Short General Description of Zofran:
Zofran is a medication commonly prescribed to prevent nausea and vomiting caused by chemotherapy, radiation therapy, and surgery. It belongs to a class of medications known as antiemetics and works by blocking the action of serotonin, a natural substance in the body that can trigger nausea and vomiting. Zofran is available in various forms, including tablets, oral disintegrating tablets (ODT), and oral solution.
Zofran is often used in cancer patients undergoing chemotherapy to help manage the side effects of the treatment. According to the American Cancer Society, about 650,000 cancer patients receive chemotherapy each year in the United States.
Studies have shown that Zofran can be effective in preventing nausea and vomiting in patients undergoing chemotherapy. In a clinical trial published in the Journal of Clinical Oncology, it was found that 76% of patients who received Zofran experienced no vomiting compared to 53% of those who did not receive it.
Zofran is also commonly used in pregnancy to treat morning sickness. According to statistics from the American Pregnancy Association, approximately 70-85% of pregnant women experience morning sickness during their first trimester. Zofran has been shown to be effective in reducing the symptoms of nausea and vomiting in pregnant women.
Overall, Zofran has become a widely used medication in the management of nausea and vomiting in various patient populations, making it an important tool in improving quality of life for those undergoing cancer treatment and pregnant women experiencing morning sickness.
