AMINOSYN 10% vs AMINOSYN-RF 5.2%
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn 10% provides a mixture of essential and non-essential amino acids to support protein synthesis and maintain nitrogen balance in patients unable to tolerate adequate oral or enteral nutrition. Each amino acid serves as a substrate for protein synthesis, hormone production, and other metabolic processes.
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.
Intravenous infusion: 1-1.5 g/kg/day (as amino acids), typically 500 mL of 10% solution (50 g amino acids) over 8-12 hours daily.
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.

Amino acids: 0.5-1 hour for free amino acids; terminal half-life of infused nitrogen is approximately 2-4 hours; clinical context: reflects rapid uptake and metabolism.
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.
Renal (primarily as amino acids and metabolites); ~90% of infused amino nitrogen is excreted renally within 24-48 hours; <5% biliary/fecal.
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%).
