Ondansetron is commonly used as what type of medication?

• A. Antiemetic
• B. Analgesic
• C. Antibiotic
• D. Anticoagulant

Answer: (A)

Ondansetron is used to prevent nausea and vomiting by blocking serotonin signals in both the gut and the brain’s chemoreceptor trigger zone. This action stops the reflex pathways that trigger the vomiting center, making it an antiemetic. It’s commonly given to reduce postoperative nausea and vomiting and to manage nausea from chemotherapy or radiation therapy. It’s not an analgesic, antibiotic, or anticoagulant, so those categories don’t describe its primary use. Side effects can include headache or constipation.
