AMINOSYN II 3.5% M vs TRAVASOL 5.5% W/ ELECTROLYTES
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 5.5% W/ ELECTROLYTES is a parenteral nutritional solution providing amino acids and electrolytes. Amino acids serve as substrates for protein synthesis, while electrolytes maintain osmotic balance and support cellular functions. The solution bypasses gastrointestinal absorption, directly entering the bloodstream.
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: 25-40 mL/kg/day (1.5-2.2 g amino acids/kg/day) as total parenteral nutrition; rate adjusted based on metabolic and clinical response.

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.
2–3 hours for infused amino acids; clinical context: rapid clearance in normal renal function, prolonged in renal impairment.
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.
Renal, >95% as amino acids and metabolites; negligible biliary/fecal.
