Upper Chamber: Aminosyn II 7%, an amino acid injection, 500 mL. Aminosyn II 7% is a sterile, nonpyrogenic solution for intravenous infusion. Lower Chamber: 50% Dextrose Injection, USP, 500 mL. 50% Dextrose Injection, USP (concentrated dextrose in water) is a sterile, nonpyrogenic, hypertonic solution of Dextrose, USP in water for injection.
Aminosyn II 3.5% in 25% Dextrose Injection is indicated for central vein infusion in the prevention of nitrogen loss and negative nitrogen balance in cases where (a) the gastrointestinal tract by the oral, gastrostomy or jejunostomy route cannot or should not be used, (b) gastrointestinal absorption of nutrients is impaired or (c) metabolic requirements for protein and calories are substantially increased as with extensive burns and (d) morbidity and mortality may be reduced by replacing amino acids lost from tissue breakdown, thereby preserving tissue reserves, as in acute renal failure. In such patients intravenous feeding for more than a few days would be expected.
The addition of supplemental electrolytes, will be required in accordance with the prescription of the attending physician.
Published Studies Related to Aminosyn II Injection (Amino Acid Injection)
Results of a phase I study in patients suffering from secondary-progressive multiple sclerosis demonstrating the safety of the amino acid copolymer PI-2301 and a possible induction of an anti-inflammatory cytokine response. [2010.08.25]
PI-2301 is an immunomodulator that could be an alternative therapy for MS. A placebo-controlled, multiple-ascending dose, double-blind study was performed in patients with secondary-progressive MS... MRI data indicated a non-significant trend for a reduction of lesion numbers in subjects treated with 1 and 3 mg PI-2301.

Effects of dimethylaminoethanol pyroglutamate (DMAE p-Glu) against memory deficits induced by scopolamine: evidence from preclinical and clinical studies. [2009.12]
RATIONALE: Dimethylaminoethanol pyroglutamate (DMAE p-Glu) is a compound resulting from the reaction between dimethylaminoethanol (an indirect precursor of acetylcholine) and pyroglutamic acid (a cyclic derivative of glutamic acid having procholinergic properties and promnesic effects in both animals and man). OBJECTIVES: The present study undertook preclinical and clinical evaluations to test a potential therapeutic utility for DMAE p-Glu in cognitive impairments related to central cholinergic deficit... CONCLUSION: These results indicate that DMAE p-Glu reduces the deleterious effect of scopolamine on long-term memory in healthy volunteers and suggest that DMAE p-Glu might be effective in reducing memory deficits in patients with cognitive impairment.
Clinical Trials Related to Aminosyn II Injection (Amino Acid Injection)
Local Effects of Amino Acids, Leucine and 3-hydroxybutyrate in the Bilaterally Perfused Human Leg [Recruiting]
Introduction: Protein loss during critical illness is an important problem and is shown to
predict overall survival. In animal studies, infusion of leucine is shown to increase the
synthesis of muscle protein by 30-40% and decrease protein degradation by 30%. Animal
studies also show that after administrating 3-hydroxybutyrate (3-OHB), cardiac output
increase, and O2 consumption decrease. Humane studies show 10% increase in protein synthesis
and 30% decrease in protein degradation after administration of 3-OHB.
Objectives: Compared to saline, an amino acid infusion in the femoral artery will promote
protein synthesis and inhibit breakdown assessed with local a/v phenylalanine and tyrosine
tracer kinetics in healthy volunteers. These effects will be further amplified by leucine
and 3-OHB enrichment and will include distinct alterations in muscle signal events, in
Methods: n = 4 x 8 healthy male subjects are equipped with catheters in aa. femorales and
vv. femorales bilaterally under local anaesthetics. Each study comprises a 3-hour basal
period and a 3-hour period with hyperinsulinaemic-euglucaemic clamp. During the test,
samples of arterial and venous blood and 4 muscle biopsies are obtained. The 4 different
studies contain continues saline infusion compared to either (i) amino acids (Vamin), (ii)
Vamin + leucine, (iii) Vamin + 3-OHB or (iiii) Vamin + leucine + 3-OHB.
Perspectives: This study elucidates whether infusion of aminoacids, leucin and
3-hydroxybutyrate can diminish protein loss and thereby potentially improve the nutrition of
all critically ill patients.
Gut Hormones After Oral Versus Intravenous Amino Acids [Recruiting]
The study hypothesis is that gut hormones are released after oral but not intravenous amino
acids which result in stimulation of insulin secretion.
Total Parenteral Nutrition Associated Cholestasis (TPNAC) and Plasma Amino Acid Levels in Neonates [Not yet recruiting]
The purpose of this study is to analyze if the infants who received Primene solution, have
lower serum levels of methionine and cysteine and higher serum levels of taurine, we also
analyze if the infants who received Primene solution develop TPN-associated cholestasis in a
smaller proportion than those who received Trophamine solution.
Leucine-enriched Essential Amino Acid Intake to Optimize Protein Anabolism in Children With Cystic Fibrosis [Recruiting]
Malnutrition, including muscle wasting commonly occurs in children with cystic fibrosis
(CF), negatively influencing their quality of life and survival. At the time of a diagnosis
of CF, severe protein deficits can already be present. It is important to get CF children
fed adequately to prevent that their condition becomes worse or that recovery takes longer.
Oral supplementation trials showed that gains in lean body mass are difficult to achieve in
CF unless specific metabolic abnormalities are targeted. However, the specific needs for
certain food components are not clear yet in children that are ill. Therefore, more
information is necessary on the need for protein and certain amino acids in children with
CF. Previous studies support the concept of essential amino acids (EAA) as an anabolic
stimulus in the young and elderly and in insulin resistant states. Until yet no information
is present on the anabolic effects of EAA in CF.
It is therefore our hypothesis that a high-leucine essential amino acids mixture
specifically designed to stimulate protein anabolism will target the metabolic alterations
of pediatric subjects with CF. In the present proposal, the acute metabolic effects of this
high leucine essential amino acids mixture will be examined in pediatric subjects with CF
and compared to that of a regular balanced total mixture of essential and non-essential
amino acids. The principal endpoints will be the extent of stimulation of whole body protein
synthesis as this is the principal mechanism by which either amino acid or protein intake
causes muscle anabolism, and the reduction in endogenous protein breakdown. Both endpoints
will be assessed by isotope methodology which is thought to be the reference method.
Modulation of Systemic Inflammatory Response in Critically Ill Children After Glutamine Supplementation [Recruiting]
This study aims to describe the use of glutamine supplementation in the modulation of
inflammatory response in critically ill pediatric patients and to determine if this decrease
leads to clinical improvement in morbidity and mortality in these patients. Thus, these
patients' diet could be supplemented with glutamine in order to improve their evolution.
From the data obtained in the study of the literature the investigators consider that:
Critically ill patients have a deficit of glutamine either because of an increase in its
consumption or a decrease in its availability, and therefore blood glutamine levels are low.
Critically ill patients have elevated blood levels of pro-inflammatory substances (IL-6).
In these patients tissue lesion inhibitors (HSP-70) in the blood are decreased. The
administration of glutamine supplements to these patients decreases oxidative stress due to
the increase in HSP-70.
Inflammation inhibitory substances (IL-10) in the blood are decreased in these patients.
The administration of glutamine supplements in these patients increase IL-10 levels.
Glutamine supplements decrease the inflammatory response with a decrease in IL-6 levels.
