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. They may be used for severe cases of gastroenteritis, especially if the patient is dehydrated. [1] [2]
There are few side effects related to the use of 5-HT 3 antagonists; the most common are constipation or diarrhea, headache, and dizziness. [28] Unlike antihistamines with antiemetic properties such as cyclizine, 5-HT 3 antagonists do not produce sedation, nor do they cause extrapyramidal effects, as phenothiazines (such as prochlorperazine ...
The most common typical antipsychotics associated with EPS are haloperidol and fluphenazine. [4] Atypical antipsychotics have lower D2 receptor affinity or higher serotonin 5-HT2A receptor affinity which lead to lower rates of EPS. [5] Other anti-dopaminergic drugs, like the antiemetic metoclopramide, can also result in extrapyramidal side ...

The antiemetic action of metoclopramide is due to its antagonist activity at D 2 receptors in the chemoreceptor trigger zone in the brain — this action prevents nausea and vomiting triggered by most stimuli. [34] At higher doses, 5-HT 3 antagonist activity may also contribute to the antiemetic effect. [35] [failed verification]
