Is ondansetron a opiate

No, ondansetron is not an opiate. It is an antiemetic medication primarily used to prevent nausea and vomiting caused by chemotherapy, radiation therapy, or surgery. Ondansetron works by blocking the action of serotonin, a neurotransmitter, in the brain and gut. Unlike opiates, which are pain-relieving drugs derived from opium, ondansetron does not have pain-relieving properties and is not classified as a controlled substance.
