HEPATAMINE 8% vs HEPATASOL 8%
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.
HEPATASOL 8% (amino acid injection) provides essential and non-essential amino acids to support protein synthesis and correct nitrogen balance in hepatic encephalopathy. It reduces plasma ammonia levels by promoting urea cycle activity and decreasing aromatic amino acids.
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 of 500 mL (40 g amino acids) over 3-4 hours, administered once daily or as directed by clinical response.

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.
Approximately 30-60 minutes for individual amino acids; clinical context: rapid clearance supports continuous infusion to maintain plasma levels.
Renal: negligible as intact amino acids; nitrogen waste (urea) excreted renally (80-90% of infused nitrogen). Biliary/fecal: <5%.
Renal: >95% of administered amino acids are reabsorbed and metabolized; negligible unchanged excretion. Biliary/fecal: <5%
