Clinico-pharmacological group: Antibiotic penicillin group of broad-spectrum, collapsing penicillinase.

Pharmacological action

Broad-spectrum antibiotic of semisynthetic penicillins. Effective bactericidal. Inhibits transpeptidase, violates the synthesis of peptidoglycan (the reference polymer cell wall) in the period of division and growth, causes lysis of bacteria. Acid-resistant. Active against aerobic gram-positive bacteria: Staphylococcus spp. (With the exception of strains producing penicillinase), Streptococcus spp. and aerobic gram-negative bacteria: Neisseria gonorrhoeae, Neisseria meningitidis, Bacillus anthracis, Listeria monocytogenes, Helicobacter pylori, Klebsiella spp. Microorganisms, penicillinase-producing, resistant to the action of amoxicillin. The action develops within 15-30 min after injection and lasts 8 hours

Pharmacokinetics

Absorption

After oral amoxicillin quickly and almost completely (93%) absorbed from the gastrointestinal tract. Eating does not affect the absorption of the drug, is not destroyed in the acidic environment of the stomach. Cmax of the active substance in the plasma observed after 1-2 h. When administered at a dose of 125 mg and 250 mg Cmax plasma levels of 1.5-3 mg / ml and 3.5-5 mg / ml, respectively.

Distribution

It has a large volume of distribution: in high concentrations found in plasma, sputum, bronchial secretion (purulent bronchial secretion in the distribution of the poor), pleural and peritoneal fluid, urine, contents of skin blisters, tissue of the lung, intestinal mucosa, the female genital organs, prostate gland, middle ear fluid, bone, fat tissue, gall bladder (with normal liver function), fetal tissues.

With increasing doses of 2 times the concentration also increased by 2 times. The concentration in bile exceeds the concentration in plasma 2-4 times. In the amniotic fluid and umbilical cord vessels concentrations of amoxicillin - 25-30% of the level in plasma in pregnant women. Poorly crosses the BBB, the inflammation of the meninges (meningitis) concentration in cerebrospinal fluid - about 20%. Binding to plasma proteins - 17%. In small amounts excreted in breast milk.

Metabolism

Amoxicillin partly metabolized to form inactive metabolites.

Withdrawal

T1 / 2 of amoxicillin is 1-1.5 hours Amoxicillin output by 50-70% in the urine in unchanged form by tubular excretion (80%) and glomerular filtration rate (20%), with bile - 10-20%. Premature, Newborn and children under 6 months - 3-4 hours

Pharmacokinetics in special clinical situations

In preterm, newborns and children under 6 months of T1 / 2 of 3-4 h. In renal dysfunction (CC ≤ 15 mL / min) T1 / 2 of amoxicillin increased to 8.5 h. Amoxicillin is removed during hemodialysis.

Dosage regimen

The drug, taken orally, either before or after meals.

Dosage regimen set individually, taking into account the severity of the disease, susceptible to the drug, the patient's age.

Children aged 5 to 10 years prescribed 250 mg 3 times / day, at the age of 2 to 5 years - 125 mg 3 times / day, up to 2 years - 20 mg / kg / day in 3 divided doses. The treatment course - 5-12 days.

Children aged under 5 years of drug administered in the form of suspension. For the treatment of acute uncomplicated gonorrhea drug administered in a dose of 3 g once, in the treatment of women should receive a second dose given.

In acute infectious diseases of the digestive tract (paratyphoid fever, typhoid fever), and biliary tract, gynecological infectious diseases of adults appoint 1.5-2 g 3 times / day or 1-1.5 g 4 times / day.

In leptospirosis adults appoint 500-750 mg 4 times / day for 6-12 days.

When salmonellonositelstve adults - 1.5-2 g 3 times / day for 2-4 weeks. For the prevention of endocarditis with small surgical interventions for adults prescribed a dose of 3-4 g for 1 h before the procedure.

If you want to be reappointed after a dose of 8-9 h. In children, the dose is reduced by half. Patients with impaired renal function (QC from 15 to 40 ml / min) interval between doses increased to 12 hours in the terminal stage of chronic renal failure (CC <10 ml / min) Amosina dose should be reduced by 15-50%, or increase the interval between doses up to 24 h, when anuria - the maximum dose of 2 g / day.

Terms preparation of the suspension

Single-dose pack

On the part of the digestive system: dysbacteriosis, change in taste, vomiting, nausea, diarrhea, stomatitis, glossitis, abnormal liver function, a moderate increase in liver transaminases; rarely - pseudomembranous enterocolitis.

From the central nervous system and peripheral nervous system: agitation, anxiety, insomnia, ataxia, confusion, behavioral change, depression, peripheral neuropathy, headache, dizziness, convulsive reaction.

Children under 3 years (for tablets and capsules).

Precautions should be prescribed the drug during pregnancy, renal insufficiency, as well as guidance on the history of bleeding.

Pregnancy and lactation

Use of the drug during pregnancy is possible only in cases where the intended use of therapy to the mother outweighs the potential risk to the fetus.

Use during lactation is contraindicated. If necessary, use during lactation should stop breastfeeding.

Application for violations of liver function

Contraindicated in hepatic failure.

Application for violations of renal function

Patients with impaired renal function (QA - 15-40 ml / min) interval between doses increased to 12 hours in the terminal stage of chronic renal failure (CC <10 ml / min) Amosina dose should be reduced by 15-50%, or increase the interval between doses up to 24 h, when anuria - the maximum dose of 2 g / day.

Cautions

In the course of treatment Amosinom need to monitor the state functions of blood, liver and kidneys. Perhaps the development of superinfection due to growth insensitive to amoxicillin microflora, which requires a corresponding change in antimicrobial therapy.

When treating patients with bacteremia rarely develops bacteriolysis reaction (reaction Jarisch-Herxheimer). Patients who have an increased sensitivity to penicillin, may be cross-allergic reactions to cephalosporin antibiotics.

In the treatment of mild diarrhea during treatment Amosina avoid appointment antidiarrhoeal drugs that reduce intestinal motility; can use kaolin or attapulgitsoderzhaschie antidiarrhoeal funds.

Patients with severe diarrhea should make a differential diagnosis and assign the appropriate therapy.

Treatment should be continued even 48-72 hours after the disappearance of clinical signs of disease.

With simultaneous use of oral contraceptives estrogensoderzhaschih and amoxicillin should, if possible, to use additional methods of contraception.

Overdose

Symptoms: nausea, vomiting, diarrhea, disruption of water and electrolyte balance (as a consequence of vomiting and diarrhea). Treatment: gastric lavage, activated charcoal, saline laxatives, measures aimed at maintaining water and electrolyte balance; hemodialysis.

Drug Interactions

Antacids, glucosamine, laxatives, diet, aminoglycoside antibiotics, while applying slow and reduce the absorption of amoxicillin, ascorbic acid - increases its absorption. Bactericidal antibiotics (including aminoglycosides, cephalosporins, cycloserine, vancomycin, rifampicin) often synergy with amoxicillin; bacteriostatic drugs (macrolides, chloramphenicol, Lincosamides, tetracyclines, sulfonamides) - antagonism.

Amoxicillin, while the application increases 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, ethinyl estradiol (the risk of intermenstrual bleeding), as well as medicines, which are formed during metabolism of para-aminobenzoic acid . Diuretics, allopurinol, oxyphenbutazone, fenilbutazon, NSAIDs and drugs that block tubular secretion, while reducing the use of Amosinom tubular secretion, increase the concentration of amoxicillin.

With simultaneous application Amosina with allopurinol increases the risk of developing skin rashes.

Amoxicillin with simultaneous application reduces clearance and increases the toxicity of methotrexate. Amoxicillin, while the application increases the absorption of digoxin.
