AMINOSYN 3.5% vs TRAVASOL 2.75% SULFITE FREE W/ ELECTROLYTES IN DEXTROSE 5% IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn 3.5% is a crystalline amino acid solution that provides essential and non-essential amino acids for protein synthesis, thereby promoting nitrogen balance and tissue repair.
TRAVASOL 2.75% SULFITE FREE W/ ELECTROLYTES IN DEXTROSE 5% is a crystalline amino acid solution combined with electrolytes and dextrose. Amino acids provide substrates for protein synthesis, dextrose supplies calories to minimize protein catabolism, and electrolytes maintain acid-base and electrolyte balance.
Intravenous administration of 500 mL to 1000 mL per day as a 3.5% amino acid solution, typically infused at a rate of 1.25-2.5 mL/min (equivalent to 0.25-0.5 g amino acids/kg/day). Dose individualized based on nitrogen requirements and metabolic status.
Intravenous infusion: 500-1000 mL administered over 1-2 hours per day, adjusted based on electrolyte and fluid requirements. Typical adult dose provides 2.75% amino acids and 5% dextrose with electrolytes.

The plasma half-life of individual amino acids varies; for total amino acid mixture, the terminal elimination half-life is approximately 1-2 hours in patients with normal hepatic and renal function, reflecting rapid uptake into tissues and metabolism. This half-life is clinically relevant for continuous infusion scheduling.
Amino acids: 15-30 min (rapid redistribution). Dextrose: 1-2 h. Clinical context: continuous infusion maintains steady state.
Amino acids are primarily eliminated via hepatic metabolism (deamination, transamination) and renal excretion. The renal excretion accounts for approximately 5-10% of the administered dose as unchanged amino acids; the majority is metabolized, and nitrogen is excreted as urea (80-90% of nitrogen) via urine, with minor fecal losses (<5%).
Renal: >95% of infused amino acids and dextrose metabolites excreted as urea, CO2, and water. Biliary/fecal: negligible.
