Amoxiclav^®

For powder for preparation of solution for intravenous administration in addition

abdominal infections,

sexually transmitted infections (gonorrhea, mild chancre),

prevention of infections after surgical interventions.

The drug Augmentin^® CP is indicated for the treatment of bacterial infections of the following localizations caused by microorganisms sensitive to the combination of amoxicillin with clavulanic acid:

respiratory tract infections, such as community-acquired pneumonia, exacerbation of chronic bronchitis, acute bacterial sinusitis, usually caused by Streptococcus pneumoniae (including penicillin-resistant strains), Haemophilus influenzae¹, Moraxella catarrhalis¹ and Streptococcus pyogenes,

prevention of local infections after surgery in dentistry.

¹ Some strains of these bacteria produce beta-lactamases, which makes them insensitive to amoxicillin monotherapy.

Infections caused by amoxicillin-sensitive microorganisms can be treated with Augmentin^® CP, since amoxicillin is one of its active ingredients. The drug Augmentin^® CP is also indicated for the treatment of mixed infections caused by microorganisms sensitive to amoxicillin, as well as beta-lactamase-producing microorganisms sensitive to the combination of amoxicillin with clavulanic acid.

The drug Augmentin^® CP demonstrated efficacy against strains S. pneumoniae, resistant to penicillin (strains with MPC ≥2 mg/l).

Drugs containing a combination of amoxicillin with clavulanic acid should be used in accordance with the Russian guidelines for antibiotic therapy and regional data on the sensitivity of pathogens to the combination of amoxicillin with clavulanic acid.

The sensitivity of bacteria to the combination of amoxicillin with clavulanic acid varies depending on the region and over time. Where possible, local sensitivity data should be taken into account. If necessary, microbiological samples should be collected and analyzed for bacteriological sensitivity.

It is also used for the prevention of infections that are associated with major surgical operations on the gastrointestinal tract, in the pelvis, head and neck, on the heart, kidneys, and bile ducts.

Symptoms: there may be symptoms from the gastrointestinal tract and violations of the water-electrolyte balance. Amoxicillin crystalluria is described, which in some cases led to the development of renal failure (see "Special instructions").

Treatment: symptoms from the gastrointestinal tract-symptomatic therapy, paying special attention to the normalization of the water-electrolyte balance. Amoxicillin and clavulanic acid can be removed from the bloodstream by hemodialysis.

Symptoms: nausea, diarrhea, vomiting.

Treatment: symptomatic, effective hemodialysis.

The drug Amoxiclav^® it is a combination of amoxicillin and clavulanic acid.

Amoxicillin is a semi-synthetic penicillin (beta-lactam antibiotic) that inhibits one or more enzymes (often referred to as penicillin-binding proteins, PSBs) on the pathway of the biosynthesis of peptidoglycan, which is an integral structural component of the bacterial cell wall. Inhibition of peptidoglycan synthesis leads to a loss of cell wall strength, which usually causes the lysis and death of microbial cells.

Amoxicillin is destroyed by the action of beta-lactamases produced by resistant bacteria, so the spectrum of activity of amoxicillin does not include microorganisms that produce these enzymes.

Clavulanic acid is a beta-lactam structurally related to penicillins. It inhibits certain beta-lactamases, thereby preventing the inactivation of amoxicillin and expanding its range of activity, including bacteria that are usually resistant to amoxicillin, as well as other penicillins and cephalosporins. By itself, clavulanic acid does not have a clinically significant antibacterial effect.

The drug Amoxiclav^® it has a bactericidal effect in vivo for the following microorganisms:

- gram-positive airbags — Staphylococcus aureus*, Streptococcus pneumoniae, Streptococcus pyogenes,

- gram-negative aerobes — Enterobacter spp.**, Escherichia coli*, Haemophilus influenzae*, species of the genus Klebsiella*, Moraxella catarrhalis* (Branhamella catarrhalis).

The drug Amoxiclav^® it has a bactericidal effect in vitro for the following microorganisms (however, the clinical significance is still unknown):

- gram-positive airbags — Bacillis anthracis*, species of the genus Corynebacterium, Enterococcus faecalis*, Enterococcus faecium*, Listeria monocytogenes, Nocardia asteroides, coagulase-negative staphylococci* (including Staphylococcus epidermidis), Streptococcus agalactiae, other species of the genus Streptococcus, Streptococcus viridans,

- gram-positive anaerobes - species of the genus Clostridium, species of the genus Peptococcus, species of the genus Peptostreptococcus,

- gram-negative aerobes — Bordetella pertussis, species of the genus Brucella, Gardnerella vaginalis, Helicobacter pylori, species of the genus Legionella, Neisseria gonorrhoeae*, Neisseria meningitidis*, Pasteurella multocida, Proteus mirabilis*, Proteus vulgaris*, species of the genus Salmonella*, species of the genus Shigella*, Vibrio cholerae, Yersinia enterocolitica*,

- gram-negative anaerobes - species of the genus Bacteroides* (including Bacteroides fragilis), species of the genus Fusobacterium*,

- other — Borrelia burgdorferi, Chlamydia spp., Leptospira icterohaemorrhagiae, Treponema pallidum.

* Some strains of these bacterial species produce beta-lactamases, which contributes to their insensitivity to amoxicillin monotherapy.

** Most strains of these bacteria are resistant to the amoxicillin/clavulanic acid combination in vitro However, the clinical efficacy of this combination has been demonstrated in the treatment of urinary tract infections caused by these strains.

Amoxicillin is a broad-spectrum semi-synthetic antibiotic with activity against many gram-positive and gram-negative microorganisms. At the same time, amoxicillin is susceptible to destruction by beta-lactamases, and therefore the spectrum of activity of amoxicillin does not extend to microorganisms that produce this enzyme.

Clavulanic acid, a beta-lactamase inhibitor structurally related to penicillins, has the ability to inactivate a wide range of beta-lactamases found in microorganisms resistant to penicillins and cephalosporins. Clavulanic acid has sufficient efficacy against plasmid beta-lactamases, which most often cause bacterial resistance, and is less effective against chromosomal type 1 beta-lactamases, which are not inhibited by clavulanic acid.

The presence of clavulanic acid in the preparation Augmentin^® protects amoxicillin from destruction by enzymes-beta-lactamases, which allows you to expand the antibacterial spectrum of amoxicillin.

Delayed release of amoxicillin in Augmentin^® CP allows you to maintain the sensitivity of those strains S. pneumoniae, in which resistance to amoxicillin is due to penicillin-binding proteins (penicillin-resistant S. pneumoniae, or PRSP).

Below is the activity of the combination of amoxicillin with clavulanic acid in vitro.

¹ For these types of microorganisms, the clinical efficacy of the combination of amoxicillin with clavulanic acid has been demonstrated in clinical studies.

² Strains of these types of bacteria do not produce beta-lactamases. The sensitivity of amoxicillin monotherapy suggests a similar sensitivity to the combination of amoxicillin with clavulanic acid.

Resistance

Cross-resistance. Amoxicillin directly demonstrates cross-resistance with other beta-lactam antibiotics, as well as a combination of beta-lactam antibiotics with beta-lactamase inhibitors and cephalosporins.

Mechanisms of resistance. Clavulanic acid protects amoxicillin from the damaging effects of beta-lactamases. Delayed release of the active ingredients of the drug Augmentin^® CP increases the effectiveness of amoxicillin against microorganisms whose resistance is due to modification of penicillin-binding proteins.

Bactericidal against a wide range of gram-positive and gram-negative microorganisms, aerobic and anaerobic pathogens (including those strains that have developed resistance to beta-lactam antibiotics due to the production of beta-lactamases).

Active against aerobic gram-positive bacteria (including beta-lactamase-producing strains): Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pyogenes, Streptococcus anthracis, Streptococcus pneumoniae, Streptococcus viridans, Enterococcus faecalis, Corynebacterium spp., Listeria monocytogenes, anaerobic gram-positive bacteria: Clostridium spp., Peptococcus spp., Peptostreptococcus spp, aerobic gram-negative bacteria (including beta-lactamase-producing strains): Escherichia coli, Proteus mirabilis, Proteus vulgaris, Klebsiella spp., Salmonella spp., Shigella spp., Bordetella pertussis, Yersinia enterocolitica, Gardnerella vaginalis, Neisseria meningitidis, Neisseria gonorrhoeae, Moraxella catarrhalis, Haemophilus influenzae , Haemophilus ducreyi, Yersinia multocida (formerly Pasteurella), Campylobacter jejuni, anaerobic gram-negative bacteria (including beta-lactamase-producing strains): Bacteroides spp., including Bacteroides fragilis.

Clavulanic acid suppresses types II, III, IV and V of beta-lactamases, is inactive against type I beta-lactamases produced by Enterobacter spp., Pseudomonas aeruginosa, Serratia spp., Acinetobacter spp. Clavulanic acid has a high tropicity to penicillinases and forms a stable complex with the enzyme, which prevents the enzymatic degradation of amoxicillin under the influence of beta-lactamases.

The main pharmacokinetic parameters of amoxicillin and clavulanic acid are similar. Amoxicillin and clavulanic acid are well soluble in aqueous solutions with a physiological pH value and after taking the drug Amoxiclav^® inside, they are quickly and completely absorbed from the gastrointestinal tract. The absorption of the active substances-amoxicillin and clavulanic acid-is optimal in the case of taking the drug at the beginning of a meal.

The bioavailability of amoxicillin and clavulanic acid after oral administration is about 70%.

Peak plasma concentrations are reached approximately 1 h after administration. Values of C_max make up for amoxicillin (depending on the dose) 3-12 mcg/ml, for clavulanic acid-about 2 mcg/ml.

C_max in the blood plasma after bolus injection at a dose of 1.2 g (1000 200 mg) of the drug is 105.4 mg/l - for amoxicillin and 28.5 mg / l — for clavulanic acid.

When using the drug Amoxiclav^® The plasma concentrations of amoxicillin/clavulanic acid are similar to those of oral administration of the corresponding doses of amoxicillin or clavulanic acid separately at equivalent doses.

Both components are characterized by a sufficient V_d in various organs, tissues and fluid environments of the body (including in the lungs, abdominal organs, adipose, bone and muscle tissues, pleural, synovial and peritoneal fluids, in the skin, bile, urine, purulent discharge, sputum, interstitial fluid).

Plasma protein binding is moderate — 25% for clavulanic acid and 18% for amoxicillin.

V_d it is approximately 0.3–0.4 l / kg for amoxicillin and approximately 0.2 l / kg for clavulanic acid.

Amoxicillin and clavulanic acid do not penetrate the blood-brain barrier in non-inflamed meninges.

Amoxicillin (like most penicillins) is excreted in breast milk. Trace amounts of clavulanic acid were also found in breast milk. Amoxicillin and clavulanic acid penetrate the placental barrier.

Amoxicillin is mainly excreted by the kidneys, whereas clavulanic acid is excreted by both the renal and extrarenal mechanisms. After a single oral administration of one tablet 250 125 mg or 500 125 mg, approximately 60-70% of amoxicillin and 40-65% of clavulanic acid are excreted unchanged in the urine for the first 6 hours. About 10-25% of the initial dose of amoxicillin is excreted in the urine as inactive penicillic acid. Clavulanic acid in the human body undergoes intensive metabolism with the formation of 2,5-dihydro-4 - (2-hydroxyethyl) - 5-oxo-1H-pyrrole-3-carboxylic acid and 1-amino-4-hydroxy-butane-2-one and is excreted in the urine and feces

Average T_1/2 amoxicillin/clavulanic acid is approximately 1 h, the average total clearance is approximately 25 l / h in healthy patients. In the course of various studies, it was found that the excretion of amoxicillin in the urine for 24 hours is approximately 50-85%, clavulanic acid-27-60%. The greatest amount of clavulanic acid is excreted within the first 2 hours after ingestion.

The pharmacokinetic parameters of amoxicillin and clavulanic acid are summarized in Table 1.

Table 1

Patients with impaired liver function

In patients with severe renal insufficiency T_1/2 increases to 7.5 hours for amoxicillin and 4.5 hours for clavulanic acid.

For patients with impaired liver function, the dose of the drug should be selected with caution: constant monitoring of the liver condition is necessary.

Both components are removed by hemodialysis and minor amounts are removed by peritoneal dialysis.

Suction

Both active ingredients of the drug Augmentin^® CP, amoxicillin and clavulanic acid, are well soluble in aqueous solutions with a physiological pH value, are quickly and completely absorbed from the gastrointestinal tract after oral administration. The absorption of active substances is optimal in the case of taking the drug at the beginning of a meal.

The pharmacokinetic parameters of amoxicillin and clavulanic acid after taking 2 tablets of the drug Augmentin are shown below^® CP by healthy volunteers at the beginning of a meal.

Table 1

Average values of pharmacokinetic parameters

¹ For bacteria with an MPC of 4 mg/l.

² T>MPC, h (%) — the time (as a percentage of the time interval between doses) during which the concentration of the drug in the blood is higher than the BMD for a particular pathogen.

The drug Augmentin^® CP has a unique pharmacological profile, the T>MPC index characteristic of this drug is not achieved when taking tablets with immediate release of active substances containing a combination of amoxicillin and clavulanic acid.

Distribution

As with the intravenous administration of a combination of amoxicillin and clavulanic acid, therapeutic concentrations of amoxicillin and clavulanic acid are created in various tissues and interstitial fluid (gallbladder, abdominal tissue, skin, adipose and muscle tissue, synovial and peritoneal fluid, bile, purulent discharge).

Amoxicillin and clavulanic acid have a weak degree of binding to plasma proteins. Studies have shown that about 25% of the total amount of clavulanic acid and 18% of amoxicillin in the blood plasma binds to plasma proteins.

In animal studies, no accumulation of the components of the drug Augmentin was found^® CP in any body.

Amoxicillin, like most penicillins, penetrates into breast milk. Trace amounts of clavulanic acid were also found in breast milk. With the exception of the possibility of diarrhea and candidiasis of the oral mucosa, no other negative effects of amoxicillin and clavulanic acid on the health of infants fed with breast milk are known.

Studies of reproductive function in animals when taking the drug Augmentin^® CP showed that amoxicillin and clavulanic acid penetrate the placental barrier. However, there was no negative effect on the fetus.

Metabolism

10-25% of the initial dose of amoxicillin is excreted by the kidneys as an inactive metabolite (penicillic acid). Clavulanic acid undergoes intensive metabolism to 2,5-dihydro-4 - (2-hydroxyethyl) - 5-oxo-1H-pyrrole-3-carboxylic acid and 1-amino-4-hydroxy-butane-2-one and is excreted by the kidneys, through the gastrointestinal tract, and with exhaled air in the form of carbon dioxide.

Output

Like other penicillins, amoxicillin is mainly excreted by the kidneys, while clavulanic acid is excreted through both the renal and extrarenal mechanisms.

Studies have shown that, on average, about 60-70% of amoxicillin and about 40-65% of clavulanic acid is excreted unchanged by the kidneys.

Simultaneous administration of probenecid slows the elimination of amoxicillin, but does not slow the elimination of clavulanic acid (see "Interaction").

The pharmacokinetics of amoxicillin and clavulanic acid are similar. After intravenous administration in doses of 1200 mg and 600 mg S_max amoxicillin — 105.4 mcg / ml and 32.2 mcg/ml, respectively, clavulanic acid-28.5 mcg/ml and 10.5 mcg/ml, respectively. Plasma protein binding: amoxicillin-17-20%, clavulanic acid-23-30%. Both components are metabolized in the liver: amoxicillin - 10% of the administered dose, clavulanic acid-50%. T_1/2 after intravenous administration at a dose of 1.2 g and 600 mg-0.9 and 1.07 hours for amoxicillin, 0.9 and 1.12 hours-for clavulanic acid, respectively. It is mainly excreted by the kidneys (glomerular filtration and tubular secretion): 50-78% and 25-40% of the dose of amoxicillin and clavulanic acid, respectively, is excreted unchanged during the first 6 hours after administration.

For all dosage forms

Antacids, glucosamine, laxatives, aminoglycosides slow down the absorption, ascorbic acid increases the absorption.

Diuretics, allopurinol, phenylbutazone, NSAIDs and other drugs that block tubular secretion (probenecid) increase the concentration of amoxicillin (clavulanic acid is mainly excreted by glomerular filtration).

Concomitant use of Amoxiclav^® and methotrexate increases the toxicity of methotrexate.

Administration together with allopurinol increases the frequency of exanthema. Concomitant use with disulfiram should be avoided.

Reduces the effectiveness of drugs, during the metabolism of which PABA is formed, ethinyl estradiol-the risk of breakthrough bleeding.

The literature describes rare cases of increased INR in patients with the combined use of acenocumarol or warfarin and amoxicillin. If concomitant use with anticoagulants is necessary, PV or INR should be carefully monitored when prescribing or discontinuing the drug.

The combination with rifampicin is antagonistic (mutual weakening of the antibacterial effect). The drug Amoxiclav^® it should not be used simultaneously in combination with bacteriostatic antibiotics (macrolides, tetracyclines), sulfonamides due to a possible decrease in the effectiveness of the drug Amoxiclav^®.

The drug Amoxiclav^® reduces the effectiveness of oral contraceptives.

For dispersible tablets and powder for preparation of suspension for oral administration in addition

Increases the effectiveness of indirect anticoagulants (suppressing intestinal microflora, reduces the synthesis of vitamin K and prothrombin index). In some cases, taking the drug may prolong the PV, in this regard, caution should be exercised when using anticoagulants and Amoxiclav simultaneously^®Quicktab.

Probenecid reduces the excretion of amoxicillin, increasing its serum concentration.

In patients receiving mycophenolate mofetil, after the start of the combination of amoxicillin with clavulanic acid, there was a decrease in the concentration of the active metabolite — mycophenolic acid, before taking the next dose of the drug by approximately 50%. Changes in this concentration may not accurately reflect the overall changes in mycophenolic acid exposure.

For powder for preparation of solution for intravenous administration in addition

The drug Amoxiclav^® and aminoglycoside antibiotics are chemically incompatible.

The drug Amoxiclav^® do not mix in a syringe or infusion bottle with other drugs.

Avoid mixing with solutions of dextrose, dextran, sodium bicarbonate, as well as with solutions containing blood, proteins, lipids.

Simultaneous use of the drug Augmentin^® CP and probenecid are not recommended. Probenecid reduces the tubular secretion of amoxicillin, and therefore the simultaneous use of the drug Augmentin^® CP and probenecid can lead to an increase and persistence in the blood concentration of amoxicillin, but not clavulanic acid.

Concomitant use of allopurinol and amoxicillin may increase the risk of skin allergic reactions. Currently, there is no data in the literature on the simultaneous use of a combination of amoxicillin with clavulanic acid and allopurinol.

Penicillins are able to slow the elimination of methotrexate from the body by inhibiting its tubular secretion, so the simultaneous use of the drug Augmentin^® CP and methotrexate may increase the toxicity of methotrexate.

Like other antibacterial drugs, the drug Augmentin^® CP can affect the intestinal microflora, leading to a decrease in the absorption of estrogens from the gastrointestinal tract and a decrease in the effectiveness of combined oral contraceptives.

The literature describes rare cases of increased MHO in patients with the combined use of acenocumarol or warfarin and amoxicillin. If necessary, simultaneous administration or withdrawal of the drug Augmentin^® CP with PV or MHO anticoagulants should be carefully monitored, and the dose of anticoagulants for oral administration may need to be adjusted.

Pharmacologically incompatible with solutions containing blood, proteins, lipids, glucose, dextran, bicarbonate, simultaneous administration with allopurinol increases the risk of exanthema, avoid simultaneous administration with disulfiram.
