Pharmacological properties
Pharmacodynamics
Cefoxitin belongs to the antibiotics of the second generation cephalosporin group, has a wide spectrum of action. The agent is used for parenteral administration, exhibits a bactericidal effect, interfering with the synthesis of the cell wall of the microorganism.
The drug demonstrates activity against Staphylococcus aureus and Staphylococcus epidermidis (including strains producing and non-producing penicillinase). Shows high activity against gram-negative bacteria, such as Enterobacter spp., Haemophilus influenzae, Proteus mirabilis, Escherichia coli, Eikenella corrodens (strains that do not produce β-lactamase), Neisseria gonorrhoeae (including those producing and non-producing strains of penicillin), Morganella morganii, Providencia rettgeri, Providencia spp.
The antibiotic is active against the following anaerobic microorganisms: Clostridium spp., Peptostreptococcus spp., Peptococcus niger, Bacteroides spp. (including Bacteroides distasonis, Bacteroides thetaiotaomicron, Bacteroides fragilis, Bacteroides ovatus). Demonstrates resistance to β-lactamases.
Cefoxitin is inactive against various types of Pseudomonas spp., Many strains of Enterobacter cloacae (methicillin-resistant), Staphylococcus epidermidis and Staphylococcus aureus (methicillin-resistant strains), Listeria monocytogenes, Streptococcus pneumococcus haemolypto Most Enterococcus spp. (including Enterococcus faecalis) are resistant to the drug.
Pharmacokinetics
With intravenous administration, the maximum concentration (C max) of the active substance is observed at the end of the infusion, while after the administration of the drug at a dose of 1000 and 2000 mg C max is approximately equal to 110 and 244 μg / ml, respectively. The agent passes well into the joint cavity, pleural cavity, and is detected in antibacterial concentrations in bile. The drug binds to plasma proteins by 70–80%, the volume of distribution (V d) is 0.16 l / kg.
The half-life (T 1/2) is approximately 0.7-1.1 hours. In children, T 1/2 is: in newborns under the age of 7 days of life - approximately 5.6 hours; in infants aged 7-30 days - about 2.5 hours; at the age of 1-3 months - about 1.7 hours. The agent is excreted mainly unchanged (as a result of glomerular filtration - 85%, tubular secretion - 6%), in the form of inactive metabolites - from 0.2 to 5%.
In renal failure, T 1/2 of cefoxitin is about 5-6 hours.

The antibiotic Cefoxitin is recommended for the treatment of infectious and inflammatory diseases caused by microorganisms sensitive to the drug:
- respiratory tract infections;
- infections of bones and joints;
- infections of soft tissues and skin;
- infections of the urinary tract and pelvic organs;

In children, the maximum daily dose is 12,000 mg.
To prevent postoperative infections, children are prescribed the drug at a dose of 30–40 mg / kg 0.5–1 hours before the operation and every 6 hours for 1 day after the operation, however, the second and third doses are administered to newborns every 8–12 hours.
When performing a cesarean section, Cefoxitin is prescribed intravenously at the same time after clamping the umbilical cord at a dose of 2000 mg.
In patients with impaired renal excretory function, the first dose of the drug should be 1000–2000 mg; in the future, it is necessary to reduce the single dose and lengthen the intervals between injections.
The dosage regimen of Cefoxitin for impaired renal function, taking into account creatinine clearance (CC):
- CC 30-50 ml / min: every 8-12 hours, 1000-2000 mg;
- CC 10-29 ml / min: every 12-24 hours, 1000-2000 mg;
- CC 5-9 ml / min: every 12-24 hours, 500-1000 mg;
- CC below 5 ml / min: every 24–48 hours, 500–1000 mg.
Patients receiving hemodialysis treatment are advised to additionally use Cefoxitin at a dose of 1000–2000 mg after each procedure.
Children with impaired renal function should reduce the single dose and increase the interval between injections in accordance with the recommendations for adults with renal impairment.
Preparation of solutions depending on the method of administration:
- IV infusion: 500 or 1000 mg of the drug is diluted in 50 or 100 ml of solvent, respectively; solvents - solutions of sodium chloride 0.9% or dextrose 5%; the duration of the infusion - 30-60 minutes;

- others: increased severity of the course of myasthenia gravis.
Overdose
In case of an overdose of Cefoxitin, the severity of undesirable phenomena, except for allergic reactions, increases. Therapy is prescribed symptomatic.
special instructions
When treating newborns with cefoxitin, a preservative-free solvent is required. In children, the use of high doses of the drug is accompanied by an increase in the activity of asparagine aminotransferase and an increase in the incidence of eosinophilia.
The drug is not recommended for the treatment of meningitis.
If the Jaffe method is used to determine the level of creatinine, falsely increased serum concentrations of the latter in the blood are possible.
During the period of treatment with the drug, as well as 14-21 days after the completion of the course of therapy, there is a risk of developing diarrhea caused by Clostridium difficile (pseudomembranous colitis). If this complication occurs in mild cases, antibiotic treatment is canceled and ion exchange resins (colestipol, colestyramine) are used. In severe cases, measures are required to replace the loss of electrolytes, fluid, protein, as well as the use of vancomycin, metronidazole or bacitracin. Medicines that have an inhibitory effect on intestinal peristalsis are contraindicated.
Influence on the ability to drive vehicles and complex mechanisms
Patients driving vehicles or other complex and potentially dangerous machinery should be careful during therapy.

Pediatric use
The use of Cefoxitin in children is allowed according to the dosage regimen.
With impaired renal function
For patients with impaired renal function, the drug is prescribed with extreme caution.
In patients with impaired renal excretory function, the first dose of Cefoxitin should be 1000-2000 mg; in the future, it is necessary to reduce the single dose and lengthen the intervals between injections.
For patients with impaired renal function, the dosage regimen of the drug is set taking into account creatinine clearance (CC):

For violations of liver function
For patients with impaired hepatic function, Cefoxitin is prescribed with extreme caution.
Drug interactions
- other cephalosporins; aminoglycosides: the threat of nephrotoxicity is aggravated;
