AMINOSYN 8.5% vs TRAVASOL 5.5% SULFITE FREE W/ ELECTROLYTES IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn 8.5% is a crystalline amino acid solution that provides a source of nitrogen and essential/non-essential amino acids for protein synthesis, tissue repair, and maintenance of nitrogen balance. It serves as a substrate for metabolic pathways, including gluconeogenesis and ketogenesis, and supports immune function and enzyme production.
Travasol 5.5% with electrolytes provides a source of amino acids and electrolytes for parenteral nutrition, supporting protein synthesis and maintaining metabolic balance.
Intravenous infusion: 1.0-1.5 g amino acids/kg/day (11.8-17.6 mL/kg/day of 8.5% solution) via central line; rate not to exceed 0.1 g amino acids/kg/hour.
Intravenous: 500 mL to 2 L per day, infused at a rate of 20-40 mL/kg/day (0.5-1.5 g amino acids/kg/day) based on metabolic needs and tolerance.

Variable; amino acids have rapid distribution and metabolic half-lives of minutes to hours; terminal half-life of infused amino acid mixtures is approximately 1–2 hours for most components in patients with normal hepatic function
Not applicable; components are endogenous and rapidly cleared. Amino acids have short half-lives (e.g., alanine ~15 min; leucine ~30 min) and are continuously metabolized. Terminal elimination of water and electrolytes follows body fluid kinetics.
Renal elimination of infused amino acids as urea, ammonia, and other nitrogenous waste products; minimal biliary/fecal excretion (<2%)
Primarily renal; 90-100% eliminated as free amino acids, electrolytes, and water. Metabolized nitrogen is excreted as urea. Biliary/fecal: negligible (<2%).
