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.

The first-generation 5-HT 3 receptor antagonist (ondansetron, dolasetron, granisetron, and tropisetron) have been the most important drugs in antiemetic therapy for emetogenic chemotherapy. They are especially effective in treating acute emesis, occurring in the first 24 hours following chemotherapy. [38]
Dopamine receptor flow chart. Dopamine receptors are all G protein–coupled receptors, and are divided into two classes based on which G-protein they are coupled to. [1] The D 1-like class of dopamine receptors is coupled to Gα s/olf and stimulates adenylate cyclase production, whereas the D 2-like class is coupled to Gα i/o and thus inhibits adenylate cyclase production.

The antiemetic medications can block the binding site on a chemoreceptor in the CTZ, so that the emetic agent cannot bind to it to cause its emetic effects. [6] Another way that antiemetic medications can work is by binding to a chemoreceptor in the CTZ, but instead of initiate vomiting, the medication can cause the receptors to send signals to ...
Vistaril (hydroxyzine) – an antihistamine for the treatment of itches and irritations, an antiemetic, as a weak analgesic, an opioid potentiator, and as an anxiolytic; Vyvanse (lisdexamfetamine) – a pro-drug stimulant used to treat attention deficit hyperactivity disorder and binge eating disorder; Vyvanse is converted into Dexedrine in vivo
These drugs have antipsychotic and, often, antiemetic properties, although they may also cause severe side effects such as extrapyramidal symptoms (including akathisia and tardive dyskinesia), hyperprolactinaemia, and the rare but potentially fatal neuroleptic malignant syndrome, as well as substantial weight gain.
