Amoxil - General information

Amoxicillin - semisynthetic aminopenicillin, has a bactericidal effect with the optimum spectrum of antimicrobial activity, is not sensitive to mikoroorganizmam that can produce penicillinase.

Amoxicillin / clavulanate - penicillin protected with high efficiency of action against many bacteria, the advantage is the presence of clavulanic acid, which makes the drug-resistant lactamases (penicillinase)? Clavulanic acid is a competitive irreversible inhibition of beta-lactamase, which allows the same to reduce the phenomenon of cross-resistance to antimicrobials.

It has an active effect on many organisms, including:
Gram (+) aerobes: Bacillus anthracis, Enterococcus (faecalis, faecium), Listeria monocytogenes, types of Corynebacterium, Nocardia asteroides, Staph. aureus, coagulase (-) staphylococci (including Staph epidermidis.), Str. agalactiae, Str. pneumoniae, Str. pyogenes, kinds Str. viridans;
gram (+) anaerobes: Clostridium, peptococci, Peptostreptococcus species;
gram (-) aerobes: Bordetella pertussis, types of Brucella, E. coli, Gardnerella vag, Haemophilus influenzae, Helicobacter pylori, Klebsiella, Legionella, Moraxella catarrhalis (Branhamella catarrhalis), N. gonorrhoeae, N. meningitidis, Pasteurella multocida, Proteus mirabilis. , Pr. vulgaris, species of Salmonella, types of Shigella, Vibrio vibroion, Yersinia enterocolitica;
gram (-) anaerobes: species of Bacteroides (including Bacteroides fragilis), species of Fusobacterium;
other bacteria: Borrelia burgdorferi, Chlamydia, Leptospira icterohaemorrhagiae, pale treponema.

What are antibiotics?

Amoxicillin unprotected no effect on the bacteria that produce beta-lactamase, which makes certain bacteria insensitive to amoxicillin alone.
Almost immediately absorbed from the gastrointestinal tract, the mean Cmax - 30-45 min. Bioavailability is 90% of the drug when administered orally. The period T? equal to 60-90 minutes. Communication with blood proteins and minor amounts of up to 20% for amoxycillin and 30% for clavulanic acid. The drug is metabolized in the liver. Amoxil is distributed fairly active in the skin, fat, muscle tissues of the abdominal cavity, hepatobiliary system, and as defined in the synovial, peritoneal fluid. Elimination occurs via the kidneys. Preparation derived predominantly in unmodified form in urine during the first six hours.

Amoxil/Amoxicillin Side effects

Against the background of the drug may develop the following adverse reactions:
Changes in the gastrointestinal tract - nausea, vomiting, frequent stools, pesevdomembranozny or hemorrhagic colitis, often in the background of the tablet form of the drug.
Changes in the liver - increase in liver function tests and enzymes, cholestasis with symptoms of jaundice and inflammation of liver tissue.
Changes in the central nervous system - dizziness, headaches, convulsive readiness.
Allergic reaction - skin rash, urticaria, rarely severe toksikoallergicheskie reaction in the form of Syndrome Stevens - Johnson syndrome and Lyell.

Changes in the urinary system - crystalluria, nephritis interstetsialny.

Individual intolerance to the drug or its components. The intolerance to penicillins, cephalosporins, carbapenems. Lactation. Care should be taken during pregnancy.


Caution is used during pregnancy, especially during the first trimester. When lactation in case of treatment Amoxil necessary to abandon breastfeeding during treatment.

Interaction with other drugs:
Aminoglycosides and Amoxil not apply at the same time, because possible mutual inactivation of the active ingredients.
Tetracyclines, macrolides, chloramphenicol act as antagonists with respect to amoxycillin.
Probenecid, NSAIDs, phenylbutazone, diuretics, allopurinol reduced Amoxil excretion in the urine, which increases the risk of adverse reactions.
Allopurinol to background Amoxil increases the likelihood of allergic reactions.
Amoxil reduces the bioavailability of COCs, thereby reducing their pharmacological effects.

Digoxin Amoxil absorbance changes upwards and as a consequence increases its therapeutic effect.
Acenocoumarol or warfarin on the background of Amoxil may alter prothrombin time at high risk of bleeding.
Ascorbic acid Amoxil increases absorption in the intestine.
Antacids, laxatives, food, aminoglycosides, glucosamine reduces the bioavailability of Amoxil.
Amoxil enhances the toxic effects of methotrexate.


In the case of drug overdose observed with gastrointestinal disturbances, changes in fluid and electrolyte balance. Symptomatic treatment with a focus on restoration of electrolyte abnormalities. Rarely observed symptoms of renal failure associated with impaired renal parenchyma as a result of crystallization of amoxicillin. For the elimination of the drug from the bloodstream applied hemodialysis.
