ATX Code J01FA10
After a single oral administration, the bioavailability of azithromycin is 37%. The maximum concentration of azithromycin in the blood plasma is achieved in 2-3 hours after administration.
After oral administration, azithromycin is rapidly distributed in tissues and body fluids. It penetrates well into the respiratory tract, organs and tissues of the urogenital tract, into the skin and soft tissues. It accumulates intracellularly, as a result of which the concentrations of azithromycin in tissues are much higher (by 50 times) than in plasma, which indicates a high affinity of azithromycin for tissues and a low binding of azab 100 to plasma proteins.
The concentrations of azithromycin in the target organs (lungs, tonsils, prostate gland) exceed MIC90 for pathogenic microorganisms after taking a single dose of the drug 500 mg. Azithromycin is accumulated in large amounts in phagocytes. Phagocytes transport the drug to the site of inflammation.
The elimination half-life is from 2 to 4 days.
About 12% of the administered dose of azithromycin is excreted in the urine unchanged for the next 3 days. Especially high concentrations of unchanged azab 100 have been detected in bile. Identified 10 metabolites that are formed with the help of N- and O-demethylation, hydroxylation and other metabolic transformations. Appropriate studies have confirmed that the metabolites of azithromycin do not exhibit antimicrobial effects.
In patients with mild to moderate renal failure (creatinine clearance 10-80 ml / min) who took 1 g of azithromycin, the mean Cmax and AUC0-120 once increased by 5.1% and 4.2%. In patients with severe renal failure, the mean Cmax and AUC0-120 increased by 61% and 35%, compared with people with normal renal function (creatinine clearance> 80 mL / min).
In patients with mild to moderate hepatic impairment, there is no evidence of a pharmacokinetic change in azithromycin compared to patients with normal liver function. In such patients there is an increased excretion of azab 100 in the urine, possibly to compensate for a decreased hepatic clearance.
The pharmacokinetics of azithromycin in elderly and young patients are the same. However, the maximum concentration of azithromycin in the plasma was higher (by 30-50%) in elderly patients, but no accumulation was observed.
Pharmacokinetics was studied in children aged 4 months to 15 years who took capsules, granules and suspension. At a dose of 10 mg / kg on the first day, followed by a dose of 5 mg / kg from day 2 to day 5, the Cmax achieved was slightly lower than in adults.
Active substance of the drug azab 100- azithromycin is a broad-spectrum antibiotic, the first representative of a new subgroup of macrolide antibiotics – azalides.
It has a bacteriostatic effect, but when creating high concentrations in the focus of inflammation, it causes a bactericidal effect.
The mechanism of action is based on inhibiting the synthesis of proteins in bacteria by binding to 50-S ribosomal subunits and preventing the translocation of peptides.

To prepare 20 ml of suspension (for a dosage of 100 mg / 5 ml), it is necessary:
- shake dry powder thoroughly in a vial;
- open the lid of the vial and place the adapter in the neck of the vial;
- draw in a syringe 10 ml of cooled boiled water;
- place the tip of the syringe in the adapter;
- add 10 ml of water from the syringe and shake well until a homogeneous suspension is obtained from white to almost white.
