Ondansetron is an antiemetic medication used to prevent nausea and vomiting. It works by blocking serotonin receptors in the brain, reducing the urge to vomit. Ondansetron may cause side effects such as headache and constipation. In summary, Ondansetron is crucial for managing nausea.
Ondansetron acts as a selective serotonin 5-HT3 receptor antagonist, inhibiting the action of serotonin in the chemoreceptor trigger zone and preventing nausea and vomiting.
