AMINOSYN 8.5% (PH6) vs AMINOSYN II 4.25% W/ ELECTROLYTES IN DEXTROSE 20% W/ CALCIUM IN PLASTIC CONTAINER
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.
Amino acids provide substrates for protein synthesis, counteract negative nitrogen balance, and maintain muscle mass. Dextrose supplies calories for energy metabolism, and electrolytes correct or prevent imbalances.
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.
1-2 L/day intravenously, infused at a rate of 1-2 mL/kg/hour (50-100 mL/hour) for a 70 kg adult, adjusted based on nitrogen 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.
Variable; amino acids have half-lives of minutes to hours depending on metabolic demand and renal function. Dextrose has a half-life of 15-20 minutes under normal conditions. In renal impairment, half-life of amino acid byproducts may prolong.
Primarily renal; elimination depends on metabolic utilization. Unused amino acids are deaminated and excreted as urea in urine (over 90%). Fecal elimination is negligible.
Urea (from amino acid metabolism) is excreted renally. Electrolytes and dextrose metabolites are eliminated via renal and respiratory routes. No significant biliary/fecal elimination.
