AMINOSYN 7% vs AMINOSYN II 4.25% IN DEXTROSE 25% 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.
Aminosin II 4.25% in Dextrose 25% provides essential amino acids and dextrose for parenteral nutrition. Amino acids serve as building blocks for protein synthesis, while dextrose supplies a source of calories to prevent catabolism. The combination aims to maintain nitrogen balance and support metabolic functions.
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.
Administer as a continuous intravenous infusion. Typical adult dose: 1.0-1.5 g amino acids/kg/day (equivalent to approximately 23-35 mL/kg/day of AMINOSYN II 4.25% in DEXTROSE 25%) via central venous line. Adjust based on metabolic needs and tolerance.

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.
Amino acids: 0.5-2 hours; dextrose: 1-4 hours in non-diabetic patients; context: reflects rapid uptake and metabolism
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.
Renal: >90% as amino acids and metabolites; biliary/fecal: minimal (<2%)
