AMINOSYN-RF 5.2% vs PROCALAMINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aminosyn-RF 5.2% is an amino acid solution that provides essential and nonessential amino acids for protein synthesis, primarily in patients with renal impairment. It is designed to reduce ureagenesis and nitrogenous waste accumulation by supplying a higher proportion of essential amino acids while limiting total nitrogen load.
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.
1-1.5 g/kg/day intravenously as a continuous infusion, typically 500 mL to 1000 mL/day depending on amino acid requirements and fluid status. Dose is expressed as grams of amino acids per kg of ideal body weight per day.
Intravenous: 1.5 g/kg ideal body weight (IBW) over 12-24 hours; maximal rate: 0.625 g/kg/hour.

The terminal elimination half-life of infused amino acids is approximately 10–20 minutes, reflecting rapid distribution and metabolism; clinical context: continuous infusion maintains steady state within 30 minutes.
2.5–3.5 hours in healthy adults; prolonged in renal impairment (up to 20–30 hours in ESRD).
Primarily renal; >95% of infused essential amino acids and small peptides are reabsorbed; excess amino acids are deaminated and nitrogen excreted as urea in urine (renal clearance of urea). Biliary/fecal excretion is negligible (<2%).
Primarily renal; >95% of the dose excreted unchanged in urine within 24 hours. Minimal biliary/fecal elimination (<5%).
