Active substance: Amoxicillin
The drug forms
Coated tablets: oblong (0.5 g) or oval (1 g), biconvex, white to slightly yellowish color with notches on both sides.
Pharmachologic effect: antibacterial broad-spectrum.
Pharmacodynamics
Amoxicillin is a semisynthetic penicillin that has a bactericidal action. Mechanism of bactericidal action of amoxicillin is associated with damage to the cell membrane of bacteria in breeding stage. Amoxicillin specifically inhibits enzymes bacteria cell membranes (peptidoglycan), resulting in their death and lysis.
It is active against:
Gram positive aerobic bacteria - Bacillus anthracis, Corynebacterium spp. (Except Corynebacterium jeikeium), Enterococcus faecalis, Listeria monocytogenes, Streptococcus spp. (Including Streptococcus pneumoniae), Staphylococcus spp. (Except for strains producing penicillinase).
Gram negative aerobic bacteria -. Borrelia sp, Escherichia coli, Haemophilus spp, Helicobacter pylori, Leptospira spp, Neisseria spp, Proteus mirabilis, Salmonella spp, Shigella spp, Treponema spp, Campylobacter.......
Others - Chlamydia spp.
Anaerobic bacteria - Bacteroides melaninogenicus, Clostridium spp, Fusobacterium spp, Peptostreptococcus spp...
Not against:
Gram positive aerobic bacteria Staphylococcus (?-lactamase producing strains).
Gram-negative aerobic bacteria - Acinetobacter spp, Citrobacter spp, Enterobacter spp, Klebsiella spp, Moraxella catarrhalis, Proteus spp, Providencia spp, Pseudomonas spp, Serratia spp........
Anaerobic bacteria - Bacteroides spp.
Others - Mycoplasma spp, Rickettsia spp..
Pharmacokinetics
The absolute bioavailability of amoxicillin dose-dependent and ranges from 75 to 90%. The presence of food did not affect the drug absorption. As a result of oral administration of amoxicillin in a single dose of 500 mg of the drug concentration in plasma is 6-11 mg / l. After oral administration, Cmax in plasma achieved in 1-2 hours.
From 15 to 25% of amoxycillin binds to plasma proteins. The product quickly penetrates into the lung tissue, bronchial secretions, middle ear fluid, bile and urine. In the absence of inflammation of the meninges amoxicillin penetrates into the cerebrospinal fluid in minor amounts. When inflammation of the meninges of the drug concentration in CSF may be 20% of the plasma concentration. Amoxicillin crosses the placenta and is found in small quantities in breast milk.
Up to 25% of the administered dose is metabolized to form inactive penitsilloevoy acid.
About 60-80% of amoxicillin is excreted unchanged by the kidneys for 6-8 hours after ingestion. A small amount of the drug is excreted in the bile. T1 / 2 is 1-1.5 hours. In patients with renal disease T1 / 2 ranges from 5 to 20 hours. The drug is excreted by hemodialysis.
Testimony
Amoxicillin is indicated for infectious and inflammatory diseases caused by bacteria non-resistant to the drug:
- infectious diseases of the upper and lower respiratory tract and ENT-organs (tonsillitis, otitis media, pharyngitis, bronchitis, pneumonia, lung abscess);
- infectious diseases of the genitourinary system (urethritis, pyelonephritis, pyelitis, chronic bacterial prostatitis, epididymitis, cystitis, adnexitis, septic abortion, endometritis, etc.);
- Gastrointestinal infections: bacterial enteritis. You may need a combination therapy for infections caused by anaerobic microorganisms;
- infectious and inflammatory diseases of the biliary tract (cholangitis, cholecystitis);
- eradication of Helicobacter pylori (in combination with a proton pump inhibitor, clarithromycin or metronidazole);
- Skin and soft tissue infections;
- leptospirosis, listeriosis, Lyme disease (Lyme disease);
- endocarditis (including prevention of endocarditis during the dental procedures).
Contraindications
- hypersensitivity to penicillin and other ingredients;
- Hypersensitivity to other beta-lactam antibiotics such as cephalosporin, carbapenem (possibility of cross-reactions);
- Children under 3 years of age (for a given dosage form).
With caution the drug should be used in patients with impaired renal function; severe digestive disorders, accompanied by constant vomiting and diarrhea; allergic diathesis; asthma; hay fever; viral infections; with acute lymphoblastic leukemia; infectious mononucleosis (due to an increased risk of erythematous skin rashes); in children older than three years.
Pregnancy and breast-feeding
Animal studies have shown that amoxicillin does not have embryotoxic, teratogenic and mutagenic effects on the fetus. However, adequate and well-controlled studies on the use of amoxicillin in pregnant women has not been conducted, therefore the use of amoxicillin during pregnancy is possible only if the expected benefit to the mother outweighs the potential risk to the fetus.
The drug is excreted in breast milk, so the treatment of amoxicillin during lactation is necessary to resolve the issue of termination of breastfeeding, as may develop diarrhea and / or fungal colonization of the mucous membrane, as well as sensitization to beta-lactam antibiotics in nursing baby.

Interaction
May increase the absorption of digoxin time during therapy with Amoxicillin Sandoz®.
Probenecid decreases renal excretion of amoxicillin and amoxicillin concentration increases in bile and blood.
Avoid the simultaneous use of amoxicillin and other bacteriostatic drugs (macrolides, tetracyclines, sulfonamides, chloramphenicol) because of the possibility of antagonism. With simultaneous use of aminoglycosides and amoxicillin may develop sinnergicheskogo effect.
Not recommended simultaneous use of amoxicillin and disulfiram.
With simultaneous use of amoxicillin and methotrexate may increase the toxicity of the first, probably because of the competitive inhibition of renal tubular secretion of methotrexate amoxicillin.
Antacids, glucosamine, laxatives, drugs, food, aminoglycosides slow down and reduce the absorption, ascorbic acid increases the absorption of amoxicillin.
It improves the effectiveness of indirect anticoagulants (suppressing the intestinal microflora, reduces the synthesis of vitamin K and prothrombin index); estrogensoderzhaschih reduces the effectiveness of oral contraceptives; drugs in the metabolism that produce para-aminobenzoic acid (PABA), products of ethinyl estradiol - the risk of "breakthrough" bleeding.
Diuretics, allopurinol, oxyphenbutazone, phenylbutazone, nonsteroidal anti-inflammatory drugs and other drugs that block tubular secretion, increase the concentration of amoxicillin in the blood.
Allopurinol increases the risk of skin rash.

Treatment: reception activated carbon, symptomatic therapy, correction of violations of water-electrolyte balance, hemodialysis possible.
Special instructions
Before prescribing Amoxicillin Sandoz® make sure that the strains of microorganisms that cause infectious disease, are sensitive to the drug.
In severe infectious and inflammatory gastrointestinal processes involving prolonged diarrhea or nausea, it is recommended not to take Amoxicillin Sandoz® inside because of possible low absorption of the drug.
In the treatment of mild diarrhea on the background of a course of treatment should be avoided antidiarrhoeal drugs that reduce intestinal motility; You can use kaolin or attapulgitsoderzhaschie antidiarrheal drugs. In severe diarrhea should consult a doctor.
To exclude the development of pseudomembranous colitis (caused by Clostridium difficile) With the development of severe persistent diarrhea. In this case, Sandoz® Amoxicillin should be discontinued and appropriate treatment. Thus drugs that slow down the motility of the gastrointestinal tract, are contraindicated.
In exchange treatment is necessary to monitor the state functions of blood, liver and kidneys.
Perhaps the development of superinfection due to growth insensitive to it microflora, which requires a corresponding change in antibiotic therapy.
In patients with increased sensitivity to penicillins, possible allergic cross-reactivity with other beta-lactam antibiotics.
Treatment continues for sure 48-72 hours after the disappearance of clinical signs of disease.
With simultaneous use of oral contraceptives and estrogensoderjath amoxicillin should be possible to use other or additional contraceptive methods.
Amoxicillin Sandoz® not recommended for the treatment of acute respiratory viral infections due to low efficiency.
Particular caution is recommended that the patients with atopic diathesis or bronchial asthma, gastrointestinal diseases in history (in particular, colitis caused by treatment with antibiotics).
Chronic administration of Amoxicillin Sandoz® should appoint a Nystatin, Levorinum or other antifungals.
During treatment is not recommended to use ethanol.
Application Amoxicillin Sandoz® no effect on the results of enzymatic analysis glycosuria, but there may be false positive urine tests for glucose.
While receiving the drug Amoxicillin Sandoz® recommended to drink plenty of fluids to prevent the formation of crystals in the urine of amoxicillin.
Effects on ability to drive and perform other activities that require concentration and speed of psychomotor reactions
