Instructions for use SUMAMOX

Suction

After taking the drug orally, azithromycin is quickly absorbed from the gastrointestinal tract, which is due to its stability in an acidic environment and lipophilicity. After oral administration of 500 mg of azithromycin, Cmax in blood plasma is reached after 2.5-2.96 hours and is 0.4 mg/l. The bioavailability of the drug is 37%.

Eating food and alcohol reduces the speed and completeness of absorption. When using the drug shortly after a meal, Cmax in the blood decreases by approximately 50%.

Distribution

Azithromycin easily passes through histohematic barriers and enters tissues; it penetrates well into the respiratory tract, organs and tissues of the urogenital tract (in particular, the prostate gland), skin and soft tissues. Penetrates through cell membranes (effective against infections caused by intracellular pathogens).

Stable plasma levels are achieved after 5-7 days. High concentration in tissues (10-50 times higher than in blood plasma) and long T1/2 are due to low binding of azithromycin to plasma proteins (7-50% inversely proportional to blood concentration), as well as its ability to penetrate eukaryotic cells and concentrate in the low pH environment surrounding the lysosomes. This, in turn, determines the large apparent Vd (31.1 l/kg) and high plasma clearance.

The ability of azithromycin to accumulate predominantly in lysosomes is especially important for the elimination of intracellular pathogens. It has been proven that azithromycin is also transported by phagocytes, polymorphonuclear leukocytes and macrophages to the site of infection, where it is released in the presence of bacteria during the process of phagocytosis. The concentration of azithromycin in foci of infection is significantly higher than in healthy tissues (on average by 24-34%) and correlates with the severity of inflammatory edema.

Despite its high concentration in phagocytes, azithromycin does not have a significant effect on their function. Preservation of azithromycin in bactericidal concentrations at the site of inflammation for 5-7 days after taking the last dose allowed the development of short (3-day and 5-day) courses of treatment.

Metabolism and excretion

A small amount of the drug is metabolized in the liver. The resulting metabolites are inactive.

The removal of azithromycin from blood plasma occurs in two stages:

T1/2 is 14-20 hours in the interval from 8 to 24 hours after taking the drug and 41 hours in the interval from 24 to 72 hours, which allows the drug to be used once a day.

About 50% of the administered dose of azithromycin is excreted in the bile unchanged and in the form of metabolites in the bile, about 6% in the urine.

Pharmacokinetics in special clinical situations

In elderly (65-85 years old) male patients, the pharmacokinetic parameters do not change; in female patients, Cmax in blood plasma increases by 30-50%.

In patients aged 1 to 5 years, Cmax in the blood and T1/2 are reduced compared to those in adult patients.

Pharmacological properties

Pharmacokinetics

Suction

After oral administration, azithromycin is rapidly absorbed. The binding of azithromycin to plasma proteins varies depending on the concentration and decreases from 51% at 0.02 μg/ml to 7% at 2 μg/ml.

Distribution

Azithromycin is widely distributed throughout the body. The rapid distribution of azithromycin in tissues and high intracellular concentrations provide higher concentrations of the drug in tissues than in plasma or serum.

Metabolism and excretion

Azithromycin is eliminated from blood plasma in 2 stages: the half-life (T1/2) is 14-20 hours in the range from 8 hours to 24 hours after taking the drug and 41 hours in the range from 24 hours to 72 hours, which allows the use of the drug 1 time/day The drug is excreted mainly in bile unchanged, a small part is excreted by the kidneys.

Pharmacodynamics

The active substance of the drug Sumamox - azithromycin - is a broad-spectrum antibiotic, the first representative of a new subgroup of macrolide antibiotics - azalides.

Drug interactions

Sumamox affects the activity of enzymes of the cytochrome P-450 complex and, unlike other macrolides, there is currently no interaction with theophylline, carbamazepine, or triazolam.

When warfarin and azithromycin were co-administered (in usual doses), no change in prothrombin time was detected, however, given that the interaction of macrolides and warfarin may enhance the anticoagulant effect, patients need careful monitoring of prothrombin time.

Ergotamine and dihydroergotamine: increased toxic effects (vasospasm, dysesthesia).

Antacids

When studying the pharmacokinetics of the combined use of an antacid with azithromycin, no overall change in bioavailability was observed, although when measuring the maximum plasma concentration of azithromycin, a decrease in concentration by 25% was observed. Sumamox should be taken at least 1 hour before or 2 hours after antacids.

Cetirizine

In healthy volunteers, co-administration of azithromycin with cetirizine 20 mg did not result in pharmacokinetic interactions and no significant changes in the QT interval.

Digoxin

In some patients, the use of macrolides with digoxin led to disruption of the metabolism of digoxin in the intestine. Therefore, the combined use of azithromycin and digoxin may lead to an increase in digoxin concentrations by reducing its inactivation by intestinal flora.

Zidovudine

1000 mg and 1200 mg single doses or 600 mg multiple doses of azithromycin have little effect on the pharmacokinetics of zidovudine or its glucuronide metabolite in plasma or urinary excretion.

Didanosine (dideoxyinosine)

The combined use of azithromycin and didanosine does not affect the pharmacokinetics of didanosine.

Cyclosporine

When azithromycin and cyclosporine are used together, an increase in the concentration of cyclosporine and PPFK-5 is observed. If co-administration is necessary, dose adjustment of cyclosporine is necessary.

Nelfinavir

When azithromycin and nelfinavir are used together, an increase in the concentration of nelfinavir is observed. No clinically significant side effects were observed and no dose adjustment is required.

Cisapride

Cisapride is metabolized in the liver by the enzyme CYP3A4. Macrolides inhibit this enzyme, so coadministration of cisapride and azithromycin may cause QT prolongation, ventricular arrhythmia, and torsade de pointes (TdP).

Substances that prolong the QT interval

Azithromycin should not be used in combination with other active substances that prolong the QT interval.

special instructions

Elderly patients and patients with heart disease may be more susceptible to the arrhythmogenic effects of the antibiotic.

If signs of hepatitis appear, Sumamox should be discontinued immediately.

If allergic reactions occur, Sumamox should be discontinued immediately and appropriate therapy should be initiated. Sumamox is prescribed with caution to patients with cardiovascular pathology. High-risk patients with a history of prolonged QT interval, hypokalemia, hypomagnesemia and bradycardia should be carefully consulted by a physician.

Sumamox contains sucrose. The sucrose content should be taken into account in patients with diabetes mellitus.

Allergic reactions

In rare cases, azithromycin may cause serious allergic reactions such as angioedema and anaphylaxis.

Kidney failure

In patients with mild to moderate renal impairment (GFR 10 -80 ml/min), dose adjustment is not necessary. Caution is recommended when administered to patients with severe renal impairment (GFR <10 ml/min).

Liver failure

Because the liver is the primary route of elimination of azithromycin, use of Sumamox should be used with caution in patients with significant liver disease. If signs and symptoms of liver dysfunction appear, such as rapid development of asthenia associated with jaundice, dark urine, bleeding tendency, or hepatic encephalopathy, laboratory tests of liver function should be performed immediately. If liver dysfunction occurs, azithromycin should be discontinued immediately.

It should be taken into account before prescribing Sumamox : Sumamox in suspension for oral use is not suitable for the treatment of severe infections where a rapid increase in the concentration of the antibiotic in the blood is necessary. When prescribing azithromycin and other antibiotics, it is important to take into account diseases caused by pathogens resistant to erythromycin. As for other macrolides, high levels of resistance to Streptococcus pneumoniae (> 30%) have been obtained for azithromycin. This should be taken into account when treating infections caused by Streptococcus pneumoniae.

The main causative agent of soft tissue infections, Staphylococcus aureus, is often resistant to azithromycin. Therefore, azithromycin sensitivity testing is considered a prerequisite for the treatment of soft tissue infections.

Pharyngitis/tonsillitis

Sumamox is not the first choice substance for the treatment of pharyngitis and tonsillitis caused by Streptococcus pneumoniae. For this and for the prevention of acute rheumatic fever, penicillin is the first drug of choice.

Sinusitis

Sumamox is not the first choice substance for the treatment of sinusitis and acute otitis media.

Superinfections

Attention should be paid to possible symptoms of superinfection caused by insensitive pathogens such as fungi. Superinfection may require discontinuation of azithromycin treatment and appropriate measures are taken.

Neurological or psychiatric diseases

Sumamox should be prescribed with caution to patients suffering from neurological or psychiatric diseases.

Myasthenia gravis

There have been cases of myasthenia gravis symptoms and exacerbation of myasthenia gravis symptoms in patients receiving azithromycin.

Diarrhea associated with Clostridium difficile

Clostridium difficile associated diarrhea (CAD) occurs in almost all cases of use of antibacterial agents, including Sumamox, and can vary in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon and leads to overgrowth of Clostridium difficile

Long-term use

The safety and effectiveness of long-term use of azithromycin for these indications is not known. In cases of rapid recurrent infection, treatment with other antibiotics should be considered. The safety of azithromycin in children under 6 months of age has not been established. The safety and effectiveness of azithromycin for the prevention or treatment of Yellow Bacillus Complex (YBC) in children has not been established.

Sumamox 500 mg No. 3 tablet p.o.

Sumamox Trade name Sumamox International nonproprietary name Azithromycin Dosage form Film-coated tablets 500 mg Composition One tablet contains the active substance - azithromycin dihydrate (equivalent to azithromycin base) 500.00 mg, excipients: starch, starch paste, calcium phosphate, talc, magnesium stearate, sodium starch glycolate, sodium crosscarmellose, polyvinylpyrrolidone K-30, shell composition: white tabcoate, hydroxypropyl methylcellulose, polyethylene glycol, talc, titanium dioxide. Description Tablets, coated, white or almost white, capsule-shaped (caplets), with a break line on both sides. At the break there is a white or almost white tablet core. Pharmacotherapeutic group Systemic antibacterial drugs, Macrolides ATC code J01FA10 Pharmacological action Pharmacokinetics After oral administration, Azithromycin is well absorbed and quickly distributed in the body. After a single dose of 500 mg, bioavailability is 37% (the “first pass” effect), the maximum concentration (0.4 mg/l) in the blood is created after 2 - 3 hours, the apparent volume of distribution is 31.1 l/kg, protein binding is inversely proportional to the concentration in the blood and ranges from 7 to 50%. Penetrates through cell membranes (effective against infections caused by intracellular pathogens). Transported by phagocytes to the site of infection, where it is released in the presence of bacteria. Easily passes histohematic barriers and enters tissues. The concentration in tissues and cells is 10–50 times higher than in plasma, and at the site of infection it is 24–34% higher than in healthy tissues. The elimination of azithromycin from blood plasma occurs in 2 stages: the half-life is 14-20 hours in the range from 8 to 24 hours after taking the drug and 41 hours in the range from 24 to 72 hours, which allows the drug to be used once a day. The half-life from tissues is significantly longer. The therapeutic concentration of azithromycin lasts up to 5 to 7 days after taking the last dose. Azithromycin is excreted mainly unchanged - 50% by the intestines, 6% by the kidneys. In the liver it is demethylated, losing activity. Pharmacodynamics Sumamox is a broad-spectrum bacteriostatic antibiotic from the group of macrolides - azalides. Has a wide spectrum of antimicrobial action. The mechanism of action of Sumamox is associated with the suppression of protein synthesis in microbial cells. By binding to the 5OS subunit of the ribosome, it inhibits peptide translocase at the translation stage and suppresses protein synthesis, slowing down the growth and reproduction of bacteria. In high concentrations it has a bactericidal effect. Sumamox has activity against a number of gram-positive, gram-negative, anaerobes, intracellular and other microorganisms. Microorganisms may be initially resistant to the action of Sumamox or may acquire resistance to it. In most cases, sensitive microorganisms 1. Gram-positive aerobes Staphylococcus aureus Methicillin - sensitive Streptococcus pneumoniae Penicillin - sensitive Streptococcus pyogenes 2. Gram-negative aerobes Haemophilus influenzae Haemophilus parainfluenzae Legionlla pneumophila Moraxella catarrhalis Pasteurella multocida Neisseria gonorrhoeae 3.

Rarely - thrombocytopenia, neutropenia - paresthesia, asthenia, insomnia, hyperactivity, aggressiveness, anxiety, nervousness - tinnitus, reversible hearing loss up to deafness (when taking high doses for a long time), impaired perception of taste and smell - palpitations, arrhythmia , ventricular tachycardia, increased QT interval, bidirectional ventricular tachycardia - constipation, tongue discoloration, pseudomembranous colitis, cholestatic jaundice, hepatitis, changes in laboratory tests of liver function - angioedema, urticaria, photosensitivity, anaphylactic reaction, including edema (in rare cases fatal outcome), erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis - nephritis, acute renal failure - vaginitis, candidiasis Very rare - liver failure, liver necrosis (possibly fatal) Contraindications - hypersensitivity to macrolide antibiotics - severe dysfunction liver and kidneys - pregnancy and lactation - children under 16 years of age Drug interactions Antacids (containing aluminum, magnesium) and food intake significantly reduce the absorption of azithromycin, so the drug should be taken 1 hour before or 2 hours after meals and antacids. It does not affect the activity of enzymes of the cytochrome P-450 complex and, unlike other macrolides, there is currently no interaction with theophylline, carbamazepine, triazolam. When warfarin and azithromycin were co-administered (in usual doses), no change in prothrombin time was detected, however, given that the interaction of macrolides and warfarin may enhance the anticoagulant effect, patients need careful monitoring of prothrombin time. Increases the concentration of digoxin by reducing its inactivation by intestinal flora. Ergotamine and dihydroergotamine: increased toxic effects (vasospasm, dysesthesia). Special instructions It is necessary to observe a break of 2 hours while using antacids. Use in pediatrics The safety of prescribing Sumamox in children and adolescents under 16 years of age has not been fully established. Features of the effect of the drug on the ability to drive a vehicle or potentially dangerous mechanisms Considering the possibility of developing side effects from the central nervous system, caution should be exercised.
