AMINOSYN-RF 5.2% vs TRAVASOL 4.25% IN DEXTROSE 20% 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 20% is a parenteral nutrition solution providing amino acids and carbohydrates. Amino acids serve as substrates for protein synthesis, while dextrose supplies calories to prevent catabolism and promote anabolism. The solution corrects nitrogen balance and provides energy.
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 administration via central line. Typical adult dose: 500-1000 mL/day of TRAVASOL 4.25% in dextrose 20% (providing 4.25 g amino acids and 20 g dextrose per 100 mL) as part of total parenteral nutrition. Infusion rate: not to exceed 0.8 g/kg/h of amino acids. Individualize based on metabolic needs.

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; components are endogenous nutrients. Dextrose half-life <15 min in normal renal function; amino acids have variable half-lives (minutes) due to rapid metabolism and incorporation. Clinical context: continuous infusion maintains steady state.
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%).
Renal excretion; amino acids are reabsorbed or metabolized, excess nitrogen excreted as urea (renal). Dextrose is metabolized to CO2 and water. No significant biliary/fecal elimination.
