AMINOSYN 3.5% vs TRAVASOL 2.75% 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 2.75% in Dextrose 15% is a parenteral nutrition solution. Travassol provides amino acids for protein synthesis, while dextrose provides caloric energy. The mechanism involves intravenous administration to bypass gastrointestinal absorption, directly delivering substrates for metabolism and tissue repair.
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: 1000-2000 mL/day (providing 27.5 g amino acids and 150 g dextrose) at a rate not exceeding 4 mL/kg/hour.

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 direct drug; components have variable half-lives: amino acids are rapidly cleared (minutes to hours), dextrose is regulated by insulin (glucose half-life ~1-2 hours in euglycemia).
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 2.75% in dextrose 15% is a parenteral nutrition solution. The amino acids are metabolized and their nitrogen is primarily excreted as urea in urine (renal >90%), with minimal biliary or fecal elimination. Dextrose is metabolized to CO2 and water, exhaled via lungs and excreted renally.
