[Basic studies of cefotiam (author's transl)].
The basic studies of cefotiam (CTM) were performed, and the following results were obtained. 1. One shot intravenous injection of 40 mg/kg of CTM (1) Serum levels: The mean levels of CTM in 3 children were 133.9 micrograms/ml after 15 minutes, 71.5 micrograms/ml after 30 minutes 32.6 micrograms/ml after 1 hour, 9.2 micrograms/ml after 2 hours, 2.5 micrograms/ml after 4 hours, 0.9 microgram/ml after 6 hours. The serum half life of CTM was approximately 1.2 hours on beta-phase. (2) Urinary excretion: The mean urinary excretions were 39.4% over 3 hours, 44.7% over 4 hours, 45.7% over 6 hours. 2. 1 hour-drip infusion of 40 mg/kg of CTM (1) Serum levels: The mean serum levels of CTM in 4 children were 140.1 micrograms/ml at immediately after drip infusion was completed, 10.6 micrograms/ml after 1 hour, 3.8 micrograms/ml after 2 hours, 1.4 micrograms/ml after 3 hours, 0.5 microgram/ml after 5 hours. The serum half life of CTM was approximately 1.0 hour on beta-phase. (2) Urinary excretions: The mean urinary excretions were 42.9% over 2 hours, 48.0% over 4 hours, 48.7% over 6 hours. 3. Bioactive metabolite in serum and urine: No bioactive metabolites were observed in either serum or urine after administration of 40 mg/kg of CTM.
