FREAMINE 8.5% vs FREAMINE III 10%
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
FREAMINE 8.5% is a crystalline amino acid solution that provides essential and nonessential amino acids for protein synthesis, maintenance of nitrogen balance, and tissue repair in patients unable to tolerate oral or enteral nutrition.
FREAMINE III 10% is a parenteral amino acid solution that provides essential and non-essential amino acids for protein synthesis and nitrogen balance in patients unable to tolerate oral or enteral nutrition.
1 to 2 g/kg/day intravenously, typical adult dose 70-140 g/day (800-1650 mL of 8.5% solution), infused at a rate not exceeding 0.1 g/kg/hour
Intravenous administration as part of parenteral nutrition. Typical adult dose: 0.8-1.5 g amino acids/kg/day, infused continuously over 24 hours.

The terminal elimination half-life of infused amino acids is not conventionally defined as it depends on metabolic utilization. For most amino acids, plasma clearance is rapid (minutes to hours) with a pseudo-half-life of approximately 15-30 minutes for the initial distribution phase. Clinical context: half-life is irrelevant since amino acids are continuously metabolized and incorporated into proteins.
Component-dependent: free amino acids t1/2 ~15–30 min; urea cycle intermediates ca. 2 h.
Amino acids from FREAMINE 8.5% are primarily metabolized via deamination and transamination pathways, with nitrogen waste excreted renally as urea (approx 80-90% of administered nitrogen). A small fraction is excreted via feces as unabsorbed amino acids (less than 5%). Biliary excretion is negligible.
Primarily renal; amino acids and nitrogenous waste products are excreted as urea and other metabolites. <5% fecal.
