By blocking 5‑HT3 receptors, the brain’s nausea pathway is dampened.
Ondansetron selectively blocks 5‑HT3 (serotonin) receptors on vagal afferents in the gut and in the chemoreceptor trigger zone, reducing the emetic signaling that leads to nausea and vomiting. This receptor antagonism helps children keep down fluids during recovery.
