1. Ondansetron

   Ondansetron is a serotonin 5-HT3 receptor antagonist used mainly as an antiemetic, often following chemotherapy. It affects both peripheral and central nerves. Ondansetron reduces the activity of the vagus nerve, which deactivates the vomiting center in the medulla oblongata, and also blocks serotonin receptors in the chemoreceptor trigger zone. It has little effect on vomiting caused by motion sickness, and does not have any effect on dopamine receptors or muscarinic receptors.

1. Obstetrics Gynecology:

   I think it's also important to keep in mind that the risks of any medication -- whether it's ondansetron or any other medication -- need to be balanced against the risks of inadequate treatment or no treatment, particularly in those patients that have severe nausea and vomiting in pregnancy, or hyperemesis gravidarum, those conditions carry some real risks themselves -- dehydration, electrolyte abnormalities -- and a lot of these patients require admission to the hospital if they're not adequately treated.
