AMINOSYN II 3.5% IN DEXTROSE 25% IN PLASTIC CONTAINER vs TRAVASOL 5.5% 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 5.5% is a crystalline amino acid solution that provides essential and nonessential amino acids for protein synthesis, maintaining nitrogen balance, and supporting metabolic functions in parenteral 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.
500 mL of 5.5% amino acid solution intravenously over 2-4 hours daily, titrated to nitrogen balance and metabolic tolerance.

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 as individual amino acids have variable half-lives (minutes to hours). TRAVASOL is a mixture; the clinical context is continuous infusion to maintain plasma levels.
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.
Amino acids in TRAVASOL 5.5% are metabolized and nitrogen waste is excreted primarily via renal elimination (as urea, >90% of nitrogen). Fecal elimination is negligible (<2%).
