Insights
Cefprozil (CFPZ) demonstrated favorable pharmacokinetics and high efficacy in treating pediatric bacterial infections. This cephalosporin antibiotic showed good tolerability with minimal side effects in clinical studies.
Area of Science:
- Pharmacology
- Pediatric Infectious Diseases
- Clinical Microbiology
Background:
- Cefprozil (CFPZ) is a novel oral cephalosporin antibiotic.
- Pediatric bacterial infections require effective and safe treatment options.
Purpose of the Study:
- To evaluate the pharmacokinetics of cefprozil in pediatric patients.
- To assess the clinical efficacy and safety of cefprozil in treating various pediatric bacterial infections.
Main Methods:
- Laboratory and clinical studies were conducted.
- Cefprozil was administered orally at a single dose of 7.5 mg/kg to two pediatric patients.
- Clinical efficacy was assessed in 37 pediatric cases with bacterial infections.
Main Results:
- Peak serum levels of cefprozil ranged from 6.45 to 6.71 µg/ml within 1-2 hours.
- Urinary excretion rates were approximately 59%, with half-lives between 0.92-1.28 hours.
- Excellent or good clinical outcomes were observed in all 37 pediatric patients, with no significant adverse effects reported.
Conclusions:
- Cefprozil exhibits favorable pharmacokinetic properties in children.
- Cefprozil is an effective and well-tolerated antibiotic for treating pediatric bacterial infections.
Abstract:
Laboratory and clinical studies were done on cefprozil (CFPZ, BMY-28100). The results are summarized as follows. CFPZ was administered through the oral route to 2 children at a single dose of 7.5 mg/kg. After administration, peak serum levels of CFPZ obtained in the 2 cases were 6.71 micrograms/ml at 1 hour and 6.45 micrograms/ml at 2 hours, respectively and half-lives were 1.28 hours and 0.92 hour, respectively. The urinary excretion rates of CFPZ were 58.9% and 59.4%, respectively. Treatment with CFPZ was made in 37 cases of pediatric bacterial infections: 1 case of pharyngitis, 16 cases of tonsillitis, 16 cases of scarlet fever, 3 cases of impetigo, 1 case of UTI. Results obtained were excellent in 24 cases, good in 13 cases. No significant side effects due to the drug were observed, except 1 case of loose stool, 3 cases of eosinophilia, and 1 case each of elevated GOT and GPT.
