Mechanism of action

The optically active levorotatory isomer of Ofloxacin - L-ofloxacin (S - (-) - enantiomer). It has a broad spectrum of antimicrobial activity. Blocks bacterial topoisomerase IV and DNA gyrase (topoisomerase II). Violates supercoiling and cross-linking of DNA breaks, causes profound morphological changes in the cytoplasm and cell wall. In concentrations that are equivalent to or exceed the minimum inhibitory concentrations (BMD), most often has a bactericidal effect.The main mechanism of resistance development is associated with the mutation of the gyr-A gene with the possible development of cross-resistance between Levofloxacin and other fluoroquinolones. Cross-resistance between levofloxacin and antibacterial drugs of other classes usually does not occur.

Indications and usage

Infectious and inflammatory diseases caused by microorganisms susceptible to levofloxacin:

• acute bacterial sinusitis;
• exacerbation of chronic bronchitis;
• community-acquired pneumonia;
• complicated infectious diseases of the kidneys and urinary tract, including pyelonephritis;
• chronic bacterial prostatitis;
• infections of the skin and soft tissues.

Contraindications

Hypersensitivity to levofloxacin, to other quinolones or other components of the drug; epilepsy, including a history; history of tendon lesions associated with taking fluoroquinolones; children and adolescents up to 18 years; pregnancy; breastfeeding period.

Dosage and administration

Levofloxacin-Teva is taken orally 1-2 times a day. The dose and duration of treatment are determined by the nature and severity of the infection, as well as the sensitivity of the suspected pathogen. pills should be taken without chewing and drinking plenty of fluids (½ to 1 cup). When selecting doses, pills can be broken down into equal parts along the separation groove. The drug can be taken before meals or at any time between meals.
Treatment with Levofloxacin-Teva is recommended to continue for at least 48-72 hours after normalization of body temperature or after reliable eradication of the pathogen.
Acute bacterial sinusitis: 1 pill (500 mg) 1 time per day for 10-14 days.
Acute bronchitis and exacerbation of chronic bronchitis: on ½-1 pill (250-500 mg) once a day for 7-10 days.
Community-acquired pneumonia: 1 pill (500 mg) 1-2 times a day for 7-14 days.
Complicated infectious diseases of the kidneys and urinary tract, including pyelonephritis: on ½ pill (250 mg) once a day for 7-10 days.
Chronic bacterial prostatitis: 1 pill (500 mg) 1 time per day for 28 days.
Skin and soft tissue infections: 1 pill (500 mg) 1-2 times a day for 7-14 days.
Patients with impaired liver function correction dosage is not required.
Patients with impaired renal function (QC less than 50 ml / min) correction of the dosage regimen is required depending on the QC value.

Special notes

When levofloxacin was used, cases of tendinitis were observed, which mainly affects the Achilles tendon and can lead to its rupture. In elderly patients, as well as with the concomitant use of GCS, the likelihood of tendinitis and tendon rupture when using levofloxacin increases. If you suspect that you have tendonitis, you should immediately cancel levofloxacin and begin appropriate treatment, ensuring a state of rest in the affected area.
If pseudomembranous colitis is suspected (diarrhea appears, in particular, severe and / or with blood), levofloxacin should be discontinued and appropriate treatment should be initiated.
During treatment with levofloxacin, a seizure seizure may develop in patients with previous brain damage (including stroke or severe brain injury).
When quinolones are used in patients with glucose-6-phosphate dehydrogenase deficiency, erythrocyte hemolysis is possible.
If you need to use levofloxacin in patients with diabetes, it is necessary to control the concentration of glucose in the blood.
Sometimes, after taking the first dose of levofloxacin, severe, potentially dangerous hypersensitivity reactions may develop (angioedema, anaphylactic shock).
Despite the fact that photosensitivity is observed when levofloxacin is used very rarely, patients should avoid exposure to the sun or UV radiation to prevent its development.
With simultaneous use of levofloxacin and indirect anticoagulants, it is necessary to monitor the state of the blood coagulation system.
When you take fluoroquinolones, including levofloxacin, you may develop psychotic reactions, which very rarely can lead to suicidal thoughts and potentially dangerous behavior during progression. With the development of such phenomena, the drug should be discontinued.
When levofloxacin is used in patients who have predisposing factors to prolonging the QT interval, an electrocardiogram should be investigated before and during levofloxacin treatment.
When taking fluoroquinolones, cases of the development of sensory or sensorimotor peripheral neuropathy were observed. To prevent the development of irreversible effects in the development of symptoms of peripheral neuropathy, levofloxacin should be immediately canceled.
Patients may receive false-positive tests for the presence of opiates in the urine when taking levofloxacin in patients. To confirm a positive test result, more specific methods should be used.
There are reports of rare cases of liver failure during treatment with levofloxacin, primarily in patients with serious illnesses such as sepsis. If symptoms of liver dysfunction, such as loss of appetite, jaundice, dark urine, itching or sensitivity of the abdominal wall during palpation, levofloxacin should be canceled.
When prescribing the drug to elderly patients, it should be borne in mind that patients in this group often have impaired renal function.

Drug Interactions

Levofloxacin absorption is significantly reduced with simultaneous use with sucralfate, magnesium- or aluminum-containing antacid agents, as well as with iron salts (the interval between taking levofloxacin and these medicines should be at least 2 hours). No interaction with Calcium carbonate has been identified.
Quinolones can enhance the ability of drugs (including theophylline) to lower the threshold of convulsive readiness. When taken simultaneously with fenbufen, higher concentrations of levofloxacin were observed (by 13%) than with monotherapy.
Levofloxacin elimination slows down under the action of cimetidine (by 24%) and probenecid (by 34%).
Levofloxacin causes a slight increase in T1/2 cyclosporine.
Simultaneous administration with glucocorticosteroids (GCS) increases the risk of tendon rupture.
The simultaneous intake of levofloxacin with oral anticoagulants increases the coagulation time and / or bleeding.
Levofloxacin with simultaneous use with class IA and III antiarrhythmic drugs, tricyclic antidepressants, macrolides can cause prolongation of the QT interval.

Overdosage

Treatment: conduct symptomatic therapy, ECG monitoring. There is no specific antidote. Hemodialysis is not effective.
