AMINOSYN 8.5% vs AMINOSYN II 10% W/ ELECTROLYTES
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn 8.5% is a crystalline amino acid solution that provides a source of nitrogen and essential/non-essential amino acids for protein synthesis, tissue repair, and maintenance of nitrogen balance. It serves as a substrate for metabolic pathways, including gluconeogenesis and ketogenesis, and supports immune function and enzyme production.
Amino acids serve as substrates for protein synthesis and nitrogen balance; electrolytes maintain osmotic and acid-base balance.
Intravenous infusion: 1.0-1.5 g amino acids/kg/day (11.8-17.6 mL/kg/day of 8.5% solution) via central line; rate not to exceed 0.1 g amino acids/kg/hour.
1-2 g/kg/day (0.1-0.2 g/kg/hour) IV via central line as continuous infusion.

Variable; amino acids have rapid distribution and metabolic half-lives of minutes to hours; terminal half-life of infused amino acid mixtures is approximately 1–2 hours for most components in patients with normal hepatic function
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.
Renal elimination of infused amino acids as urea, ammonia, and other nitrogenous waste products; minimal biliary/fecal excretion (<2%)
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%).
