Resistant to the medicinal product: Streptococcus group D, Listeria and methicillin-resistant staphylococci.
Absorption. Five minutes after a single intravenous injection of 1 g of cefotaxime, its serum concentration is 100 μg/ml. After intramuscular administration of cefotaxime in the same dose, the maximum concentration in the blood is reached after 0.5 hours and is 24 μg/ml. The bactericidal concentration in the blood persists for 12 hours.
Distribution. Plasma protein binding is on average 25-40 %. Cefotaxime penetrates well into tissues and body fluids. It is determined in effective concentrations in pleural, peritoneal, synovial fluids. Penetrates the blood-brain barrier. Biotransformed with the formation of the active metabolite.
Excretion. Approximately 60-70 % of the administered dose of the medicinal product is excreted in the urine unchanged, and the rest is excreted in the form of metabolites. Partially excreted in the bile. The half-life of the medicinal product is 1 hour for intravenous administration and 1-1.5 hours for intramuscular administration. In renal failure and in elderly patients, the half-life of the medicinal product increases by about 2 times. In newborns, the half-life of the medicinal product is from 0.75 to 1.5 hours, and in premature infants - from 1.4 to 6.4 hours.
Infections caused by drug-sensitive microorganisms:
- infections of ENT organs (sore throat, otitis);
- respiratory tract infections (bronchitis, pneumonia, pleurisy, abscesses);
- urogenital infections;
- septicemia, bacteremia;
- intra-abdominal infections (including peritonitis);
- skin and soft tissue infections;
- bone and joint infections;
- meningitis (with the exception of listeria) and other infections of the central nervous system.
Prevention of infections after surgical operations on the digestive tract, urological and obstetric-gynecological operations.
Hypersensitivity to cephalosporin antibiotics and to other beta-lactam antibiotics, hypersensitivity to lidocaine (intramuscular injection); bleeding, history of enterocolitis (especially nonspecific ulcerative colitis).
AV-blockade without an established pacemaker, severe heart failure.
Interaction with other medicinal products and other forms of interaction
Concomitant use with nephrotoxic medicinal products (aminoglycosides) and potent diuretics (ethacrynic acid, furosemide), colistin, polymyxin, the risk of developing renal failure increases.
During treatment with cefotaxime, the effectiveness of oral contraceptives may decrease, so during this period it is necessary to use additional contraception. Cefotaxime should not be used in conjunction with bacteriostatic antibiotics (e.g. tetracyclines, erythromycin and chloramphenicol) as an antagonistic effect is possible.
In combination therapy, cefotaxime solutions should not be mixed with aminoglycoside solutions - they must be administered separately.
Concomitant use of nifedipine increases the bioavailability of cefotaxime by 70 %.
Probenecid blocks the tubular secretion of cefotaxime and prolongs its half-life.
Cefotaxime should not be used with lidocaine:
- with intravenous administration;
- children under 30 months;
- patients with a history of hypersensitivity to lidocaine;
- patients with heart block.
Special warnings and precautions for use.
Prescribe with caution in case of impaired renal or liver function, with a history of hypersensitivity to penicillins. In case of impaired renal function, the dose of the medicinal product should be reduced taking into account the severity of renal failure and the sensitivity of the pathogen. With long-term use of the medicinal product, 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 medicinal product, it is possible to develop a false-positive Coombs test.
Anaphylactic reactions. The use of cephalosporins requires clarification of the allergic history (allergic diathesis, hypersensitivity reactions to beta-lactam antibiotics). If the patient develops a hypersensitivity reaction, treatment should be discontinued. The use of cefotaxime is strictly contraindicated in patients with a history of an immediate hypersensitivity reaction to cephalosporins. In case of any doubt, the presence of a doctor at the first administration of the medicinal product is mandatory due to the possible development of an anaphylactic reaction. Known cross-allergy between cephalosporins and penicillins, which occurs in 5-10% of cases. In patients with a history of penicillin allergy, the medicinal product should be used with extreme caution.
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: the medicinal product should be discontinued immediately and adequate therapy should be prescribed, including oral vancomycin or metronidazole. he combination of the use of cefotaxime with nephrotoxic medicinal products requires monitoring of renal function, the use of more than 10 days - monitoring of blood composition. Elderly and debilitated patients should be prescribed vitamin K (prevention of hypocoagulation).
As with other broad-spectrum antibiotics, long-term use can lead to an increased growth of insensitive microorganisms, which requires discontinuation of treatment. If superinfection occurs during treatment, antimicrobial therapy should be used. False-positive results can be obtained when urine glucose is measured by the recovery method. An enzyme test should be used to prevent this.
During treatment, alcohol should not be consumed, since effects similar to the action of disulfiram are possible (flushing of the face, cramps in the abdomen and stomach area, nausea, vomiting, headache, lowering blood pressure, tachycardia, difficulty breathing).
1 g of powder for solution for injection contains 2.2 mmol (50.5 mg) sodium. The amount of sodium at the maximum daily dose exceeds 8.7 mmol (200 mg). This should be taken into account in patients on a sodium diet.

The use of the medicinal product during pregnancy is contraindicated.
Breast-feeding should be discontinued during treatment with the medicinal product.
