Pharmacokinetics of moxalactam in patients with renal failure and during hemodialysis.

The pharmacokinetics of moxalactam were determined in eight patients with end stage renal disease who were undergoing chronic hemodialysis. The mean half-life of moxalactam in the interdialysis period was 19 h, with a range of 9 to 30 h. The mean half-life of moxalactam during dialysis was 4 +/- 0.58 h. Serum levels of 30 +/- 10 micrograms/ml were present 24 h after a 1-g dose in the interdialysis period. A dose of 1 g at the end of each dialysis period in patients undergoing thrice-weekly hemodialysis would provide levels far in excess of the minimal inhibitory levels against Enterobacteriaceae.
