain damage (stroke, severe trauma), and the risk of hemolysis is a deficiency in glucose-6-phosphate dehydrogenase.

Influence on ability to operate mechanisms and the car.
During the treatment period, care must be taken when driving vehicles and engaging in other potentially hazardous activities that require increased concentration and speed of psychomotor reactions.

Symptoms: manifested primarily from the central nervous system (confusion, dizziness, impaired consciousness and seizures as epileptic seizures).
In addition, gastrointestinal disorders (eg, nausea) and erosive lesions of the mucous membranes of the gastrointestinal tract, prolongation of the QT interval can be noted.
Treatment: symptomatic.
Dialysis is ineffective. The specific antidote is not known.

Levofloxacin increases T 1/2 cyclosporin.

Non-steroidal anti-inflammatory drugs, theophylline increase the risk of seizures.

The use of glucocorticosteroids increases the risk of rupture of tendons.

Cimetidine and drugs that block tubular secretion, slow the withdrawal of levofloxacin.

Solution for infusion is compatible with 0.9% sodium chloride solution, 5% dextrose solution, 2.5% Ringer's solution with dextrose, combined solutions for parenteral nutrition (amino acids, carbohydrates, electrolytes).

Do not mix with heparin and solutions that have an alkaline reaction (for example, with sodium bicarbonate solution).

In patients with diabetes mellitus receiving oral hypoglycemic agents or insulin, against the background of the use of levofloxacin hypo- and hyperglycemic conditions are possible, therefore it is recommended to control the concentration of glucose in the blood.
Levofloxacin increases the anticoagulant activity of warfarin.
