Bacteriostatic antibiotic of macrolide-azalide group.

• It has a wide spectrum of antimicrobial action.
• The mechanism of action of azithromycin is associated with the suppression of protein synthesis of a microbial cell. By binding to the 50S subunit of the ribosome, it inhibits the peptidranslokase at the translation stage and suppresses protein synthesis, slowing the growth and multiplication of bacteria. In high concentrations has a bactericidal effect.
• It has activity against a number of gram-positive, gram-negative, anaerobes, intracellular and other microorganisms.
• Microorganisms may initially be resistant to the action of the antibiotic or may acquire resistance to it.

The sensitivity scale of microorganisms to azithromycin (MIC, mg / L)

	MIC, mg / L	MIC, mg / L
Microorganisms	sensitive	resistant
Staphylococcus	≤1	>2
Streptococcus A, B, C, G	≤0,25	>0,5
Streptococcus pneumonia	≤0,25	>0,5
Haemophilus influenzae	≤0,12	>4
Moraxella catarrhalis	≤0,5	>0,5
Neisseria gonorrhoeae	≤0,25	>0,5

 

In most cases, the drug Sumamed is active against aerobic Gram-positive bacteria:

• Staphylococcus aureus (methicillin-sensitive strains), Streptococcus pneumoniae (penicillin-sensitive strains), Streptococcus pyogenes;
• aerobic gram-negative bacteria: Haemophilus influenzae, Haemophilus parainfluenzae, Legionella pneumophila, Moraxella catarrhalis, Pasteurella multocida, Neisseria gonorrhoeae;
• anaerobic bacteria: Clostridium perfringens, Fusobacterium spp., Prevotella spp., Porphyromonas spp .;
• other microorganisms: Chlamydia trachomatis, Chlamydia pneumoniae, Chlamydia psittaci, Mycoplasma pneumoniae, Mycoplasma hominis, Borrelia burgdorferi.

Microorganisms that can develop resistance to azithromycin:

• gram-positive aerobes - Streptococcus pneumoniae (penicillin-resistant strains).
• Initially, stable microorganisms: gram-positive aerobes - Enterococcus faecalis, Staphylococci (methicillin-resistant strains of staphylococcus exhibit a very high degree of resistance to macrolides);
• Gram-positive bacteria resistant to erythromycin; anaerobes - Bacteroides fragilis.

Suction

 

After oral administration, azithromycin is well absorbed and quickly distributed in the body. After a single dose of 500 mg, bioavailability is 37% due to the "first pass" effect through the liver. Cmax in blood plasma is achieved after 2-3 hours and is 0.4 mg / l.

 

Distribution

 

Binding to proteins is inversely proportional to the concentration in the blood plasma and is 7-50%. The apparent Vd is 31.1 l / kg. Penetrates through cell membranes (effective for infections caused by intracellular pathogens). It is transported by phagocytes to the site of infection, where it is released in the presence of bacteria. Easily penetrates through the histohematological barriers and enters the tissues. Concentration in tissues and cells is 10-50 times higher than in plasma, and in the focus of infection - 24-34% more than in healthy tissues.

 

Metabolism

 

In the liver, demethylated, losing activity.

 

Excretion

 

T1 / 2 is very long - 35-50 h. T1 / 2 of the tissues is much larger. The therapeutic concentration of azithromycin is maintained up to 5-7 days after the last dose. Azithromycin is excreted, basically, in unchanged form - 50% through the intestine, 6% by the kidneys.

Symptoms:

 

• nausea,
• temporary loss of hearing,
• vomiting,
• diarrhea.

 

Treatment:

 

• symptomatic therapy.

• Antacid preparations

Antacids do not affect the bioavailability of azithromycin, but reduce Cmax in the blood by 30%, so Sumamed should be taken at least 1 hour before or 2 hours after taking these drugs and food.

• Cetirizine

Simultaneous use of azithromycin with cetirizine (20 mg) for 5 days in healthy volunteers did not lead to pharmacokinetic interaction and a significant change in the QT interval.

• Didanosine (dideoxyinosine)

The simultaneous use of azithromycin (1200 mg / day) and didanosine (400 mg / day) in 6 HIV-infected patients showed no change in the pharmacokinetic indices of didanosine compared with the placebo group.

• Digoxin (substrates of P-glycoprotein)

Simultaneous use of macrolide antibiotics, incl. azithromycin, with substrates of the P-glycoprotein, such as digoxin, leads to an increase in the concentration of the P-glycoprotein substrate in the serum. Thus, with the simultaneous use of azithromycin and digoxin, it is necessary to take into account the possibility of increasing the concentration of digoxin in the blood serum.

• Zidovudine

Simultaneous use of azithromycin (a single dose of 1000 mg and repeated administration of 1200 mg or 600 mg) has a negligible effect on the pharmacokinetics, incl. kidney removal of zidovudine or its glucuronide metabolite. However, the use of azithromycin caused an increase in the concentration of phosphorylated zidovudine, a clinically active metabolite in peripheral blood mononuclear cells. The clinical significance of this fact is unclear.

Azithromycin weakly interacts with isoenzymes of the cytochrome P450 system. It was not revealed that azithromycin is involved in the pharmacokinetic interaction with the analogous erythromycin and other macrolides. Azithromycin is not an inhibitor and inducer of cytochrome P450 isoenzymes.

• Alkaloids of ergot

Given the theoretical possibility of the emergence of ergotism, the simultaneous use of azithromycin with derivatives of ergot alkaloids is not recommended.

Pharmacokinetic studies of the simultaneous use of azithromycin and drugs whose metabolism occurs with the participation of cytochrome P450 isoenzymes have been carried out.

• Atorvastatin

The simultaneous use of atorvastatin (10 mg daily) and azithromycin (500 mg daily) did not cause a change in the concentrations of atorvastatin in the blood plasma (based on the inhibition of GMA-CoA reductase). However, in the post-marketing period, separate reports were received on cases of rhabdomyolysis in patients receiving both azithromycin and statins.

• Carbamazepine

In pharmacokinetic studies involving healthy volunteers, there was no significant effect on the concentration of carbamazepine and its active metabolite in blood plasma in patients treated with azithromycin simultaneously.

• Cimetidine

In pharmacokinetic studies of the effect of cimetidine on single-dose administration of azithromycin pharmacokinetics, there was no change in the pharmacokinetics of azithromycin, provided cimetidine was administered 2 hours before azithromycin.

• Anticoagulants of indirect action (coumarin derivatives)

In pharmacokinetic studies, azithromycin did not affect the anticoagulant effect of warfarin when administered in a single dose of 15 mg by healthy volunteers. Potential anticoagulant effect was reported after simultaneous use of azithromycin and indirect anticoagulants (coumarin derivatives). Although a causal relationship has not been established, consideration should be given to the need for frequent monitoring of prothrombin time when azithromycin is used in patients who receive oral anticoagulants of indirect action (coumarin derivatives).

• Cyclosporin

In a pharmacokinetic study involving healthy volunteers who within 3 days were ingested azithromycin (500 mg / day once) and then cyclosporine (10 mg / kg / day once), there was a significant increase in Cmax in the blood plasma and AUC0-5 cyclosporine . Care should be taken when using these drugs at the same time. In case of simultaneous use of these drugs, the concentration of cyclosporin in the blood plasma should be monitored and, accordingly, the dose should be adjusted.

• Efavirenz

Simultaneous use of azithromycin (600 mg / day once) and efavirenz (400 mg / day) daily for 7 days did not cause any clinically significant pharmacokinetic interaction.

• Fluconazole

Simultaneous use of azithromycin (1200 mg once) did not change the pharmacokinetics of fluconazole (800 mg once). The total exposure and T1 / 2 azithromycin did not change with the simultaneous use of fluconazole, but a decrease in Cmax of azithromycin (by 18%) was observed, which was not clinically significant.

• Indinavir

Simultaneous use of azithromycin (1200 mg once) did not cause a statistically significant effect on the pharmacokinetics of indinavir (800 mg 3 times / day for 5 days).

• Methylprednisolone

Azithromycin does not significantly affect the pharmacokinetics of methylprednisolone.

• Nelfinavir

Simultaneous use of azithromycin (1200 mg) and nelfinavir (750 mg 3 times / day) causes an increase in Css azithromycin in blood plasma. Clinically significant side effects were not observed and correction of the dose of azithromycin with its simultaneous application with nelfinavir is not required.

• Rifabutin

Simultaneous use of azithromycin and rifabutin does not affect the concentration of each drug in the blood plasma. With the simultaneous use of azithromycin and rifabutin, neutropenia was sometimes observed. Despite the fact that neutropenia was associated with the use of rifabutin, a causal relationship between the use of a combination of azithromycin and rifabutin and neutropenia has not been established.

• Sildenafil

When used in healthy volunteers, evidence of the effect of azithromycin (500 mg / day daily for 3 days) on AUC and Cmax sildenafil or its main circulating metabolite was not obtained.

• Terfenadine

In pharmacokinetic studies, there was no evidence of interaction between azithromycin and terfenadine. Individual cases were reported where the possibility of such interaction could not be ruled out completely, but there was not one concrete proof that such an interaction took place. It was found that simultaneous use of terfenadine and macrolides can cause arrhythmia and lengthening of the QT interval.

• Theophylline

There was no interaction between azithromycin and theophylline.

• Triazolam / midazolam

Significant changes in pharmacokinetic parameters with the simultaneous use of azithromycin with triazolam or midazolam in therapeutic doses have not been revealed.

• Trimethoprim / sulfamethoxazole

With the simultaneous use of trimethoprim / sulfamethoxazole with azithromycin, there is no significant effect on Cmax, total exposure or excretion of trimethoprim or sulfamethoxazole by the kidneys. The concentrations of azithromycin in the serum corresponded to those detected in other studies.

• If you miss one dose of the drug - the missed dose should be taken as soon as possible, and the next - with interruptions of 24 hours.
• Sumamed should be taken at least 1 hour before or 2 hours after taking antacid preparations.
• Sumamed should be used with caution in patients with mild to moderate liver function disorders due to the possibility of developing fulminant hepatitis and severe hepatic insufficiency. If there are signs of liver dysfunction, such as rapidly growing asthenia, jaundice, darkening of the urine, a tendency to bleeding, hepatic encephalopathy with Sumamed should be stopped and a study of the functional state of the liver.
• If the renal function is impaired in patients with GFR 10-80 ml / min dose adjustment is not required, therapy with Sumamed should be performed with caution under the control of the state of kidney function.
• As with the use of other antibacterial drugs, when treating with Sumamed, patients should be regularly monitored for the presence of non-susceptible microorganisms and signs of development of superinfections, incl. fungal.
• Sumamed should not be used for longer courses than indicated in the instructions. pharmacokinetic properties of azithromycin allow us to recommend a short and simple dosing regimen.
• There is no data on the possible interaction between azithromycin and derivatives of ergotamine and dihydroergotamine, but because of the development of ergotism with the simultaneous use of macrolides with derivatives of ergotamine and dihydroergotamine, this combination is not recommended.
• With long-term administration of Sumamed drug, it is possible to develop pseudomembranous colitis caused by Clostridium difficile, both in the form of mild diarrhea and severe colitis. With the development of antibiotic-associated diarrhea against the background of taking the drug Sumamed, and also 2 months after the end of therapy, clostridial pseudomembranous colitis should be excluded. Do not use drugs that inhibit the intestinal peristalsis.
• When treating macrolides, incl. azithromycin, there was an increase in cardiac repolarization and QT interval, which increased the risk of cardiac arrhythmias, incl. arrhythmias of the "pirouette" type.
• Caution should be used when using Sumamed in patients with proarrhythmogenic factors (especially in elderly patients), incl. with congenital or acquired lengthening of the QT interval; in patients,
• (dopetilide, amiodarone and sotalol), cisapride, terfenadine, antipsychotics (pimozide), antidepressants (citalopram), fluoroquinolones (moxifloxacin and levofloxacin), in patients with disturbances of the water-electrolyte balance , especially in the case of hypokalemia or hypomagnesemia, clinically significant bradycardia, cardiac arrhythmia or severe heart failure.
• The use of the Sumamed drug can provoke the development of myasthenic syndrome or cause an exacerbation of myasthenia gravis.
• When used in patients with diabetes mellitus, as well as in patients who observe a low-calorie diet, it must be taken into account that sucrose (0.32 XE / 5 ml) is included as an auxiliary substance in the powder for the suspension of Sumamed.
• Impact on the ability to drive vehicles and manage mechanisms
• With the development of undesirable effects from the nervous system and the organ of vision, care should be taken when performing actions requiring increased concentration of attention and speed of psychomotor reactions.

During pregnancy and during breastfeeding, the drug can be used only if the expected potential benefit of therapy for the mother exceeds the potential risk to the fetus and the baby.

If it is necessary to use the drug during lactation, breastfeeding should be stopped.

• Contraindicated:

children under 12 years of age and body weight less than 45 kg (for capsules and tablets 500 mg); children's age to 3 years (for tablets 125 mg, children's age to 6 months (for powder for the preparation of suspension).

In severe renal impairment (CC <40 ml / min), the drug is contraindicated. Caution should be given to the drug for mild to moderate renal dysfunction.

In severe violations of the liver (class C on the scale Child-Pugh) drug is contraindicated. Caution should be given for mild to moderate liver function abnormalities.

In elderly patients, dose adjustment of Sumamed is not required. Since this category of patients may have pro-arrhythmic conditions, Sumamed should be used with caution in connection with the high risk of arrhythmias, incl. ventricular arrhythmia of the "pirouette" type.

The drug should be stored out of the reach of children at a temperature of no higher than 25 ° C. Shelf life of the drug in the form of capsules and tablets, coated with a coating - 3 years, powder for the preparation of a suspension for oral administration - 2 years, the prepared suspension - 5 days.
