Learning Objectives

At the end of this lecture, the student will be able to:

• Define: Emetics

• Explain the monograph analysis of:

 Copper sulphate

 Antimony potassium tartarate

Emetics

Definition: Emetics are the agents which induces vomiting. Used for treating poisoning cases

Emetics drugs, in simple terms, are substances that trigger vomiting. While the concept may sound straightforward, the history and evolution of these drugs have been anything but simple.

Originally, emetics were employed for various purposes, including ritualistic and symbolic practices. Today, their use is more refined, often confined to medical settings.

Mechanism of action:

• They may act directly on the gastrointestinal tract bringing about emesis through local irritation effect. Ex: ammonium carbonate

    • Ipecac syrup derived from the roots of the ipecac plant. It stimulates the vomiting reflex and has historically been used in cases of poisoning.
  2. Apomorphine
    • Apomorphine commonly administered through injection. It acts on the dopamine receptors in the brain, triggering the vomiting reflex.
  3. Hydrogen Peroxide
    • In certain emergencies, hydrogen peroxide may be used as an emetic agent. It releases oxygen and irritates the stomach lining, inducing vomiting.
  4. Copper Sulfate
    • Copper sulfate is another chemical agent with emetic properties. It can be employed in specific situations to prompt vomiting.
