Ondansetron is a selective inhibitor of the serotonin 5-HT3 receptor. The gastrointestinal tract lining, which controls the nausea and vomiting reflex, contains the 5-HT3 receptors. Serotonin is a neurotransmitter that binds to the 5-HT3 receptors and stimulates the vomiting reflex when released. By preventing the binding of serotonin to these receptors, ondansetron prevents and treats nausea and vomiting. This is because blocking the 5-HT3 receptors prevents serotonin from triggering the vomiting reflex. Ondansetron is a highly selective 5-HT3 receptor antagonist, and it is thought to reduce nausea and vomiting by blocking the action of serotonin on these receptors. This effect of ondansetron has led to its use in treating nausea and vomiting caused by chemotherapy, radiation therapy, and postoperatively.
