In case of renal dysfunction: when used in patients with mild to moderate renal dysfunction (creatinine clearance more than 40 ml/min), no dose adjustment is required.

For liver dysfunction: When used in patients with mild to moderate liver dysfunction, no dose adjustment is required.

Elderly patients: no dose adjustment is required. Since elderly people may already have current proarrhythmogenic conditions, caution should be exercised when using the drug Sumamed® due to the high risk of developing cardiac arrhythmias, including arrhythmias.

Pharmacodynamics

Has a wide spectrum of antimicrobial action. By binding to the 50S ribosomal subunit, it inhibits the biosynthesis of microorganism proteins. In high concentrations it has a bactericidal effect. It is active against gram-positive, gram-negative anaerobes, intracellular and other microorganisms.

Has no effect on gram-positive bacteria resistant to erythromycin.

Pharmacokinetics

When taken orally, azithromycin is well absorbed and quickly redistributed from plasma to tissues and organs. After a single oral dose of 500 mg of azithromycin, 37% of the drug is absorbed and after 2-3 hours the Cmax of the drug is 0.41 mcg/ml in the plasma. It is known that food intake can reduce the absorption of azithromycin, however, due to the insufficiency of the manufacturer's own data on the effect of food on the pharmacokinetics of azithromycin when taking Sumamed® in the form of a suspension, it should be taken at least 1 hour before or after 2 h after eating.

The drug is rapidly distributed throughout the body, high concentrations, 50 times higher than the concentration of azithromycin in plasma, are observed in tissues. Depending on the organ/tissue, the drug concentration ranges from 1-9 mcg/ml. The volume of distribution averages 31 l/kg.

The therapeutic concentration of azithromycin in tissues is observed within 5-7 days after taking the last dose. Penetrates into cells, including phagocytes, which migrate to the site of inflammation, helping to create therapeutic concentrations of the drug that exceed the MIC for infectious agents. Concentrations of azithromycin in infected tissues are higher compared to uninfected tissues. It has a long T1/2 and is slowly eliminated from tissues (on average 2-4 days).

Excretion of azithromycin into bile is the main route of elimination. On average, up to 50% is excreted in bile in unchanged form. The remaining 50% is excreted in the form of 10 metabolites formed during the process of N- and O-demethylation, hydroxylation of desosamine and aglycone ring and as a result of cleavage of the cladinose conjugate. Metabolites do not have antibacterial activity. An average of 6% of the administered dose of the drug is excreted in the urine.

In elderly patients (over 65 years of age), the volume of distribution is slightly higher (30%) compared to patients under 45 years of age, which is not clinically significant and does not require dosage changes.

The pharmacokinetics of azithromycin in healthy volunteers after a single intravenous infusion lasting more than 2 hours at a dose of 1000-4000 mg (solution concentration 1 mg/ml) has a linear relationship and is proportional to the administered dose. T1/2 of the drug is 65-72 hours. The high level of observed volume of distribution (33.3 l/kg) and plasma clearance (10.2 ml/min/kg) suggests that the long T1/2 of the drug is a consequence of the accumulation of the antibiotic in tissues followed by its slow release.

In healthy volunteers, with an intravenous infusion of azithromycin at a dose of 500 mg (solution concentration 1 mg/ml) for 3 hours, the Cmax of the drug in the blood serum was 1.14 μg/ml. The minimum serum level (0.18 μg/ml) was observed over 24 hours and the area under the concentration-time curve was 8.03 μg/ml/h.

Similar pharmacokinetic values ​​were obtained in patients with community-acquired pneumonia who were prescribed intravenous infusions (3 hours) for 2 to 5 days. After daily administration of azithromycin at a dose of 500 mg (infusion duration - 1 hour) for 5 days, an average of 14% of the dose is excreted in the urine over a 24-hour dosing interval.

Indications for use Sumamed 125 mg 6 pcs. film-coated tablets

  • infections of the upper respiratory tract and ENT organs;
  • lower respiratory tract infections: acute bronchitis, exacerbation of chronic bronchitis, pneumonia, incl. caused by atypical pathogens;;

  • genitourinary tract infections (urethritis, cervicitis).

Contraindications

  • severe dysfunction of the liver and kidneys;
  • lactation period;
  • simultaneous use with ergotamine and dihydroergotamine;
  • hypersensitivity to azithromycin and other components of the drug;
  • increased sensitivity to macrolide antibiotics;
  • children under 12 years of age and body weight less than 45 kg (for capsules and tablets 500 mg);
  • children under 3 years of age (for tablets 125 mg).

Sumamed should be prescribed with caution in cases of moderate impairment of liver and kidney function, in patients with disorders or predisposition to arrhythmias and prolongation of the QT interval.

Application Sumamed 125 mg 6 pcs. film-coated tablets during pregnancy and breastfeeding

During pregnancy, the use of sumamed is possible only if the potential benefit of therapy for the mother outweighs the possible risk to the fetus.

If it is necessary to use sumamed during lactation, breastfeeding should be stopped

special instructions

When using the drug Sumamed® in patients with diabetes mellitus, as well as on a low-calorie diet, it is necessary to take into account that the suspension contains sucrose (0.32 XE/5 ml).

If you miss one dose of Sumamed®, the missed dose should be taken as soon as possible, and subsequent doses should be taken at intervals of 24 hours. Sumamed® should be taken at least one hour before or two hours after taking antacids.

The drug Sumamed® should be taken with caution in patients with mild to moderate liver dysfunction due to the possibility of developing fulminant hepatitis and severe liver failure.

If there are symptoms of liver dysfunction, such as rapidly increasing asthenia, jaundice, darkening of urine, tendency to bleeding, hepatic encephalopathy, therapy with Sumamed® should be stopped and a study of the functional state of the liver should be performed.

In case of mild to moderate renal dysfunction (creatinine clearance more than 40 ml/min), therapy with Sumamed® should be carried out with caution under monitoring the state of renal function.

As with the use of other antibacterial drugs, during therapy with Sumamed®, patients should be regularly examined for the presence of non-responsive microorganisms and signs of the development of superinfections, including fungal ones. The drug Sumamed® should not be used in longer courses than indicated in the instructions, since the pharmacokinetic properties of azithromycin allow us to recommend a short and simple dosage regimen.

There is no data on a possible interaction between azithromycin and ergotamine and dihydroergotamine derivatives, but due to the development of ergotism with the simultaneous use of macrolides with ergotamine and dihydroergotamine derivatives, this combination is not recommended.

With long-term use of the drug Sumamed®, the development of pseudomembranous colitis caused by Clostridium difficile, both in the form of mild diarrhea and severe colitis, is possible. If antibiotic-associated diarrhea develops while taking Sumamed®, as well as 2 months after the end of therapy, clostridial pseudomembranous colitis should be excluded.

When treated with macrolides, including azithromycin, prolongation of cardiac repolarization and QT interval was observed, increasing the risk of developing cardiac arrhythmias, including arrhythmias, which can lead to cardiac arrest.

Caution should be exercised when using the drug Sumamed® in patients with the presence of proarrhythmogenic factors (especially in elderly patients), including congenital or acquired prolongation of the QT interval; in patients taking antiarrhythmic drugs of classes IA (quinidine, procainamide), III (dofetilide, amiodarone and sotalol), cisapride, terfenadine, antipsychotic drugs (pimozide), antidepressants (citalopram), fluoroquinolones (moxifloxacin and levofloxacin), with fluid and electrolyte disorders balance, especially in the case of hypokalemia or hypomagnesemia, clinically significant bradycardia, cardiac arrhythmia or severe heart failure.

The use of Sumamed® may provoke the development of myasthenic syndrome or cause an exacerbation of myasthenia.

Impact on the ability to drive vehicles and operate machinery

If undesirable effects on the nervous system and organ of vision develop, caution should be exercised when performing actions that require increased concentration and speed of psychomotor reactions.

Overdose

Symptoms: nausea, temporary hearing loss, vomiting, diarrhea.

Treatment: gastric lavage, symptomatic therapy.

Side effects Sumamed 125 mg 6 pcs. film-coated tablets

From the hematopoietic system: rarely - thrombocytopenia, neutropenia, eosinophilia.

From the central nervous system and peripheral nervous system: sometimes - dizziness/vertigo, headache, drowsiness, convulsions; rarely - paresthesia, asthenia, insomnia, hyperactivity, aggressiveness, anxiety, nervousness.

From the digestive system: often - nausea, vomiting, diarrhea, abdominal pain and cramps; sometimes - diarrhea, flatulence, digestive disorders, anorexia; rarely - constipation, discoloration of the tongue, pseudomembranous colitis, cholestatic jaundice, hepatitis, changes in laboratory parameters of liver function; very rarely - liver dysfunction and liver necrosis (possibly fatal).

Allergic reactions: sometimes - itching, skin rashes; rarely - angioedema, urticaria, photosensitivity, anaphylactic reaction, erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis.

Drug interactions

Sumamed® (capsules, film-coated tablets, powder for oral suspension)

Antacids (containing aluminum, magnesium, ethanol) and food intake significantly reduce the absorption of azithromycin (capsules and suspension), so the drug should be taken at least 1 hour before or 2 hours after taking these drugs and food. It does not bind to the enzymes of the cytochrome P-450 complex and, unlike macrolide antibiotics, to date there has been no interaction with theophylline, terfenadine, carbamazepine, methylprednisolone, cimetidine, triazolam, digoxin. Macrolides, when taken simultaneously with cycloserine, indirect anticoagulants, methylprednisolone, felodipine and drugs subject to microsomal oxidation (cyclosporine, hexobarbital, ergot alkaloids, valproic acid, disopyramide, bromocriptine, phenytoin, oral hypoglycemic agents) slow down the elimination, increase the concentration and toxicity of these drugs, while with the use of azalides such an interaction has not been observed to date.

If it is necessary to take it together with warfarin, it is recommended to carefully monitor the PT (there may be an increase in PT and the incidence of hemorrhages). When macrolides are taken simultaneously with ergotamine and dihydroergotamine, their toxic effects (vasospasm, dysesthesia) may occur. Lincosamides weaken, and tetracycline and chloramphenicol enhance the effectiveness of azithromycin. Pharmaceutically incompatible with heparin.

Sumamed® (lyophilisate for the preparation of solution for infusion)

Although there is no data on interactions between azithromycin and ergot alkaloids, caution must be exercised as simultaneous administration can lead to an increase in the concentration of alkaloids in the blood and to the development of overdose symptoms (ergotism), which is observed when alkaloids are taken together with macrolides; Antibiotics of the macrolide group increase the blood concentration of theophylline, terfenadine, warfarin, carbamazepine, phenytoin, digoxin, cyclosporine, ergotamine, triazolam and midazolam, thereby enhancing their effect. Unlike macrolides, azithromycin does not inhibit cytochrome P450, therefore, when it is prescribed with the above drugs, similar interactions are not observed.
