What is ondansetron oral disintegrating tablet, and how does it work (mechanism of action)?
Ondansetron is an anti-nausea medication most often used to prevent nausea and vomiting caused by chemotherapy. Chemotherapy agents increase secretion of serotonin which stimulates serotonin (5-HT3) receptors in the brain, causing nausea and vomiting. Ondansetron works by selectively blocking serotonin (5-HT3) receptors, reducing the effect of increased serotonin due to chemotherapy. The FDA approved ondansetron in December 1992.
