Mechanism of Action
Ondansetron is a highly selective serotonin 5-HT3 receptor antagonist. Serotonin (5-HT) is released by enterochromaffin cells in the gastrointestinal tract in response to chemotherapy, radiation, or surgical stimuli. This serotonin then binds to 5-HT3 receptors located on vagal afferent nerve terminals in the gut and on chemoreceptor trigger zone (CTZ) neurons in the area postrema of the brain. By competitively blocking these 5-HT3 receptors, ondansetron prevents the transmission of nausea and vomiting signals to the vomiting center in the brainstem. Unlike other antiemetics, ondansetron does not cause significant extrapyramidal side effects or sedation.

Convenient oral tablet formulation.

Key Warnings and Contraindications
Hypersensitivity: Contraindicated in patients with known hypersensitivity to ondansetron or any excipients.
QT Prolongation: Use with caution in patients with congenital long QT syndrome or electrolyte abnormalities, as ondansetron can cause dose-related QT interval prolongation.
