Granisetron is a selective 5-HT3 receptor antagonist used to manage nausea and vomiting, particularly associated with chemotherapy and radiation therapy. Chemically, it is a serotonin (5-HT) receptor antagonist with a specific affinity for the 5-HT3 subtype. By blocking the action of serotonin, especially in the gut and the central nervous system, granisetron helps alleviate nausea and vomiting by preventing the activation of the vomiting reflex. This drug is commonly prescribed to cancer patients undergoing chemotherapy or radiation to mitigate the side effects of nausea and vomiting. Granisetron is available in various formulations, including oral tablets and injectable forms, offering flexibility in its administration for different clinical scenarios. Its effectiveness in controlling chemotherapy-induced nausea and vomiting contributes significantly to improving the quality of life for cancer patients undergoing treatment.
