Antiémétique

Antiémétique is a term used to describe a drug that is effective against vomiting and nausea. These medications, also known as anti-nausea drugs, work by targeting the parts of the brain and body that trigger the vomiting reflex. They can be prescribed for a variety of conditions, including motion sickness, chemotherapy-induced nausea and vomiting, pregnancy-related nausea (morning sickness), and post-operative nausea and vomiting.

There are several classes of anti-emetics, each with a different mechanism of action. Some common classes include serotonin receptor antagonists (like ondansetron), dopamine antagonists (like metoclopramide), antihistamines (like dimenhydrinate), and corticosteroids. The choice of anti-emetic depends on the cause and severity of the nausea and vomiting, as well as individual patient factors.

Anti-emetics can be administered in various forms, including oral tablets, capsules, suppositories, injections, and patches. Side effects can vary depending on the specific drug, but may include drowsiness, dizziness, constipation, or diarrhea. It is important to consult a healthcare professional to determine the most appropriate anti-emetic and dosage for a particular situation. Self-medication with strong anti-emetics is not recommended.
