A study on tissue concentrations of cephradine achieved in patients with peripheral vascular disease.

The levels of cephradine were measured in serum, voluntary muscle and subcutaneous fat samples collected from 30 patients during surgical operations for peripheral vascular disease. Cephradine 2 g was administered in two equal doses by intramuscular and intravenous routes before each operation. The mean levels found in the serum and muscle were well above the minimum inhibitory concentrations required for most important Gram-positive and Gram-negative pathogens, in contrast to the relatively low mean level found in subcutaneous fat.
