AMINOSYN II 5% vs TRAVASOL 10% W/O ELECTROLYTES
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn II 5% provides essential and non-essential amino acids for protein synthesis, serving as substrates for nitrogen balance and tissue repair. It supports metabolic processes in patients unable to maintain adequate nutrition enterally.
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 via central line, initial rate 50 mL/hour, increase by 25 mL/hour every 24 hours to goal rate of 1-2 mL/kg/hour (maximum 125 mL/hour). Total daily dose: 1.5-2.0 g/kg/day of amino acids (equivalent to 30-40 mL/kg/day).
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.

Not applicable as a single entity; individual amino acids have variable half-lives (e.g., 10-30 min for most), reflecting rapid distribution and metabolism. Clinical context: continuous infusion maintains steady state.
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.
Renal elimination of amino acids is minimal under normal conditions; excess amino acids are metabolized, and nitrogen is excreted as urea (renal, ~80-90%) and ammonia. Biliary/fecal excretion negligible.
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.
