Concentrations of ticarcillin and clavulanic acid in human bone after prophylactic administration of 5.2 g of timentin.

The penetration of ticarcillin and clavulanate into their distribution space within human bone was determined after prophylactic administration of 5.2 g of timentin (5 g of ticarcillin plus 0.2 g of clavulanic acid) to 20 patients undergoing hip surgery. All samples were taken 45 to 85 min postadministration. The mean concentrations of ticarcillin in spongiosa and corticalis bone were 57.1 and 70.5 mg/kg, respectively; those of clavulanic acid were 17.8 and 32.5 mg/kg, respectively. No infections occurred in these patients.
