PHARMACOKINETICS

When ingestion, levofloxacin is rapidly and almost completely absorbed (food intake has little effect on the speed and completeness of absorption).
Bioavailability is 99%. Т mах in plasma - 1-2 hours. At reception of 500 mg С max in a plasma makes 5,2 mkg / ml. The connection with plasma proteins is about 30-40%.
Moderate cumulation of levofloxacin is observed already on the third day of taking the drug at a dose of 500 mg 2 times a day.
It penetrates well into organs and tissues: lungs, bronchial mucosa, sputum, organs of the genitourinary system, polymorphonuclear leukocytes, alveolar macrophages. With max in the bronchial mucosa and the fluid of the epithelial lining after oral administration, 500 mg of the drug are 8.3 μg / g and 10.8 μg / ml, respectively; With MAX, levofloxacin in the blister fluid is 4.0-6.7 μg / ml, T max in this case is 2-4 hours. With max in the lung tissues after oral administration, 500 mg of the drug is 11.3 μg / g, and T max - 4-6 hours. Levofloxacin penetrates into the cerebrospinal fluid in small amounts. After oral administration of 500 mg / day of levofloxacin on the third day of treatment with Cmax in the tissues of the prostate at 2, 6 and 24 hours after the administration of the drug, 8.7 μg / g, 8.2 μg / g and 2.0 μg / g, respectively . The ratio of prostatic / plasma concentrations averaged 1.84. The average C max value in the urine after taking 500 mg of the drug after 8-12 hours is 200 mg / l. In the liver, a small part of the preparation is oxidized and / or deacetylated. T 1/2 - 6-8 hours. Excreted mainly by the kidneys (about 85% of the dose) by glomerular filtration and tubular secretion. 4% of the ingested dose of levofloxacin is excreted by the intestine within 72 hours. In cases of violations of kidney function and a decrease in renal clearance, T 1/2 is increased.
During clinical trials, there was no difference in the pharmacokinetics of the drug in men and women.

t, myasthenia gravis, psychosis and other psychiatric disorders in history, hepatic porphyria, simultaneous administration of drugs that extend the QT interval (antiarrhythmics of Class I and III, tricyclic and tetracyclic antidepressants, neuroleptics, macrolides, antifungal - imidazole derivatives, some antihistamines, in including astemizole, terfenadine, ebastin) and lowering the threshold of convulsive brain readiness (fenbufen, theophylline).
PREGNANCY AND LACTATION

Contraindicated in pregnancy and lactation (breastfeeding).

APPLICATION FOR FUNCTIONS OF THE LIVER

With caution: kidney failure.

APPLICATION FOR CHILDREN

Contraindicated in childhood and adolescence (under 18 years).

APPLICATION IN ELDERLY PATIENTS

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

SPECIAL INSTRUCTIONS

OD-Levox should be used at least 2 hours before or 2 hours after taking iron, zinc, antacid and sucralfate salts.

During treatment with OD-Levox, 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, OD-Levox immediately abolished.

It should be noted that in patients with a history of brain damage (stroke, severe trauma), convulsions may develop, with insufficiency of glucose-6-phosphate dehydrogenase - the risk of hemolysis.

With the simultaneous use of OD-Levox and warfarin, careful monitoring of prothrombin time and other coagulation indices is necessary.

It is recommended to carefully monitor the concentration of glucose in blood plasma with the simultaneous use of OD Levoksa with hypoglycemic drugs.

Because
levofloxacin is excreted mainly by the kidneys, in patients with impaired renal function, mandatory monitoring of kidney function is required, as well as correction of the dosing regimen. Very rare cases of prolongation of the QT interval in patients receiving fluoroquinolones, including levofloxacin, have been reported.When using fluoroquinolones, including levofloxacin, caution should be exercised in patients with known risk factors for prolonging the QT interval: elderly age, electrolyte imbalance (hypokalemia, hypomagnesemia), congenital QT interval prolongation, heart disease (heart failure, myocardial infarction, bradycardia), simultaneous administration of drugs that can extend the QT interval.
In patients receiving fluoroquinolones, including levofloxacin, sensory and sensory-motor peripheral neuropathy was noted, the onset of which can be rapid.
If the patient develops symptoms of neuropathy, the use of levofloxacin should be discontinued. This minimizes the possible risk of irreversible changes.
Impact on the ability to drive vehicles and manage mechanisms

During the treatment with OD-Levox, caution should be exercised when driving vehicles and engaging in other potentially hazardous activities requiring increased attention and speed of psychomotor reactions.

OVERDOSE

Symptoms: confusion, dizziness, impaired consciousness, convulsions, nausea, vomiting and erosive lesions of the mucous membranes are possible.
During the research it was shown that when levofloxacin is used in doses exceeding the average therapeutic levels, the QT interval may be prolonged.
Treatment: if necessary, conduct symptomatic therapy.
Levofloxacin is not excreted in hemodialysis, peritoneal dialysis and permanent peritoneal dialysis. There is no specific antidote.
DRUG INTERACTION

Quinolones can enhance the ability of drugs, including
theophylline, NSAIDs, lower the threshold of convulsive readiness. With simultaneous administration with fenbufen, higher concentrations of levofloxacin are observed than with monotherapy.
The effect of levofloxacin reduces drugs that depress intestinal motility, sucralfate, magnesium or aluminum-containing antacids, iron and zinc salts.

Acceptance of GCS increases the risk of rupture of tendons.

Levofloxacin increases the anticoagulant activity of warfarin.

Elimination (renal clearance) of levofloxacin is slightly slowed by cimetidine and probenecid in view of the possible blocking of tubular secretion of levofloxacin in the kidneys.
It should be noted that this interaction is of clinical importance, especially for patients with impaired renal function.
Levofloxacin increases T1 / 2 cyclosporine.

Simultaneous use of levofloxacin and hypoglycemic agents leads to a change in the concentration of glucose in the blood plasma (hypoglycemia and hyperglycemia).

With simultaneous use with drugs that extend the QT interval (antiarrhythmic IA and III classes, tricyclic and tetracyclic antidepressants, neuroleptics, macrolides, antifungal, imidazole derivatives, some antihistamines, including astemizole, terfenadine, ebastin), QT interval prolongation is possible.
