Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn II 3.5% M is a crystalline amino acid solution that provides essential and non-essential amino acids for protein synthesis and nitrogen balance maintenance in patients unable to tolerate oral/enteral nutrition. The 'M' formulation includes electrolytes and trace elements. Amino acids are incorporated into endogenous proteins, serving as substrates for gluconeogenesis, oxidative metabolism, and neurotransmitter synthesis.
Provides essential amino acids for protein synthesis and maintenance of nitrogen balance.
Intravenous administration; typical adult dose is 1 to 2 g amino acids/kg/day, corresponding to 30 to 60 mL/kg/day of 3.5% solution; infusion rate not to exceed 0.1 g amino acids/kg/hour.
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.

Variable; amino acids have short plasma half-lives (minutes to hours) due to rapid cellular uptake and metabolism; no meaningful terminal half-life for the mixture.
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.
100% renal; amino acids are deaminated and metabolized to urea, which is excreted renally; minimal (<1%) biliary/fecal excretion.
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.
