AMINOSYN 3.5% vs TRAVASOL 2.75% IN DEXTROSE 25% 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% in Dextrose 25% is a parenteral nutrition solution providing amino acids and carbohydrates. The amino acids serve as substrates for protein synthesis, while dextrose provides a source of calories and spares protein catabolism. It does not have a direct pharmacological target but supports 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 administration only. Typical adult dose is 1 to 2 L per day, infused at a rate of 100 to 200 mL per hour, adjusted based on metabolic and fluid needs. Contains 2.75% amino acids and 25% dextrose.

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; amino acids have variable half-lives (minutes to hours), dextrose has a half-life of 1.5-2 hours in normoglycemic patients; 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: 100% as amino acids and dextrose metabolites; negligible biliary/fecal elimination.
