How It Works (Mechanism of Action)
Ondansetron works by blocking the action of serotonin, a natural substance in the body that can cause nausea and vomiting. This helps to prevent these symptoms in patients undergoing treatments like chemotherapy or surgery.
Scientifically, Ondansetron is a selective serotonin 5-HT3 receptor antagonist. It binds to the 5-HT3 receptors located in the central nervous system and the gastrointestinal tract, inhibiting the emetic response triggered by serotonin release.
