HEPATAMINE 8% vs PREMASOL 6% IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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 amino acid solution providing essential and non-essential amino acids for protein synthesis, nitrogen balance, and maintenance of lean body mass. Amino acids are actively transported into cells and incorporated into proteins; also serves as a caloric source.
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.
Intravenous infusion: 1 to 1.5 g/kg/day (amino acids) as part of total parenteral nutrition; typically 500 mL to 1000 mL per day, infused over 12-24 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 have rapid plasma clearance; elimination half-life varies from minutes to hours depending on individual amino acid; clinically, infused amino acids are cleared within 2-4 hours after infusion cessation.
Renal: negligible as intact amino acids; nitrogen waste (urea) excreted renally (80-90% of infused nitrogen). Biliary/fecal: <5%.
Renal elimination of amino acids and metabolites; complete metabolism with nitrogen excretion as urea in urine; minimal biliary/fecal excretion.
