AMINOSYN 3.5% W/ DEXTROSE 5% IN PLASTIC CONTAINER vs AMINOSYN II 3.5% M
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn 3.5% w/ Dextrose 5% provides essential and non-essential amino acids for protein synthesis and dextrose for caloric support, aiding in nitrogen balance and maintenance of lean body mass in parenteral nutrition.
Provides essential and nonessential amino acids for protein synthesis, serving as substrates for anabolic processes in parenteral nutrition.
Intravenous infusion. Adult dose: 500-1000 mL per day, infused at a rate not exceeding 100 mL/hour, adjusted based on metabolic requirements and tolerance.
Intravenous infusion of 1.2 to 2.2 g amino acids per kg per day, adjusted to meet metabolic and nutritional requirements. Typical adult dose: initial infusion rate of 50 mL/hour, increasing to 125 mL/hour (4.4 g amino acids per hour) based on tolerance. Not for direct peripheral administration without supplementation of electrolytes and/or dextrose.

Not applicable as a single entity; amino acids and dextrose are endogenous substances. Metabolic half-life of infused amino acids ~10-30 min; dextrose ~15-20 min. Continuous infusion results in steady state.
The terminal elimination half-life of amino acids from the infusion mixture is not uniformly defined; however, individual amino acids have half-lives ranging from 10 to 30 minutes. For the mixture, the effective half-life is clinically considered to be approximately 1-2 hours, reflecting rapid metabolic clearance. In renal impairment, the half-life may be prolonged due to reduced urea clearance.
Renal excretion of amino acids and dextrose metabolites (CO2, water). Urea nitrogen accounts for ~80-90% of nitrogen excretion. Unchanged dextrose minimal (<1%). Biliary/fecal excretion negligible.
Aminosyn II 3.5% M is a crystalline amino acid solution. Amino acids are primarily eliminated by metabolic utilization for protein synthesis and energy production. Excess amino acids undergo deamination, with nitrogen excreted as urea in urine via renal route. Fecal and biliary excretion are negligible. Approximately 80-90% of infused nitrogen is recovered as urea in urine in patients with normal renal function.
