Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Peritoneal dialysis solution with dextrose as osmotic agent; removes solutes and water across peritoneal membrane via diffusion and ultrafiltration.
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.
Intraperitoneal administration: 2 L per exchange, typically 4 exchanges daily (continuous ambulatory peritoneal dialysis). Dextrose 4.25% solution used for ultrafiltration. Dose adjusted based on body size and fluid status.
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.

Not applicable as a drug; dextrose is rapidly metabolized; plasma half-life of glucose ~1.5-2 hours; continuous reabsorption in dialysis prevents accumulation.
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.
Peritoneal dialysis; effectively removed via peritoneal membrane during dialysis exchanges; systemic absorption of dextrose minimal; elimination primarily through dialysate outflow; renal excretion negligible in anuria.
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%).
