AMINOSYN II 3.5% M IN PLASTIC CONTAINER vs HEPATASOL 8%
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn II 3.5% M is a crystalline amino acid solution that provides essential and non-essential amino acids for protein synthesis and nitrogen balance maintenance in patients unable to tolerate oral/enteral nutrition. The 'M' formulation includes electrolytes and trace elements. Amino acids are incorporated into endogenous proteins, serving as substrates for gluconeogenesis, oxidative metabolism, and neurotransmitter synthesis.
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 administration; typical adult dose is 1 to 2 g amino acids/kg/day, corresponding to 30 to 60 mL/kg/day of 3.5% solution; infusion rate not to exceed 0.1 g amino acids/kg/hour.
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 have short plasma half-lives (minutes to hours) due to rapid cellular uptake and metabolism; no meaningful terminal half-life for the mixture.
Approximately 30-60 minutes for individual amino acids; clinical context: rapid clearance supports continuous infusion to maintain plasma levels.
100% renal; amino acids are deaminated and metabolized to urea, which is excreted renally; minimal (<1%) biliary/fecal excretion.
Renal: >95% of administered amino acids are reabsorbed and metabolized; negligible unchanged excretion. Biliary/fecal: <5%
