AMINOSYN 3.5% W/ DEXTROSE 5% IN PLASTIC CONTAINER vs AMINOSYN II 10% W/ ELECTROLYTES
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn 3.5% w/ Dextrose 5% provides essential and non-essential amino acids for protein synthesis and dextrose for caloric support, aiding in nitrogen balance and maintenance of lean body mass in parenteral nutrition.
Amino acids serve as substrates for protein synthesis and nitrogen balance; electrolytes maintain osmotic and acid-base balance.
Intravenous infusion. Adult dose: 500-1000 mL per day, infused at a rate not exceeding 100 mL/hour, adjusted based on metabolic requirements and tolerance.
1-2 g/kg/day (0.1-0.2 g/kg/hour) IV via central line as continuous infusion.

Not applicable as a single entity; amino acids and dextrose are endogenous substances. Metabolic half-life of infused amino acids ~10-30 min; dextrose ~15-20 min. Continuous infusion results in steady state.
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 excretion of amino acids and dextrose metabolites (CO2, water). Urea nitrogen accounts for ~80-90% of nitrogen excretion. Unchanged dextrose minimal (<1%). Biliary/fecal excretion negligible.
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%).
