SETOFILM is a pharmaceutical product commonly used to prevent and treat nausea and vomiting caused by various conditions, including chemotherapy, radiation therapy, and surgery. Its active ingredient is ondansetron, which belongs to a class of medications known as serotonin 5-HT3 receptor antagonists. These drugs work by blocking the action of serotonin, a natural substance in the body that can cause vomiting. SETOFILM is typically available in the form of orally disintegrating tablets, making it easy to administer without the need for water, which can be particularly beneficial for patients struggling with nausea. It is widely prescribed due to its effectiveness in controlling symptoms of nausea and vomiting, improving the quality of life for patients undergoing treatments that can cause these distressing side effects.
