Piperacillin distribution into bile, gallbladder wall, abdominal skeletal muscle, and adipose tissue in surgical patients.

The concentrations of piperacillin in serum, bile, gallbladder wall, abdominal skeletal muscle, and adipose tissue were measured simultaneously at various times after the intravenous administration of a single 5-g dose to each of 14 patients undergoing biliary tract surgery. Piperacillin concentrated in the bile with peak levels exceeding 4,000 micrograms/ml. In a single patient with cystic duct obstruction, trace gallbladder bile piperacillin levels were measured. Gallbladder wall concentrations of piperacillin tended to be higher than corresponding serum concentrations, with a correlation observed between tissue values and the degree of acute gallbladder inflammation and gallbladder bile piperacillin concentrations. Mean peak muscle and adipose tissue piperacillin concentrations of 31 and 27 micrograms/g, respectively, were reached at between 2 and 3 h after the start of infusion. These concentrations exceeded the minimum inhibitory concentration for a majority of susceptible organisms. A single 5-g dose of piperacillin achieved therapeutic levels in gallbladder wall, intraabdominal skeletal muscle, and adipose tissue and concentrated in the bile of patients with patent biliary tracts.[1]
