Pharmacological action
Remedia is an antimicrobial drug from the group of fluoroquinolones, a levorotatory isomer of ofloxacin. It has a wide spectrum of antimicrobial action. Levofloxacin blocks DNA gyrase (topoisomerase II) and topoisomerase IV, disrupts supercoiling and crosslinking of DNA breaks, inhibits DNA synthesis, and causes deep morphological changes in the cytoplasm, cell wall, and membranes of bacteria. Levofloxacin is active against most strains of microorganisms both in vitro and in vivo. vivo.

Pharmacokinetics
Distribution
Protein binding is 30-40%. Accumulation at a dose of 500 mg 1 time / day is insignificant. When administered at a dose of 500 mg 2 times/day, accumulation may occur to a small extent. Css is reached 3 days after the application starts.
It penetrates well into organs and tissues: lungs, bronchial mucosa, sputum, urinary system organs, genitals, bone tissue, prostate gland, polymorphonuclear leukocytes, alveolar macrophages. Levofloxacin does not penetrate well into the cerebrospinal fluid.
Mean urinary concentrations 8-12 hours after a single use of 150,300, or 500 mg of levofloxacin were 44,91, and 200 g/l, respectively.
Metabolism
In the liver, a small portion of levofloxacin is metabolized to form desmethylvofloxacin and levofloxacin-N-oxide, which constitute
Deduction
After use in a single dose of 500 mg, T1 / 2 is 6-8 hours. It is excreted mainly by the kidneys through glomerular filtration and tubular secretion. Less than 5% of levofloxacin is excreted as metabolites. 70% is excreted unchanged and 87% in 48 hours.
Indications
- Infectious and inflammatory diseases caused by microorganisms sensitive to levofloxacin;
- lower respiratory tract infections (exacerbations of chronic bronchitis, community-acquired pneumonia);
- acute maxillary sinusitis;
- uncomplicated urinary tract infections;
- complicated urinary tract infections (including acute pyelonephritis):
- skin and soft tissue infections (suppurated atheromas, abscesses, boils);
- septicemia/bacteremia;
- chronic bacterial prostatitis;
- intra-abdominal infection;
- complex therapy of drug-resistant forms of tuberculosis.
Use during pregnancy and lactation
The drug is contraindicated during pregnancy and lactation.
Contraindications

- pregnancy;
- lactation;
- children and adolescents (up to 18 years);
- hypersensitivity to levofloxacin, any other component of the drug or other drugs from the group of fluoroquinolones.
With caution: Â older age (high probability of having a concomitant decrease in renal function), deficiency of glucose-6-phosphate dehydrogenase in patients with brain lesions in history (stroke, or severe trauma), in patients receiving both drugs that reduce the threshold of convulsive readiness of the brain (perhaps the development of seizures) in patients with psevdoparaliticheskimi myasthenia (myasthenia grais), with known risk factors for QT interval prolongation.

Interaction
Levofloxation increases the T1 / 2 of cyclosporine.
NSAIDs, theophylline increase the risk of developing seizures.
Taking corticosteroids increases the risk of tendon rupture (especially in the elderly).
Cimetidine and drugs that block tubular secretion slow down the elimination of levofloxacin.
The infusion solution 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 a solution of sodium bicarbonate).
In patients with diabetes mellitus receiving oral hypoglycemic agents or insulin, hypo – and hyperglycemic conditions are possible against the background of levofloxacin use, so monitoring of blood glucose concentration is recommended.
Levofloxacin enhances the anticoagulant activity of warfarin
Alcohol can increase the side effects of the central nervous system (dizziness, numbness, drowsiness).
How to take, course of use and dosage
Remedia tablets are prescribed for adults 1-2 times a day.
Dosage depends on the type and severity of infection, the sensitivity of the suspected or isolated microorganism that is the causative agent of the disease.
The duration of treatment varies depending on the disease, with a maximum duration of treatment of 14 days, with bacterial prostatitis, up to 28 days are possible.
In accordance with the general principles of antibiotic therapy, taking Remedia tablets should be continued for at least 48-72 hours after normalization of body temperature or receiving a negative bacteriological analysis.
Remedia tablets are taken orally, without chewing, with a sufficient amount of liquid. For the recommended dosage, tablets should be divided along the fault line. Tablets can be taken during meals or between meals. Remedia tablets should be taken 2 hours before taking iron salts, antacids and sucralfate due to a possible decrease in absorption.
Overdose
Symptoms:Â They are mainly manifested from the central nervous system (confusion, dizziness, impaired consciousness and seizures like epileptic seizures).
In addition, gastrointestinal disorders (for example, nausea) and erosive lesions of the gastrointestinal mucosa, prolongation of the QT interval may occur.
Treatment:Â symptomatic. Dialysis is ineffective. The specific antidote is not known.
Special instructions
When the body temperature normalizes, it is recommended to continue treatment for at least 48-72 hours.
During treatment, it is necessary to avoid sun and artificial ultraviolet radiation in order to avoid damage to the skin (photosensitization). If signs of tendinitis, pseudomembranous colitis, or allergic reactions occur, levofloxacin is immediately discontinued.
It should be borne in mind that patients with a history of brain damage (stroke or severe injury) may develop seizures, with glucose-6-phosphate dehydrogenase deficiency, the risk of developing hemolysis of red blood cells.
Alcohol consumption should be avoided during treatment.
Influence on the ability to drive motor vehicles and manage mechanisms
During the treatment period, care should be taken when driving a car and potentially dangerous mechanisms due to the possible appearance of dizziness, drowsiness, stiffness and visual disturbances, which can lead to a slowdown in the speed of psychomotor reactions and a decrease in the ability to concentrate.
