Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Extraneal (icodextrin) is a glucose polymer that acts as an osmotic agent for peritoneal dialysis. It is absorbed from the peritoneal cavity into the bloodstream and metabolized to maltose and other oligosaccharides. Its primary mechanism is to create an osmotic gradient across the peritoneal membrane, facilitating ultrafiltration and removal of waste products.
Provides osmotic gradient for peritoneal dialysis; glucose and icodextrin facilitate ultrafiltration and removal of waste products across the peritoneal membrane.
7.5% solution: 2 L intraperitoneally, dwell time 4–8 hours, up to 4 exchanges per day. For automated peritoneal dialysis: 2 L per cycle, typically 3–5 cycles overnight.
2 L intraperitoneally via an indwelling peritoneal catheter, dwell time 4-6 hours, 4 exchanges per day

The terminal elimination half-life of icodextrin in plasma is approximately 19 hours (range 12-22 hours) following intraperitoneal administration for a dwell of 8-12 hours. This long half-life reflects slow metabolism and clearance, particularly relevant in patients with impaired renal function, leading to accumulation of maltose and other oligosaccharides.
Not applicable as a traditional half-life; removal is dependent on peritoneal dialysis dwell time and membrane transport characteristics. Effective clearance half-life during dialysis is approximately 2-4 hours depending on exchange schedule.
Icodextrin is metabolized to maltose, maltotriose, and other oligosaccharides. After intraperitoneal administration, approximately 40% of the administered dose is absorbed systemically; the absorbed icodextrin and its metabolites are primarily eliminated by renal excretion (via glomerular filtration). In patients with residual renal function, approximately 30-40% of the absorbed dose is excreted in urine over 14 days. Biliary/fecal excretion is negligible (<1%).
Primarily removed via peritoneal dialysis; minimal renal excretion (less than 5% unchanged). Dextrose is metabolized to CO2 and water. Biliary/fecal excretion negligible.
