Insights
Cefprozil (CFPZ) demonstrated high clinical and bacteriological effectiveness in pediatric infections, with a 96.4% overall efficacy rate. This oral cephalosporin showed excellent safety, with no observed side effects in children.
Area of Science:
- Pediatric Infectious Diseases
- Pharmacology
- Clinical Microbiology
Background:
- Cefprozil (CFPZ) is a novel oral cephalosporin evaluated for pediatric use.
- Assessing clinical efficacy, bacteriological outcomes, and safety is crucial for new antibiotics.
Observation:
- A study involved 116 pediatric patients aged 4 months to 11 years with various infections.
- Cefprozil was administered at 4.6-14.1 mg/kg daily for 3-10 days.
- Clinical and bacteriological data were collected from 112 patients.
Findings:
- Cefprozil achieved a 96.4% clinical effectiveness rate across infections like pharyngitis, tonsillitis, pneumonia, and UTI.
- Bacteriological eradication rates were 97.1% for Gram-positive and 56.8% for Gram-negative bacteria.
- No significant side effects or ingestion refusal were noted; minor laboratory abnormalities were rare.
Implications:
- Cefprozil is a safe and highly effective antibiotic for treating common pediatric infections.
- Its favorable safety profile and efficacy support its use in pediatric clinical practice.
- Further research may explore its role against resistant bacterial strains.
Abstract:
Clinical efficacy and safety of cefprozil (CFPZ, BMY-28100), a newly developed oral cephalosporin, were studied in our pediatric department. Clinical effectiveness, bacteriological effectiveness and side effects were studied in 116 pediatric patients with ages ranging 4 months to 11 years. CFPZ was given 4.6-14.1 mg/kg daily in 3 times for 3-10 days. Clinical efficacies were evaluated in 112 patients, and the therapeutic effectiveness were excellent in 1 and good in 6 for 7 patients with acute pharyngitis, excellent in 24 and good in 26 for acute purulent tonsillitis, excellent in 3, good in 8 and fair in 1 for acute bronchitis, excellent in 21, good in 7, fair in 1 and poor in 1 for acute pneumonia, excellent in 1 acute purulent parotitis, excellent in 2 and good in 7 for acute UTI, good in 1 impetigo, fair in 1 periproctal abscess and good in 1 acute enteritis. The effectiveness rate was 96.4%. Bacteriologically, 4 strains of Staphylococcus aureus (beta-lactamase producing strains), 1 strain of Staphylococcus epidermidis (beta-lactamase producing strain), 2 strains of Streptococcus pneumoniae, 2 strains of Streptococcus agalactiae, 4 strains of beta-Streptococcus, 1 strain of Klebsiella pneumoniae (beta-lactamase producing strain) and 1 strain of Salmonella C2 were all disappeared, and of 22 strains of Streptococcus pyogenes, 20 strains were disappeared, 1 was decreased and 1 was unknown, of 5 strains of Escherichia coli (3 beta-lactamase producing strains), 4 were disappeared and 1 was decreased, of 29 strains of Haemophilus influenzae (14 beta-lactamase producing strains), 14 were disappeared, 11 were decreased, 3 persisted and 1 was unknown and of 2 strains of Haemophilus parainfluenzae (1 beta-lactamase producing strain), 1 was disappeared and 1 persisted. The bacteriological eradication rates for Gram-positive bacteria and Gram-negative bacteria were 97.1% and 56.8%, respectively, and the drug was especially effective against Gram-positive bacteria. No side effects nor refusal of ingestion were observed. As abnormalities in laboratory test results, 3 cases of elevation of eosinophil counts and 1 of elevation of platelet counts were observed. In conclusion, CFPZ was considered to be a safe and highly effective antibiotic in pediatric infections.
