AMINOSYN 8.5% (PH6) vs PREMASOL 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.
Provides essential amino acids for protein synthesis and maintenance of nitrogen balance.
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 g/kg/day intravenously as a continuous infusion or in divided doses; typical starting dose for adults with normal renal function: 1 g/kg/day.

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.
The terminal elimination half-life of infused amino acids is approximately 0.5-1 hour for most amino acids, reflecting rapid metabolism and distribution. Clinically, this supports continuous infusion to maintain plasma amino acid 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.
Amino acids in Premasol 10% are metabolized and the nitrogen is eliminated primarily as urea via renal excretion (80-90%). A small fraction is excreted in feces (5-10%) and as ammonia in urine. Biliary excretion is negligible.
