AMINOSYN II 8.5% vs TRAVASOL 10% W/O ELECTROLYTES
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn II 8.5% is a crystalline amino acid solution that provides essential and non-essential amino acids for protein synthesis when administered intravenously. It serves as a substrate for protein metabolism, promoting nitrogen retention and tissue repair.
Travasol 10% w/o electrolytes is a parenteral nutrition solution containing essential and non-essential amino acids. The amino acids provide substrates for protein synthesis, thereby supporting tissue repair, growth, and maintenance. The solution also provides a source of nitrogen and caloric replacement.
Intravenous infusion, typical adult dose is 1.0 to 1.5 g amino acids/kg/day, administered as part of total parenteral nutrition; rate not to exceed 0.1 g amino acids/kg/hour.
10% amino acid solution administered intravenously via central line at 0.5-1.0 g amino acids/kg/day, not to exceed 2.5 g/kg/day; typical infusion rate 50-125 mL/hr.

Variable; individual amino acids have half-lives ranging from minutes to hours. Clinical context: infusion rate and metabolic demand determine steady-state levels.
The terminal elimination half-life of infused amino acids is approximately 1-2 hours, reflecting rapid metabolism and clearance. Clinical context: Steady state is achieved within 1-2 hours of continuous infusion.
Amino acids are primarily eliminated via metabolism; less than 10% is excreted renally as free amino acids. No significant biliary or fecal excretion.
Amino acids are primarily metabolized; nitrogen is excreted renally as urea (∼85-90%), with small amounts in feces (∼5%) and minimal biliary elimination. Electrolytes are excreted renally, with excretion proportional to intake and renal function.
