Clinical pharmacology of cefotaxime in pediatric patients
Insights
Cefotaxime effectively treated infections in 97% of pediatric patients with minimal toxicity. This cephalosporin demonstrated favorable pharmacokinetics in infants and children, similar to adults, supporting its use in pediatric infectious diseases.
Area of Science:
- Pharmacology
- Pediatric Infectious Diseases
- Antimicrobial Therapy
Background:
- Cefotaxime is a third-generation cephalosporin antibiotic.
- Its broad spectrum of activity suggests potential utility in pediatric populations.
Purpose of the Study:
- To evaluate the efficacy and safety of cefotaxime in infants and children.
- To characterize the pharmacokinetic profile of cefotaxime in this age group.
Main Methods:
- Cefotaxime was administered to 33 pediatric patients.
- Clinical outcomes, pathogen eradication, and adverse events were monitored.
- Pharmacokinetic parameters including elimination half-life, volume of distribution, and clearance were determined.
Main Results:
- 97% of patients experienced clinical cure or improvement.
- 94% of isolated pathogens were eradicated.
- Toxicity was minimal.
- Pharmacokinetic parameters in pediatric patients were comparable to adult data (elimination half-life ~1.5 h, Vd 1 L/kg, CL 10 mL/min/kg).
Conclusions:
- Cefotaxime is an effective and well-tolerated antibiotic for treating infections in pediatric patients.
- The pharmacokinetic disposition of cefotaxime in infants and children is similar to adults, supporting its therapeutic use.
Abstract:
Cefotaxime is a new cephalosporin with a spectrum of activity which may make it appropriate for use in pediatric patients. In 33 infants and children, administration of cefotaxime resulted in cure or improvement in 97% of patients, with eradication of 94% of isolated pathogens. Toxicity was minimal. The disposition of cefotaxime in this age group was similar to that reported for adults, with an elimination half-life of approximately 1.5 h, a volume of distribution of 1 liter/kg, a total serum clearance of 10 ml/min per kg, and a renal clearance of 6 ml/min per kg.
