Zofran, our superhero, is always facing villains that cause terrible injustices like nausea and vomiting. The villains chemotherapy, radiation therapy, and surgery are the biggest culprits. The therapeutic class for Zofran is anti-emetic.
How does Zofran work?
Zofran is a Serotonin (5-HT3) receptor antagonist. It will block the vomiting reflex by inhibiting 5-HT3 receptors in the vomiting center, the chemoreceptor trigger zone and in the small intestine.
The medication works in the stomach to block the signals to the brain that cause nausea and vomiting.
That’s a good thing.
