[Pharmacokinetics of ceftazidime injected peritoneally in continuous ambulatory peritoneal dialysis].

Peritonitis is the most frequent complication in patients under continuous ambulatory peritoneal dialysis. Intraperitoneal administration of ceftazidime in a dose of 125 mg per liter dialysate achieved serum concentrations higher than the minimal inhibitory concentrations of most organisms in spite of low peritoneal clearance. Serum concentration was stable up to the 120th hour. Dialysate osmolarity had no influence on serum concentration, peritoneal absorption or clearance of ceftazidime. Peritoneal inflammation did not cause changes in ceftazidime pharmacokinetics. Ceftazidime used alone as the first choice treatment was successful in 85%, of cases.
