Pharmacological action

Комбинированный препарат амоксициллина и клавулановой кислоты – ингибитора бета-лактамаз. Effective bactericidal, It inhibits the synthesis of bacterial cell wall.

It is active against aerobic gram-positive bacteria (including strains, producing beta-lactamase): Staphylococcus aureus; Aerobic Gram-negative bacteria: Enterobacter spp., Escherichia coli, Haemophilus influenzae, Klebsiella spp., Moraxella catarrhalis. The following pathogens are sensitive only in vitro: Staphylococcus epidermidis, Streptococcus pyogenes, Streptococcus anthracis, Streptococcus pneumoniae, Streptococcus viridans, Enterococcus faecalis, Corynebacterium spp., Listeria monocytogenes; anaerobic Clostridium spp., Peptococcus spp., Peptostreptococcus spp.; and Aerobic gram-negative bacteria (including strains, producing beta-lactamase): Proteus is wonderful, Proteus vulgaris, Salmonella spp., Shigella spp., Bordetella pertussis, Yersinia enterocolitica, Gardnerella vaginalis, Neisseria meningitidis, Neisseria gonorrhoeae, Haemophilus ducreyi, Yersinia multocida (Pasteurella ранее), Campylobacter jejuni; anaerobic gram-negative bacteria (including strains, producing beta-lactamase): Bacteroides spp., including Bacteroides fragilis.

Clavulanic acid inhibits II, III, IV and V types of beta-lactamases, not active against beta-lactamase I type, produced by Pseudomonas aeruginosa, Serratia spp., Acinetobacter spp. Clavulanic acid has a high affinity for penicillinases, thereby forming a stable complex with the enzyme, thus preventing the enzymatic degradation of amoxicillin under the influence of beta-lactamase.

Pharmacokinetics

After oral administration, the two components are quickly absorbed in the gastrointestinal tract. Simultaneous food intake does not affect absorption. TCmax

45 m. After oral dose 250/125 mg every 8 h Cmax амоксициллина – 2.18-4.5 ug / ml, клавулановой кислоты – 0.8-2.2 ug / ml, dose 500/125 mg every 12 h Cmax амоксициллина – 5.09-7.91 ug / ml, клавулановой кислоты – 1.19-2.41 ug / ml, dose 500/125 mg every 8 h Cmax амоксициллина – 4.94-9.46 ug / ml, клавулановой кислоты – 1.57-3.23 ug / ml, dose 875/125 mg Cmax амоксициллина – 8.82-14.38 ug / ml, клавулановой кислоты – 1.21-3.19 ug / ml.

After the on / in the doses 1000/200 and 500/100 mg Cmax амоксициллина – 105.4 and 32.2 ug / ml, respectively, а клавулановой кислоты – 28.5 and 10.5 ug / ml.

Time to reach the maximum inhibitory concentration 1 ug / mL for amoxycillin similar when applied through 12 and h 8 h in adults, and children.

Relationship to plasma proteins: амоксициллин – 17-20%, клавулановая кислота – 22-30%.

Both components are metabolized in the liver: амоксициллин – на 10% the dose of the administered dose, клавулановая кислота – на 50%.

T1/2 after receiving a dose of 375 and 625 mg - 1 and 1.3 h for amoxicillin, 1.2 and 0.8 ч – для клавулановой кислоты соответственно. T1/2 after / in a dose of 1200 and 600 mg - 0.9 and 1.07 ч – для амоксициллина, 0.9 and 1.12 ч – для клавулановой кислоты соответственно. Write mainly kidneys (glomerular filtration and tubular secretion): 50-78 and 25-40% of the administered dose of amoxycillin and clavulanic acid respectively output in unchanged form within the first 6 h after administration.

The maximum daily dose of clavulanic acid for adults and older children 12 years - 600 mg, for children up to 12 years - 10 mg / kg body weight.

With difficulty swallowing in adults is recommended to use suspension.

In preparing the slurry, syrup and drops as the solvent, use water.

At on / in adults and adolescents over 12 years imposed 1 g (for amoxicillin) 3 once a day, при необходимости – 4 once a day. The maximum daily dose - 6 g. For children 3 мес-12 лет – 25 mg / kg 3 once a day; в тяжелых случаях – 4 once a day; for children up to 3 Months: недоношенные и в перинатальном периоде – 25 mg / kg 2 once a day, в постперинатальном периоде – 25 mg / kg 3 once a day.

To prevention of post-surgical infections in operations, of less than 1 no,

during the induction of anesthesia in the injected dose 1 g / in. At longer operations - By 1 g every 6 hours within a day. With the high risk of infection, administration may be continued for several days.

At chronic renal failure shall adjust the dose and frequency of administration depending on QC: at QC more 30 ml / min dose adjustment is required; at CC 10-30 ml / min: внутрь – 250-500 mg / day every 12 no; в/в – 1 g, then 500 mg / in; at QC less 10 ml / min 1 g, then 500 mg / in / or 250-500 mg / day orally in a single step. For children, the dose should be reduced in the same manner.

Patients, located at gemodialize 250 mg or 500 mg orally in a single step or 500 mg / in, additionally 1 dose during dialysis and 1 dose at the end of dialysis.

Side effect

From the digestive system: nausea, vomiting, diarrhea, gastritis, stomatitis, glossitis, increase in liver transaminases, в единичных случаях – холестатическая желтуха, hepatitis, hepatic failure (most often in the elderly, Men, long-term therapy), psevdomembranoznыy and gemorragicheskiy colitis (also can develop after treatment), enterocolitis, черный “волосатый” язык, browning of tooth enamel.

From the side of hematopoiesis: reversible increase in prothrombin time and bleeding time, thrombocytopenia, thrombocytosis, eozinofilija, leukopenia, agranulocytosis, gemoliticheskaya anemia.

From the nervous system: dizziness, headache, hyperactivity, alarm, behavior change, convulsions.

Local reactions: в отдельных случаях – флебит в месте в/в введения.

Allergic reactions: hives, erythematous rash, редко – мультиформная экссудативная эритема, anaphylactic shock, angioedema, крайне редко – эксфолиативный дерматит, malignant exudative erythema (Stevens-Johnson syndrome), sensitization vasculitis, syndrome, similar to serum sickness, Acute generalized exanthematous pustullez.

Other: candidiasis, development of superinfection, interstitial nephritis, kristallurija, hematuria.

Contraindications

- Hypersensitivity (incl. cephalosporins etc.. beta-lactam antibiotics);

- Infectious mononucleosis (incl. the appearance of the rash morbilliform);

- Phenylketonuria;

- Jaundice episodes or abnormal liver function as a result of amoxycillin / clavulanic acid history;

- CC less than 30 ml / min (Pill 875 mg / 125 mg).

FROM caution: pregnancy, lactation, severe liver failure, gastrointestinal diseases (incl. a history of colitis, associated with the use of penicillins), chronic renal failure.

Pregnancy and lactation

Carefully: pregnancy, lactation.

There were cases of necrotizing enterocolitis in newborns, in pregnant women with premature rupture of membranes.

Cautions

In exchange treatment is necessary to monitor the state functions of blood, liver and kidneys.

To reduce the risk of side effects from the gastrointestinal tract should take the drug during meals.

Perhaps the development of superinfection due to growth insensitive to it microflora, which requires a corresponding change in antimicrobial therapy.

May give false positive results in the determination of glucose in urine. In this case, use glyukozoksidantny method of determining the concentration of glucose in the urine.

Once reconstituted suspension should be stored no more than 7 days in a refrigerator, but do not freeze.

Patients, with hypersensitivity to penicillins, possible cross-allergic reaction cephalosporin antibiotic.

There were cases of necrotizing enterocolitis in newborns, in pregnant women with premature rupture of membranes.

Since tablets contain the same amount of clavulanic acid (125 mg), should be considered, what 2 for tablets 250 mg (for amoxicillin) no equivalent 1 tablet of 500 mg (for amoxicillin).

Overdose

Symptoms: dysfunction of the gastrointestinal tract and water and electrolyte balance.

Treatment: symptomatic. Hemodialysis is effective.

Drug Interactions

Antacids, Glucosamine, laxative drugs, aminoglycosides slow down and reduce absorption; ascorbic acid increases absorption.

Bacteriostatic drugs (makrolidы, chloramphenicol, lincosamides, tetracikliny, sulfonamides) antagonize.

Improves the effectiveness of indirect anticoagulants (suppressing the intestinal microflora, It reduces the synthesis of vitamin K and prothrombin index). At the same time taking anticoagulants need to monitor the performance of blood clotting.

Reduces the effectiveness of oral contraceptives, drugs, during metabolism which is formed PABA, этинилэстрадиола – риск развития кровотечений “прорыва”.

Diuretic, allopurinol, phenylbutazone, NSAIDs, etc.. drugs, block tubular secretion, increase the concentration of amoxicillin (Clavulanic acid is derived mainly by glomerular filtration).

Allopurinol increases the risk of skin rashes.
