Description

Levofloxacin Pharmacodynamics
Levofloxacin is a synthetic antibiotic of the group of fluoroquinolones, optically active left-handed isomer ofloxacin – (-)-(8)-enantiomer. It has a wide spectrum of antimicrobial activity.
It inhibits DNA-enzyme (topoisomerase II) and topoisomerase IV, breaks supercoiling and cross-linking of DNA, inhibits DNA replication, causes profound morphological changes in cytoplasm, cell wall and membranes of microorganisms.
Levofloxacin is active against most strains of microorganisms both in vitro and in vivo.

Indications
Treatment of infectious and inflammatory diseases caused by microorganisms sensitive to levofloxacin:
– community-acquired pneumonia;
– complicated urinary tract infections, including pyelonephritis;
– chronic bacterial prostatitis;
– Skin and soft tissue infections;
– For the complex treatment of drug-resistant forms of tuberculosis;
– Prevention and treatment of anthrax with an airborne route of infection.
For treatment of the following infectious and inflammatory diseases Levofloxacin may be used only as an alternative to other antimicrobial agents:
– uncomplicated cystitis.
When using Levofloxacin, the official national recommendations on the appropriate use of antibacterial agents as well as the sensitivity of pathogens in a particular country should be taken into account (see section “Special indications”).

Contraindications
Hypersensitivity to levofloxacin, excipients of the drug or other quinolones; epilepsy; tendon lesions when using fluoroquinolones in the anamnesis; pseudoparalytic myasthenia gravis; childhood and adolescence before 18 years of age (due to incomplete skeletal growth, as the risk of cartilaginous growth points damage cannot be completely excluded); pregnancy (the risk of fetal cartilaginous growth points damage cannot be completely excluded); breastfeeding (the risk of cartilaginous bone growth points damage in the child cannot be completely excluded).

Dosage and administration method

  • Intravenous drip.
  • Dosage regimen and duration of treatment are determined by the localization, nature and severity of the infection, as well as the sensitivity of the suspected pathogen. Treatment shall not be interrupted or terminated prematurely without the physician’s instructions.
  • Depending on the patient’s condition and the possibility of taking medicines per os, after several days of treatment it is possible to switch from intravenous infusion to taking the same dose of the drug in tablets (due to the fact that the bioavailability of levofloxacin when taking tablets is 99-100 %).
  • If the drug is accidentally missed, the missed dose should be administered as soon as possible and then levofloxacin should be continued according to the recommended dosing regimen.
  • Recommended dosing regimen and duration of treatment in patients with normal renal function (CKG >50 ml/min):
