title: Pharmacokinetics of cefodizime during continuous ambulatory peritoneal dialysis.
abstract: In a single-dose open cross-over trial we studied the pharmacokinetics of cefodizime 1 g in four uraemic patients treated by continuous ambulatory peritoneal dialysis (CAPD). Cefodizime was administered, successively with a wash out, (a) iv over 3 min and (b) by intraperitoneal (ip) administration together with the dialysate fluid (2 litres). Concentrations of cefodizime were measured by HPLC in blood and dialysate samples collected during an 8-h dwell period and in additional dialysate samples collected up to 48 h after drug administration. The mean (relative) total clearances following the iv and ip administration were 23 and 31 ml/min, respectively, and the terminal half-lives 5.5 and 6.7 h, respectively. Following iv administration, the peritoneal clearance was approximately 0.5 ml/min. After ip administration high concentrations of cefodizime were measured in the dialysate throughout the dwell period and systemic availability was good (80%) but variable.
