Zofran is categorized as what type of medication?

• A. Antiemetic
• B. Antibiotic
• C. Antihistamine
• D. Laxative

Answer: (A)

This item tests your ability to classify a medication by its therapeutic use. Zofran (ondansetron) is used to prevent nausea and vomiting, especially around chemotherapy or after surgery, so it belongs to the antiemetic group. It works by blocking serotonin receptors involved in triggering the vomiting reflex, both in the gut and in the brain. That mechanism is specific to stopping nausea, not fighting infection, blocking histamine for allergy symptoms, or promoting bowel movements. Therefore, it is not an antibiotic, not an antihistamine, and not a laxative.
