AMINOSYN 8.5% W/ELECTROLYTES vs AMINOSYN II 10% IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn 8.5% with Electrolytes is a crystalline amino acid solution used for parenteral nutrition. It provides essential and non-essential amino acids necessary for protein synthesis, tissue repair, and maintenance of nitrogen balance. Electrolytes are included to maintain acid-base balance and normal cellular function.
Aminosyn II 10% is a crystalline amino acid solution that provides essential and nonessential amino acids for protein synthesis, maintenance of nitrogen balance, and tissue repair in parenteral nutrition.
Intravenous infusion: 500 mL to 1000 mL of 8.5% solution (42.5-85 g amino acids) once daily, infused at a rate not exceeding 100 mL/hour.
Intravenous infusion: 7-12 g amino acids per kg body weight per day (0.7-1.2 g/kg/day) for adults with normal renal function; typically administered as a 10% solution at a rate not exceeding 0.5 g amino acids/kg/hour.

The terminal elimination half-life of infused amino acids is approximately 0.5-1 hour for essential amino acids and 0.5-2 hours for non-essential amino acids, reflecting rapid distribution and metabolism in healthy adults. In renal or hepatic impairment, half-life may be prolonged.
Variable depending on individual amino acids; typical of infused amino acids: 0.5-2 hours for most, with clinical context of continuous infusion achieving steady-state within 24 hours.
Amino acids are primarily eliminated via metabolism (deamination, transamination) and incorporation into proteins. Unmetabolized amino acids are excreted renally (approximately 5-10% of administered dose, depending on renal function and infusion rate). Fecal and biliary excretion are negligible (<1%).
Amino acids are metabolized; excess nitrogen is excreted renally as urea (70-90%) and to a lesser extent in feces (5-10%).
