Pharmacological Properties

Ondansetron works by selectively inhibiting serotonin 5-HT₃ receptors located on vagal afferent nerves in the gastrointestinal tract and in the chemoreceptor trigger zone of the central nervous system. Serotonin release, which commonly occurs during chemotherapy or surgery, is a key trigger for nausea and vomiting. By blocking this pathway, Ondansetron prevents both the initiation and continuation of the emetic response.

The injectable route allows for rapid onset of action, making Onsat Injection suitable for acute management and prophylaxis of severe nausea and vomiting.
