EMETICS Meaning and
Definition
-
Emetics are substances or medications that are used to induce vomiting. They act on the body's natural reflexes to trigger the expulsion of stomach contents through the mouth. This process can neutralize or eliminate toxic substances that have been ingested, thus preventing their absorption into the bloodstream.
Emetics function by irritating the stomach lining or stimulating the chemosensitive zone in the brain, which sends signals to the vomiting center. This, in turn, activates the muscles involved in the vomiting reflex, such as the diaphragm and abdominal muscles. As a result, the individual experiences an urge to vomit and expels the contents of their stomach.
These substances can be of both natural and synthetic origin. Historically, emetics derived from various plants, such as ipecacuanha and lobelia, were commonly used. However, synthetic emetics have largely replaced these natural sources due to their more predictable and controlled effects. Commonly used synthetic emetics include apomorphine, syrup of ipecac, and a medication known as hydroxyethyl starch.
Emetics have several applications in medicine, including the management of certain types of poisoning, accidental ingestion of toxic substances, and gastric emptying in emergency situations. However, their use should always be under the guidance of a healthcare professional to ensure proper dosage and to consider any potential risks or contraindications.
