are saturated and unsaturated fatty acid residues. The major component fatty acids are approximately 54.5% linoleic, 22.4% oleic, 10.5% palmitic, 4.2% stearic, and 8.3% linolenic acid. These fatty acids have the following chemical and structural formulas:
Egg phosphatides, purified, are primarily a mixture of naturally occurring phospholipids which are isolated from the egg yolk. These phospholipids have the following general structure:
are the same saturated and unsaturated fatty acid residues that abound in neutral fats. R3 is primarily either the choline [HOCH2CH2N(CH3)30H] ester or ethanolamine (HOCH2CH2NH2) ester of phosphoric acid (H3PO4).
Glycerin, USP is chemically designated C3H803 and is a clear, colorless, hygroscopic syrupy liquid. It has the following structural formula:
Liposyn III (intravenous fat emulsion) is indicated as a source of calories for patients requiring parenteral nutrition. Where such nutrition is required for extended periods of time (more than 5 days), Liposyn III (intravenous fat emulsion) is also indicated as a source of essential fatty acids to prevent or reverse biochemical changes in fatty acid composition of plasma lipids (elevated triene/tetraene ratio) and the clinical manifestations of EFAD.
DOSAGE AND ADMINISTRATION
Liposyn III (intravenous fat emulsion) should be administered as part of an intravenous total nutrition program via peripheral vein or central venous catheter.
Liposyn III (intravenous fat emulsion) can provide up to 60% of daily calories at a dose not to exceed 3 g/kg of body weight per day. The other 40% should be provided by carbohydrate and amino acids.
For the prevention of essential fatty acid deficiency, the recommended daily requirement is approximately 4% of the caloric intake as linoleate. In most adult patients, this can be supplied as 500 mL of Liposyn III (intravenous fat emulsion) 10% or 250 mL of Liposyn III (intravenous fat emulsion) 20% administered three times weekly.
The initial infusion rate for the first 15 minutes should be 1.0 mL/minute for Liposyn III (intravenous fat emulsion) 10% and 0.5 mL/minute for Liposyn III (intravenous fat emulsion) 20%. If no adverse effects are observed during this initial infusion, the rate can be increased to allow no more than 500 mL of Liposyn III (intravenous fat emulsion) 10% or 250 mL of Liposyn III (intravenous fat emulsion) 20% to be given over a period of four to six hours.
Liposyn III (intravenous fat emulsion) can provide up to 60% of daily calories at a dose not to exceed 4 g/kg of body weight per day. The other 40% should be provided by carbohydrate and amino acids.
For the prevention of essential fatty acid deficiency, the recommended daily requirement is approximately 4% of the caloric intake as linoleate. The daily dosage of Liposyn III (intravenous fat emulsion) ranges from 7.5 mL to 15 mL per kilogram for the 10% emulsion and 3.8 mL to 7.5 mL per kilogram for the 20% emulsion, depending upon the size and maturity of the patient.
The infusion should be started at a rate of 0.1 mL/minute for the first 15 minutes. If no adverse effects are observed during this initial infusion, the rate can be increased to allow no more than 100 mL of Liposyn III (intravenous fat emulsion) 10% or 50 mL of Liposyn III (intravenous fat emulsion) 20% per hour.
See CONTRAINDICATIONS regarding mixing this emulsion with other I.V. fluids or additives.
Liposyn III (intravenous fat emulsion) can be infused into the same central or peripheral vein as the carbohydrate/amino acid solutions by means of a short Y-connector near the infusion site. This allows for mixing of the solutions immediately before entering the vein or for alternation of each solution. Flow rates of each solution should be controlled separately by infusion pumps, if these are used. Fat emulsion may also be infused through a separate peripheral site. If desired, heparin may be added to Liposyn III (intravenous fat emulsion) at a concentration of 1 to 2 units per mL prior to administration. Conventional administration sets contain polyvinyl chloride (PVC) components that have DEHP (diethylhexyl phthalate) as a plasticizer. Fat-containing fluids such as Liposyn extract DEHP from this PVC component, and it may be advisable to consider infusion of Liposyn III (intravenous fat emulsion) through a non-DEHP administration set. Filters should not be used for administration of the emulsion. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.
Liposyn III (intravenous fat emulsion) 10% and 20% is a white to slightly off-white emulsion with no evidence of oiling out of the emulsion.
Liposyn III (intravenous fat emulsion) 10% (List No. 9790) is supplied in 200, 250 and 500 mL single-dose containers. Liposyn III (intravenous fat emulsion) 20% (List No. 9791) is supplied in 200, 250 and 500 mL single-dose containers.
Store at 20 to 25°C (68 to 77°F). [See USP Controlled Room Temperature.] Protect from freezing.

Sepsis due to contamination of administration equipment and thrombophlebitis due to vein irritation from concurrently administered hypertonic solutions have been encountered. These are attributable to I.V. therapy in general or to the type of infusion administered.
Adverse reactions directly related to fat emulsions are of two types: (1) immediate (acute) and (2) long term (chronic). In studies of lipid products in general, the following immediate reactions have been noted: Allergic reactions, hyperlipemia, dyspnea, cyanosis, flushing, dizziness, headache, sleepiness, nausea, vomiting, hyperthermia, sweating, chest and back pain, thrombocytopenia (rarely in neonates), hypercoagulability and transient increases in liver enzymes.
The following reactions have been noted with long-term therapy with lipid infusions in general: Hepatomegaly, jaundice due to central lobular cholestasis, splenomegaly, thrombocytopenia, leucopenia, transient increases in liver function tests, overloading syndrome and the deposition of brown pigment ("fat pigment") in the reticuloendothelial tissue of the liver. The significance of this last occurrence and its cause are unknown.
No information provided.
Deaths in preterm infants after infusion of intravenous fat emulsions have been reported in the medical literature.1,2Autopsy findings included intravascular fat accumulation in the lungs. Treatment of premature and low birth weight infants with intravenous fat emulsion must be based upon careful benefit-risk assessment. Strict adherence to the recommended total daily dose is mandatory; hourly infusion rate should be as slow as possible in each case and should not in any case exceed 1 g/kg in four hours. Premature and small for gestational age infants have poor clearance of intravenous fat emulsion and increased free fatty acid plasma levels following fat emulsion infusion; therefore, serious consideration must be given to administration of less than the maximum recommended doses in these patients in order to decrease the likelihood of intravenous fat overload. The infant's ability to eliminate infused fat from the circulation must be carefully monitored (such as triglyceride and/or plasma free fatty acid levels). The lipemia must clear between daily infusions.
Caution should be exercised in administering Liposyn III (intravenous fat emulsion) to patients with severe liver damage, pulmonary disease, anemia or blood coagulation disorders or when there is danger of fat embolism. The too rapid administration of Liposyn III (intravenous fat emulsion) can cause fluid and/or fat overloading resulting in dilution of serum electrolyte concentrations, over-hydration, congested states, pulmonary edema, impaired pulmonary diffusion capacity or metabolic acidosis.
WARNING: This product contains aluminum that may be toxic. Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum.
Research indicates that patients with impaired kidney function, including premature neonates, 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.
Because free fatty acids displace bilirubin bound to albumin, the use of lipid infusions in jaundiced or premature infants should be undertaken with caution.
During Liposyn III (intravenous fat emulsion) administration, the patient's hemogram, blood coagulation, liver function, platelet count and plasma lipid profile must be closely monitored. The lipemia must clear between daily infusions. Liposyn III (intravenous fat emulsion) should be discontinued should a significant abnormality in any one of these parameters be attributed to the infusion.
Pregnancy Category C. Animal reproduction studies have not been conducted with Liposyn III (intravenous fat emulsion) . It is also not known whether Liposyn III (intravenous fat emulsion) can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Liposyn III (intravenous fat emulsion) should be given to a pregnant woman only if clearly needed.
Liposyn III (intravenous fat emulsion) is supplied in single-dose containers. Partially used containers must be discarded and should not be stored or resterilized for later use. Do not administer the contents of any container in which the emulsion appears to be oiling out.
This product contains no more than 25 mcg/L of aluminum.

In the event of fat overload during therapy, stop the infusion of Liposyn III (intravenous fat emulsion) until visual inspection of the plasma, determination of triglyceride concentrations, or measurement of plasma light-scattering activity by nephelometry indicates the lipid has cleared. Re-evaluate the patient and institute appropriate corrective measures. See WARNINGS and PRECAUTIONS.
The administration of Liposyn III (intravenous fat emulsion) (intravenous fat emulsion) is contraindicated in patients demonstrating disturbances in normal fat metabolism such as pathologic hyperlipemia, lipoid nephrosis or acute pancreatitis if accompanied by hyperlipemia.
With the exception of heparin at 1 to 2 units/mL of fat emulsion, additives to the Liposyn III (intravenous fat emulsion) bottle are contraindicated.
Partly used containers must not be stored for later use. Filters must not be used with Liposyn III (intravenous fat emulsion) . Do not use any bottle in which there appears to be an oiling out of the emulsion.
Liposyn III (intravenous fat emulsion) (intravenous fat emulsion) provides the patient requiring parenteral nutrition with a source of calories and the essential fatty acids normally obtained from a nutritionally complete oral diet. The supplemental polyunsaturated fat prevents biochemical changes of essential fatty acid deficiency (EFAD) and prevents and reverses EFAD clinical manifestations (e.g., scaliness of skin, growth retardation, poor wound healing and sparse hair growth).
The infused fat particles are cleared from the bloodstream in a manner thought to be similar to the clearing of chylomicrons. Following infusion, there is a transient increase in plasma triglycerides. The triglycerides are hydrolyzed to free fatty acids and glycerol by the enzyme, lipoprotein lipase. The free fatty acids either enter the tissues (where they may be oxidized or resynthesized into triglycerides and stored) or circulate in the plasma, bound to albumin. In the liver, circulating free fatty acids are oxidized or converted to very low density lipoproteins that re-enter the bloodstream.
Phosphatides are the hydrophobic components of membranes and provide electrically insulated layers. They are involved in the formation of membrane structures. Choline prevents the deposition of fat in the liver.
Glycerol is metabolized to carbon dioxide and glycogen or is used in the synthesis of body fats.
