AMINOSYN-HF 8% vs AMINOSYN-PF 7%
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Aminosyn-PF 7% is a crystalline amino acid solution that provides essential and non-essential amino acids for protein synthesis, thereby maintaining nitrogen balance and supporting tissue repair and growth in parenteral nutrition.
1-2 g/kg/day intravenously as total parenteral nutrition, typically administered as a continuous infusion over 24 hours.
Intravenous infusion; typical adult dose: 1-2 g amino acids/kg/day (e.g., 14-28 mL/kg/day for 7% solution) as part of parenteral nutrition. Infusion rate not to exceed 0.1 g amino acids/kg/hour.

Not applicable as amino acids are rapidly cleared; terminal half-life of infused amino acids is approximately 10-30 minutes.
As a mixture of amino acids, individual amino acids have half-lives ranging from minutes to hours; clinically, continuous infusion maintains steady state.
Renal: >90% as amino acids and metabolites; fecal: <5%.
Amino acids are primarily cleared by metabolism; less than 10% is excreted unchanged in urine.
