Q. Are antiemetic drugs effective?

Answer

An antiemetic drug is a medication that relieves nausea and vomiting. A comprehensive study found that serotonin antagonists (ondansetron, granisetron, and tropisetron), as well as dexamethasone, droperidol, and cyclizine, were more effective than placebo in treating postoperative nausea and vomiting. Certain antiemetic drugs may need to be avoided depending on the clinical circumstances.
