Pharmacological action:
The broad-spectrum antibiotic from macrolides group, ozalid. Acts bacteriostatically. Binding to 50S-subunit of ribosomes, inhibits protein synthesis and slows the growth and reproduction of bacteria. In high concentrations has a bactericidal effect. It acts on extracellular and intracellular pathogens.
Active against gram-positive microorganisms: Streptcccus spp. (groups C, F and G, except for resistant to erythromycin), Streptcccus pneumniae, Streptcccus pygenes, Streptcccus agaactiae, Streptcccus viridans, epidermidis Staphycccus, Staphycccus aureus gram negative bacteria: Haemphius infuenae, Mraxea catarrhais, Brdetea pertussis, parapertussis Brdetea, Leginea pneumphia, Haemphius ducreyi, Campybacter jejuni, Neisseria gnrrheae and Gardnerea vaginais some anaerobic microorganisms: Bacterides bivius, Cstridium perfringens, Peptstreptcccus spp. and also intracellular pathogens: Chamydia trachmatis, Chamydia pneumniae, Mycpasma pneumniae, Mycbacterium avium cmpex, Ureapasma ureayticum, Trepnema paidum, Brreia burgdferi.
Azithromycin is not active against gram-positive bacteria resistant to erythromycin.
Pharmacokinetics:
Suction
After taking the drug inside azithromycin is rapidly absorbed from the gastrointestinal tract due to its stability in acidic medium and lipophilicity. Once inside the dose of 500 mg Cmax in plasma achieved through 2.5-2.9 h and is 0.4 mg/l. Bioavailability is 37.5%.
Distribution
Azithromycin is rapidly distributed throughout the body, with high concentrations of antibiotic in tissues. It penetrates well into the respiratory tract, organs and tissues of the urogenital tract (in particular, the prostate gland), into the skin and soft tissues. High concentration in tissues (10-50 times higher than in blood plasma) and long T1/2 due to low binding of azithromycin to plasma proteins of blood, as well as its ability to penetrate into eukaryotic cells and concentrate in an environment with low pH, environmental lysosomes. This in turn determines the large apparent Vd (31.1 l/kg) and the high plasma clearance. The ability of azithromycin to accumulate mainly in lysosomes is especially important for the elimination of intracellular pathogens. It is proved that phagocytes deliver azithromycin to the sites of infection localization, where it is released in the process of phagocytosis. The concentration of azithromycin in the foci of infection is significantly higher than in healthy tissues (on average 24-34%) and correlates with the degree of inflammatory edema. Despite the high concentration in phagocytes, azithromycin has no significant effect on their function.
Azithromycin remains in bactericidal concentrations in inflammation within 5-7 days after the last dose, which allowed to develop a short (3-day and 5-day) courses of treatment.
Metabolism
Azithromycin is metabolized in the liver by demethylation to form inactive metabolites.
Breeding
Removal of azithromycin from blood plasma takes place in 2 stages: T1/2 is 14-20 h in the range of 8 to 24 h after taking the drug and 41 h – in the range of 24 to 72 h, which allows the drug 1 time/day.
Excreted mainly jelchew in an unmodified form, a small part is excreted by the kidneys.

Drug interaction:
With the simultaneous use of antacids (aluminum - and magnesium-containing), ethanol and food slow down and reduce the absorption of azithromycin.
In a joint application of azithromycin at therapeutic doses of warfarin, changes in prothrombin time were noted, however, that the interaction of macrolides with warfarin may increase anticoagulant effect, when you assign this combination to patients requires careful monitoring of prothrombin time.
