Emetics. Medicines which induce vomiting. The principal emetics are ipecacuanha and tartarized antimony, and their preparations; and the sulphates of zinc and copper. Ipecacuanha is usually administered in substance or infused in wine. The use of tartar emetic and antimonial wine is generally followed by nausea, relaxation of muscular power and of the circulation. Sulphate of zinc acts promptly and energetically, and its effects cease as soon as ejected from the stomach; hence it is employed to eject poison. Sulphate of copper is more violent and disagreeable, and its intense metallic taste is a great objection to its use. The operation of emetics is powerfully promoted by drinking copiously of diluents, especially of warm or tepid water. This latter is itself an emetic when taken in quantity. Its use prevents, in a great degree, excessive straining accompanying vomiting.
