Amino acid solution providing essential and non-essential amino acids for protein synthesis and nitrogen balance in parenteral nutrition.
Total parenteral nutrition (TPN) provides essential nutrients (carbohydrates, proteins, fats, electrolytes, vitamins, trace elements) to maintain metabolic homeostasis when enteral nutrition is not possible or sufficient. It supports anabolism, prevents catabolism, and corrects deficiencies.
Intravenous infusion: initial dose 1.5 mL/kg/day (0.17 g amino acids/kg/day) increased by 0.5 mL/kg/day to 2.0-3.0 mL/kg/day (0.23-0.34 g amino acids/kg/day) maximum 3.5 mL/kg/day (0.4 g amino acids/kg/day). Infusion rate not to exceed 0.1 mL/kg/hour in neonates and 0.2 mL/kg/hour in older patients.
TPN (total parenteral nutrition) dosing is individualized. Typical adult: 1.0-2.0 g/kg/day amino acids, 1.0-2.0 g/kg/day lipids, and 5-15 g/day glucose (with insulin as needed). Infused via central line at 50-100 mL/hour initially, titrated to metabolic needs.

Variable, dependent on amino acid profile; net protein synthesis occurs over 4-6 hours post-infusion; no classical terminal half-life; clinical steady state achieved within 24-48 hours of continuous infusion.
Not applicable as a single entity; TPN is a composite. Individual components have variable half-lives: glucose ~2-4 hours, amino acids minutes to hours, lipids ~12-24 hours for triglycerides. Clinical context: continuous infusion maintains steady state.
Amino acids are metabolized via transamination and deamination; nitrogen is excreted renally as urea (75-90%), with minimal biliary/fecal elimination (<5%).
TPN components are metabolized and excreted via various routes. Amino acids are metabolized to urea (excreted renally) or incorporated into proteins. Dextrose is oxidized to CO2 and water (excreted via lungs and kidneys). Lipids are metabolized and stored; fatty acids are oxidized. Electrolytes and trace elements are primarily excreted renally. No single excretion route predominates; renal excretion accounts for ~50% of nitrogen waste, and CO2 is exhaled.
