Uses and Medical Indications of Zoron 4 mg

How Zoron Works

Zoron works by blocking serotonin (5-HT3) receptors located in both the gastrointestinal tract and the central nervous system. During chemotherapy or surgery, serotonin is released and activates these receptors, triggering nausea and vomiting. By inhibiting this pathway, Zoron effectively prevents the emetic response.
