Category of medications used to treat nausea, vomiting, and motion sickness.

Drugs used to prevent or relieve nausea and vomiting, usually from motion sickness, gastroenteritis, morning sickness, and cancer. Four kinds of drugs are prescribed for nausea and vomiting; phenothiazines, antihistamines, anticholinergics, and selective serotonin antagonists. Phenothiazines work by depressing the central nervous system; antihistamines have a depressant effect on nerve pathways; anticholinergics inhibit nerve impulse transmissions; and serotonin antagonists block the stimulation that causes vomiting. The latter type of drug is often used to treat nausea and vomiting due to cancer chemotherapy. All are powerful drugs that act at one or more of the places in the body responsible for causing nausea and vomiting, and they must be taken with care.
