An antiemetic is a drug that is effective against vomiting and nausea. Antiemetics are typically used to treat motion sickness and the side effects of opioid analgesics, general anaesthetics, and chemotherapy directed against cancer.
Is a centrally acting emetic?
Centrally acting antiemetics are generally much more effective than peripheral-acting antiemetics. Centrally acting antiemetics that work on the medullary vomiting center are often more effective than those that act just at the chemoreceptor trigger zone.
When do you use antiemetics?
Drug treatment Antiemetics are generally only prescribed when the cause of vomiting is known because otherwise, they may delay diagnosis, particularly in children. If antiemetic drug treatment is indicated, the drug is chosen according to the aetiology of vomiting.

What are antiemetics and how do they work?
How do antiemetics work? Antiemetics work on the neural pathways involved with vomiting by blocking specific receptors that respond to neurotransmitter molecules, such as serotonin, dopamine, and histamine. Most of these are central receptors found in the vomiting center of the brainstem, while peripheral receptors are found in the vagus nerve.
How do centrally acting antiadrenergic agents work?
Centrally acting antiadrenergic agents inhibit the stimulation of the central nervous system alpha-adrenergic receptors and decrease sympathetic stimulation to the blood vessels and the heart. They block the release and action of catecholamines (epinephrine, norepinephrine, dopamine), which are released in response to stress.
How does antihistemetics work?
Antiemetics work on the neural pathways involved with vomiting by blocking specific receptors that respond to neurotransmitter molecules, such as serotonin, dopamine, and histamine. Most of these are central receptors found in the vomiting center of the brainstem, while peripheral receptors are found in the vagus nerve.
