Study Notes
Serotonin-3 Receptor Antagonists
- Serotonin-3 receptor antagonists, such as ondansetron, work by blocking the serotonin receptors in the gut and the central nervous system, thereby reducing nausea and vomiting.
Adverse Events
- Common adverse events associated with the use of serotonin-3 receptor antagonists include headache, constipation, and dizziness.
Efficacy
- Dolasetron, granisetron, ondansetron, and palonosetron are considered to have similar efficacy in preventing chemotherapy-induced nausea and vomiting.
Factors Influencing Drug Choice
- The antiemetic drug of choice among dolasetron, granisetron, ondansetron, and palonosetron is often determined by their differing half-lives and dosage regimens.
Dosage Forms
- In addition to oral and parenteral forms, ondansetron is also available in a soluble film formulation.
