[Pharmacokinetic and clinical study of cefpirome in children]

Pharmacokinetic and clinical studies of cefpirome (CPR) in children were carried out, and the following results were obtained. 1. Peak serum levels were obtained at the end of drip infusion of 20.0, 17.5 and 6.8 mg/kg for 30 minutes and the half-lives were 1.93, 1.91 and 0.48 hours, respectively. 2. Urinary excretion rates in 6 hours were 40.0-96.2%. 3. Thirty-two patients including 17 with respiratory infections, 7 with urinary tract infections and 8 with skin and soft tissue infections were treated with CPR at 52.2-92 mg/kg per day by intravenous administration. Clinical effects were excellent in 12 cases, good in 13 cases, fair in 3 cases and unknown in 4 cases, and the overall efficacy rate was 89.3% (25 cases/28 cases). 4. Bacterial eradication rate was 93.8% (15 strains/16 strains). 5. Rash and diarrhea were found in 1 case each, and abnormal laboratory test values were found in 7 cases.
