AMINO ACIDS vs AMINOSYN-HF 8%
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amino acids are building blocks for protein synthesis and serve as precursors for neurotransmitters, hormones, and other nitrogenous compounds. They modulate nitrogen balance and support cellular repair and growth.
Aminosyn-HF 8% is a crystalline amino acid solution that provides essential and non-essential amino acids for protein synthesis, promoting nitrogen balance and tissue repair in patients unable to tolerate oral intake.
1-2 g/kg/day as continuous IV infusion or as a component of parenteral nutrition.
1-2 g/kg/day intravenously as total parenteral nutrition, typically administered as a continuous infusion over 24 hours.

Variable; endogenous amino acids: 10–30 min for clearance from plasma; administered doses: distribution half-life ~5–10 min, terminal elimination half-life ~15–30 min, reflecting rapid metabolic utilization and renal reabsorption.
Not applicable as amino acids are rapidly cleared; terminal half-life of infused amino acids is approximately 10-30 minutes.
Renal: >95% as amino acids and metabolites, primarily reabsorbed; <5% unchanged. Fecal/biliary: negligible (<1%).
Renal: >90% as amino acids and metabolites; fecal: <5%.
