Use in patients with impaired renal function: with a CC of 55 ml / min or more, or with a plasma creatine content of 1.5 mg% or less, a full dose can be administered. With a CC of 54-35 ml / min or with a plasma creatinine content of 3-1.6 mg%, the full dose can be used, but the intervals between injections should be increased to 8 hours. With a CC of 34-11 ml / min or with a creatinine content of 4, 5-3.1 mg% -1 / 2 doses at 12-hour intervals Patients with CC 10 ml / min or less, or with a creatinine content in plasma of 4.6 mg% or more than 1/2 average dose every 18-24 hours.
Use in children: average daily dose for children 20-50 ml / kg in severe infections, the dose can be increased to 100 mg / w / day. The multiplicity of reference is 3-4 times a day.
Use in children with impaired renal function: in children with impaired renal function, correction of the dosage regimen is carried out depending on the QC values. With CC 70-40 ml / min – 60% of the average daily dose and excreted after 12 hours. With CC 40-20 ml / min – 25% of the average daily dose with an interval of 12 hours. Children with CC 5-20 ml / min – 10% of the average daily dose every 24 hours. All recommended doses are administered after the initial loading dose.
Preparation of solutions: for intramuscular administration, the drug is dissolved in 4-5 ml of water for injection, isotonic sodium chloride solution or 0.25-0.5% novocaine solution. For intravenous drip administration, the drug is dissolved in 100-250 ml of isotonic sodium chloride solution or 5% glucose solution, the injection is carried out for 20-30 minutes (injection rate of 60-80 drops per minute). For intravenous jet administration, a single dose of the drug is diluted in 10 ml of isotonic sodium chloride solution and injected slowly over 3-5 minutes. During dilution, the vials are shaken vigorously until completely dissolved.
Drug Interactions
Concomitant use with anticoagulants and diuretics is not recommended. With the simultaneous use of cefazolin and loop diuretics, a blockage of its tubular secretion occurs. Aminoglycosides increase the risk of kidney damage. Pharmaceutically incompatible with aminoglycosides (mutual inactivation). Drugs that block tubular secretion increase blood concentration, slow down excretion, and increase the risk of toxic reactions.
