Active ingredient

Composition

Composition per 100 ml of the drug:

Active ingredient: Levofloxacin hemihydrate (in terms of Levofloxacin) – 500 mg;

How to take, the dosage

Intravenously drip slowly 1-2 times a day. Doses are determined by the nature and severity of the infection, as well as the sensitivity of the suspected pathogen.

Patients with normal renal function (creatinine clearance >50 ml/min) may be recommended the following dosing regimen:

Out-of-hospital pneumonia: 500 mg of levofloxacin (100 ml of drug) 1-2 times a day, for 7-14 days;

uncomplicated urinary tract infections: 250 mg of levofloxacin (50 ml of the drug) once a day for 3 days;

complicated urinary tract infections (including acute pyelonephritis): 250 mg of levofloxacin (50 ml of the drug) once a day, for 7-10 days;

Skin and soft tissue infections (suppurated atheromas, abscesses, furuncles): 500 mg (100 ml of the drug) 2 times a day, for 7-14 days.

Chronic bacterial prostatitis: 500 mg of levofloxacin (100 ml of drug) once daily, for 28 days;

Septicemia/bacteremia: 500 mg of levofloxacin (100 ml of the drug) 1-2 times daily, for 10-14 days;

intraabdominal infection: 500 mg of levofloxacin (100 ml of drug) once daily, for 7-14 days (in combination with antibacterials acting on anaerobic flora).

Patients with impaired renal function require adjustment of the dosing regimen depending on the creatinine clearance value.

Interaction

When combined treatment with phenbufen and similar non-steroidal anti-inflammatory drugs, theophylline, the drug may increase the seizure threshold.

Glucocorticoids increase the risk of tendon rupture (especially in the elderly).

Levofloxacin excretion is slightly delayed by cimetidine and probenecid. Levofloxacin causes a slight increase in the blood plasma elimination half-life of cyclosporine.

Concomitant use with warfarin increases prothrombin time and risk of bleeding (close monitoring of INR; prothrombin time and other coagulation indices, as well as monitoring of possible bleeding signs is necessary).

Alcohol may exacerbate central nervous system side effects (dizziness, somnolence).

In diabetic patients receiving oral hypoglycemic agents or insulin hypo- and hyperglycemic states are possible while taking levofloxacin (close monitoring of blood glucose concentration is recommended).

In concomitant use with drugs prolonging the QT interval (antiarrhythmic drugs of classes IA and III, tricyclic and tetracyclic antidepressants, neuroleptics, macrolides, antifungals, imidazole derivatives, some antihistamines, including astemizole, terfenadine, ebastine) QT interval prolongation is possible.

Special Instructions

In severe pneumonia caused by pneumococci, the therapeutic effect of Leflobact may be insufficient.

After normalization of body temperature, it is recommended to continue treatment for at least 48-72 hours.

The duration of intravenous infusion of 500 mg (100 ml infusion solution) should be at least 60 minutes.

A sensation of palpitation; transient decrease of blood pressure may be observed in individual cases during the infusion. If there is a significant decrease in blood pressure, the infusion should be stopped immediately.

At the time of treatment it is necessary to avoid sunlight and artificial ultraviolet irradiation in order to avoid skin damage (photosensitization).

In case of signs of tendinitis, pseudomembranous colitis and allergic reactions levofloxacin should be stopped immediately.

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

Contraindications

Elderly age, due to the high likelihood of concomitant decreased renal function (glucose-6-phosphate dehydrogenase deficiency).

In patients with brain damage; history (stroke or severe trauma) (possible development of seizures).

In patients with pseudoparalytic myasthenia gravis; with known risk factors for QT interval prolongation.

In patients with diabetes mellitus.

The use of levofloxacin concomitantly with other QT interval prolonging agents is not recommended because the risk of cardiac arrhythmias increases.

Predisposition to seizure reactions (cerebral atherosclerosis, cerebral circulatory disorders (in anamnesis), organic diseases of the central nervous system), renal failure, congenital prolongation of the QT interval syndrome, heart disease (heart failure, myocardial infarction, bradycardia), electrolyte imbalance (e.g. in hypokalemia, hypomagnesemia), psychosis and other mental disorders in the history, hepatic porphyria/ concurrent use of drugs that prolong the QT interval, (antiarrhythmic drugs of classes IA and III, tricyclic and tetracyclic antidepressants, neuroleptics, macrolides, antifungals, imidazole derivatives, some antihistamines, including astemizole, terfenadine, ebastine) and lowering the threshold, seizure readiness of the brain (phenbufen, theophylline).
