1Department of Pediatrics, School of Medicine, Teikyo University, Tokyo, Japan.
Insights
Cefpodoxime proxetil suspension demonstrated high clinical efficacy (94.7%) and bacteriological eradication rates in pediatric infections. This oral cephalosporin showed a dose response and enhanced absorption when taken before meals, with a favorable safety profile.
Area of Science:
- Pharmacology
- Pediatric Infectious Diseases
- Antimicrobial Agents
Background:
- Cefpodoxime proxetil is an oral cephalosporin antibiotic used for various infections.
- Evaluating its suspension formulation in pediatric patients is crucial for effective treatment.
- Understanding its pharmacokinetic and efficacy profile in children is essential.
Purpose of the Study:
- To assess the pharmacokinetics, clinical efficacy, and safety of cefpodoxime proxetil suspension in pediatric patients.
- To determine the dose-response relationship and absorption characteristics.
- To evaluate bacteriological eradication rates and identify potential side effects.
Main Methods:
- A study involving pediatric patients with various infections.
- Administration of single doses of 3 and 6 mg/kg (cefpodoxime equivalent) of the suspension.
- Monitoring of serum concentrations, clinical response, bacteriological eradication, and adverse events.
Main Results:
- A clear dose-response relationship was observed in serum concentrations.
- Absorption was enhanced when the suspension was taken before meals.
- High overall clinical efficacy (94.7%) and bacteriological eradication rates (90.0%) were achieved.
- A low incidence of side effects (2.29%) and transient laboratory abnormalities were noted.
Conclusions:
- Cefpodoxime proxetil suspension is effective and safe for treating infections in pediatric patients.
- Administration before meals optimizes absorption and potentially enhances therapeutic outcomes.
- The study supports the use of this antibiotic in pediatric populations.
Abstract:
The pharmacokinetics, bacteriological and clinical efficacy, and safety of the suspension formulation of cefpodoxime proxetil, an oral cephalosporin antibacterial, were evaluated in paediatric patients with various infections. With single doses of 3 and 6 mg/kg (cefpodoxime equivalent) a dose response was evident in the serum concentration values. Absorption, as evidenced by serum concentrations and areas under the concentration-time curve, was enhanced when the suspension was administered before a meal. The overall clinical efficacy (defined as an excellent or good response) in evaluable patients (those from whom a pathogen was isolated) was 94.7% (451 of 476). Bacteriological eradication rates were as follows: Gram-positive bacteria 91.3%; Gram-negative bacteria 88.6%, and 90.0% overall. Side effects occurred in 17 (2.29%) patients, and transient and reversible abnormal laboratory values were found in a few patients.
