AMINOSYN 3.5% vs TRAVASOL 4.25% IN DEXTROSE 20% 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 20% is a parenteral nutrition solution providing amino acids and carbohydrates. Amino acids serve as substrates for protein synthesis, while dextrose supplies calories to prevent catabolism and promote anabolism. The solution corrects nitrogen balance and provides energy.
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 via central line. Typical adult dose: 500-1000 mL/day of TRAVASOL 4.25% in dextrose 20% (providing 4.25 g amino acids and 20 g dextrose per 100 mL) as part of total parenteral nutrition. Infusion rate: not to exceed 0.8 g/kg/h of amino acids. Individualize based on metabolic 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; components are endogenous nutrients. Dextrose half-life <15 min in normal renal function; amino acids have variable half-lives (minutes) due to rapid metabolism and incorporation. 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 excretion; amino acids are reabsorbed or metabolized, excess nitrogen excreted as urea (renal). Dextrose is metabolized to CO2 and water. No significant biliary/fecal elimination.
