Study Notes
Serotonin Receptor Antagonists
- Ondansetron is the prototype medication for serotonin receptor antagonists.
- These antagonists primarily block serotonin receptors located in the chemoreceptor trigger zone (CTZ), the upper gastrointestinal tract, and the vomiting center in the brain.
- Common clinical applications include managing chemotherapy-induced nausea and vomiting, and preventing nausea and vomiting around surgical procedures.
- Serotonin receptor antagonists do not block dopamine receptors within the extrapyramidal system; they specifically target serotonin receptors.
- Ondansetron can be administered via oral (PO) or intravenous (IV) routes.
- Side effects associated with ondansetron include headaches, dizziness, and fatigue.
