Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amino acids serve as substrates for protein synthesis and nitrogen balance; electrolytes maintain osmotic and acid-base balance.
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.
1-2 g/kg/day (0.1-0.2 g/kg/hour) IV via central line as continuous infusion.
500 mL of 5.5% amino acid solution intravenously over 2-4 hours daily, titrated to nitrogen balance and metabolic tolerance.

The terminal elimination half-life of individual amino acids varies but is generally short (range 0.5–2 hours) due to rapid uptake and metabolism. Clinically, the half-life of infused amino acids is not a relevant parameter for dosing; rather, infusion rate is adjusted to maintain nitrogen balance.
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 primarily metabolized to urea and other nitrogenous waste products, which are excreted renally (90-95% of total nitrogen excreted as urea). Unmetabolized amino acids in plasma are also filtered and reabsorbed by the kidneys; negligible amounts are excreted unchanged (<5%). Biliary/fecal excretion is minimal (<2%).
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%).
