Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn 8.5% (pH 6) provides a mixture of essential and nonessential amino acids for protein synthesis and nitrogen balance maintenance in patients unable to tolerate oral or enteral nutrition.
Aminogen (amino acids) provide substrate for protein synthesis; dextrose provides caloric energy; electrolytes maintain acid-base and fluid balance; phosphate is essential for cellular metabolism and buffering.
1-1.5 g amino acids/kg/day intravenously, typically 500 mL of a 8.5% solution (42.5 g amino acids) infused over 8-24 hours.
Intravenous infusion; typical adult dose: 1-1.5 g amino acids/kg/day, with dextrose providing 10% final concentration. Adjusted to meet protein and caloric needs.

Not applicable as a fixed value; elimination half-life of individual amino acids varies (minutes to hours) and is dependent on metabolic demand and renal function.
Amino acids have a terminal elimination half-life of approximately 1.5–2 hours in healthy adults, reflecting rapid metabolic clearance. In renal impairment, half-life may be prolonged due to accumulation of nitrogenous waste.
Primarily renal; elimination depends on metabolic utilization. Unused amino acids are deaminated and excreted as urea in urine (over 90%). Fecal elimination is negligible.
The components of AMINOSYN II (amino acids) and dextrose are primarily metabolized; excess nitrogen is excreted renally as urea. Dextrose is completely oxidized. Electrolytes are excreted mainly renally. Biliary/fecal elimination is negligible for amino acids and dextrose (<2%).
