Insights
Cefprozil (CFPZ) is a new oral cephalosporin antibiotic that demonstrated high efficacy and safety in treating bacterial infections in children. The study found an overall efficacy rate of 90.5% with minimal adverse effects.
Area of Science:
- Pediatric infectious diseases
- Pharmacology and therapeutics
- Antimicrobial agents
Background:
- Bacterial infections pose a significant health concern in pediatric populations.
- The need for effective and safe oral antibiotics in children is critical.
- Cephalosporins are a widely used class of antibiotics for bacterial infections.
Purpose of the Study:
- To evaluate the efficacy and safety of Cefprozil (CFPZ), a new oral cephalosporin, in pediatric patients.
- To determine the clinical outcomes and microbiological eradication rates of CFPZ treatment.
- To identify any adverse events associated with CFPZ administration in children.
Main Methods:
- A clinical trial involving 42 children diagnosed with various bacterial infections.
- Cefprozil (CFPZ) was administered at daily dosages ranging from 15.3 to 60.0 mg/kg in 3 or 4 divided doses.
- Clinical efficacy was assessed, and causative organisms were monitored for eradication. Safety was evaluated through laboratory tests and observation of adverse events.
Main Results:
- An overall efficacy rate of 90.5% was achieved, with 24 excellent, 14 good, and 4 fair responses.
- Causative organisms were eradicated in 19 out of 28 cases examined.
- Adverse events were generally mild, including diarrhea in 2 cases and eosinophilia in 2 cases. Slight elevations in S-GOT and S-GPT were noted in one case.
Conclusions:
- Cefprozil (CFPZ) is a safe and effective new oral antibiotic for treating susceptible bacterial infections in children.
- The drug demonstrated a high clinical efficacy and a favorable safety profile in the pediatric population.
- CFPZ represents a valuable therapeutic option for pediatric infectious diseases.
Abstract:
Cefprozil (CFPZ, BMY-28100), a new oral cephalosporin, was evaluated for its efficacy and safety in 42 children with bacterial infections (Table 1), and the following results were obtained. 1. CFPZ was administered in 3 or 4 divided doses at daily dosages ranging from 15.3 to 60.0 mg/kg to 42 patients (19 cases of acute tonsillitis and/or laryngitis, pharyngitis, 13 cases of pneumonia, 2 cases each of suppurative cervical lymphadenitis and UTI, and 1 case each of scarlet fever, acute otitis media, suppurative parotitis, impetigo contagiosa, furuncle and acute enteritis) and the following clinical results were obtained: excellent; 24 cases, good; 14 cases, fair; 4 cases. The overall efficacy rate was 90.5% (Table 3). 2. MICs of CFPZ against 50 strains of isolated organisms are shown in Table 4. In 19 cases out of 28 cases examined, causative organisms were successfully eradicated and strain of Staphylococcus aureus was decreased in 1 case. 3. Diarrhea was observed in 2 cases (cases 8, 11). In case 8, the symptom disappeared spontaneously. Case 11 improved immediately after the administration of the drug was stopped. Among 39 children who went through laboratory tests, eosinophilia which seemed to be related to the administration of this drug was observed in 2 cases (cases 29, 38). Slight elevations of S-GOT and S-GPT were found in 1 case (case 22) (Table 7). 4. These data suggest that CFPZ is a safe and useful new antibiotic in the treatment of children with susceptible bacterial infections.
