AMINOSYN II 4.25% IN DEXTROSE 10% IN PLASTIC CONTAINER vs PREMASOL 10% IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn II 4.25% 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 to prevent catabolism. The mechanism involves intravenous administration bypassing gastrointestinal tract, directly providing essential and non-essential amino acids for anabolism and energy in the form of glucose.
Provides essential amino acids for protein synthesis and maintenance of nitrogen balance.
Intravenous infusion. Typical adult dose: 500 mL to 1000 mL per day by central line, providing 4.25% amino acids and 10% dextrose. Infusion rate typically 1-2 mL/min initially, adjusted to provide 1-1.5 g/kg/day of amino acids and 3-4 g/kg/day of dextrose.
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 agent; amino acids have distribution half-life of 15-30 min; dextrose has elimination half-life of 1.5-2.5 hours depending on metabolic state.
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 to urea and other nitrogenous wastes; renal excretion of metabolites accounts for >90% of nitrogen elimination, with <5% excreted unchanged in urine. Dextrose is fully metabolized to CO2 and water.
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.
