Cefprozil (CFPZ, BMY-28100) is a new oral cephem antibiotic without an ester linkage. Pharmacokinetic and clinical studies using CFPZ 10% fine granules were performed in pediatric patients. 1. Pharmacokinetic investigation Peak serum concentrations of CFPZ after dose of 7.5 mg/kg and 10 mg/kg were, respectively, 3.65 +/- 0.24 micrograms/ml and 6.38 +/- 3.23 micrograms/ml at 1-2 hours. The average half-life with 7.5 mg/kg administration was 0.90 +/- 0.16 hours and that with 10 mg/kg was 1.29 +/- 0.50 hours. The urinary excretion of CFPZ was about 45% (35.3-50.0%) in 6 hours. 2. Clinical investigation Enrolled in the study were 22 patients including 4 with pharyngitis, 3 with tonsillitis, 3 with bronchitis, 5 with pneumonia, 4 with urinary tract infection, and 1 each with pertussis, purulent lymphadenitis and otitis media. Responses were excellent in 14 patients, good in 5 patients and fair in 1 patient. In the assessment of the bacteriological efficacy, 8 out of 17 strains of organism identified previous to the treatment were eradicated, 5 strains were found replaced by other bacteria and 4 strains persisted, hence the eradication rate was 76.5%. 3. No adverse reactions attributable to the drug were observed. From the above results, it has been concluded that CFPZ is a highly effective and safe agent for moderate respiratory and urinary tract infections in children.

Cefprozil (CFPZ, BMY-28100) granules was administered to a group of pediatric patients. The new oral cephalosporin, CFPZ, was evaluated clinically in 42 pediatric patients, and a pharmacokinetic study was performed in 6 patients. Serum and urinary concentrations of CFPZ were determined in 6 patients who were given single dose of 7.5 or 15.0 mg/kg. Serum concentrations were determined at 1, 2, 3, 4 and 6 hours after dosing. Urinary concentrations were measured for periods of 0-6 hours after dosing. With oral administrations of 7.5 mg/kg and 15.0 mg/kg, peak serum concentrations were 2.13 micrograms/ml and 6.22 micrograms/ml, respectively, at 2 hours, and biological half-lives were 1.06 hours and 1.36 hours, respectively. Urinary recovery rates were 44.8% and 56.1%. The clinical evaluation was conducted in 41 patients including 16 patients with acute tonsillitis, 8 patients with lacunar tonsillitis, 4 patients with scarlet fever, 3 patients with acute bronchitis, 1 patient each with pertussis, furuncle, impetigo and lymphadenitis, and 6 patients with urinary tract infections. The ages of the patients were 10 month to 11 years 1 month, and they were treated with CFPZ at doses ranging 9.0-45.0 mg/kg daily for 3-14 days, the overall clinical efficacy rate was 92.7%. An eradication rate of 79.2% was achieved for 28 strains of 8 species identified in the patients. No side effects were observed. Abnormal laboratory test results obtained were eosinophilia in 2 patients.
