Onseron Syrup 50 ml – Ondansetron for Effective Nausea and Vomiting Relief
Onseron Syrup 50 ml contains Ondansetron, a powerful antiemetic medicine used to prevent and treat nausea and vomiting associated with cytotoxic chemotherapy, radiotherapy, and surgery. Ondansetron works by blocking serotonin (5-HT3) receptors in the central and peripheral nervous systems, which are responsible for triggering the vomiting reflex after serotonin release from enterochromaffin cells during therapy.
By selectively antagonizing these receptors, Onseron effectively prevents the initiation of the vomiting reflex and reduces the severity of nausea in patients undergoing cancer treatment or post-surgery recovery. Its liquid form ensures easy administration for both adults and children who cannot swallow tablets.
