AMINOSYN 8.5% vs AMINOSYN II 3.5% IN DEXTROSE 5% IN PLASTIC CONTAINER
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; dextrose provides caloric energy via glycolysis and oxidative phosphorylation.
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.
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.

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
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.
Renal elimination of infused amino acids as urea, ammonia, and other nitrogenous waste products; minimal biliary/fecal excretion (<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.
