Abiflox is an antimicrobial drug from the subspecies of fluoroquinolones. The drug has inhibitory properties on the DNA group of hydrase and topomerase IV, which leads to a failure in the production of pathogenic bacterial cells and leads to the destruction of the disease.
Indications for the use of Abiflox are:
Abiflox is used as an infusion solution. The substance should be used for 3 hours after opening the vial. The solution does not require protection from light. The solution should be administered for a long time drip (100 ml of solution is injected throughout 1 o'clock).
| Recommended Therapeutic Doses | ||
| Type of disease | Dose | Number of doses |
| Inflammatory processes of the lung tissue | 500 mg | 1-2 once a day |
| Inflammatory processes of the urinary system | 250 mg | 1 once a day |
| Inflammatory processes of the prostate gland | 500 mg | 1 once a day |
| Inflammatory processes of the skin, soft tissue | 500 mg | 1-2 once a day |
After 3-4 days after the start of taking Abiflox, you should switch to taking oral forms of the drug. In severe stages of the disease, an increase in the standard dose is allowed.. Patients with kidney dysfunction with GFR have less 50 ml / min recommended reduction in the rate of medication:
When undergoing hemodialysis, additional doses of the drug should not be administered immediately after the end of the procedure.. The course of therapy is determined by the course of the disease, but the duration of treatment after leveling the temperature reactions should be carried out for 2-3 days.
When using large doses of Abiflox, the following types of symptoms develop:
As a therapy against an overdose with Abiflox, treatment should be prescribed according to the identified symptoms.. No specific treatment has been developed. Hemodialysis is not effective for removing the active substance of the drug.
Possible negative reactions are transient and decrease after discontinuation of therapy. In case of individual intolerance develop:
The drug is not used in people with high sensitivity to levofloxacin or other types of quinolones. Abiflox is not recommended for patients with epilepsy., reactive manifestations from the tendons to the introduction of quinolones. Levofloxacin is not prescribed in the pediatric age group.
The effect of the drug on the reaction rate when driving a car and heavy machinery
Patients should take into account the possible adverse reactions of the nervous system when driving vehicles and heavy machinery.:
Abiflox is not recommended for use during pregnancy and breastfeeding due to the risk of negative effects on the osteoarticular system of the fetus and newborn. If the drug is prescribed during lactation, it is necessary to stop breastfeeding for the entire period of therapy..

Abiflox is an antimicrobial agent from the group of fluoroquinolones. The drug has an inhibitory effect on the complex of DNA hydrase and topomerase IV, which leads to disruption of bacterial cell synthesis and leads to the death of the microbial agent. Given the mechanism of action of the drug, it lacks cross-resistance between other groups of antimicrobials, but exists between groups of fluoroquinolones.
The drug is active in relation to grams (+) aerobic: Staph.saprophyticus, Strep, the group with the, G, Strep.agalactiae, Strep.pneumoniae, pyogenes;
aerobic grams (-) microorganisms: Burkholderia cepacia, Eikenella corrodens, H. influenzae, parainfluenzae, Klebsiella oxytoca, pneumoniae, Moraxella catarrhalis, Pasteurella multocida, Pr.vulgaris, Rettgeri Providence; anaerobic peptostreptococci, chlamydia, legionella, mycoplasmas, ureaplasma.
After infusion, leofloxacin accumulates in bronchial secretions and bronchi, lung tissue, urine, minimal in cerebrospinal fluid. Preparation of 40% binds to blood proteins. Metabolized slightly in the liver. Период полувыведения – 6-8 hours. Eliminated through the kidneys 85%.

Absorption
There is no significant difference in the pharmacokinetics of levofloxacin after intravenous and oral administration..
After intravenous administration, the drug accumulates in the bronchial mucosa and bronchial secretion of lung tissue. (concentration in the lungs exceeds that in blood plasma), Urine. Levofloxacin enters the cerebrospinal fluid poorly.
Distribution
About 30 – 40% levofloxacin binds to serum protein. Cumulative effect of levofloxacin when administered 500 mg 1 once a day repeated use is practically absent. There is a slight, but the expected cumulative effect after application of doses according to 500 mg twice a day. Steady state is reached within 3 days.
Penetration into tissues and body fluids
Penetration into the bronchial mucosa, bronchial secretion of lung tissue (BSTL)
The maximum concentration of levofloxacin in the bronchial mucosa and bronchial secretion of the lungs after application 500 mg orally were 8,3 g / and g 10,8 g / ml respectively. These indicators were achieved within one hour after taking the drug..
Penetration into lung tissue
Maximum concentrations of levofloxacin in lung tissues after application 500 mg orally were approximately 11,3 g / g and were achieved through 4 – 6:00 after drug use. The concentration in the lungs exceeds that in the blood plasma.
Penetration into the contents of the bubble
Maximum concentrations of levofloxacin 4,0 – 6,7 g / ml per bubble content reached through 2 – 4:00 after drug administration 3 days of drug administration at doses 500 mg 1 once or twice a day, respectively.
Penetration into the cerebrospinal (spinal) fluid
Levofloxacin does not penetrate well into the CSF..
Penetration into prostate tissue
After application 500 mg levofloxacin 1 once a day for 3 days, the average concentrations in the prostate tissue reached 8,7 g / g, 8,2 g / and g 2,0 g / g respectively through 2:00, 6:00 on 24 o'clock; average prostate concentration ratio / plasma was 1,84.
Concentration in urine
Average concentration in urine 8 – 12:00 after a single oral dose 150 mg, 300 mg or 500 mg of levofloxacin were 44 mg / l, 91 mg / and l 200 mg / l, respectively.
Metabolism
Levofloxacin is metabolized to a very small extent, metabolites are dismethyl-levofloxacin and levofloxacin N-oxide. These metabolites are less than 5% quantities of preparation, which is excreted in the urine. Levofloxacin is stereochemically stable and is not subject to choral structure inversion.
Conclusion
After administration and administration, levofloxacin is excreted from the blood plasma relatively slowly. (half-life is 6 – 8:00). Excreted usually through the kidneys (85% of the administered dose).
There is no significant difference in the pharmacokinetics of levofloxacin after intravenous and oral administration., which indicates that, that these paths (oral and intravenous routes of administration) are interchangeable.
