Penetration of Aminoglycosides into Human Peritoneal Tissue

Abstract

Each of 30 patients underwent elective laparotomy following administration of a single intravenous dose of amikacin, netilmicin or tobramycin. Therapeutic concentrations of amikacin were achieved in peritoneal tissue in 10/10 patients. Only 13/20 samples from patients receiving the other two antibiotics showed antibacterial activity. Our data suggest that the penetrability of tobramycin (53%) and amikacin (39%) into the uninflamed peritoneal tissue is superior to that of netilmicin (16%).
