AMINOSYN II 10% IN PLASTIC CONTAINER vs HEPATAMINE 8%
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn II 10% is a crystalline amino acid solution that provides essential and nonessential amino acids for protein synthesis, maintenance of nitrogen balance, and tissue repair in parenteral nutrition.
HEPATAMINE 8% is a branched-chain amino acid (BCAA) solution that provides leucine, isoleucine, and valine to correct amino acid imbalances in hepatic encephalopathy. It reduces plasma aromatic amino acids (AAA) and increases BCAA, restoring the BCAA/AAA ratio, which decreases false neurotransmitter synthesis in the brain.
Intravenous infusion: 7-12 g amino acids per kg body weight per day (0.7-1.2 g/kg/day) for adults with normal renal function; typically administered as a 10% solution at a rate not exceeding 0.5 g amino acids/kg/hour.
Intravenous infusion: 125 mL/hr initially, titrate to achieve positive nitrogen balance; typical adult dose: 125 mL/hr to 250 mL/hr via central line, not to exceed 2 g protein equivalent per kg per day.

Variable depending on individual amino acids; typical of infused amino acids: 0.5-2 hours for most, with clinical context of continuous infusion achieving steady-state within 24 hours.
Variable; amino acids in HEPATAMINE 8% are cleared rapidly (t1/2 ~10-20 minutes for free amino acids) due to endogenous metabolism. In hepatic failure, half-life may be prolonged (patients with cirrhosis: up to 60 minutes for certain amino acids). Clinical context: supports continuous infusion for stable plasma levels.
Amino acids are metabolized; excess nitrogen is excreted renally as urea (70-90%) and to a lesser extent in feces (5-10%).
Renal: negligible as intact amino acids; nitrogen waste (urea) excreted renally (80-90% of infused nitrogen). Biliary/fecal: <5%.
