Osetron Injection 8 mg/4 ml contains Ondansetron, a selective serotonin 5-HT3 receptor antagonist, formulated for intravenous administration. It is used for the prevention and treatment of nausea and vomiting associated with chemotherapy, radiotherapy, and surgery. Ondansetron works by blocking the action of serotonin, a key neurotransmitter that triggers the vomiting reflex. The injectable form allows rapid onset of action, making it ideal for patients who cannot take oral medication or require immediate relief.
