AMINOSYN II 3.5% IN DEXTROSE 25% IN PLASTIC CONTAINER vs TRAVASOL 8.5% IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn II 3.5% in Dextrose 25% is a combination of amino acids and dextrose for parenteral nutrition. Amino acids provide nitrogen and essential substrates for protein synthesis, while dextrose provides a caloric source to prevent protein catabolism. The mechanism involves infusion into the bloodstream, bypassing gastrointestinal digestion, to maintain or restore nitrogen balance and provide energy.
TRAVASOL 8.5% is a crystalline amino acid solution that provides essential and non-essential amino acids for protein synthesis, tissue repair, and maintenance of nitrogen balance in patients unable to tolerate enteral nutrition.
Intravenous infusion. Amino acid dose based on protein requirements: 0.8-1.0 g/kg/day for stable patients, up to 1.5-2.0 g/kg/day for catabolic states. Dextrose dose based on caloric needs: typically 150-300 g/day. Infuse via central line at rates not exceeding 0.5 g/kg/hour dextrose. Typical starting rate: 50-100 mL/hr, titrated based on metabolic tolerance.
Intravenous administration as total parenteral nutrition: typical adult dose is 8.5% amino acid solution at 0.8-1.5 g protein/kg/day, infused continuously or cyclically.

Amino acids have variable half-lives (minutes to hours); dextrose has a plasma half-life of ~2 hours under euglycemic conditions. Clinically, continuous infusion maintains steady state.
Not applicable; constituent amino acids have individual half-lives (e.g., 0.5–2 hours for most L-amino acids) but overall elimination follows zero-order kinetics during continuous infusion. Clinically, infusion rate determines steady-state concentrations.
Renal excretion of amino acids as urea and ammonia; dextrose is metabolized to CO2 and water. Approximately 90% of infused amino nitrogen is recovered in urine as urea within 24 hours. Dextrose is completely metabolized.
Renal elimination of nitrogenous waste products (urea, ammonia) derived from amino acid metabolism; biliary/fecal excretion negligible. In healthy adults, >90% of infused amino nitrogen is ultimately excreted as urea in urine.
