AMINOSYN 10% (PH6) vs AMINOSYN-PF 7%
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn 10% is a parenteral amino acid solution that provides essential and non-essential amino acids for protein synthesis, helping to maintain nitrogen balance and support tissue repair and growth in patients unable to receive adequate nutrition enterally.
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.
Intravenous infusion: 1 to 1.5 g/kg/day (equivalent to 10 to 15 mL/kg/day of 10% solution) for adult patients with normal nutritional status; adjust based on metabolic needs.
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.

The terminal elimination half-life of individual amino acids varies (1–4 hours) depending on metabolic demand and renal function. For the amino acid mixture, the effective half-life is approximately 2 hours in patients with normal renal function. This short half-life necessitates continuous or frequent infusion to maintain stable plasma levels.
As a mixture of amino acids, individual amino acids have half-lives ranging from minutes to hours; clinically, continuous infusion maintains steady state.
Amino acids from Aminosyn 10% are primarily utilized for protein synthesis and metabolic processes. Excess nitrogen is eliminated via the kidneys as urea (renal elimination accounts for >90% of nitrogen excretion). Minimal biliary/fecal elimination (<5%) occurs via unabsorbed amino acids in patients with malabsorption. In renal impairment, elimination is reduced.
Amino acids are primarily cleared by metabolism; less than 10% is excreted unchanged in urine.
