Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn II 4.25% w/ Electrolytes in Dextrose 25% is a parenteral nutrition formulation providing amino acids for protein synthesis and dextrose as a carbohydrate calorie source. The amino acids serve as substrates for protein synthesis, while dextrose provides glucose for cellular energy metabolism via glycolysis and the citric acid cycle. Electrolytes are included to maintain acid-base and fluid balance, and to support enzymatic functions and membrane potentials.
Travasol 5.5% is a crystalline amino acid solution that provides essential and nonessential amino acids for protein synthesis, maintaining nitrogen balance, and supporting metabolic functions in parenteral nutrition.
Intravenous infusion. Adult dose: 500 mL to 1000 mL per 24 hours, adjusted to meet protein and calorie requirements. Typical infusion rate: 1.5-2.0 mL/kg/hour, not exceeding 3.0 mL/kg/hour.
500 mL of 5.5% amino acid solution intravenously over 2-4 hours daily, titrated to nitrogen balance and metabolic tolerance.

Not applicable as a single entity; amino acids have rapid turnover (minutes to hours) with no terminal half-life. Dextrose has a half-life of 15-20 minutes under steady-state conditions.
Not applicable as individual amino acids have variable half-lives (minutes to hours). TRAVASOL is a mixture; the clinical context is continuous infusion to maintain plasma levels.
Amino acids are metabolized to urea (liver) and CO2; nitrogen is excreted renally as urea (80-90%), with minimal (<5%) biliary/fecal. Dextrose is metabolized to CO2 (exhaled) and water. Electrolytes are excreted renally proportional to intake and homeostasis.
Amino acids in TRAVASOL 5.5% are metabolized and nitrogen waste is excreted primarily via renal elimination (as urea, >90% of nitrogen). Fecal elimination is negligible (<2%).
