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-LC/LM with 3.5% dextrose is a peritoneal dialysis solution that provides osmotic ultrafiltration via dextrose, removing waste products and excess fluid from the blood across the peritoneal membrane. The low calcium (LC) and low magnesium (LM) formulations adjust electrolyte concentrations to manage 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.
Intraperitoneal administration: 2 to 2.5 liters per exchange, 4 to 5 exchanges per day, as prescribed by physician based on peritoneal equilibration test.

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; dextrose is continuously infused and removed; the half-life of intraperitoneal dextrose is approximately 1-2 hours due to rapid absorption and metabolism, with clinically relevant hyperglycemia managed by insulin.
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 (via peritoneal dialysis effluent); approximately 60-70% of administered dextrose is absorbed and metabolized, with the remainder removed in dialysate; no significant biliary/fecal elimination.
