Description
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.
Indication
Indicated for parenteral nutrition as a source of calories and essential fatty acids when oral or enteral nutrition is not possible, insufficient, or contraindicated.
Mechanism of Action
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 [L855]. 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 [A19591].
Pharmacokinetics
- Absorption
- Following infusion, there is a transient increase in plasma triglycerides.
- Distribution
- After triglycerides are hydrolyzed, fatty acids can enter the tissues where they may be oxidized or resynthesized into triglcerides and stored.
- Metabolism
- The infused lipid particles are removed from the bloodstream in a manner generally thought to be similar to the enzymatic clearance of naturally produced chylomicrons formed after enteral fat intake. The triglycerides are hydrolyzed to free fatty acids and glycerol by the enzyme lipoprotein lipase. In the liver, circulating free fatty acids are oxidized or converted to very low density lipoproteins by hepatic lipase that re-enter the bloodstream.
- Elimination
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 [L854].
Toxicity
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.
