Drug Class: Amino Acid

Overview

DESCRIPTION Aminosyn ® -PF 7%, Sulfite-Free, (an amino acid injection — pediatric formula) is a sterile, nonpyrogenic solution for intravenous infusion. Aminosyn ® -PF 7% is oxygen sensitive. The formulation is described below: Aminosyn-PF 7% An Amino Acid Injection — Pediatric Formula Essential Amino Acids (mg/100 mL) Isoleucine 534 Leucine 831 Lysine (acetate)* 475 Methionine 125 Phenylalanine...

Mechanism of Action

CLINICAL PHARMACOLOGY Aminosyn-PF 7% Sulfite-Free, (an amino acid injection — pediatric formula) contains a mixture of essential and nonessential amino acids as well as taurine. The amino acid composition has been specifically formulated to provide a well-tolerated nitrogen source for nutritional support and therapy for infants and young children. When administered in conjunction with a cysteine hydrochloride additive, Aminosyn-PF 7% results in plasma amino acid concentrations approximating a profile consistent with that of a breast-fed infant. The rationale for Aminosyn-PF 7% is based on the observation of inadequate levels of essential amino acids in the plasma of infants receiving total parenteral nutrition (TPN) using conventional amino acid solutions.

Indications

  • INDICATIONS AND USAGE Aminosyn-PF 7%, Sulfite-Free, (an amino acid injection — pediatric formula) is indicated for the nutritional support of infants (including those of low birth weight) and young children requiring TPN via either central or peripheral infusion routes. Parenteral nutrition with Aminosyn-PF 7% is indicated to prevent nitrogen and weight loss or treat negative nitrogen balance in infants and young children where (1) the alimentary tract by the oral gastrostomy, or jejunostomy route, cannot or should not be used or adequate protein intake is not feasible by these routes, (2)...

Common Doses

  • 2.5 g
  • 25 g
  • 1.25 g
  • 1 g

Dosage

DOSAGE AND ADMINISTRATION The total daily dose of the solution depends on the daily protein requirements and on the patient's metabolic and clinical response. Pediatric requirements for parenteral nutrition are constrained by the greater relative fluid requirements of the infant and greater caloric requirements per kilogram than in the adult. The recommended intravenous dose of Aminosyn-PF 7%, Sulfite-Free, (an amino acid injection — pediatric formula) is up to 2.5 g amino acid/kg/day for infants up to 10 kg.

Contraindications

  • CONTRAINDICATIONS Aminosyn-PF 7%, Sulfite-Free, (an amino acid injection — pediatric formula) is contraindicated in patients with untreated anuria, hepatic coma, inborn errors of amino acid metabolism (including those involving branched chain amino acid metabolism such as maple syrup urine disease and isovaleric acidemia), or hypersensitivity to one or more amino acids present in the solution.

Side Effects

  • ADVERSE REACTIONS Local reactions consisting of erythema, phlebitis and thrombosis at the infusion site have occurred with peripheral intravenous infusion of amino acids particularly if other substances, such as antibiotics, are also administered through the same site. In such cases the infusion site should be changed promptly to another vein. Use of large peripheral veins, inline filters, and slowing the rate of infusion may reduce the incidence of local venous irritation. Electrolyte additives should be spread throughout the day.

Interactions

  • No major interactions listed on the FDA label. Always consult a healthcare professional.
