Pharmacological properties

Pharmacodynamics

Azithromycin Forte-OBL is a broad-spectrum macrolide antibiotic, azalide, has bacteriostatic properties. It binds to the 50S subunit of the ribosome, thereby inhibiting protein synthesis, slowing down the growth and reproduction of bacteria. In the case of high doses, it has a bactericidal effect.

Acts on intra- and extracellular pathogens. Shows activity against the following microorganisms:

• aerobic gram-positive and gram-negative microorganisms: Streptococcus pneumonia (penicillin susceptible), Staphylococcus aureus (methicillin susceptible), Streptococcus pyogenes, Haemophilus parainfluenza, Haemophilus influenzae, Passeria gonorrhoeila, Neisseria gonorrhoeila;
• some anaerobic microorganisms: Prevotella spp., Fusobacterium spp., Clostridium perfringens, Porphyromonas spp.;
• other pathogens: Borrelia burgdorferi, Mycoplasma hominis, Chlamydia trachomatis, Chlamydia psittaci, Chlamydia pneumoniae, Mycoplasma pneumoniae.

Insensitive or moderately sensitive to the action of the drug, aerobic gram-positive microorganisms - Streptococcus pneumonia (moderately sensitive or resistant to penicillin).

Azithromycin Forte-OBL is not active against the following microorganisms:

• aerobic gram-positive microorganisms: Enterococcus faecalis, Staphylococcus spp. (methicillin resistant);
• anaerobes of the Bacteroides fragilis group.

Beta-hemolytic Streptococcus spp. group A, Streptococcus pneumonia, Enterococcus faecalis and Staphylococcus aureus (including methicillin-resistant strains), which are resistant to erythromycin and other macrolides and lincosamides, also show resistance to azithromycin.

Pharmacokinetics

Azithromycin is rapidly absorbed from the gastrointestinal tract, this is due to the stability of the substance in an acidic environment and lipophilicity. After ingestion, it is rapidly distributed throughout the body, while high concentrations of the antibiotic are observed in the tissues. The time to reach C _max (maximum concentration of the substance) after oral administration at a dose of 500 mg is from 2.5 to 2.9 hours, C _max is 0.4 mg / l, bioavailability is 37.5%.

Azithromycin is characterized by good penetration into the respiratory tract, tissues and organs of the urogenital tract (including the prostate gland), soft tissues and skin.

The substance binds to blood plasma proteins at a low level, is able to penetrate into eukaryotic cells and concentrate in an environment with a low pH that surrounds lysosomes. This provides a high tissue concentration (10-50 times higher than plasma concentration) and a long T _1/2 (half-life). It also causes a large apparent V _d (volume of distribution), namely 31.1 l / kg, and a high plasma clearance. For the elimination of intracellular pathogens, the ability of azithromycin to accumulate mainly in lysosomes is especially important.

It has been reliably established that phagocytes deliver azithromycin to the sites of infection, after which it is released during phagocytosis. In the foci of infection, the concentration of azithromycin is significantly higher than in healthy tissues (the average excess is 24–34%), this value correlates with the degree of inflammatory edema.

After taking the last dose, the substance remains in bactericidal concentrations for 5-7 days. As a result, short courses of treatment (3 and 5 days) have been developed.

The demethylation process occurs in the liver, the metabolites formed during this process do not show activity.

Azithromycin is excreted from blood plasma in two stages (depending on the interval that has passed after administration): in the interval of 8-24 hours T _1/2 is 14-20 hours, in the interval of 24-72 hours - 41 hours. Thanks to this, Azithromycin Forte-OBL can be taken once a day.

Excretion of azithromycin occurs mainly with bile in the form of an unchanged substance, a small part of the dose is excreted by the kidneys.

Indications for use

Azithromycin Forte-OBL is intended for the treatment of diseases of an infectious and inflammatory nature, which are caused by microorganisms sensitive to the action of the drug:

• infections of the ENT organs and upper respiratory tract, including otitis media, tonsillitis, sinusitis, pharyngitis;
• bacterial infections of the lower respiratory tract, including those caused by atypical pathogens, exacerbation of chronic bronchitis, pneumonia;
• infections of soft tissues and skin, including impetigo, erysipelas, secondarily infected dermatoses;

special instructions

Azithromycin Forte-OBL should not be taken with food.

If a dose is missed, it should be taken as early as possible and the next dose should be taken 24 hours later.

If it is necessary to use it simultaneously with antacids, the break should be at least two hours.

Hypersensitivity reactions after discontinuation of therapy in some cases may persist, and specific treatment is required under medical supervision.

For Streptococcus pyogenes pharyngitis and tonsillitis, penicillins are the antibacterial drugs of choice. The effectiveness of the use of Azithromycin Forte-OBL for the prevention of rheumatic fever has not been established.

Against the background of the use of azithromycin, as in the case of therapy with other antibiotics, superinfection (including fungal) may develop.

Influence on the ability to drive vehicles and complex mechanisms

During the period of taking Azithromycin Forte-OBL, you should refrain from driving.

Application during pregnancy and lactation

• pregnancy: therapy with Azithromycin Forte-OBL is possible only in cases where the expected benefit is higher than the potential harm;
• period of breastfeeding: the use of the drug is contraindicated.

Pediatric use

It is contraindicated to prescribe Azithromycin Forte-OBL to patients under 12 years of age with a body weight of less than 45 kg.

With impaired renal function

• severe renal failure: taking Azithromycin Forte-OBL is contraindicated;
• moderate renal dysfunction: therapy should be carried out under medical supervision.

For violations of liver function

• severe liver failure: taking Azithromycin Forte-OBL is contraindicated;
• liver dysfunction in a moderate course: therapy should be carried out under medical supervision.

Drug interactions

• cycloserine, indirect anticoagulants, methylprednisolone, felodipine, drugs that undergo microsomal oxidation (including hexobarbital, carbamazepine, cyclosporine, phenytoin, terfenadine, ergot alkaloids, valproic acid, bromocriptine, peroxidase, and hyporamine); their elimination and increase in plasma concentration and toxicity;
• antacids (containing aluminum and magnesium), food and ethanol: when used together, the absorption of azithromycin slows down and decreases, so it must be taken 1 hour before or 2 hours after taking them;
• cyclosporine: if necessary, simultaneous use, it is necessary to monitor the concentration of cyclosporine in the blood and adjust its dose;
• warfarin: the likelihood of an increase in the anticoagulant effect must be taken into account, careful monitoring of prothrombin time and INR (international normalized ratio) is required;
• digoxin: combined use leads to an increase in its concentration;
• ergotamine and dihydroergotamine: there is an increase in toxic effects, therefore, the simultaneous use of these drugs with azithromycin is contraindicated;
• triazolam: with combined therapy, its clearance decreases and the pharmacological effect increases;
• tetracycline and chloramphenicol: the effect of azithromycin therapy is enhanced;
• lincosamines: the effect of azithromycin therapy is weakened;
• rifabutin: against the background of combined use, the development of neutropenia is possible.
