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; dextrose provides caloric energy via glycolysis and oxidative phosphorylation.
Provides essential amino acids for protein synthesis and maintenance of nitrogen balance.
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.
1-2 g/kg/day intravenously as a continuous infusion or in divided doses; typical starting dose for adults with normal renal function: 1 g/kg/day.

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.
The terminal elimination half-life of infused amino acids is approximately 0.5-1 hour for most amino acids, reflecting rapid metabolism and distribution. Clinically, this supports continuous infusion to maintain plasma amino acid levels.
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.
Amino acids in Premasol 10% are metabolized and the nitrogen is eliminated primarily as urea via renal excretion (80-90%). A small fraction is excreted in feces (5-10%) and as ammonia in urine. Biliary excretion is negligible.
