DOSAGE AND ADMINISTRATION

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 PN 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 redissolve upon dilution during admixture compounding.
Evaluate the following:
- If the outlet port protector is damaged, detached, or not present, discard container as solution path sterility may be impaired.
- Check to ensure the solution is clear, colorless or slightly yellow. Discard if the solution is bright yellow or yellowish brown.
- 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 PN 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].
Use a dedicated line for PN 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].
Prior to infusion, visually inspect the diluted PN 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.

Preparation Instructions For Admixing Using A Parenteral Nutrition (PN) 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 PN container using strict aseptic techniques to avoid microbial contamination.
Do not add the lipid emulsion to the PN 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 PN container.
2. Transfer PROSOL to the PN container.
3. Transfer lipid emulsion to the PN container.
Because additives may be incompatible, evaluate all additions to the PN 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 PN 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 PN container of PROSOL, dextrose injection and lipid emulsion is also permitted.
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 PN solution containing PROSOL to ensure that:
- Precipitates have not formed during the mixing or addition of additives.
- 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.
- Discard the admixture if any of the above are observed.
For single use only. Discard used container of PROSOL.
Use for admixing should be limited to up to 4 hours at room temperature (25°C/77°F) 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.
Do not connect flexible containers in series to avoid air embolism due to possible residual gas contained in the primary container.
Air embolism can result if residual gas in the container is not fully evacuated prior to administration if the flexible container is pressurized to increase flow rates.
If administration is controlled by a pumping device, discontinue pumping action before the container runs dry to avoid air embolism.
For automated compounding, refer to Instructions for Use of the applicable compounder.
Containers should not be written on directly since ink migration has not been investigated. Affix accompanying label for date and time of entry.

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 PN 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 PN solution containing PROSOL must be based on the concentrations of all components in the solution and the recommended nutritional requirements [see Recommended Dosage In Adults, Dosage Modifications In Patients With Renal Impairment, Recommended Dosage In Pediatric Patients]. 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 PN 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 PN. See complete prescribing information of lipid emulsion.
Prior to administration of PN 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 PN therapy. It may be necessary to add additional potassium to the PN admixture.

Recommended Dosage In Adults

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

As a component of PN, 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 PN solution to meet nutrient needs and prevent deficiencies and complications from developing.

A maximum fluid supply of 40 mL/kg/day of PN 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 PN 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.

Table 1. Recommended Daily Dosage in Adults

Adult Patient Population	Recommended Protein^a Requirement (g/kg/day)¹	Corresponding Nitrogen Requirement (g/kg/day)	Recommended Daily Dosage of PROSOL (mL/kg/day)^b
Stable Patients	0.8 to 1.0	0.13 to 0.16	4 to 5
Critically Ill Patients^c	1.5 to 2.0	0.24 to 0.32	7.5 to 10
^a Protein is provided as amino acids. When infused intravenously, amino acids are metabolized and utilized as the building blocks of protein. ^b A maximum fluid supply of 40 mL/kg/day of parenteral nutrition solution should not be exceeded in adult patients. ^c Includes patients requiring more than 2 to 3 days in the intensive care unit with organ failure, sepsis or postoperative major surgery. Do not use in patients with conditions that are contraindicated [see CONTRAINDICATIONS].

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].

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]. 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 PN admixtures if used in this pediatric population.

Table 2. Recommended Daily Dosage in Pediatrics

Age	Recommended Protein^a Requirement (g/kg/day)¹	Corresponding Nitrogen Requirement (g/kg/day)	Recommended Daily Dosage of PROSOL (mL/kg/day)
Preterm and term infants less than 1 month of age	3 to 4	0.48 to 0.64	15 to 20
Pediatric patients > 1 month to 1 year of age	2 to 3	0.32 to 0.48	10 to 15
Pediatric patients 1 to 10 years of age	1 to 2	0.16 to 0.32	5 to 10
Pediatric patients 11 to 17 years of age	0.8 to 1.5	0.13 to 0.24	4 to 7.5
^a Protein is provided as amino acids. When infused intravenously, amino acids are metabolized and utilized as the building blocks of protein.

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 PN solutions containing dextrose.

Warnings & Precautions

WARNINGS

Included as part of the "PRECAUTIONS" Section

PRECAUTIONS

Pulmonary Embolism Due To Pulmonary Vascular Precipitates

Pulmonary vascular precipitates causing pulmonary vascular emboli and pulmonary distress have been reported in patients receiving PN. In some cases, fatal outcomes due to pulmonary embolism have occurred. PROSOL contains no added phosphorus. Patients, especially those with hypophosphatemia, may require the addition of phosphate. To prevent hypocalcemia, calcium supplementation should always accompany phosphate administration. Excessive addition of calcium and phosphate increases the risk of the formation of calcium phosphate precipitates. Precipitates have been reported even in the absence of phosphate salt in the solution. Precipitation following passage through an in-line filter and suspected in vivo precipitate formation has also been reported. If signs of pulmonary distress occur, stop the infusion and initiate a medical evaluation. In addition to inspection of the solution [see DOSAGE AND ADMINISTRATION], the infusion set and catheter should also periodically be checked for precipitates.

Hypersensitivity Reactions

Hypersensitivity reactions including anaphylaxis have been reported with PN solutions containing PROSOL. Stop the infusion immediately and treat patient accordingly if any signs or symptoms of a hypersensitivity reaction develop. Signs or symptoms may include: hypotension, hypertension, peripheral cyanosis, tachycardia, dyspnea, vomiting, nausea, urticaria, rash, pruritus, erythema, hyperhidrosis, pyrexia, and chills.

Risk Of Infections

Patients who require PN are at high risk of infections because the nutritional components of these solutions can support microbial growth. Infection and sepsis may also occur as a result of the use of intravenous catheters to administer PN.

The risk of infection is increased in patients with malnutrition-associated immunosuppression, hyperglycemia exacerbated by dextrose infusion, long-term use and poor maintenance of intravenous catheters, or immunosuppressive effects of other concomitant conditions, drugs, or other components of the parenteral formulation (e.g., lipid emulsion).

To decrease the risk of infection, ensure aseptic technique in catheter placement and maintenance, as well as aseptic technique in the preparation and administration of the nutritional formula.

Monitor for signs and symptoms (including fever and chills) of early infections, including laboratory test results (including leukocytosis and hyperglycemia) and frequent checks of the parenteral access device and insertion site for edema, redness and discharge.

Refeeding Syndrome

Refeeding severely undernourished patients may result in refeeding syndrome, characterized by the intracellular shift of potassium, phosphorus, and magnesium as the patient becomes anabolic. Thiamine deficiency and fluid retention may also develop. To prevent these complications, monitor severely undernourished patients and slowly increase nutrient intakes.

Hyperglycemia Or Hyperosmolar Hyperglycemic State

Administration of PN solutions containing dextrose in patients with diabetes mellitus, impaired glucose tolerance may worsen hyperglycemia. Administration of dextrose at a rate exceeding the patient’s utilization rate may lead to hyperglycemia, coma, and death. Patients with underlying confusion and renal impairment who receive dextrose infusions, may be at greater risk of developing hyperosmolar hyperglycemic state. Monitor blood glucose levels and treat hyperglycemia to maintain optimum levels while administering PN solutions containing dextrose. Insulin may be administered or adjusted to maintain optimal blood glucose levels during administration of PN solutions containing dextrose.

Vein Damage And Thrombosis

PROSOL must be diluted and used as an admixture with or without dextrose, electrolytes and/or lipid emulsion. It is not for direct intravenous infusion. Solutions containing more than 5% dextrose or with an osmolarity of 900 mOsm/L or greater must be infused through a central catheter [see DOSAGE AND ADMINISTRATION]. The infusion of hypertonic nutrient injections into a peripheral vein may result in vein irritation, vein damage, and/or thrombosis. The primary complication of peripheral access is venous thrombophlebitis, which manifests as pain, erythema, tenderness or a palpable cord. Remove the catheter as soon as possible, if thrombophlebitis develops.

Hepatobiliary Disorders

Hepatobiliary disorders are known to develop in some patients without preexisting liver disease who receive PN, including cholecystitis, cholelithiasis, cholestasis, hepatic steatosis, fibrosis and cirrhosis, possibly leading to hepatic failure. The etiology of these disorders is thought to be multifactorial and may differ between patients.

Increase in blood ammonia levels and hyperammonemia may occur in patients receiving amino acid solutions, including PROSOL. In some patients, this may indicate hepatic insufficiency or the presence of an inborn error of amino acid metabolism [see CONTRAINDICATIONS, Use In Specific Populations].

Monitor liver function parameters and ammonia levels. Patients developing signs of hepatobiliary disorders should be assessed early by a clinician knowledgeable in liver diseases in order to identify possible causative and contributory factors, and possible therapeutic and prophylactic interventions.

Aluminum Toxicity

PROSOL contains no more than 25 mcg/L of aluminum. However, with prolonged parenteral administration in patients with renal impairment, the aluminum contained in PROSOL may reach toxic levels. Preterm infants are at a greater risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum.

Patients with renal impairment, including preterm infants, who receive parenteral levels of aluminum at greater than 4 to 5 mcg/kg/day, accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates of administration.

Risk Of Parenteral Nutrition Associated Liver Disease

Parenteral Nutrition Associated Liver Disease (PNALD) has been reported in patients who receive PN for extended periods of time, especially preterm infants, and can present as cholestasis or steatohepatitis. The exact etiology is unknown and is likely multifactorial. If patients treated with PN solutions containing PROSOL develop liver test abnormalities, consider discontinuation or dosage reduction.

Electrolyte Imbalance And Fluid Overload

Patients with renal impairment, such as pre-renal azotemia, renal obstruction, and protein-losing nephropathy may be at increased risk of electrolyte and fluid volume imbalance. Patients with cardiac insufficiency and pulmonary congestion are susceptible to excess fluid accumulation. Use PN solutions containing PROSOL with caution in patients with cardiac insufficiency or renal impairment. The dosage of PN may require adjustment with specific attention to fluid, protein, and electrolyte content in these patients.

Monitor renal function parameters. Patients developing signs of renal impairment should be assessed early by a clinician knowledgeable in renal disease in order to determine the appropriate PN dosage and other treatment options.

Monitoring/Laboratory Tests

Monitor fluid and electrolyte status, serum osmolarity, blood glucose, liver and kidney function, blood count and coagulation par5.ameters throughout treatment. If electrolyte levels are severely elevated, stop PN containing PROSOL until levels have been corrected.

Overdosage & Contraindications

OVERDOSE

An increased infusion rate of PN can cause hypervolemia, electrolyte disturbances, acidosis and/or azotemia, hyperglycemia, hyperosmolality [see WARNINGS AND PRECAUTIONS].

Severe hyperglycemia and severe dilutional hyponatremia, and their complications, can be fatal.

Discontinue infusion and institute appropriate corrective measures in the event of overhydration or solute overload during therapy, with particular attention to respiratory and cardiovascular systems.

For current information on the management of poisoning or overdosage, contact the National Poison Control Center at 1-800-222-1222 or www.poison.org.

CONTRAINDICATIONS

The use of PROSOL is contraindicated in:

Patients with known hypersensitivity to one or more amino acids [see WARNINGS AND PRECAUTIONS].
Patients with inborn errors of amino acid metabolism due to risk of severe metabolic or neurologic complications.
Patients with pulmonary edema or acidosis due to low cardiac output.

Clinical Pharmacology

CLINICAL PHARMACOLOGY

Mechanism Of Action
