Intralipid is a fat emulsion used intravenously as a source of calories and essential fatty acids for patients who are unable to obtain adequate nutrition through oral intake. It is commonly used in hospitals and healthcare facilities for patients requiring parenteral nutrition, such as those with gastrointestinal disorders that impair nutrient absorption. Intralipid is made from soybean oil, egg yolk phospholipids, and glycerin, and it provides a mixture of both saturated and unsaturated fatty acids. It is administered through a central or peripheral vein, and its use is carefully monitored by healthcare professionals to ensure proper nutritional support and to avoid complications such as fat overload syndrome. Intralipid also plays a role in specific therapeutic applications, including as an antidote for certain drug overdoses and poisonings due to its ability to bind to lipophilic substances.
