emetics vomiting

Emetic, substance used to induce vomiting. Emetics are of 2 main types. Centrally acting emetics stimulate the nerve center that controls vomiting. Apomorphine and picrotoxin are the best examples. Reflex-action emetics, including copper sulfate, mustard, ipecac, and solutions of common salt, irritate the mucous membrane of the stomach. Emetics are used primarily as emergency measures in cases of serious poisoning and acute indigestion.
