Pharmacological properties.

Pharmacodynamics

Cefotaxime-BCHPZ is a semi-synthetic antibiotic of the third generation cephalosporins group, a wide spectrum of action, for parenteral administration. The drug is effective against many gram-positive and is highly active against gram-negative bacteria. It acts bactericidal on bacterial strains resistant to penicillin, aminoglycosides, sulfonamides. The antimicrobial mechanism of cefotaxime-BCPP is associated with inhibition of the activity of the transpeptidase enzyme, peptidoglycan blockade, and mucopeptide formation of the cell wall of microorganisms. The drug is resistant to four of the five beta-lactamases of gram-negative bacteria and penicillin staphylococci. It is active against Staphylococcus aureus, Staphylococcus epidermidis, some strains of Enterococcus spp., Streptococcus pneumoniae (especially Diplococcus pneumoniae), Streptococcus pyogenes (beta-hemolytic streptococci group A), Streptococcus bacillus, Streptococcus bacillus Bacterida bacillidae, Streptococcus bacillus, Bacteris bacillidae, diphtheriae, Erysipelothrix insidiosa, Eubacterium, Enterobacter aerogenes, Enterobacter cloacae, Escherichia coli, Haemophilus influenzae, including ampicillin-resistant strains, Haemophilus parainfluenzae, Klebsiella morinella, Neissa moriella , Propionibacterium, Proteus mirabilis, Proteus vulgaris, Proteus inconstans, Serratia spp., Veillonella, Yer sinia, Bordetella pertussis, Moraxella, Aeromonas hydrophilia, Fusobacterium, Bacteroides spp., Clostridium species, Peptostreptococcus species, Peptococus spp.

Affects some strains of Pseudomonas aeruginosa, Acinetobacter, Helicobacter pylori, Bacteroides fragilis, Clostridiun difficile. May affect multi-resistant strains that are resistant to penicillins, first-generation cephalosporins, aminoglycosides. The drug is less active against gram-positive cocci than cephalosporins of I-II generations.

To the action of the drug resistant group D streptococci, Listeria spp. and methicillin-resistant staphylococci.

Pharmacokinetics

The maximum concentration in the blood after intramuscular administration of the drug in doses of 500 mg and 1000 mg is observed 30 minutes after administration and is 11 μg / ml and 21 μg / ml, respectively. 5 minutes after intravenous administration of 500 mg, 1000 mg or 2000 mg, the maximum concentration in the blood is 39, 100, 214 μg / ml, respectively. In blood, the drug is 25-40% bound to blood proteins. The bactericidal concentration in the blood lasts more than 12 hours. The drug penetrates well into tissues (creates an effective concentration in the myocardium, bone tissue, gall bladder, skin, soft tissues), body fluids (determined in effective concentrations in the cerebrospinal, pericardial, pleural, peritoneal, synovial fluids), passes through the placenta, penetrates into breast milk. Cefotaxime-BCHPZ is excreted in a significant amount with urine (90%) (unchanged, about 60–70% and in the form of active metabolites, about 20–30%, of which 15–25% is the main metabolite - deacetylcefotaxime, which has antimicrobial activity). The half-life with intravenous administration is 1 hour, with intramuscular administration - 1-1.5 hours. With repeated intravenous doses of 1000 mg every 6 hours for 14 days, cumulation is not observed. In infants, the half-life is 0.75–1.5 hours, in premature infants — from 1.4 to 6.4 hours, in patients older than 80 years and with renal failure, the half-life of the drug increases by approximately 2 times.

Clinical characteristics.

Indications.

Infections caused by microorganisms sensitive to the action of the drug:

  • infections of ENT organs (tonsillitis, otitis media);
  • respiratory tract infections (bronchitis, pneumonia, pleurisy, abscesses);
  • urinary tract infections;
  • septicemia, bacteremia;
  • intra-abdominal infections (including peritonitis);
  • infections of the skin and soft tissues;
  • infections of bones and joints;
  • meningitis (except listeriosis) and other central nervous system infections;
  • prevention of infections after surgery on the digestive tract, urological and obstetric-gynecological operations.

Contraindications

Hypersensitivity to cephalosporin antibiotics and other beta-lactam antibiotics, hypersensitivity to lidocaine (intramuscular injection); history of bleeding, history of enterocolitis (especially ulcerative colitis).

AV blockade without an established heart rate driver, severe heart failure.

Interaction with other drugs and other types of interactions.

With nephrotoxic drugs (aminoglycosides) and potent diuretics (ethacrylic acid, furosemide), colistin, polymyxin, the risk of developing renal failure increases.

With bacteriostatic antibiotics (e.g. tetracyclines, erythromycin and chloramphenicol), an antagonistic effect is possible.

With aminoglycoside solutions should not be mixed, they must be entered separately.

With nifedipine, the bioavailability of cefotaxime is increased by 70%.

With probenecid, tubular secretion of cefotaxime is blocked and its half-life is prolonged.

Do not use cefotaxime with lidocaine:

  • with intravenous administration;
  • children under 30 months;
  • patients with a history of hypersensitivity to lidocaine;
  • heart block patients.

During treatment with cefotaxime, the effectiveness of oral contraceptives may decrease, therefore, additional contraception must be used during this period.

Features of the application.

With caution, prescribe the drug for impaired renal and hepatic function; in case of impaired renal function, the dose should be reduced taking into account the severity of renal failure and the sensitivity of the pathogen.

With prolonged use of the drug, kidney function should be monitored, and dysbiosis should be prevented. It is advisable to regularly monitor the cellular composition of peripheral blood, liver function. When using the drug, the development of a false positive Coombs test is possible.

Anaphylactic reactions. The use of cephalosporins requires clarification of the allergological history (allergic diathesis, hypersensitivity reactions to beta-lactam antibiotics). If a patient develops a hypersensitivity reaction, treatment should be discontinued. The use of cefotaxime is strictly contraindicated in patients with a history of immediate hypersensitivity reactions to cephalosporins. In case of any doubt, the presence of a doctor at the first injection of the drug is necessary due to the possible development of an anaphylactic reaction. A cross-allergic reaction between cephalosporins and penicillins is known, which occurs in 5–10% of cases.

Pseudomembranous colitis. In the first weeks of treatment, pseudomembranous colitis may occur, manifested by severe prolonged diarrhea. The diagnosis is confirmed by colonoscopy and / or histological examination. These complications are regarded as very serious: immediately stop administering the drug and prescribe adequate therapy, including oral administration of vancomycin or metronidazole.

The combination of cefatoxime with nephrotoxic drugs requires monitoring of renal function, the use of more than 10 days - monitoring of blood composition. For elderly and debilitated patients, prescribe vitamin K (prevention of hypocoagulation).

Each gram of the drug contains approximately 0.048 g of sodium, which should be considered for patients on a diet with a controlled sodium content.

As with other broad-spectrum antibiotics, long-term use can lead to increased growth of insensitive microorganisms, which requires discontinuation of treatment. If superinfection occurs during treatment, antimicrobial therapy should be used.

When determining the level of glucose in the urine by the recovery method, false-positive results can be obtained. An enzyme test should be used to prevent this.

During treatment, alcohol cannot be used, since effects similar to disulfiram are possible (facial flushing, cramping in the abdomen and stomach, nausea, vomiting, headache, lowering blood pressure, tachycardia, difficulty breathing).

When using lidocaine as a solvent for intramuscular injection, a skin test for lidocaine tolerance should be done before injection.

Incompatibility.

It should not be administered in the same container with other drugs, except for the solutions indicated in the instructions.

Use during pregnancy or lactation.

The use of the drug during pregnancy is contraindicated.

For the period of treatment should stop breast-feeding.

The ability to influence the reaction rate when driving vehicles or other mechanisms.

Due to the possibility of adverse reactions from the nervous system, you should avoid driving or working with other mechanisms during the treatment period.

Dosage and administration.

Before using the drug, it is necessary to conduct skin tests for tolerance.
