Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amino acids serve as substrates for protein synthesis and nitrogen balance; dextrose provides caloric energy. Dextrose stimulates insulin release, promoting cellular uptake of amino acids.
Provides essential amino acids for protein synthesis and maintenance of nitrogen balance.
Intravenous administration based on protein requirements: 1.0-2.0 g/kg/day amino acids, corresponding to 20-40 mL/kg/day of AMINOSYN II 5% in DEXTROSE 25%. Typical adult dose starts at 30-40 mL/hour, titrated to metabolic goals.
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 single entity; amino acids have rapid plasma clearance (t1/2 of minutes to hours) and dextrose is rapidly cleared (t1/2 ~1-2 hours). Clinical context: Continuous infusion maintains steady 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 primarily metabolized; nitrogen is excreted as urea (renal, ~85%) and ammonia (renal, ~2-5%); glucose is fully metabolized to CO2 and water (exhaled and renal); electrolytes are excreted renally. Less than 5% excreted unchanged renally.
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.
