Pharmacological studies with cefamandole in human volunteers.

Serum and urine concentrations were measured after administration of 0.5-and 1-g doses of cefamandole intramuscularly and intravenously to healthy volunteers. Intramuscular doses of 0.5 and 1 g yielded serum concentrations at 1 h of 14.7 and 35.6 mug/ml, respectively. Significant antibacterial concentrations persisted through h 8. Intravenous doses of 0.5 and 1 g resulted in respective peak serum levels of 21 mug/ml at 45 min and 103 mug/ml at 15 min; these serum levels rapidly declined. Very high urine concentrations were achieved during the first 8 h after injection.
