AMINOSYN II 5% IN DEXTROSE 25% IN PLASTIC CONTAINER vs HEPATAMINE 8%
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amino acids serve as substrates for protein synthesis and nitrogen balance; dextrose provides caloric energy. Dextrose stimulates insulin release, promoting cellular uptake of amino acids.
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 administration based on protein requirements: 1.0-2.0 g/kg/day amino acids, corresponding to 20-40 mL/kg/day of AMINOSYN II 5% in DEXTROSE 25%. Typical adult dose starts at 30-40 mL/hour, titrated to metabolic goals.
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.

Not applicable as a single entity; amino acids have rapid plasma clearance (t1/2 of minutes to hours) and dextrose is rapidly cleared (t1/2 ~1-2 hours). Clinical context: Continuous infusion maintains steady state.
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 primarily metabolized; nitrogen is excreted as urea (renal, ~85%) and ammonia (renal, ~2-5%); glucose is fully metabolized to CO2 and water (exhaled and renal); electrolytes are excreted renally. Less than 5% excreted unchanged renally.
Renal: negligible as intact amino acids; nitrogen waste (urea) excreted renally (80-90% of infused nitrogen). Biliary/fecal: <5%.
