An emetic is used to induce vomiting. An emetic is used medically where a substance has been ingested and must be expelled from the body immediately. Inducing vomiting can remove the substance before it is absorbed into the body.
Emetics are used to counteract the effects of poisoning and to treat chronic alcoholism. For example, an injection of apomorphine combined with ingestion of alcohol leads to a conditioned reflex causing the taste and odor of alcohol to induce vomiting. When taken in small doses, emetics act as expectorants.
Emetics are distinguished according to whether they act on the vomiting center in the brain or whether they irritate the mucous membrane of the stomach and excite the stomach's vomiting center.
Direct, or gastric, emetics, (like syrup of ipecac), is a substance that induces vomiting when administered orally. Syrup of ipecac is a drug obtained from the dried roots of Cephaelis (or Psychotria) ipecacuanha, a creeping shrub, native to Brazil.
Indirect, or systemic, emetics, such as apomorphine, induce vomiting by acting indirectly through the blood on the brain center that controls vomiting.
Emetics are not used to treat poisoning by strong acids or alkalis, petroleum distillates such as kerosene, or substances causing convulsions.
