AMINOSYN 3.5% IN PLASTIC CONTAINER vs AMINOSYN-RF 5.2%
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosin 3.5% is a crystalline amino acid solution that provides essential and non-essential amino acids for protein synthesis, maintaining nitrogen balance, and supporting tissue repair and growth in patients unable to tolerate oral/enteral nutrition.
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 of 500 mL to 1 L daily, providing 3.5% amino acids (31.5 g protein per liter). Administer at a rate not exceeding 100 mL/hour initially, adjusted based on metabolic tolerance.
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.

The terminal elimination half-life of infused amino acids is approximately 18-24 minutes, reflecting rapid clearance from plasma into tissues for protein synthesis.
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.
Amino acids are metabolized to urea and carbon dioxide; urea is excreted renally (90%) and to a lesser extent via sweat and feces (<10%).
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%).
