AMINOSYN 3.5% vs EPANOVA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn 3.5% is a crystalline amino acid solution that provides essential and non-essential amino acids for protein synthesis, thereby promoting nitrogen balance and tissue repair.
Omega-3 fatty acids (EPA and DHA) reduce hepatic very low-density lipoprotein (VLDL) synthesis and increase triglyceride clearance from circulating VLDL particles through activation of lipoprotein lipase.
Intravenous administration of 500 mL to 1000 mL per day as a 3.5% amino acid solution, typically infused at a rate of 1.25-2.5 mL/min (equivalent to 0.25-0.5 g amino acids/kg/day). Dose individualized based on nitrogen requirements and metabolic status.
4 g orally once daily as 4 capsules of 1 g each with food.

The plasma half-life of individual amino acids varies; for total amino acid mixture, the terminal elimination half-life is approximately 1-2 hours in patients with normal hepatic and renal function, reflecting rapid uptake into tissues and metabolism. This half-life is clinically relevant for continuous infusion scheduling.
Terminal elimination half-life approximately 89 hours (range 59–144 hr); allows weekly intramuscular dosing.
Amino acids are primarily eliminated via hepatic metabolism (deamination, transamination) and renal excretion. The renal excretion accounts for approximately 5-10% of the administered dose as unchanged amino acids; the majority is metabolized, and nitrogen is excreted as urea (80-90% of nitrogen) via urine, with minor fecal losses (<5%).
Primarily hepatic metabolism via omega-oxidation and subsequent conjugation; renal excretion of metabolites: ~15% unchanged in urine; biliary/fecal elimination accounts for ~85% as metabolites.
