Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Provides essential fatty acids (linoleic and linolenic) and calories for patients requiring parenteral nutrition; fatty acids are incorporated into cell membranes and serve as precursors for prostaglandins.
Lipid emulsion providing essential fatty acids (linoleic and linolenic acids) and calories for parenteral nutrition. The triglycerides are hydrolyzed by lipoprotein lipase to free fatty acids and glycerol, which are then utilized for energy or stored.
Intravenous infusion; maximum daily dose of 2.5 g/kg (25 mL/kg) provided as part of parenteral nutrition, typically administered over 12-24 hours.
Intravenous fat emulsion; 20% formulation: Initial rate 1 mL/min for 15-30 minutes, then increase to 2 mL/min if tolerated. Max infusion rate: 100 mL/hour. Total daily dose: 1-2 g/kg (5-10 mL/kg) to provide up to 60% of nonprotein calories.

18–24 hours for clearance of infused triglycerides; terminal elimination half-life of soybean oil emulsion particles is approximately 30 minutes for particles <1 µm, but longer for larger particles (up to several hours); clinical context: prolonged half-life in renal/hepatic impairment.
Terminal elimination half-life of triglycerides is approximately 30 minutes for the fast phase and 12-24 hours for the slow phase, reflecting clearance from plasma and tissue distribution.
Renal: negligible; biliary/fecal: negligible; metabolized in tissues (e.g., muscle, adipose) via beta-oxidation and re-esterification; CO2 production via tricarboxylic acid cycle accounts for majority of elimination.
Intravenous lipid emulsions are metabolized by lipoprotein lipase and eliminated as free fatty acids; less than 1% excreted unchanged in urine, negligible biliary/fecal excretion.
