Egg phospholipids are primarily a mixture of naturally occurring phospholipids which are isolated from the egg yolk. Egg phospholipids are available as an intravenous fat emulsion indicated as a source of calories for patients requiring parenteral nutrition.

Glycerin is a hyperosmotic laxative, given rectally, which usually produces a bowel movement within 15 minutes to 1 hour. Hyperosmotic laxatives encourage bowel movements by drawing water into the bowel from surrounding tissues. This produces a softer stool mass and increased bowel action. These products are used for fast, predictable relief of occasional constipation.

Glycerin is commonly classified as an osmotic laxative but may act additionally or alternatively through its local irritant effects; it may also have lubricating and fecal softening actions. Glycerin suppositories usually work within 15 to 30 minutes.

Derived from soybeans, soybean oil is a common vegetable oil and a source of polyunsaturated and saturated fatty acids. It is a complex mixture of triglycerides where per 100 g, soybean oil has 16 g of saturated fat, 23 g of monounsaturated fat, and 58 g of polyunsaturated fat. The major component fatty acids are linoleic (48% - 58%), oleic (17% - 30%), palmitic (9% -13%), linolenic (4% - 11%), and stearic (2.5% - 5.0%). It is used as a cooking oil and lipid emulsion for parenteral nutrition in clinical settings. Soybean oil-based lipid emulsion is the only FDA-approved lipid formulation for clinical use.

Soybean oil is a nutrition source that provides a biologically utilizable source of calories and essential fatty acids. It prevents the biochemical lesions of essential fatty acid deficiency (EFAD), and correct the clinical manifestations of the EFAD syndrome by supplying energy and nutrients.

Uses

Egg phospholipids is a compound used as a calorie source in parenteral nutrition.

For use as a source of calories for patients requiring parenteral nutrition.

For the relief of occasional constipation

Soybean oil is an oil used as a source of calories and essential fatty acids in selected patients for total parenteral nutrition (TPN) therapy and prevention of essential fatty acid deficiency.

Indicated for parenteral nutrition as a source of calories and essential fatty acids when oral or enteral nutrition is not possible, insufficient, or contraindicated.

How Liposyn III works

When administered rectally, glycerin exerts a hygroscopic and/or local irritant action, drawing water from the tissues into the feces and reflexively stimulating evacuation. Glycerin decreases intraocular pressure by creating an osmotic gradient between the blood and intraocular fluid, causing fluid to move out of the aqueous and vitreous humors into the bloodstream.

Fatty acids serve as an important substrate for energy production. The most common mechanism of action for energy production derived from fatty acid metabolism is beta oxidation. Fatty acids are also important for membrane structure and function, precursors for bioactive molecules (such as prostaglandins), and as regulators of gene expression. Soybean oil-based lipid emulsion may also cause an increase in heat production, decrease in respiratory quotient, and increase in oxygen consumption following its administration . Soybean oil contents prevent abnormally high triacylglycerol synthesis and its accumulation as lipid droplets in the liver by regulating hepatic lipogenesis and lipolysis. In vitro, soybean oil is shown to prevent downregulation of CYP2C2, CYP2C11 and CYP3A2 mRNA thus maintaining hepatic drug oxidation capabilities. Soybean oil is broken down into free fatty acids that activate PPAR-alpha, which regulate hepatic CYP4A1 that hydroxylate saturated and unsaturated fatty acids. Soybean oil is also shown to prevent up/downregulation of efflux transporters and maintain mRNA levels of hepatic antioxidant enzymes in vitro rat studies .

Dosage

Liposyn III dosage

Children under 2 years: Consult a physician.

Children (2 to 6 years): only 1 Glycerin 1.15 suppository per 24 hours or as directed by a physician.

Adults and Children (From 6 years): only 1 Glycerin 2.30 suppository per 24 hours or as directed by a physician

Insert suppository well up into rectum. Suppository need to melt completely to produce laxative action.

Side Effects

Glycerin when used rectally may cause rectal discomfort or a burning sensation

Toxicity

Glycerol has very low toxicity when ingested ; Rat LD50 (oral)-12600mg/kg Mice LD50 (oral )-4090mg/kg Human TDLo (oral) - 1428mg/kg

The most frequent adverse effects were nausea, vomiting and muscle spasm. Soybean oil-based lipid emulsions can cause hypersensitivity reactions and risks of catheter-related infections. Fat overload syndrome is a rare condition that has been reported with intravenous lipid emulsions, due to a reduced or limited ability to metabolize lipids accompanied by prolonged plasma clearance. Worsensing conditions of the patients can be seen including hematological effects, declined hepatic function and central nervous system manifestations. Hypertriglyceridema may occur. Preterm and small-for-gestational-age infants have poor clearance of intravenous lipid emulsion and increased free fatty acid plasma levels following lipid emulsion infusion, leading to accumulation in lungs. It is advised not to exceed 0.75 mL/kg/hour.

Volume of Distribution

Glycerin is distributed throughout the blood. Although glycerin generally does not appear in ocular fluids, it may enter the orbital sac when the eye is inflamed, with a consequent decrease in osmotic effect.

After triglycerides are hydrolyzed, fatty acids can enter the tissues where they may be oxidized or resynthesized into triglcerides and stored.

Elimination Route

Well absorbed orally, poorly absorbed rectally. Studies in humans and animals indicate glycerol is rapidly absorbed in the intestine and the stomach

Following infusion, there is a transient increase in plasma triglycerides.

Half Life

30 - 45 minutes

Clearance

The elimination rate of lipid emulsions depends on particle size, fatty acid composition, apolipoprotein content of the lipid globules, lipoprotein lipase activity, and hepatic lipase activity .
