AMINOSYN 5% vs AMINOSYN II 3.5% IN DEXTROSE 25% IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn 5% provides essential and nonessential amino acids for protein synthesis, maintaining nitrogen balance, and supporting tissue repair in patients unable to tolerate oral intake.
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.
Intravenous infusion; 500 mL of 5% solution (25 g protein equivalent) per day, typically at a rate not exceeding 100 mL/hour. Dosage individualized based on protein requirements and metabolic status.
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.

Not applicable as a drug; amino acids have rapid turnover with half-lives varying from minutes to hours depending on the individual amino acid.
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.
Amino acids are metabolized; nitrogen is excreted renally as urea (80-90%) and in feces (5-10%).
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.
