Serum cefuroxime concentrations were measured over a 12 h period in ten
healthy adults following three iv dosing regimens: 750 mg cefuroxime, 1.5 g
cefuroxime, and 750 mg cefuroxime with 1 g of probenecid given orally 3 h
before the cefuroxime infusion. Probenecid prolonged the serum cefuroxime
half-life by 63% (P < 0.05) with a significant increase in the mean time
for which serum cefuroxime concentrations exceeded the MIC90 for common
respiratory pathogens (2 mg/L) compared with either 750 mg cefuroxime (2.2
h, P < 0.05) or 1.5 g of cefuroxime (0.9 h, P < 0.05) without
probenecid. The cost of the 750 mg cefuroxime dose plus probenecid is
approximately half that of a 1.5 g cefuroxime dose.
