AMINOSYN II 3.5% M IN PLASTIC CONTAINER vs TRAVASOL 5.5% IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn II 3.5% M is a crystalline amino acid solution that provides essential and non-essential amino acids for protein synthesis and nitrogen balance maintenance in patients unable to tolerate oral/enteral nutrition. The 'M' formulation includes electrolytes and trace elements. Amino acids are incorporated into endogenous proteins, serving as substrates for gluconeogenesis, oxidative metabolism, and neurotransmitter synthesis.
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 administration; typical adult dose is 1 to 2 g amino acids/kg/day, corresponding to 30 to 60 mL/kg/day of 3.5% solution; infusion rate not to exceed 0.1 g amino acids/kg/hour.
500 mL of 5.5% amino acid solution intravenously over 2-4 hours daily, titrated to nitrogen balance and metabolic tolerance.

Variable; amino acids have short plasma half-lives (minutes to hours) due to rapid cellular uptake and metabolism; no meaningful terminal half-life for the mixture.
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.
100% renal; amino acids are deaminated and metabolized to urea, which is excreted renally; minimal (<1%) biliary/fecal excretion.
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%).
