AMINOSYN 8.5% (PH6) 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% (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 serve as substrates for protein synthesis and nitrogen balance; dextrose provides caloric energy via glycolysis and oxidative phosphorylation.
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: 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.

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.
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.
Primarily renal; elimination depends on metabolic utilization. Unused amino acids are deaminated and excreted as urea in urine (over 90%). Fecal elimination is negligible.
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.
