Summary We have compared in two separate studies the kinetics of ceftriaxone and cefotaxime in 8 cirrhotic patients with ascites and 8 control subjects after a single 20 min intravenous infusion of 1 g of each drug. The apparent volumes of distribution (Vz) were found to be significantly higher in cirrhotics than in control subjects (0.87, versus 0.49, l·kg−1, for cefotaxime and 0.23 versus 0.13 for ceftriaxone). The elimination kinetics of ceftriaxone were similar in the two groups. In contrast, the total and non-renal clearances of cefotaxime were reduced in cirrhotic patients. The two drugs rapidly entered the ascitic fluid. Peritoneal concentrations of ceftriaxone were higher than 7 µg·ml−1 from the second hour after the infusion and were 8.9 µg·ml−1 at 24 h. Peritoneal concentrations of cefotaxime were higher than 4 µg·ml−1 from 0.5 to 8 h after the infusion.
