INTRALIPID 20% vs NUTRILIPID 10%
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Intralipid 20% is a fat emulsion providing essential fatty acids and triglycerides. It serves as a source of calories and essential fatty acids. In parenteral nutrition, it prevents and treats essential fatty acid deficiency. In lipid rescue therapy for local anesthetic toxicity, it acts as a 'lipid sink' to sequester lipophilic drugs, and may also enhance mitochondrial fatty acid oxidation and improve cardiac contractility.
Nutrilipid 10% is a fat emulsion that provides essential fatty acids (linoleic and linolenic acids) and a source of calories. It serves as a component of parenteral nutrition, supplying triglycerides that are metabolized to free fatty acids and glycerol for energy production and cellular functions.
Intravenous infusion at a rate of 0.1 g fat/kg/hour, increasing to 0.5 g fat/kg/hour if tolerated. Maximum daily dose: 2.5 g fat/kg (50 mL/kg/day of 20% emulsion).
Intravenous infusion, 1-2 g/kg/day (0.5-1 g/kg/day for 10% emulsion), not to exceed 2.5 g/kg/day. Initial rate 0.5-1 mL/min for first 15-30 minutes, then increase to maximum of 125 mL/hour.

Terminal elimination half-life of lipid particles: approximately 30 minutes for chylomicron-like particles; triglycerides half-life ~15-30 minutes. Clinical context: rapid clearance by lipoprotein lipase.
Terminal elimination half-life: approximately 0.5-1 hour for the triglyceride component in healthy adults; clinically, clearance depends on infusion rate and metabolic capacity, with prolonged half-life in hypertriglyceridemia.
Renal: negligible. Biliary/fecal: >90% as component of lipid metabolism, excretion via bile and fecal elimination of lipid particles.
Renal: negligible; biliary/fecal: not applicable as lipid emulsion is metabolized; elimination primarily via lipoprotein lipase-mediated clearance from plasma.
