Ondansetron does antagonize (block) a specific serotonin receptor that is different from any of the antidepressants or neuroleptic antipsychotics. While these latter drugs antagonize 5-HT2a receptors, ondansetran antagonizes 5-HT3 receptors. Reducing the activity of these serotonin neurons sometimes helps to relieve nausea and vomiting, particularly after surgery.
