AMINOSYN 3.5% vs TRAVASOL 4.25% SULFITE FREE W/ ELECTROLYTES IN DEXTROSE 15% 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 4.25% SULFITE FREE W/ ELECTROLYTES IN DEXTROSE 15% is a parenteral nutrition solution providing amino acids, dextrose, and electrolytes. The amino acids serve as substrates for protein synthesis; dextrose supplies caloric energy; electrolytes maintain acid-base balance and osmotic equilibrium.
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: 1-2 L/day as total parenteral nutrition; typical rate 100-125 mL/hour based on caloric and nitrogen needs.

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.
Not applicable as a single agent; components have varying half-lives: dextrose ~2 h (glucose), amino acids ~1-3 h (plasma clearance), electrolytes proportional to renal function
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: 100% (primarily as free water and electrolytes; dextrose is metabolized; amino acids are deaminated and urea is excreted renally)
