AMINOSYN-PF 7% vs PROCALAMINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn-PF 7% is a crystalline amino acid solution that provides essential and non-essential amino acids for protein synthesis, thereby maintaining nitrogen balance and supporting tissue repair and growth in parenteral nutrition.
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; typical adult dose: 1-2 g amino acids/kg/day (e.g., 14-28 mL/kg/day for 7% solution) as part of parenteral nutrition. Infusion rate not to exceed 0.1 g amino acids/kg/hour.
Intravenous: 1.5 g/kg ideal body weight (IBW) over 12-24 hours; maximal rate: 0.625 g/kg/hour.

As a mixture of amino acids, individual amino acids have half-lives ranging from minutes to hours; clinically, continuous infusion maintains steady state.
2.5–3.5 hours in healthy adults; prolonged in renal impairment (up to 20–30 hours in ESRD).
Amino acids are primarily cleared by metabolism; less than 10% is excreted unchanged in urine.
Primarily renal; >95% of the dose excreted unchanged in urine within 24 hours. Minimal biliary/fecal elimination (<5%).
