AMINOSYN II 4.25% M IN DEXTROSE 10% IN PLASTIC CONTAINER vs AMINOSYN II 7%
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn II 4.25% M in Dextrose 10% is a combination of amino acids and dextrose used for parenteral nutrition. Amino acids provide substrates for protein synthesis, while dextrose provides a source of calories. The amino acids undergo transamination, deamination, and incorporation into body proteins. Dextrose is metabolized via glycolysis, the Krebs cycle, and oxidative phosphorylation to produce ATP.
Aminosyn II 7% is a crystalline amino acid solution that provides essential and non-essential amino acids for protein synthesis, tissue repair, and maintenance of nitrogen balance. It acts as a substrate for protein synthesis and supports metabolic functions in patients unable to tolerate oral or enteral nutrition.
Intravenous infusion via central line. Adult dose: 500-2000 mL/day (equivalent to 21.25-85 g amino acids and 50-200 g dextrose) based on caloric and nitrogen requirements. Rate not to exceed 100 mL/hour initially, adjusted to maintain blood glucose <200 mg/dL.
Intravenous infusion; typical adult dose: 0.8-1.5 g amino acids/kg/day (11.4-21.4 mL/kg/day of 7% solution); rate not exceeding 0.1 g amino acids/kg/hour.

Amino acids: variable; individual amino acid half-lives range from minutes to hours; dextrose: 1-2 hours; clinical context: continuous infusion required to maintain stable plasma levels.
Not applicable; exogenous amino acids are rapidly cleared from plasma with a terminal half-life of 15-20 minutes for individual amino acids.
Renal: amino acids are metabolized and nitrogen is excreted primarily as urea (80-90%) and ammonia (minor); dextrose is fully metabolized to CO2 and water; negligible biliary/fecal elimination.
Renal as amino acids and metabolites; negligible biliary/fecal.
