Amoxiclav tab 625mg (500mg/125mg) №15
Description:
White or almost white oval biconvex film-coated tablets. The main active ingredient Amoxicillin + clavulanic acid Release form Tablets Dosage Each tablet (625 mg) contains 500 mg of amoxicillin in the form of trihydrate and 125 mg of clavulanic acid in the form of potassium salt – a ratio of 4: 1 more an enzyme (often referred to as a penicillin-binding protein) during the biosynthesis of peptidoglycan, an integral component of the bacterial cell wall. Inhibition of peptidoglycan synthesis results in a loss of cell wall strength, which usually results in cell lysis and death. Amoxicillin is destroyed by the action of beta-lactamases produced by resistant bacteria, so it is inactive against microorganisms that produce these enzymes. Clavulanic acid is a beta-lactam structurally similar to penicillins. It inhibits some beta-lactamases and thus prevents the inactivation of amoxicillin. By itself, clavulanic acid does not have a clinically useful antibacterial effect. The time to maintain concentrations above the minimum inhibitory (T> MIC) is recognized as the main determinant of the effectiveness of amoxicillin. Mechanisms of resistance There are two main mechanisms of bacterial resistance to amoxicillin/clavulanic acid: inactivation by bacterial beta-lactamases that are insensitive to the inhibitory effects of clavulanic acid, including class B, C, and D beta-lactamases; a change in penicillin-binding proteins, as a result of which the affinity of antibacterial drugs for target structures decreases. Bacterial impermeability or active drug transport mechanisms out of the bacterial cell can directly cause or contribute to resistance, especially in Gram-negative bacteria. Limits of sensitivity Minimum inhibitory concentrations for amoxicillin/clavulanic acid correspond to the limits of sensitivity established by the European Committee for the Evaluation of Antibiotic Susceptibility (EUCAST) Organism Limits of sensitivity (μg / ml) Sensitivity Intermediate sensitivity Resistance Haemophilus influenzae1 ? 1->1 Moraxella catarrhalis1 ? 1->1 Staphylococcus aureus2 ? 2 – > 2 Coagulase-negative staphylococcus aureus2 ? 0.25 > 0.25 Enterococcus2? 4 8 > 8 Streptococcus A, B, C, G5 ? 0.25 – > 0.25 Streptococcus pneumoniae3 ? 0.5 1-2 > 2 Enterobacteria1.4 – – > 8 Gram-negative anaerobes1 ? 4 8 > 8 Gram-positive anaerobes1 ? 4 8 > 8 Non-species-specific limits1 ? 2 4-8 > 8 1 The obtained values correspond to the concentrations of amoxicillin. For the purpose of sensitivity assessment, a fixed concentration of clavulanic acid is used – 2 mg / l. 2 The values obtained correspond to the concentrations of oxacillin. 3 Limit values in the table are based on ampicillin susceptibility limits. 4 The resistance limit R > 8 mg/l guarantees the antibiotic resistance of all isolated strains with resistance mechanisms. 5 Limit values in the table are based on sensitivity limits for benzylpenicillin. The prevalence of resistance in individual species is geographically and temporally dependent, so it is desirable to obtain local information on antibiotic resistance before starting therapy, especially in the case of severe infections. In cases where local indicators of antibiotic resistance cast doubt on the appropriateness of the drug for at least some types of infections, you should seek the help of appropriate specialists. Usually susceptible species Gram-positive aerobes: Enterococcus faecalis, Gardnerella vaginalis, Staphylococcus aureus (methicillin-susceptible strains)?, Coagulase-negative Staphylococci (methicillin-susceptible strains)?, Streptococcus agalactiae, Streptococcus pneumoniae1, Streptococcus pyogenes and other beta-hemolytic streptococci, group Streptococcus viridans Gram-negative aerobes: Capnocytophaga spp., Eikenella corrodens, Haemophilus influenzae2, Moraxella catarrhalis, Pasteurella multocida Anaerobes: Bacteroides fragilis, Fusobacterium nucleatum, Prevotella spp. Species with possible development of acquired resistance Gram-positive aerobes: Enterococcus faecium$ Gram-negative aerobes: Escherichia coli, Klebsiella oxytoca, Klebsiella pneumoniae, Proteus mirabilis, Proteus vulgaris Species with natural resistance Gram-negative aerobes: Acinetobacter sp., Citrobacter freundii, Enterobacter sp., Legionella pneumophila, Morganella morganii, Providencia spp, Pseudomonas sp., Serratia sp., Stenotrophomonas maltophilia Other organisms: Chlamydophyla pneumoniae, Chlamydophyla psittaci, Coxiella burnetti, Mycoplasma pneumoniae $ Natural intermediate susceptibility in the absence of an acquired resistance mechanism. ? All methicillin-resistant staphylococci are resistant to amoxicillin/clavulanic acid. 1 Infections caused by penicillin-resistant strains of Streptococcus pneumoniae should not be treated with this dosage form of the drug, if there is a high risk that the alleged pathogens are resistant, due not to the production of beta-lactamase sensitive to clavulanic acid inhibition, but to a change in penicillin-binding proteins (see “Method of application and dosage” and “Precautions”). 2 In some EU countries, strains with reduced sensitivity have been identified, occurring at a frequency above 10%. Pharmacokinetics Amoxicillin and clavulanic acid are completely soluble in water at physiological pH. Both components are quickly and well absorbed after oral administration. Their absorption improves if the drug is taken immediately before meals. When administered orally, the bioavailability of amoxicillin and clavulanic acid reaches approximately 70%. The plasma concentration profiles of both components are similar, the time to peak concentration (Tmax) for each substance is approximately one hour. When groups of healthy volunteers took the 875 mg/125 mg combination tablet twice daily on an empty stomach, peak serum concentrations (Cmax) were 11.64 ± 2.78 μg/mL for amoxicillin and 2.18 ± 0.99 μg /ml for clavulanic acid. The time to reach maximum serum concentration (Tmax) was 1.5 hours (range 1.0-2.5) for amoxicillin and 1.25 hours (range 1.0-2.0) for clavulanic acid. Mean T1/2 values were 1.19 ± 0.21 h for amoxicillin and 0.96 ± 0.12 h for clavulanic acid. Serum concentrations of amoxicillin and clavulanic acid achieved by oral administration of the combined preparation are similar to those obtained by oral administration of equivalent doses of amoxicillin or clavulanic acid alone. About 25% of the total plasma clavulanic acid and 18% of the total plasma amoxicillin is in a protein-bound state. The apparent volume of distribution is about 0.3-0.4 l/kg for amoxicillin and about 0.2 l/kg for clavulanic acid. After intravenous administration, amoxicillin and clavulanic acid are found in the gallbladder, abdominal wall tissues, skin, adipose tissue, muscle tissue, synovial and peritoneal fluids, bile and pus. Amoxicillin only slightly penetrates into the cerebrospinal fluid. Amoxicillin, like most penicillins, passes into breast milk. Trace amounts of clavulanic acid are also found in breast milk (see Pregnancy and Breastfeeding). Both amoxicillin and clavulanic acid cross the placental barrier. Amoxicillin is partially excreted in the urine in the form of inactive penicillic acid in volumes equivalent to no more than 10-25% of the initial dose. Clavulanic acid is extensively metabolized in the human body, excreted in urine and feces, as well as in the form of carbon dioxide with exhaled air. The main route of excretion of amoxicillin is the kidneys, while clavulanic acid is excreted from the body using renal and extrarenal mechanisms. The amoxicillin/clavulanic acid combination has a mean half-life of about one hour and a mean total clearance of about 25 L/h in healthy subjects. Approximately 60-70% of amoxicillin and approximately 40-65% of clavulanic acid are excreted unchanged in the urine in the first 6 hours after a single dose of amoxicillin/clavulanic acid 250 mg/125 mg or 500 mg/125 mg tablets. The level of excretion in the urine within a 24-hour period is 50-85% for amoxicillin and 27-60% for clavulanic acid. The maximum amount of clavulanic acid is excreted in the first two hours after taking the drug. Age The half-life of amoxicillin in children aged three months to two years, older children and adults is similar. In the elderly, the dose is selected with caution due to the possible decrease in kidney function and, if necessary, regularly check the work of the kidneys. Gender The pharmacokinetics of amoxicillin or clavulanic acid does not depend on the gender of the patient. Impaired renal function The total plasma clearance of amoxicillin and clavulanic acid decreases in proportion to the decrease in renal function. The decrease in clearance is more pronounced for amoxicillin than for clavulanic acid, since the proportion of amoxicillin excreted by the kidneys is higher. In renal insufficiency, doses are selected so as to avoid excessive accumulation of amoxicillin while maintaining adequate levels of clavulanic acid (see “Method of application and dosage”). Hepatic insufficiency In patients with hepatic insufficiency, the drug is prescribed with caution and regularly monitor liver function. Indications for use Amoxiclav is intended for the treatment of the following infections caused by strains sensitive to the combination of amoxicillin / clavulanic acid: Acute bacterial sinusitis (adequately diagnosed); Acute otitis media; Exacerbation of chronic bronchitis (adequately diagnosed); community-acquired pneumonia; Cystitis; Pyelonephritis; Infections of the skin and soft tissues, in particular inflammation of the subcutaneous tissue, animal bites, severe dental abscesses with widespread phlegmon; Infections of bones and joints, in particular osteomyelitis. Consideration should be given to official guidelines on the appropriate use of antibacterial drugs. Dosage and administration Doses reflect the content of amoxicillin and clavulanic acid. When choosing a dose for the treatment of specific infections, the following factors are taken into account: suspected pathogens and their possible susceptibility to antibacterial drugs; the severity and location of the infection; age, weight, and kidney function, as listed below. The use of other dosage forms of the drug (for example, with higher doses of amoxicillin and / or with a different dose ratio of amoxicillin / clavulanic acid) is considered as necessary. When taking Amoxiclav 375 mg tablets at the doses recommended below, adults and children weighing ? 40 kg will receive a total daily dose of 750 mg amoxicillin/375 mg clavulanic acid. When taking Amoxiclav 625 mg tablets at the doses recommended below, adults and children weighing ? 40 kg will receive a total daily dose of 1500 mg amoxicillin/375 mg clavulanic acid. Children weighing < 40 kg will receive doses ranging from 20 mg/5 mg/kg/day to 60 mg/15 mg/kg/day, with a maximum daily dose of 2400 mg amoxicillin/600 mg clavulanic acid. If you need a higher daily dose of amoxicillin, it is recommended to choose a different dosage form of the drug in order to avoid taking excessively high daily doses of clavulanic acid. The duration of treatment should not exceed 14 days without revision (see information on long-term therapy in the Precautions section). Adults and children weighing ? 40 kg One 375 mg tablet or one 625 mg tablet three times a day. Children weighing < 40 kg Amoxiclav 375 mg film-coated tablets are not recommended for use in children weighing < 40 kg. Dose from 20 mg / 5 mg / kg / day to 60 mg / 15 mg / kg / day, divided into three doses. The table below shows doses (mg/kg body weight) in children weighing 25 to 40 kg after taking one 625 mg tablet. Body weight (kg) 40 35 30 25 Recommended single dose (mg/kg body weight) Amoxicillin (mg/kg body weight) after a single dose of one tablet 625 mg 12.5 14.3 16.7 20.0 6.67 – 20 Clavulanic acid (mg/kg body weight) after a single dose of one 625 mg tablet) 3.1 3.6 4.2 5.0 1.67 - 5 For the treatment of children under the age of six years or weighing less than 25 kg, it is preferable to use a suspension. For the treatment of children from 6 to 12 years old, the optimal dosage form is 625 mg tablets taken 2 times a day. Clinical data on the use of dosage forms of the drug with a ratio of active ingredients 4:1 at doses above 40 mg / 10 mg / kg / day for the treatment of children under the age of two years are not available. Elderly patients Dose adjustment is not required. Patients with impaired renal function The dose is adjusted based on the maximum recommended dose of amoxicillin. Patients with a creatinine clearance of more than 30 ml / min dose adjustment is not required. Adults and children weighing ? 40 kg Creatinine clearance: 10-30 ml/min 1 tablet 375 mg or 1 tablet 625 mg twice a day. Creatinine clearance: < 10 ml/min 1 tablet 375 mg or 1 tablet 625 mg once a day. Hemodialysis 1 tablet 625 mg every 24 hours plus 625 mg during dialysis and another dose at the end of dialysis (as serum concentrations of amoxicillin and clavulanic acid decrease during dialysis). Children weighing <40 kg In children weighing <40 kg with a creatinine clearance of less than 30 ml / min, the use of Amoxiclav with a ratio of amoxicillin and clavulanic acid 2: 1 is not recommended due to the lack of the possibility of dose adjustment. In such patients, the use of Amoxiclav forms with a ratio of amoxicillin and clavulanic acid of 4: 1 is recommended. Creatinine clearance: 10-30 ml/min 15 mg/3.75 mg/kg twice daily (maximum 500 mg/125 mg twice daily). Creatinine clearance: < 10 ml/min 15 mg/3.75 mg/kg once daily (maximum 500 mg/125 mg once daily). Hemodialysis 15 mg/3.75 mg/kg once a day. Before hemodialysis 15 mg/3.75 mg/kg. To restore the appropriate concentrations of the drug in the blood after hemodialysis, take another dose of 15 mg / 3.75 mg / kg. Patients with impaired liver function Use with caution. Regularly monitor liver function (see "Contraindications" and "Precautions"). Method of application For oral administration. Take immediately before meals to minimize possible gastrointestinal side effects. Treatment can be started with the parenteral form of the drug, following the instructions attached to it, and continue with the oral dosage form. Use during pregnancy and lactation Limited data on the use of the drug during pregnancy do not indicate an increased risk of congenital anomalies. In women with preterm preterm rupture of membranes, prophylactic treatment with amoxicillin/clavulanic acid has been potentially associated with an increased risk of neonatal necrotizing enterocolitis. The use of the drug during pregnancy should be avoided unless the doctor considers treatment necessary. Both active ingredients are excreted in breast milk (data on the effect of clavulanic acid on breastfed children are not available). Breastfed babies may develop diarrhea and fungal infections of the mucous membranes, which may require stopping breastfeeding. The possibility of sensitization should be considered. Therapy with the drug during breastfeeding is possible only after assessing the benefit-risk ratio by the attending physician. Influence on the ability to drive vehicles and work with mechanisms It is possible to develop undesirable effects (for example, allergic reactions, dizziness, convulsions), potentially affecting the performance of these functions. Precautions Before prescribing the drug, a detailed history should be taken regarding previous hypersensitivity reactions to penicillins, cephalosporins or other β-lactam antibiotics. There have been reports of the development of serious hypersensitivity reactions, sometimes fatal, (including anaphylactoid and severe skin adverse reactions) in patients receiving penicillin therapy. The risk of such reactions is highest in patients with a history of hypersensitivity reactions to penicillins. In the event of an allergic reaction, it is necessary to stop treatment with Amoxiclav and start alternative therapy. In cases of proven susceptibility of infectious agents to amoxicillin, consider switching from Amoxiclav to amoxicillin in accordance with official guidelines. This dosage form of the drug is not suitable for use if there is a high risk that the alleged pathogens are resistant, due not to the production of beta-lactamase sensitive to clavulanic acid inhibition, but to a change in penicillin-binding proteins (including resistant S. pneumoniae). In patients with impaired renal function or receiving high-dose therapy, seizures may develop (see "Side Effects"). Therapy with Amoxiclav should be avoided if infectious mononucleosis is suspected, because in patients with this disease, amoxicillin can cause a skin rash, which makes it difficult to diagnose the disease. The simultaneous use of allopurinol during treatment with amoxicillin may increase the likelihood of allergic skin reactions. Long-term treatment with Amoxiclav sometimes leads to an overgrowth of insensitive microflora. The appearance at the beginning of treatment of febrile generalized erythema with fever and the formation of pustules at the beginning of therapy is a potential symptom of acute generalized exanthemic pustulosis (AGEP). This reaction requires discontinuation of treatment with Amoxiclav and is a contraindication for any subsequent administration of amoxicillin. Amoxiclav is prescribed with caution to patients with impaired liver function. Hepatic insufficiency caused by the use of the drug has been observed mainly in men and elderly patients and may be associated with long-term therapy. These phenomena have been very rarely observed in children. In all populations, signs and symptoms usually occur during or shortly after treatment, but in some cases become apparent only a few weeks after treatment is stopped. They are usually reversible. Liver failure can be severe and, in extremely rare cases, be fatal. It is almost always seen in patients with a serious underlying disease or who are concomitantly taking drugs with a known potential for liver damage. Antibiotic-induced colitis occurs with almost all antibiotics and can range in severity from mild to life-threatening. In this regard, it is important to recognize this diagnosis in patients with diarrhea, during or after taking any antibiotic. In case of colitis caused by an antibiotic, Amoxiclav should be stopped immediately, a doctor's consultation should be carried out, and appropriate therapy should be started. In this situation, the use of drugs that depress peristalsis is contraindicated. During long-term therapy, periodic evaluation of the functions of various organ systems, including the kidneys, liver, and hematopoietic organs, is recommended. In rare cases, while taking the drug, prolongation of prothrombin time was noted. With the simultaneous use of Amoxiclav and anticoagulants, it is necessary to regularly monitor the relevant indicators. Dose adjustment of oral anticoagulants may be required to achieve the desired level of anticoagulation. In patients with renal insufficiency, the dose should be adjusted according to the degree of insufficiency. In patients with reduced diuresis, crystalluria very rarely occurs, mainly with parenteral therapy. During the administration of high doses of amoxicillin, it is recommended to take a sufficient amount of fluid and maintain adequate diuresis to reduce the likelihood of amoxicillin-associated crystalluria. In patients with a catheter installed in the bladder, it is imperative to regularly monitor its patency. If it is necessary to evaluate the level of glucose in the urine during treatment with amoxicillin, enzymatic methods with glucose oxidase should be used, since non-enzymatic methods sometimes give false positive results. The presence of clavulanic acid in Amoxiclav can cause non-specific binding of IgG and albumin to erythrocyte membranes, which can lead to false positive Coombs test results. There have been cases of positive results of enzyme-linked immunosorbent assay (ELISA) for Aspergillus in patients treated with the drug, in whom the absence of infections caused by Aspergillus was subsequently determined. Cross-reactions with non-Aspergillus polysaccharides and polyfuranoses have been noted in the ELISA test for Aspergillus. Positive test results in patients taking Amoxiclav should be interpreted with caution and confirmed by other diagnostic methods. Interaction with other drugs Oral anticoagulants Cases of an increase in the international normalized ratio (INR) in patients receiving maintenance therapy with acenocoumarol or warfarin against the background of the prescribed course of amoxicillin are described. If necessary, the simultaneous administration of drugs carefully monitor the prothrombin time or INR at the beginning and after stopping treatment with amoxicillin. Dose adjustment of oral anticoagulants may be required. Methotrexate Penicillins may reduce the excretion of methotrexate, which may lead to increased toxicity. Probenecid It is not recommended to use simultaneously probenecid, which reduces the secretion of amoxicillin by the renal tubules. The simultaneous use of probenecid with Amoxiclav may lead to an increase and to a longer maintenance of the level of amoxicillin (but not clavulanic acid) in the blood. Mycophenolate mofetil In patients taking mycophenolate mofetil, after the start of oral amoxicillin and clavulanic acid, an approximately 50% decrease in the concentration of the active metabolite - mycophenolic acid (MPA) - was observed before taking the next dose of mycophenolate mofetil. Such a change in the concentration of MFC before taking the next dose may not indicate a change in the overall exposure of the MFC. Therefore, in the absence of clinical signs of graft dysfunction, there is usually no need to change the dose of mycophenolate mofetil. However, during such combination therapy and for some time after the end of antibiotic therapy, close medical supervision is necessary. Contraindications Hypersensitivity to the active or excipients of the drug, as well as to any penicillins. History of severe immediate hypersensitivity reactions (eg, anaphylaxis) to other beta-lactam drugs (eg, cephalosporins, carbapenems, or monobactams). History of jaundice or other liver damage associated with the use of amoxicillin / clavulanic acid. Composition Each tablet (625 mg) contains 500 mg amoxicillin trihydrate and 125 mg clavulanic acid potassium salt in a 4:1 ratio. Excipients: colloidal silicon dioxide, crospovidone, croscarmellose sodium, magnesium stearate, microcrystalline cellulose. Tablet shell: hydroxypropyl cellulose, ethyl cellulose, polysorbate, triethyl citrate, titanium dioxide, talc. Overdose: Gastrointestinal symptoms may develop, as well as a violation of the water and electrolyte balance. There have been cases of amoxicillin-associated crystalluria, sometimes leading to renal failure. Convulsions may develop in patients with impaired renal function or in those receiving high dose therapy. Amoxicillin precipitates in urinary catheters, predominantly after intravenous administration of large doses. It is necessary to regularly monitor the patency of catheters. For gastrointestinal symptoms, symptomatic treatment can be carried out, along with the restoration of fluid and electrolyte balance. Amoxicillin and potassium clavulanate can be excreted from the body by hemodialysis.
