Mechanism of action

Ondansetron is a selective 5-HT3 receptor antagonist that works locally when instilled into the peritoneal cavity during lavage procedures. By blocking serotonin signaling at chemoreceptor trigger zone and vagal afferent pathways, it reduces the emetogenic stimulus associated with peritoneal manipulation and fluid instillation. This local application may provide targeted antiemetic effects with potentially reduced systemic exposure compared to parenteral administration.
