AMINOSYN 8.5% (PH6) vs AMINOSYN II 4.25% M IN DEXTROSE 10% 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.
Aminosyn II 4.25% M in Dextrose 10% is a combination of amino acids and dextrose used for parenteral nutrition. Amino acids provide substrates for protein synthesis, while dextrose provides a source of calories. The amino acids undergo transamination, deamination, and incorporation into body proteins. Dextrose is metabolized via glycolysis, the Krebs cycle, and oxidative phosphorylation to produce ATP.
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 via central line. Adult dose: 500-2000 mL/day (equivalent to 21.25-85 g amino acids and 50-200 g dextrose) based on caloric and nitrogen requirements. Rate not to exceed 100 mL/hour initially, adjusted to maintain blood glucose <200 mg/dL.

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: variable; individual amino acid half-lives range from minutes to hours; dextrose: 1-2 hours; clinical context: continuous infusion required to maintain stable plasma levels.
Primarily renal; elimination depends on metabolic utilization. Unused amino acids are deaminated and excreted as urea in urine (over 90%). Fecal elimination is negligible.
Renal: amino acids are metabolized and nitrogen is excreted primarily as urea (80-90%) and ammonia (minor); dextrose is fully metabolized to CO2 and water; negligible biliary/fecal elimination.
