The kinetics of cefotiam and cefsulodin were studied in plasma and dialysate after intravenous and intraperitoneal administration of 1 g to patients undergoing continuous ambulatory peritoneal dialysis. Instillation of autologous hemoglobin as a marker permitted calculation of the cavity volume and, hence, the rate of transfer to and from the peritoneal cavity with time. The patients were divided into 4 groups. Groups 1 and 2 were intravenously given cefotiam (5 patients) and cefsulodin (4 patients), respectively. Groups 3 and 4 (5 patients each) were given cefsulodin intraperitoneally. Group 3 did not have peritonitis, while the patients in Group 4 were studied during peritonitis. Blood and dialysate samples were obtained at selected times during the 5-hour dwell and, for plasma, until 24 hours after drug administration. Pharmacokinetic analysis of the data showed that only 6.0 and 8.7% of the intravenous doses of cefotiam and cefsulodin, respectively, were recovered in the dialysate at the end of the dwell. The net amounts of cefsulodin lost from the dialysate after intraperitoneal administration were 81 and 84%, in Groups 3 and 4 respectively. The peritoneal transfer clearances (using a unidirectional clearance model), calculated after intravenous (17 +/- 10 ml/min, Group 2) and intraperitoneal (17 +/- 5 ml/min, Group 3) administrations were the same. Mass balance of cefsulodin in the body and in the dialysate after intraperitoneal administration indicated that a significant amount (40%, Group 3) of the dose is unaccounted for. One explanation for this imbalance is retention of the drug in the peritoneal lining. This hypothesis is supported by the retention being lower in the peritonitis patients (less than 20%, Group 4), for whom the linings are expected to be partially eroded.

D010529	Peritoneal Cavity	The space enclosed by the peritoneum. It is divided into two portions, the greater sac and the lesser sac or omental bursa, which lies behind the STOMACH. The two sacs are connected by the foramen of Winslow, or epiploic foramen.	Greater Sac,Lesser Sac,Omental Bursa,Bursa, Omental,Cavity, Peritoneal,Sac, Greater,Sac, Lesser
D010531	Peritoneal Dialysis, Continuous Ambulatory	Portable peritoneal dialysis using the continuous (24 hours a day, 7 days a week) presence of peritoneal dialysis solution in the peritoneal cavity except for periods of drainage and instillation of fresh solution.	CAPD,Continuous Ambulatory Peritoneal Dialysis
D010538	Peritonitis	INFLAMMATION of the PERITONEUM lining the ABDOMINAL CAVITY as the result of infectious, autoimmune, or chemical processes. Primary peritonitis is due to infection of the PERITONEAL CAVITY via hematogenous or lymphatic spread and without intra-abdominal source. Secondary peritonitis arises from the ABDOMINAL CAVITY itself through RUPTURE or ABSCESS of intra-abdominal organs.
