DELFLEX-LM W/ DEXTROSE 2.5% IN PLASTIC CONTAINER vs EXTRANEAL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Delflex-LM with Dextrose 2.5% is a peritoneal dialysis solution. Dextrose provides osmotic gradient for ultrafiltration; lactate (LM) is a bicarbonate precursor that buffers metabolic acidosis. The solution replaces fluid and electrolytes while removing waste products via diffusion and convection across the peritoneal membrane.
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 liters of 2.5% dextrose solution per exchange, typically 4 exchanges daily (8 liters total). Adjust volume and frequency based on patient's dry weight, residual renal function, and peritoneal membrane transport characteristics.
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.

Dextrose: ~1-2 hours for plasma glucose levels; lactate: ~30-60 minutes for conversion to bicarbonate.
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 fluid components: dextrose is metabolized to CO2 and water; lactate is converted to bicarbonate in liver; electrolytes are variably reabsorbed. ~70% of administered dextrose is absorbed; elimination primarily via metabolic pathways.
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%).
