[Laboratory and clinical studies of cefdinir 5% and 10% fine granules in pediatric field].

We have carried out laboratory and clinical studies on cefdinir (CFDN) 5% and 10% fine granule preparations. The results are summarized as follows. CFDN 5% fine granule preparation was given via oral route to each of 2 children in the fasting state at a single dose of 3 mg/kg. After administration, the mean peak plasma level of CFDN was 0.76 micrograms/ml at 4 hours and the mean half-life was 1.77 hours. The mean urinary excretion rate of CFDN was 31.5% in the first 12 hours after oral administration. CFDN 10% fine granule preparation and CFDN 100 mg capsule were given via oral route 3 children and to another child in the fasting state at single doses of 3 mg/kg and 2.63 mg/kg, respectively. After administration of 10% granules the mean peak plasma level of CFDN was 0.73 micrograms/ml at 2 hours and the mean half-life was 1.62 hours. The peak serum level obtained after administration of CFDN 100 mg capsule was 0.91 micrograms/ml at 2 hours and the half-life was 1.08 hours. The mean urinary excretion rate obtained with CFDN 10% fine granules was 26.2% in the first 8 hours after oral administration and the urinary excretion rate obtained with CFDN 100 mg capsule was 19.7% in the first 12 hours after oral administration. Treatment with CFDN 5% fine granules was made for a total of 48 cases of pediatric bacterial infections including 21 cases of tonsillitis, 12 cases of scarlet fever, 3 cases of pharyngitis, 5 cases of impetigo, 1 case of subcutaneous abscess, 1 case of furuncle, 5 cases of UTI. Results obtained were excellent in 30 cases, good in 18 cases. Treatment with CFDN 10% fine granules was made for a total of 16 cases of pediatric bacterial infections including 6 cases of tonsillitis, 3 cases of pneumonia, 4 cases of scarlet fever, 2 cases of impetigo, 1 case of UTI. Results obtained were excellent in 8 cases, good in 7 cases, poor in 1 case. No significant side effects due to the drugs were observed except 2 cases (1 case with 5% preparation and another with 10%) with eosinophilia, 3 cases (all with 5%) with diarrhea and 1 case each of elevated GOT & GPT (with 5%) and elevated GOT, GPT & Al-P (with 10%).
