AMINOSOL 5% vs PROCALAMINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyl 5% is a parenteral amino acid solution that provides essential and non-essential amino acids for protein synthesis, tissue repair, and maintenance of nitrogen balance in patients unable to tolerate enteral feeding.
Procalamine is a combination of antihistamines (chlorpheniramine and pheniramine) and a sympathomimetic (phenylephrine). Chlorpheniramine and pheniramine are histamine H1 receptor antagonists, blocking the effects of histamine, while phenylephrine is an alpha-1 adrenergic receptor agonist causing vasoconstriction.
Intravenous infusion: 500 mL to 1 L of 5% solution over 8-12 hours, providing 25-50 g of amino acids. Maximum infusion rate: 0.1 g/kg/hour. Dose based on metabolic requirements and clinical status.
Intravenous: 1.5 g/kg ideal body weight (IBW) over 12-24 hours; maximal rate: 0.625 g/kg/hour.

The half-life of infused amino acids is not defined as they are endogenous compounds. However, the nitrogen from amino acids has a biological half-life of approximately 6-18 hours, depending on metabolic activity. As part of total parenteral nutrition, the elimination half-life of infused amino acids is influenced by protein turnover and catabolism.
2.5–3.5 hours in healthy adults; prolonged in renal impairment (up to 20–30 hours in ESRD).
Excretion of infused amino acids is primarily renal, with small amounts lost via feces and skin. Approximately 85-95% of the nitrogen load is excreted in urine as urea, ammonia, and other nitrogenous wastes. Less than 5% is eliminated in feces.
Primarily renal; >95% of the dose excreted unchanged in urine within 24 hours. Minimal biliary/fecal elimination (<5%).
