What is Ondansetron Hydrochloride

OndansetronThe Generic name of this drug

Treatment SummaryOndansetron is a drug that works by blocking certain serotonin receptors in the brain. It was approved by the FDA in 1991 and is available as a pill, a dissolving tablet, and an injection. It is used to prevent nausea and vomiting caused by chemotherapy, and has also been found to have calming and sedative effects. Recently, a new oral film form of ondansetron has been developed to make it easier for people experiencing nausea to take the medication.

Effectiveness

How Ondansetron Hydrochloride Affects PatientsOndansetron blocks the serotonin 5-HT<sub>3</sub> receptors in the body that are responsible for causing nausea and vomiting. Chemotherapy drugs can release serotonin from the intestines that trigger these symptoms, and ondansetron helps to counteract this. Studies have shown that taking ondansetron can lead to a slight increase in the time it takes for electrical signals to travel through the heart, but this effect has not been seen in those taking it orally. Additionally, it has been found to have no effect on esophageal and gastric motility, lower esophageal sph

How Ondansetron Hydrochloride works in the bodyOndansetron works by blocking a reflex in the body caused by serotonin. Serotonin is a chemical released from cells in the small intestine, which can cause nausea and vomiting. Ondansetron blocks this reflex by blocking the serotonin receptors, located on neurons in the peripheral and central nervous systems. While it seems to work for post-operative and chemotherapy-induced nausea and vomiting, it is not yet known how it affects opiate-induced emesis.
