Antiemetics

Topic: Pharmacology

Drugs that prevent or relieve nausea and vomiting through different pathways: serotonin 5-HT3 antagonists (e.g., ondansetron), dopamine antagonists (e.g., metoclopramide), antihistamines, NK1 antagonists and corticosteroids. The choice depends on the cause, such as chemotherapy, surgery, pregnancy or motion. Ondansetron can prolong the QT interval and cause constipation, dopamine antagonists can cause extrapyramidal symptoms, and many cause drowsiness. Give them before a predictable trigger such as chemotherapy, assess fluid and electrolyte status, and prevent falls in sedated clients.
