Abstract
This study determined the pharmacokinetic disposition of cefonicid. A single dose of 7.5 mg/kg of body weight was administered to five healthy volunteers as a 5-min intravenous infusion. Multiple plasma and urine samples were collected for 48 h. Peak plasma concentrations ranged from 95 to 156 micrograms/ml and fell slowly (mean plasma half-life, 4.4 +/- 0.8 h), so that levels after 12 h were in the range of 6 to 12 micrograms/ml. Urinary concentrations were high but variable and ranged from 100 to 1,000 micrograms/ml for the first 12 h after the dose and averaged 84 micrograms/ml between 12 and 24 h. Plasma and renal clearances were 0.32 +/- 0.06 and 0.29 +/- 0.05 ml/min per kg, respectively. An average of 88 +/- 6% of the dose was excreted unchanged in the urine over 48 h. The mean steady-state volume of distribution was found to be 0.11 +/- 0.01 liters/kg.
