Intravenously (intravenously) or intramuscularly (in / m). The dose and route of administration depend on the sensitivity of the pathogens, the severity of the infection, the state of kidney function and the general condition of the patient.
Intravenous administration It is recommended for patients with severe or life-threatening infections, especially when there is a risk of septic shock.
Preparation of a solution for intravenous administration
The drug is dissolved in 5 or 10 ml of sterile water for injection, 5% dextrose solution and 0.9% solution of sodium chloride for injection as indicated in the table below and administered within 3-5 minutes either directly into a vein or into an intravenous system through which a compatible solution for the intravenous introduction.
Preparation of a solution for intravenous infusion
The prepared solution (see above) is transferred to an infusion vessel with other compatible solutions for intravenous infusions (see below) and administered for at least 30 minutes.
| Volume of dilution solution (ml) | The approximate volume of the solution obtained (ml) | The approximate concentration of cefepime (mg / ml) |
Intravenous introduction: | | | |
500 mg / bottle | 5 | 5,7 | 90 |
1 g / bottle | 10 | 11,4 | 90 |
Drug solutions with a concentration of 1-40 mg / ml are compatible with the following parenteral solutions: 0.9% solution of sodium chloride for injection; 5% or 10% dextrose solution for injection.
Intramuscular injection: the dose to 1 g (volume <3.1 ml) can be administered as a single injection. The maximum dose (2 g / 6.2 ml) should be given as two injections in different places.
Preparation of solution for intramuscular injection
The preparation is dissolved in sterile water for injection, 5% dextrose solution or 0.9% solution of sodium chloride for injection, 0.5% or 1% lidocaine solution, as indicated in the table below.
| Volume of dilution solution (ml) | The approximate volume of the solution obtained (ml) | The approximate concentration of cefepime (mg / ml) |
Intramuscular introduction: | | | |
500 mg / bottle | 1,5 | 2,2 | 230 |
1 g / bottle | 3,0 | 4,4 | 230 |
Storage of solutions for intravenous and intramuscular administration
Only freshly prepared solution is used.
As with all solutions for parenteral administration, before preparation, the prepared solutions of the preparation should be checked for the absence of visible mechanical inclusions. Otherwise, it is forbidden to use the prepared solution.
Dosing regimens of cefepime depending on the disease, body weight and age of the patient
The dose for children should not exceed the maximum recommended dose for adults (2 g IV, every 8 hours). The experience of intramuscular administration of the drug to children is limited.
Adults and children weighing more than 40 kg with normal kidney function
Urinary tract infections of mild and moderate severity: | 500 mg - 1 g IV or IM | every 12 hours |
Other infections of mild to moderate severity: | 1 g IV or IM | every 12 hours |
Severe infections: | 2 g IV | every 12 hours |
Very serious and life-threatening infections: | 2 g IV | every 8 hours |
The usual duration of treatment is 7-10 days; severe infections may require longer treatment.
In the case of treatment of febrile neutropenia, the usual duration of treatment is 7 days or until neutropenia disappears.
Prevention of infections during surgical operations
60 minutes prior to the beginning of the surgical operation, 2 g of the drug are administered intravenously in the form of infusion, for 30 minutes. Immediately after the end of the infusion, the patient is administered 500 mg of metronidazole intravenously. A solution of metronidazole is prepared according to the instructions for its use.application. Due to the pharmaceutical incompatibility of metronidazole and cefepime, they should not be mixed in a single vessel. Infusion system before the introduction of metronidazole should be washed. During prolonged (more than 12 hours) surgical operations 12 hours after the first dose, repeated administration of cefepime is recommended in the same dose with the subsequent administration of metronidazole.
Children from 2 months with a body weight of up to 40 kg
For urinary tract infections, skin and soft tissue infections, pneumonia, the recommended dose is 50 mg / kg every 12 hours for 10 days. In case of severe infections - every 8 hours.
Patients with febrile neutropenia, septicemia, bacterial meningitis should be administered 50 mg / kg every 8 hours for 7-10 days.
Patients with impaired renal function
Patients with impaired renal function require adjustment of the dosage of cefepime to compensate for the reduced rate of excretion in the urine. The dosage regimen depends on the degree of impaired renal function, the severity of infection and the sensitivity of microorganisms. With weak or moderate disturbances of kidney function, the initial dose of the drug is the same as with normal kidney function.
Recommended maintenance doses of cefepime depending on the creatinine clearance are presented in the table below.
The creatinine clearance for men is calculated from the serum creatinine concentration, according to the following formula:
Creatinine clearance (ml / min) = Body weight (kg) x (140 - age) / [72 x serum creatinine (mg / dL)]
Creatinine clearance for women is calculated by the same formula using the factor 0.85.
Creatinine clearance (ml / min) | Recommended maintenance doses |
| (Usual dose, dose adjustment is not required) |
>60 | 2 grams every 8 hours | 2 grams every 12 hours | 1 g every 12 hours | 500 mg every 12 hours |
30-60 | 2 grams every 12 hours | 2 grams every 24 hours | 1 g every 24 hours | 500 mg every 24 hours |
11-29 | 2 grams every 24 hours | 1 g every 24 hours | 500 mg every 24 hours | 500 mg every 24 hours |
≤11 | 1 g every 24 hours | 500 mg every 24 hours | 250 mg every 24 hours | 250 mg every 24 hours |
With continuous ambulatory peritoneal dialysis | 2 grams every 48 hours | 2 grams every 48 hours | 1 g every 48 hours | 500 mg every 48 hours |
Patients on hemodialysis * | 500 mg every 24 hours | 500 mg every 24 hours | 500 mg every 24 hours | 500 mg every 24 hours |
* For patients on hemodialysis, it is recommended: 1 g on the first day of treatment and then at 500 mg every 24 hours for all infections, except for ferile neutropenia, where the dose is 1 g every 24 hours.In days of hemodialysis, the drug should be administered at the end of hemodialysis. If possible, the drug should be administered at the same time every day.
With hemodialysis within 3 hours, approximately 68% of the administered dose is removed from the body.
Children with impaired renal function
Children with impaired renal function are recommended to reduce the dose or increase the interval between administrations, as indicated in the table above.
Creatinine clearance is calculated by the following formulas:
Creatinine clearance (ml / min / 1.732) = 0.55 x height (cm) / serum creatinine (mg / dl)
or
Creatinine clearance (ml / min / 1.732) = [0.52 x height (cm) / serum creatinine (mg / dl)] - 3.6.
Patients with impaired hepatic function
Dose adjustments for patients with impaired liver function are not required.
