Zofran

Ondansetron, or commonly known as zofran, belongs to a class of drugs known as serotonin 5-HT3 receptor antagonists. It works by blocking the action of serotonin, a natural substance that may cause nausea and vomiting, at the 5-HT3 receptors in the brain and gastrointestinal tract. By inhibiting these receptors, ondansetron effectively reduces the incidence of nausea and vomiting. When given Intravenously, the benefits are usually seen rapidly. Available via IV or IM.
