AMINOSYN 7% vs AMINOSYN II 10% IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn 7% provides a mixture of essential and nonessential amino acids, serving as substrates for protein synthesis, thereby supporting nitrogen balance and tissue repair. It acts as a source of caloric nitrogen in parenteral nutrition.
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: 500 mL to 2 L of 7% solution (35-140 g amino acids) per day by central or peripheral infusion, adjusted based on metabolic needs and nitrogen balance, usually infused at a rate not exceeding 0.1 g/kg/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.

Not applicable as a single entity; amino acids are utilized rapidly for protein synthesis and energy. Plasma amino acid levels decline with a terminal half-life of approximately 10-20 minutes post-infusion, reflecting rapid tissue uptake.
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.
Primarily renal elimination of infused amino acids as metabolic byproducts (urea, ammonia) and a small fraction of unchanged amino acids. Renal excretion accounts for >90% of elimination; negligible biliary/fecal.
Amino acids are metabolized; excess nitrogen is excreted renally as urea (70-90%) and to a lesser extent in feces (5-10%).
