Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amino acids serve as substrates for protein synthesis and nitrogen balance; electrolytes maintain osmotic and acid-base balance.
Amino acids serve as substrates for protein synthesis and nitrogen balance; dextrose provides caloric energy via glycolysis and oxidative phosphorylation.
1-2 g/kg/day (0.1-0.2 g/kg/hour) IV via central line as continuous infusion.
Intravenous infusion: 1-1.5 g amino acids/kg/day (equivalent to 28-43 mL/kg/day of Aminosyn II 3.5% in D5W). Rate: infuse via central line at ≤100 mL/hour; peripheral line at ≤125 mL/hour. Adjust based on nitrogen balance and metabolic response.

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.
Not applicable as a mixture; individual components have varying half-lives. Dextrose: rapid distribution, half-life <1 hour. Amino acids: half-life of infused amino acids is short (minutes) due to metabolism.
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%).
Aminosyn II 3.5% in Dextrose 5% contains amino acids and dextrose. Amino acids are metabolized; negligible renal excretion of intact amino acids. Dextrose is metabolized. No biliary/fecal elimination of intact drug.
