Pharmacological action

Broad-spectrum antibiotic of macrolides, azalid.

Valid bacteriostatic. Communicating with the 50S-subunit of ribosomes, inhibits protein synthesis and slows the growth and multiplication of bacteria. In high concentrations, has a bactericidal effect. Operates on extra-and intracellular pathogens.

It is active against Gram-positive microorganisms: Streptococcus spp. (Groups C, F and G, except for resistance to erythromycin), Streptococcus pneumoniae, Streptococcus pyogenes, Streptococcus agalactiae, Streptococcus viridans, Staphylococcus epidermidis, Staphylococcus aureus; Gram-negative bacteria: Haemophilus influenzae, Moraxella catarrhalis, Bordetella pertussis, Bordetella parapertussis, Legionella pneumophila, Haemophilus ducreyi, Campylobacter jejuni, Neisseria gonorrhoeae and Gardnerella vaginalis; some anaerobic microorganisms: Bacteroides bivius, Clostridium perfringens, Peptostreptococcus spp., as well as intracellular pathogens: Chlamydia trachomatis, Chlamydia pneumoniae, Mycoplasma pneumoniae, Mycobacterium avium complex, Ureaplasma urealyticum, Treponema pallidum, Borrelia burgdoferi.

Azithromycin is not active against gram-positive bacteria resistant to erythromycin.



After taking the drug inside azithromycin is rapidly absorbed from the gastrointestinal tract, due to its stability in acidic medium and lipophilicity. After receiving the oral dose of 500 mg Cmax in the plasma is achieved through 2.5-2.9 h and is 0.4 mg / liter. Bioavailability - 37.5%.


Azithromycin is quickly distributed throughout the body, while in the tissues reached high concentrations of antibiotic. Well into the respiratory tract, organs and tissues of the urogenital tract (in particular, in the prostate gland), in skin and soft tissue. The high concentration in tissues (10-50 times higher than in blood plasma) and a long T1 / 2 due to low binding of azithromycin from plasma proteins, as well as its ability to penetrate into eukaryotic cells and concentrate in an environment with low pH, environmental lysosomes. This, in turn, defines a large apparent Vd (31.1 L / kg) and high plasma clearance. The ability of azithromycin to accumulate mainly in lysosomes is particularly important for elimination of intracellular pathogens. Shown that phagocytes deliver azithromycin to the localization of infection sites, where it is released during phagocytosis. The concentration of azithromycin in the foci of infection was significantly higher than in healthy tissues (on average 24-34%) and correlated with the degree of inflammatory edema. Despite the high concentration in phagocytes, azithromycin did not significantly affect their function. Azithromycin remains in bactericidal concentrations of inflammation within 5-7 days after receiving the last dose, which allowed the development of short (3-day and 5-day) courses of treatment.


Azithromycin is metabolized in the liver by demethylation with the formation of inactive metabolites.


Withdrawal of azithromycin from plasma takes place in two stages: T1 / 2 was 14-20 h in the range of 8 to 24 h after drug administration and 41 h - in the range of 24 to 72 hours, which allows to use a drug once a day. Derive mainly from the bile in unchanged form, a small part is displayed by the kidneys.

Drug Interactions

With simultaneous use of antacids (aluminum and magnesium), ethanol and food slow down and reduce the absorption of azithromycin.

When the joint application AzitRus at therapeutic doses with warfarin prothrombin time change is not mentioned, but considering that the interaction of macrolides with warfarin may be increased anticoagulation effect when assigning patients to this combination requires careful monitoring prothrombin time.

With the simultaneous application of increasing concentrations of digoxin in the blood plasma.

With simultaneous application of enhanced toxicity (vasospasm, dysesthesia), ergotamine and dihydroergotamine.

With simultaneous application of decreasing clearance and increasing the pharmacological effect triazolama. Azithromycin inhibits microsomal oxidation in hepatocytes, which leads to slower excretion and increase of plasma concentrations and toxicity of cycloserine, indirect anticoagulants, methylprednisolone, felodipina, as well as preparations exposed to microsomal oxidation (carbamazepine, terfenadin, cyclosporine, geksobarbital, ergot alkaloids, valproic acid, dizopiramid, bromocriptine, phenytoin, oral hypoglycemic means, xanthine derivatives, including theophylline). Linkozaminy reduce the effectiveness of azithromycin. Tetracycline and chloramphenicol enhance the effectiveness of azithromycin.
