AMINOSYN 8.5% W/ELECTROLYTES vs TRAVASOL 5.5% W/ ELECTROLYTES
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% W/ ELECTROLYTES is a parenteral nutritional solution providing amino acids and electrolytes. Amino acids serve as substrates for protein synthesis, while electrolytes maintain osmotic balance and support cellular functions. The solution bypasses gastrointestinal absorption, directly entering the bloodstream.
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 infusion: 25-40 mL/kg/day (1.5-2.2 g amino acids/kg/day) as total parenteral nutrition; rate adjusted based on metabolic and clinical response.

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.
2–3 hours for infused amino acids; clinical context: rapid clearance in normal renal function, prolonged in renal impairment.
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%).
Renal, >95% as amino acids and metabolites; negligible biliary/fecal.
