AMINOSYN 8.5% W/ELECTROLYTES 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% with Electrolytes is a crystalline amino acid solution used for parenteral nutrition. It provides essential and non-essential amino acids necessary for protein synthesis, tissue repair, and maintenance of nitrogen balance. Electrolytes are included to maintain acid-base balance and normal cellular function.
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: 500 mL to 1000 mL of 8.5% solution (42.5-85 g amino acids) once daily, infused at a rate not exceeding 100 mL/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.

The terminal elimination half-life of infused amino acids is approximately 0.5-1 hour for essential amino acids and 0.5-2 hours for non-essential amino acids, reflecting rapid distribution and metabolism in healthy adults. In renal or hepatic impairment, half-life may be prolonged.
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.
Amino acids are primarily eliminated via metabolism (deamination, transamination) and incorporation into proteins. Unmetabolized amino acids are excreted renally (approximately 5-10% of administered dose, depending on renal function and infusion rate). Fecal and biliary excretion are negligible (<1%).
Primarily renal; 90-100% eliminated as free amino acids, electrolytes, and water. Metabolized nitrogen is excreted as urea. Biliary/fecal: negligible (<2%).
