DOSAGE AND ADMINISTRATION
If a patient is unable to take enteral nourishment for a
prolonged period of time, institution of total parenteral nutrition (TPN) with
exogenous calories should be considered.
The total daily dose of 10% TRAVASOL (Amino Acid)
Injection depends on the patient's metabolic requirement and clinical response.
The determination of nitrogen balance and accurate daily body weights,
corrected for fluid balance, are probably the best means of assessing
individual nitrogen requirements.
Recommended Dietary Allowances* of protein range from
approximately 0.75 g/kg of body weight for adults to 1.68 g/kg for infants. It
must be recognized, however, that protein as well as caloric requirements in
traumatized or malnourished patients may be increased substantially. Daily
amino acid doses of approximately 1.0 to 1.5 g/kg of body weight for adults
with adequate calories are generally sufficient to satisfy protein needs and
promote positive nitrogen balance.
For the initial treatment of trauma or protein calorie
malnutrition, higher doses of protein with corresponding quantities of
carbohydrate will be necessary to promote adequate patient response to therapy.
The severity of the illness being treated is the primary consideration in
determining proper dose level. Such higher doses, especially in infants, must
be accompanied by more frequent laboratory evaluation.
For protein-sparing in well-nourished patients not receiving
significant additional calories, amino acid dosages of 1.0 to 1.7 g/kg/day
reduce nitrogen losses and spare body protein. If daily increases in BUN in the
range of 10 to 15 mg% for more than three days should occur, then
protein-sparing therapy should be discontinued and a regimen with full
nonprotein calorie substrates should be adopted.
Care should be exercised to insure the maintenance of
proper levels of serum potassium. Quantities of 60 to 180 mEq of potassium per
day have been used with adequate clinical effect. It may be necessary to add
quantities of this electrolyte to this injection, depending primarily on the
amount of carbohydrate administered to and metabolized by the patient.
This injection provides a concentrated credit of amino
acids to meet the protein requirements of patients that are fluid restricted
(e.g., renal failure). Acceptable total daily administration volumes are dependent
upon the fluid balance requirements of the patient. Extreme care should be
given to prevent fluctuations of blood osmolarity and serum electrolyte
concentrations. Frequent and careful monitoring is mandatory when fluid
restricted patients are receiving intravenous nutrition.
Patients receiving this injection should be monitored
(carefully) and their electrolyte requirements individualized.
Total daily fluid requirements can be met beyond the
volume of amino acid solutions by supplementing with noncarbohydrate or
carbohydrate-containing electrolyte solutions.

Maintenance vitamins, additional electrolytes and trace
elements should be administered as required.
Fat emulsion coadministration should be considered when
prolonged parenteral nutrition (more than 5 days) is required in order to
prevent essential fatty acid deficiency (EFAD). Serum lipids should be monitored
for evidence of EFAD in patients maintained on fat free total parenteral
nutrition.
Pediatric Use
Use of 10% TRAVASOL (Amino Acid) Injection in pediatric
patients is governed by the same considerations that affect the use of any
amino acid solution in pediatrics. The amount administered is dosed on the
basis of grams of amino acids/kg of body weight/day. Two to three g/kg of body
weight for infants with adequate calories are generally sufficient to satisfy
protein needs and promote positive nitrogen balance. Solutions administered by
peripheral vein should not exceed twice normal serum osmolarity (718 mOsmol/L).
Central Vein Administration
Hypertonic mixtures of amino acids and dextrose may be
administered safely by continuous infusion through a central vein catheter with
the tip located in the vena cava. In addition to meeting nitrogen needs, the
administration rate is governed, especially during the first few days of
therapy, by the patient's tolerance to dextrose. Daily intake of amino acids
and dextrose should be increased gradually to the maximum required dose as
indicated by frequent determinations of urine and blood sugar levels.
In many patients, provision of adequate calories in the
form of hypertonic dextrose may require the administration of exogenous insulin
to prevent hyperglycemia and glycosuria.
Parenteral nutrition may be started with infusates
containing lower concentrations of dextrose; dextrose content may be gradually
increased to estimated caloric needs as the patient's glucose tolerance increases.
Sudden cessation in administration of concentrated
dextrose solution may result in insulin reaction due to continued endogenous
insulin production. Such solutions should be withdrawn slowly.
Peripheral Vein Administration
For patients requiring parenteral nutrition in whom the
central vein route is not indicated, this injection can be mixed with low
concentration dextrose solutions and administered by peripheral vein in conjunction
with or without fat emulsions. In pediatric patients, the final solution should
not exceed twice normal serum osmolarity (718 mOsmol/L).
Intravenous fat emulsions provide approximately 1.1
kcal/mL (10%) or 2.0 kcal/mL (20%) and may be administered along with amino
acid-dextrose solutions by means of a short Y-connector near the infusion site
to supplement caloric intake. Fat, however, should not be the sole caloric
intake since studies have indicated that glucose is more nitrogen sparing in
the stressed patient.
Protein-Sparing
For well-nourished patients who require short-term
parenteral support, 10% TRAVASOL (Amino Acid) Injection can be administered
peripherally with or without carbohydrate calories. Such infusates can be
prepared by dilution of this injection with Sterile Water for Injection or 5%
Dextrose Injection to prepare isotonic or slightly hypertonic solutions which
may be administered by peripheral vein.
Depending upon the clinical condition of the patient,
approximately 3 liters of solution may be administered per 24 hour period. When
used postoperatively, the therapy should begin with 1000 mL on the first
postoperative day. Thereafter, the dose may be increased to 3000 mL per day. Parenteral
drug products should be inspected visually for particulate matter and
discoloration prior to administration whenever solution and container permit.
Use of a final filter is recommended during administration of all parenteral
solutions where possible.
Do not administer unless solution is clear and seal is
intact.
A slight yellow color does not alter the quality and
efficacy of the product.

compounding admixtures, use aseptic technique. Mix thoroughly. Do not store any
unused portion of 10% TRAVASOL (Amino Acid) Injection.
Any storage should be under refrigeration and limited to
a brief period of time, preferably less than 24 hours.
Directions for use of VIAFLEX plastic Pharmacy Bulk
Package container
To Open
Tear overpouch down side at slit and remove solution
container. Visually inspect the container. If the outlet port protector is
damaged, detached, or not present, discard container as solution path sterility
may be impaired. Some opacity of the plastic due to moisture absorption during
the sterilization process may be observed. This is normal and does not affect
the solution quality or safety. The opacity will diminish gradually. Check for
minute leaks by squeezing inner bag firmly. If leaks are found, discard solution
as sterility may be impaired.
For compounding only, not for direct infusion.
Preparation for Admixing
- The Pharmacy Bulk Package is to be used only in a
suitable work area such as a laminar flow hood (or an equivalent clean air
compounding area).
- Suspend container from eyelet support.
- Remove plastic protector from outlet port at bottom of
container.
- Attach solution transfer set. Refer to complete
directions accompanying set. Note: The closure shall be penetrated only one
time with a suitable sterile transfer device or dispensing set which allows measured
dispensing of the contents.
- VIAFLEX containers should not be written on directly
since ink migration has not been investigated. Affix accompanying label for
date and time of entry.
- Once container closure has been penetrated, withdrawal of
contents should be completed without delay. After initial entry, maintain
contents at room temperature (25°C/77°F) and dispense within 4 hours.
