Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn II 10% is a crystalline amino acid solution that provides essential and nonessential amino acids for protein synthesis, maintenance of nitrogen balance, and tissue repair in parenteral nutrition.
Provides essential amino acids for protein synthesis and maintenance of nitrogen balance.
Intravenous infusion: 7-12 g amino acids per kg body weight per day (0.7-1.2 g/kg/day) for adults with normal renal function; typically administered as a 10% solution at a rate not exceeding 0.5 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 depending on individual amino acids; typical of infused amino acids: 0.5-2 hours for most, with clinical context of continuous infusion achieving steady-state within 24 hours.
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.
Amino acids are metabolized; excess nitrogen is excreted renally as urea (70-90%) and to a lesser extent in feces (5-10%).
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.
