AMINOSYN 3.5% vs TRAVASOL 4.25% 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% in Dextrose 15% is a combination of amino acids and dextrose used for parenteral nutrition. Amino acids provide substrates for protein synthesis, while dextrose provides a source of calories. The mechanism involves intravenous administration bypassing the gastrointestinal tract to deliver nutrients directly into the bloodstream, supporting tissue repair, growth, and metabolic functions.
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; typical adult dose is 500 mL to 1000 mL per day, administered at a rate of 200 mL/hour, adjusted based on metabolic and fluid 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 entity; components have intrinsic half-lives. Amino acids: rapid distribution (minutes), with terminal elimination of metabolites (e.g., urea) ~4-8 hours. Dextrose: half-life ~1-2 hours in 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%).
TRAVASOL 4.25% IN DEXTROSE 15% (amino acids and dextrose) is a parenteral nutrition solution. Amino acids are metabolized to urea, which is excreted renally; dextrose is metabolized to CO2 and water. No significant biliary/fecal elimination.
