AMINOSOL 5% vs AMINOSYN 3.5% IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyl 5% is a parenteral 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 feeding.
Aminosin 3.5% is a crystalline amino acid solution that provides essential and non-essential amino acids for protein synthesis, maintaining nitrogen balance, and supporting tissue repair and growth in patients unable to tolerate oral/enteral nutrition.
Intravenous infusion: 500 mL to 1 L of 5% solution over 8-12 hours, providing 25-50 g of amino acids. Maximum infusion rate: 0.1 g/kg/hour. Dose based on metabolic requirements and clinical status.
Intravenous infusion of 500 mL to 1 L daily, providing 3.5% amino acids (31.5 g protein per liter). Administer at a rate not exceeding 100 mL/hour initially, adjusted based on metabolic tolerance.

The half-life of infused amino acids is not defined as they are endogenous compounds. However, the nitrogen from amino acids has a biological half-life of approximately 6-18 hours, depending on metabolic activity. As part of total parenteral nutrition, the elimination half-life of infused amino acids is influenced by protein turnover and catabolism.
The terminal elimination half-life of infused amino acids is approximately 18-24 minutes, reflecting rapid clearance from plasma into tissues for protein synthesis.
Excretion of infused amino acids is primarily renal, with small amounts lost via feces and skin. Approximately 85-95% of the nitrogen load is excreted in urine as urea, ammonia, and other nitrogenous wastes. Less than 5% is eliminated in feces.
Amino acids are metabolized to urea and carbon dioxide; urea is excreted renally (90%) and to a lesser extent via sweat and feces (<10%).
