Which medication is commonly prescribed for chemotherapy-induced nausea?

Ondansetron is commonly prescribed for chemotherapy-induced nausea due to its effectiveness as a serotonin 5-HT3 receptor antagonist. This class of medication works by blocking the action of serotonin, a natural substance in the body that can cause nausea and vomiting, particularly in response to chemotherapy. By inhibiting these receptors in the gastrointestinal tract and central nervous system, ondansetron significantly reduces the incidence and severity of nausea and vomiting, making it a first-line option for patients undergoing cancer treatment.

While other medications, such as aprepitant, metoclopramide, and prochlorperazine, can also be used to manage nausea, ondansetron is specifically renowned for its role in preventing nausea induced by chemotherapy, especially in the acute phase following treatment. This makes it a particularly important medication in oncological care for improving patients' quality of life during treatment.
