Glendan 2mg/5ml Syrup contains Ondansetron, a selective 5-HT3 receptor antagonist used primarily to prevent nausea and vomiting caused by chemotherapy, radiotherapy, and surgery. Each 5ml of the syrup formulation delivers 2mg of Ondansetron, making it suitable for pediatric and adult patients who require an oral liquid dosage form. Ondansetron works by blocking serotonin receptors centrally in the chemoreceptor trigger zone and peripherally in the gastrointestinal tract, thereby inhibiting the emetic signals. Glendan syrup is indicated for the management of acute and delayed nausea and vomiting associated with cancer treatments and postoperative recovery. It is generally well-tolerated, with common adverse effects including headache, constipation, and dizziness. The syrup formulation allows for flexible dosing, particularly in patients unable to swallow tablets. Dosage should be individualized based on the patient’s clinical condition, age, and response to therapy. Caution is advised in patients with hepatic impairment, and it should be used under medical supervision. Glendan 2mg/5ml Syrup is a valuable antiemetic agent that improves patient comfort and compliance during treatment regimens associated with emesis.
