HEPATAMINE 8% vs TRAVASOL 5.5% W/O ELECTROLYTES
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.
TRAVASOL 5.5% W/O ELECTROLYTES is a crystalline amino acid solution that provides essential and non-essential amino acids for protein synthesis, tissue repair, and nitrogen balance in patients unable to tolerate enteral nutrition. It serves as a substrate for gluconeogenesis and other metabolic processes.
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, 500 mL to 2000 mL per day as a component of total parenteral nutrition (TPN), providing 5.5% amino acids. Rate should be individualized based on metabolic requirements and tolerance.

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.
Not applicable as a fixed drug; the clearance of infused amino acids follows saturable kinetics with a functional half-life of approximately 30-60 minutes for free amino acids in plasma, reflecting rapid uptake and metabolism. Clinical context: continuous infusion maintains steady-state levels.
Renal: negligible as intact amino acids; nitrogen waste (urea) excreted renally (80-90% of infused nitrogen). Biliary/fecal: <5%.
Primarily renal excretion of amino acids and metabolites; approximately 70-80% of infused amino acids are converted to urea and excreted in urine, with the remainder undergoing metabolism or incorporation into body proteins. Biliary/fecal excretion is negligible.
