Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Provides essential and nonessential amino acids for protein synthesis, serving as substrates for anabolic processes in parenteral nutrition.
TRAVASOL 8.5% W/O ELECTROLYTES provides amino acids for protein synthesis, serving as a source of nitrogen and essential amino acids to support anabolism and prevent catabolism in patients unable to tolerate oral or enteral nutrition.
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.
Intravenous infusion; 500 mL to 1 L per day, administered at a rate of 100-200 mL/hour. Dosage depends on protein and calorie requirements, typically 0.8-1.5 g/kg/day of amino acids.

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.
Not applicable as a single value; amino acids have variable half-lives (minutes to hours) depending on individual metabolic demand and plasma concentration; continuous infusion achieves steady state rapidly.
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.
Primarily eliminated via metabolic pathways (hepatic deamination and transamination) with nitrogenous waste excreted renally as urea; negligible biliary/fecal excretion of unchanged amino acids.
