AMINOSYN 4.25% W/ DEXTROSE 25% IN PLASTIC CONTAINER vs AMINOSYN II 3.5%
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn 4.25% w/ Dextrose 25% provides amino acids for protein synthesis and dextrose as a caloric source, supporting nitrogen balance and energy requirements in parenteral nutrition.
Amino acids serve as substrates for protein synthesis, providing essential and non-essential nitrogen sources for anabolism in patients unable to tolerate oral or enteral nutrition.
Adults: 1-3 L/day intravenously through central line. Infusion rate initially 50-100 mL/hour, titrate to achieve protein and calorie requirements.
Intravenous infusion of 250-500 mL/day (8.75-17.5 g amino acids) as a component of parenteral nutrition; rate up to 125 mL/hour; titrate based on metabolic response.

Amino acids: 10-30 min (rapid distribution). Dextrose: glucose half-life ~1.5-2 h in euglycemia; prolonged in renal impairment. Clinically, continuous infusion maintains steady state without significant accumulation.
Terminal elimination half-life of individual amino acids ranges from 10 to 30 minutes for most, with glutamine and arginine slightly longer (30–45 min). No defined half-life for the mixture; clinically, steady-state achieved in 2–3 hours with continuous infusion.
Amino acids are metabolized; nitrogen waste is excreted renally as urea. Dextrose is metabolized to CO2 and water. Renal excretion accounts for >95% of nitrogen elimination. Minimal biliary/fecal elimination.
Renal: 95% of infused amino acids are reabsorbed; excess amino acids are deaminated and urea is excreted renally. Fecal/Biliary: negligible (<1%).
