AMINOSYN 8.5% W/ELECTROLYTES vs TRAVASOL 5.5% 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% is a crystalline amino acid solution that provides essential and nonessential amino acids for protein synthesis, maintaining nitrogen balance, and supporting metabolic functions in parenteral nutrition.
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.
500 mL of 5.5% amino acid solution intravenously over 2-4 hours daily, titrated to nitrogen balance and metabolic 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 as individual amino acids have variable half-lives (minutes to hours). TRAVASOL is a mixture; the clinical context is continuous infusion to maintain plasma levels.
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%).
Amino acids in TRAVASOL 5.5% are metabolized and nitrogen waste is excreted primarily via renal elimination (as urea, >90% of nitrogen). Fecal elimination is negligible (<2%).
