Lipid emulsion
Lipid Emulsion
Lipid emulsion (pronunciation: /ˈlɪpɪd ɪˈmʌlʃən/) is a medical treatment primarily used in the management of certain types of poisoning and overdose. The term "lipid" is derived from the Greek word "lipos," which means fat, and "emulsion" comes from the Latin word "emulgere," meaning to milk out, referring to the process of mixing two immiscible substances.
Definition
A lipid emulsion is a fat-based solution that is used in medicine to provide essential fatty acids and calories to patients who cannot get these nutrients from their diets. It is also used as an antidote in certain cases of drug toxicity.
Uses
Lipid emulsions are used in a variety of medical contexts. They are often used in parenteral nutrition to provide essential nutrients to patients who cannot eat or absorb nutrients from their gut. They are also used as an antidote in cases of toxicity from fat-soluble drugs, such as local anesthetics.
Mechanism of Action
The exact mechanism of action of lipid emulsion therapy is not fully understood. However, it is believed that the lipid emulsion acts as a "lipid sink," drawing the toxic drug away from the target organs and into the lipid phase, where it is then metabolized and excreted.
