Antiemetic drugs are used to treat what symptom?

Nausea is the symptom antiemetic drugs target. These medications work by blocking signals in the brain and gut that trigger the vomiting reflex, such as dopamine receptors in the chemoreceptor trigger zone and serotonin receptors in the gut and brainstem. By dampening these pathways, they relieve the feeling of sickness and the urge to vomit, which is why they’re commonly used for nausea from motion, surgery, or chemotherapy. Dizziness, headache, and cough are not the primary symptoms treated by antiemetics, though some antiemetics may have ancillary effects in certain contexts.
