ProSol Dosage

Important Preparation Information

PROSOL is supplied as a pharmacy bulk package for admixing only and is not for direct intravenous infusion. Prior to administration, PROSOL must be transferred to a separate parenteral nutrition container, diluted and used as an admixture with or without dextrose, electrolytes and/or lipid emulsion.

•

The key factor in preparation is careful aseptic technique to avoid inadvertent touch contamination during mixing of solutions and addition of other nutrients.

•

Do not remove container from overpouch until ready to use.

•

Tear protective overpouch across top at slit and remove solution container. Small amounts of moisture may be found on the solution container from water permeating from inside the container. The amount of permeated water is insufficient to affect the solution significantly. If larger amounts of water are found, the container should be checked for tears or leaks.

•

Inspect PROSOL prior to use. 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. Amino acid crystals may be present. Crystals will re-dissolve upon dilution during admixture compounding.

Evaluate the following:

o

If the outlet port protector is damaged, detached, or not present, discard container as solution path sterility may be impaired.

o

Check to ensure the solution is clear, colorless or slightly yellow. Discard if the solution is bright yellow or yellowish brown.

o

Check for minute leaks by squeezing inner container. If leaks are found, discard container.

•

PROSOL is intended for use in the preparation of sterile, intravenous admixtures. Because additives may be incompatible with PROSOL, evaluate all additions for compatibility.

Administration Instructions

PROSOL is for admixing use only. It is not for direct intravenous infusion. Prior to administration, PROSOL must be diluted with other compatible intravenous fluids or used as an admixture with or without dextrose, electrolytes and/or lipid emulsion.

•

PROSOL is to be used only in a suitable work area such as a laminar flow hood (or an equivalent clean air compounding area). The key factor in the preparation is careful aseptic technique to avoid inadvertent touch contamination during mixing of solutions and addition of other nutrients.

•

PROSOL is for admixing with dextrose injection and/or lipid emulsions using a parenteral nutrition container.

•

When PROSOL is admixed with dextrose injection and/or lipid emulsion, the choice of a central or peripheral venous route should depend on the osmolarity of the final infusate. Solutions with greater than 5% dextrose or with osmolarity of 900 mOsm/L or greater must be infused through a central venous catheter [see Warnings and Precautions (5.6)].

•

Use a dedicated line for parenteral nutrition solutions.

•

Intravenous lipid emulsions can be infused concurrently into the same vein as PROSOL -dextrose solutions by a Y-connector located near the infusion site; flow rates of each solution should be controlled separately by infusion pumps.

•

For administration without lipid emulsion, use a 0.22 micron in-line filter. If lipid emulsion is also administered, use a 1.2 micron in-line filter.

•

To prevent air embolism, use a non-vented infusion set or close the vent on a vented set, avoid multiple connections, do not connect flexible containers in series, fully evacuate residual gas in the container prior to administration, do not pressurize the flexible container to increase flow rates, and if administration is controlled by a pumping device, turn off pump before the container runs dry.

•

If admixed or infused with lipid emulsion, do not use administration sets and lines that contain di-2-ethylhexyl phthalate (DEHP). Administration sets that contain polyvinyl chloride (PVC) components have DEHP as a plasticizer.

•

Calcium and phosphate ratios must be considered. Excess addition of calcium and phosphate, especially in the form of mineral salts, may result in the formation of calcium phosphate precipitates [see Warnings and Precautions (5.1)].

•

Prior to infusion, visually inspect the diluted parenteral nutrition solution containing PROSOL for particulate matter. The solution should be clear and there should be no precipitates. A slight yellow color does not alter the quality and efficacy of this product. If lipid has been added, ensure the emulsion has not separated. Separation of the emulsion can be visibly identified by a yellowish streaking or the accumulation of yellowish droplets in the mixed emulsion. Discard the admixture if any of the above are observed.

​2.3 Preparation Instructions for Admixing Using a Parenteral Nutrition Container

•

Open by tearing protective overwrap across top at slit and remove solution container. If overpouch has been previously opened or is damaged, discard solution.

•

If the outlet port protector is damaged, detached, or not present, discard the container.

•

Some opacity of the plastic due to moisture absorption during the sterilization process may be observed.

•

Check for minute leaks by squeezing the inner container firmly. If leaks are found, discard solution.

•

Once the protective foil overwrap has been removed, 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.

•

Prepare the admixture into the parenteral nutrition container using strict aseptic techniques to avoid microbial contamination.

•

Do not add the lipid emulsion to the parenteral nutritional container first; destabilization of the lipid emulsion may occur from such an admixture.

•

PROSOL may be mixed with dextrose injection and/or lipid emulsion. The following proper mixing sequence must be followed to minimize pH related problems by ensuring that typically acidic dextrose injections are not mixed with lipid emulsions alone:

1.

Transfer dextrose injection to the parental nutrition container.

2.

Transfer PROSOL to the parenteral nutrition container.

3.

Transfer lipid emulsion to the parenteral nutrition container.

•

Because additives may be incompatible, evaluate all additions to the parenteral nutrition container for compatibility and stability of the resulting preparation. Consult with pharmacist, if available. Questions about compatibility may be directed to Baxter. If it is deemed advisable to introduce additives to the parenteral nutrition container, use aseptic technique.

•

Use gentle agitation during admixing to minimize localized concentration effects; shake containers gently after each addition.

•

Alternatively, simultaneous transfer to the parenteral nutrition container of PROSOL, dextrose injection and lipid emulsion is also permitted.

•

For admixing using an automated device, refer to Instructions for Use for the applicable device.

•

The prime destabilizers of emulsions are excessive acidity (such as pH below 5) and inappropriate electrolyte content. Give careful consideration to additions of divalent cations (Ca++ and Mg++), which have been shown to cause emulsion instability. Amino acid solutions exert buffering effects that protect the emulsion.

•

Inspect the final parenteral nutrition solution containing PROSOL to ensure that:

o

Precipitates have not formed during the mixing or addition of additives.

o

The emulsion has not separated. Separation of the emulsion can be visibly identified by a yellowish streaking or the accumulation of yellowish droplets in the admixed emulsion.

o

Discard the admixture if any of the above are observed.

•

Containers should not be written on directly since ink migration has not been investigated. Affix accompanying label for date and time of entry.

Stability and Storage

•

Use for admixing should be limited to up to 4 hours at room temperature (25ºC/77ºF) after the container closure has been penetrated.

•

Admixtures should be used promptly with storage under refrigeration 2° to 8°C (36° to 46°F) not to exceed 24 hours and must be completely used within 24 hours after removal from refrigeration. Any mixture remaining must be discarded.

•

​Protect the admixed parenteral nutrition solution from light.

•

For single use only. Discard used container of PROSOL.

Dosing Considerations

•

PROSOL is for admixing only. It is not for direct intravenous infusion. Prior to administration, PROSOL must be diluted with other compatible intravenous fluids or used as an admixture with or without dextrose, electrolytes and lipid emulsion.

•

PROSOL is a part of the parenteral nutrition regimen which also includes dextrose, electrolytes, and lipid emulsion. Protein, caloric, fluid and electrolyte requirements all need to be taken into consideration when determining individual patient dosage needs.

•

The dosage of the final parenteral nutrition solution containing PROSOL must be based on the concentrations of all components in the solution and the recommended nutritional requirements [see Dosage and Administration (2.5, 2.6, 2.7)]. Consult the prescribing information of all added components to determine the recommended nutritional requirements for dextrose and lipid emulsion, as applicable.

•

The dosage of PROSOL should be individualized based on the patient’s clinical condition (ability to adequately metabolize amino acids), body weight and nutritional/fluid requirements, as well as additional energy given orally/enterally to the patient. Prior to initiating parenteral nutrition, the following patient information should be reviewed: review of all medications, gastrointestinal function and laboratory data (such as electrolytes (including magnesium, calcium, and phosphorus), glucose, urea/creatinine, liver panel, complete blood count and triglyceride level (if adding lipid emulsion)).

•

Lipid emulsion administration should be considered with prolonged use (more than 5 days) of parenteral nutrition and 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 parenteral nutrition. See complete prescribing information of lipid emulsion.

•

Prior to administration of parenteral nutrition solution containing PROSOL, correct severe fluid, electrolyte and acid-base disorders.

•

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.

•

Monitor levels of serum potassium during parenteral nutrition therapy. It may be necessary to add additional potassium to the parenteral nutrition admixture.

Recommended Dosage in Adults

The recommended adult daily dosage of PROSOL and the nutritional requirements for protein (nitrogen) are shown inTable 1.

As a component of parenteral nutrition, PROSOL provides 0.2 g protein/mL, which corresponds to 0.032 g nitrogen/mL.

As indicated on an individual basis, vitamins, electrolytes, trace elements and other components (including dextrose, electrolytes and lipid emulsion) can be added to the parenteral nutrition solution to meet nutrient needs and prevent deficiencies and complications from developing.

A maximum fluid supply of 40 mL/kg/day of parenteral nutrition solution, based on protein, should not be exceeded in adult patients; this volume does not take carbohydrates or electrolytes into consideration.

The flow rate of the parenteral nutrition solution must be adjusted taking into account the dose being administered, the daily volume intake, and the duration of the infusion. The flow rate should be increased gradually and governed, especially during the first few days of therapy, by the patient’s tolerance to dextrose. Daily intake of PROSOL and dextrose should be increased gradually to the maximum required dose as indicated by frequent determinations of blood glucose levels.

Dosage Modifications in Patients with Renal Impairment

Prior to administration, correct severe fluid or electrolyte imbalances. Closely monitor serum electrolyte levels and adjust the volume of parenteral nutrition administered as required [see Warnings and Precautions (5.10)].

Patients with renal impairment not needing dialysis require 0.6 to 0.8 g of protein/kg/day. Serum electrolyte levels should be closely monitored. Patients on hemodialysis or continuous renal replacement therapy should receive 1.2 to 1.8 g of protein/kg/day up to a maximum of 2.5 g of protein/kg/day based on nutritional status and estimated protein losses.2

Recommended Dosage in Pediatric Patients

The dosage and constant infusion rate of intravenous dextrose must be selected with caution in pediatric patients, particularly neonates and low weight infants, because of the increased risk of hyperglycemia/hypoglycemia [see Use in Specific Populations (8.4)]. Frequent monitoring of serum glucose concentrations is required when dextrose is prescribed to pediatric patients, particularly neonates and low birth weight infants. The infusion rate and volume should be determined by the consulting physician experienced in pediatric intravenous fluid therapy.

In pediatric patients, PROSOL is dosed on the basis of protein provided as amino acids. The recommended dosage, by age group is provided in Table 2.

Infusion rates are based on protein and do not take carbohydrates, fluid or electrolytes into consideration.

PROSOL does not contain the amino acids cysteine and taurine, considered conditionally essential for neonates and infants. If possible, these amino acids should be added to the parenteral nutrition admixtures if used in this pediatric population.

Discontinuation of Parenteral Nutrition

To reduce the risk of hypoglycemia after discontinuation, a gradual decrease in flow rate in the last hour of infusion should be considered when administering parenteral nutrition solutions containing dextrose.
