AMINOSYN-RF 5.2% vs TRAVASOL 4.25% IN DEXTROSE 25% IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn-RF 5.2% is an amino acid solution that provides essential and nonessential amino acids for protein synthesis, primarily in patients with renal impairment. It is designed to reduce ureagenesis and nitrogenous waste accumulation by supplying a higher proportion of essential amino acids while limiting total nitrogen load.
TRAVASOL 4.25% IN DEXTROSE 25% provides crystalline amino acids and dextrose for parenteral nutrition. Amino acids serve as substrates for protein synthesis, while dextrose provides a carbohydrate source for energy. The formulation supplies essential and nonessential amino acids to maintain nitrogen balance and support tissue repair and growth.
1-1.5 g/kg/day intravenously as a continuous infusion, typically 500 mL to 1000 mL/day depending on amino acid requirements and fluid status. Dose is expressed as grams of amino acids per kg of ideal body weight per day.
Intravenous infusion; usual adult dose provides 0.5-2.0 g amino acids/kg/day, with dextrose providing 2-5 mg/kg/min; rate adjusted according to metabolic and fluid needs; typically infused over 24 hours via central line.

The terminal elimination half-life of infused amino acids is approximately 10–20 minutes, reflecting rapid distribution and metabolism; clinical context: continuous infusion maintains steady state within 30 minutes.
Not applicable as TRAVASOL 4.25% IN DEXTROSE 25% is a nutrient solution, not a drug with a defined elimination half-life.
Primarily renal; >95% of infused essential amino acids and small peptides are reabsorbed; excess amino acids are deaminated and nitrogen excreted as urea in urine (renal clearance of urea). Biliary/fecal excretion is negligible (<2%).
The amino acids and dextrose are completely metabolized; no significant renal or biliary excretion of intact product.
