Final answer:
Drugs designed to cause vomiting are known as Emetics. They are used to induce vomiting in cases such as poisoning to prevent substance absorption in the digestive system.
Step-by-step explanation:
Drugs designed to cause vomiting are called Emetics. These medications are typically used to induce vomiting in cases of poisoning or overdose, to rid the stomach of harmful substances before they can be absorbed into the bloodstream. The act of vomiting, or emesis, is a forceful expulsion of the contents of the stomach through the mouth, often triggered by irritants in the digestive tract. A common clinical scenario where an emetic might be used is when a person comes down with the flu, which might lead to emesis due to the presence of a virus affecting the digestive system. Emetics are substances that induce vomiting and are commonly used in cases of poisoning or drug overdose to remove the toxic substance from the body. Examples of emetics include ipecac syrup and apomorphine.
