FREAMINE II 8.5% vs FREAMINE III 8.5%
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
FREAMINE II 8.5% is a crystalline amino acid solution that provides essential and non-essential amino acids for protein synthesis, supporting nitrogen balance and tissue repair in patients unable to tolerate oral or enteral nutrition.
FREAMINE III 8.5% is a crystalline amino acid solution that provides essential and non-essential amino acids for protein synthesis, nitrogen balance maintenance, and tissue repair. It acts as a substrate for protein anabolism in patients unable to tolerate adequate oral or enteral intake.
Intravenous infusion: 0.8-1.5 g amino acids/kg/day. Typical dose is 500-1000 mL per day (42.5-85 g amino acids). Infusion rate should not exceed 0.1 g amino acids/kg/hour.
Intravenous infusion; typical adult dose is 0.8-1.5 g amino acids/kg/day (equivalent to 9.4-17.6 mL/kg/day of Freamine III 8.5%). Initiate at lower end and titrate to metabolic needs. Administer via central or peripheral line with dextrose and electrolytes as part of parenteral nutrition.

Not applicable as a mixture; individual amino acids have variable half-lives (e.g., essential amino acids ~1-3 hours). Clinical context: continuous infusion required to maintain plasma levels.
Terminal elimination half-life of infused amino acids is approximately 15-30 minutes for most, but albumin synthesis half-life is 20-22 days; clinical context: continuous infusion needed for nitrogen balance.
Renal elimination of nitrogenous waste products (urea) derived from amino acid metabolism; <5% excreted unchanged in urine. No significant biliary or fecal elimination.
Renal: 90-95% of infused amino acids are reabsorbed; excess nitrogen excreted as urea (80-90% of nitrogen load) and ammonia (<10%). Biliary/fecal: negligible (<5%).
