[Pharmacokinetic and clinical studies on cefozopran in pediatrics].

Abstract	Cefozopran (CZOP, SCE-2787), a new parenteral cephalosporin antibiotic, was studied for its pharmacokinetics, bacteriological and clinical effects in the field of pediatrics. The serum and cerebrospinal fluid concentrations 1 hour after a bolus intravenous injection of 50 mg/kg were, respectively, 92.1, 10.5 micrograms/ml, and penetration rate to cerebrospinal fluid of CZOP in patients with purulent meningitis was 11.4%. 25 patients, including those with purulent meningitis, pneumonia, urinary tract infections, staphylococcal scalded skin syndrome (SSSS) etc., were treated with CZOP at dose levels of 16.0 to 50.0 mg/kg 3-4 times daily, via intravenous injection and intravenous drip infusion. CZOP gave "excellent" or "good" responses in all the 25 patients. In bacteriological examinations, 25 strains were identified and were eradicated except 1 strain of Staphylococcus aureus and 2 strains of Salmonella sp. As a side effect, diarrhea was observed in 1 patient among the 27 patients treated with the drug. As for abnormal laboratory findings, eosinophilia was observed in 1 patient, increases of thrombocytes in 3 and GPT in 2. Influences on blood coagulation parameters were studied. No changes in PIVKA II, HPT or APTT were observed during the treatment. Based on the above results, it has been concluded that CZOP is a safe and effective drug to use in the treatment of pediatric infections. The normal recommended dosage and administration should be 20 to 50 mg/kg of CZOP at a time, using intravenous injection or intravenous drip infusion 3 to 4 times a day.
