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.
Inpersol-ZM w/ Dextrose 1.5% is a peritoneal dialysis solution that acts by creating a concentration gradient across the peritoneal membrane. The dextrose component provides an osmotic driving force that promotes ultrafiltration and removal of waste products (e.g., urea, creatinine) and excess electrolytes from the blood into the dialysate fluid, which is then drained from the peritoneal cavity. The electrolyte composition (sodium, chloride, calcium, magnesium, lactate) helps correct acid-base and electrolyte imbalances.
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.
250 mL to 2 L intraperitoneally, instilled over 10-20 minutes, dwell for 4-6 hours, then drain. Typically 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 systemically; dextrose half-life is minutes due to rapid cellular uptake. In peritoneal dialysis, the half-life of glucose in the peritoneal cavity is approximately 30-60 minutes due to absorption into bloodstream.
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%).
Renal: 100% (dialysis fluid containing dextrose is removed directly; glucose is metabolized and not excreted unchanged). Dextrose undergoes cellular metabolism to CO2 and water.
